New goals,well-established certainties

The Ladurner Ambiente Group’s strate-gic policy was developed with the ap-proved and current development plan that tended, as noted, to focus action on the core business, bringing industry to the heart of its operations.

Ladurner focused its efforts on its business, which is linked to system solutions that give true added value to problems related to the treatment of muni-cipal waste, its development and material recovery and, at the same time, the recovery of energy re-sources.All is performed with expertise that is not improvi-sed. Instead it comes from twenty-five years of en-trepreneurial history and direct experience applied to special and extreme situations, while seeking the appropriate compromise with the existing con-ditions in the area, adapting the technology and its use to the individual situations.

But above all, the company is flexible and uses various technologies that can be adapted to the individual situation not only in Italy, but also inter-nationally.Ladurner has always had favourable relationships with foreign partners and suppliers, contributing to the development of technologies on the domestic market that came from far away locations and from experience and reliability of the technical solutions.For this reason, now that it is important and neces-sary for an expanding industrial group to broaden its horizons beyond the domestic market and out-side of Europe, this experience and expertise be-come fundamental for meeting these challenges.

A company’s entrepreneurial capacity depends on commercial, relational, administrative and financial expertise along with technical expertise.Development and internationalization are another one of the Group’s guidelines. As CEO Andrea Silvestri tells us on page 3, the commercial deve-lopment activity in both Italy and abroad is very in-tense. While the duly selected domestic market is still interesting, Ladurner is also looking and opera-ting abroad with commercial activities and partner-ship agreements for waste treatment facilities.

The first major foreign contracts have been com-pleted or are in progress. With the positive com-pletion of the contract with Cluj, in Romania, the Ladurner technical structure now has a new and fa-scinating challenge, just a little more to the northe-ast. We are talking about the design and creation of the new waste treatment plant in the city of Vilnius, the capital of Lithuania. Massimo Mapelli, Director of the Technical Office, discusses it with us (page 12), emphasizing how the Bolzano engineering facilities, while far from the Lithuanian capital, are functioning as a “thinking head” for the technolo-gical part of the project. In view of international de-velopment, Ladurner’s skill and experience in the field of unsorted waste and the achievement of the objective, and standard, for the “end of waste” are important. We discuss it with Massimo Troncon, Sales Manager, on page 4; Burkhard Klotz, CEO and Technical Manager of Ladurner Impianti, on page 6 and Simone Paoli, Business Development Manager, on page 7.Naturally, the domestic market continues in full

swing. On the organic waste front, while the Albai-rate digestion plant is now fully functional (Abram discusses it on page 14), the authorization process is under way for the Cupello, Abruzzo project for a digestion plant for biomethane production. Me-anwhile, in Tortona, the revamping work is about to be completed for the construction of another di-gestion plant. These are two more important con-tracts in Ladurner’s energy chain “grid” just as the Montale (waste-to-energy incinerator) and Eboli (composting) contracts are in the management grid.The “alternative” core business such as reclama-tions (Valle discusses the dump in Cremona on page 19) or the “Lighted Pathway” in the Venice lagoon (Bagnacani on page 17) is not being ne-glected. As we can see, the Ladurner business is on the go, aspiring to new milestones, being able to count on the “old” and established certainties.

Why Expo?

W hy would a company like Ladurner parti-cipate at Expo? Well, because those who make Sustainability and the Environment their re-ason for existing must not miss this event.Because the theme of “Feeding the planet” can-not overlook how we must take and give back the material, water and energy resources we will use to produce this nourishment.Because the Circular Economy theme cannot be separated from the best practices used to create it and cannot only be a slogan without concrete and practical applications that are both industrial-ly and economically sustainable.Because a World Expo is a unique occasion to show the world what a country is capable of doing better. And we are sure that in Italy there are examples that can be exported throughout the world, even in areas in which we are usually considered to be perpetually inadequate. That is not the case and we are here to prove it.And finally, because Expo is our stepping sto-ne to the world. As you can see, we are ready to demonstrate what we know how to do and to welcome your representatives and your requests. Come see us at our three focal events but also daily at CasaAltoAdige because although it is true that we look at the world, we must never forget our roots.

Enjoy the EXPO!

A conversation with the CEO of Ladurner Ambiente Group, Andrea Silvestri

“Development and internationalization” are the themes that the Ladurner Group intends to expand upon in the near future. We discuss them with Andrea Silvestri, asking him for more information on their activities.

So, “development and internationalization” is a buzzword or is it more? “The themes,” states Silvestri, “may seem obvious and trivial given

the crisis in the domestic market and may be generated by the need to sur-vive for companies that are forced to choose them in order to avoid being overcome. For the Ladurner group, on the other hand, they are the natural consequence of the group’s reason for being.”

Explain it for us.“Ladurner has always maintained constant and established relationships with foreign groups, not only in the German area (Germany, Austria and Switzerland) and throughout Europe (Finland, the Netherlands, etc.), but also in the United States and Asia (especially in Japan and China), contribu-ting to the technological development that it then introduced and developed with particular success in the domestic market. These technologies were first applied to their systems starting in the end of the 90s and were then improved, implemented and applied, giving them their own expertise.

And this particularly affected everything relating to the implementation of the plant engineering, from design to construction, to be able to give the customer the best technology available, once tested, proven and matured in the field.”

But Ladurner’s experience is not limited to plant engineering techno-logy. “In fact,” continued Andrea Silvestri, “at the same time, Ladurner also deve-loped experience in running this type of plant, becoming an expert in mana-gement and maintenance, a very important added value in both the startup and in-service.”

So Ladurner Group has operated on this basis so far in the domestic market?“Yes. These two factors combined with a growing domestic market over the last decade have, on one hand, led the group to focus its business in Italy and, on the other hand, to neglect the opportunities being created in other world markets.”

Maybe the time was not yet ripe?“That’s part of it,” said Silvestri, “but the time now seems ripe and favoura-

ble for foreign business development and once again Ladurner is ready with technology and experience to be able to participate in competition on the international scale with knowledge of the facts, entrepreneurial drive and acquired and demonstrable experience.”

So Ladurner is able to give real responses, even in the international field? “The available technologies are the group’s assets and are of such magnitu-de that they combine well with the demands of new markets. In fact, Ladur-ner can offer a wide range of solutions depending on local needs and adapt the proposal with technical and management training for the time needed or set by the tenders.”

More concretely? “With these conditions, Ladurner is finalising structured agreements with le-ading Italian and foreign companies that have complementary and synergi-stic characteristics for this purpose, with the goal being strong and effective actions in new markets.”

Has there already been feedback?“The first results,” continued Andrea Silvestri, “are encouraging and among these include the awarding of the contract from the city of Vilnius, capital of Lithuania, for the construction of a mechanical biological treatment plant, MBT, worth approximately 30 million Euros and the MBT plant for the City of Cluj, Romania.”

And outside of Europe? “In India, two PPPs (Public Private Partnerships) were awarded in the di-sposal and utilisation of mixed waste industry, in a joint venture with the international company, Jindal.”

For the future, will there only be foreign development?“Commercial development activity in both Italy and abroad is very intense. The domestic market is still interesting, but it must be well-selected and we must operate with targeted actions. There are negotiations under way for waste treatment plants in all countries and on all continents, from Israel to South Africa to China.

Which country would you bet on?“Considering the enormous environmental problems linked with heavy indu-strial growth and the number of inhabitants, I would doubtless choose Chi-na. We have maintained excellent technological and commercial relationship with the country for years and we expect to finalize major contracts already within this fiscal year.”

RDF? We are ready!

by MassiMo Troncon

Another important step towards the “end of waste” directives in Italy: the Ladurner Group has acquired the expertise to prepare for this new opportunity, even in world markets.

Our country has been discussing the possibility of a greater use of RDF “waste-derived fuels” for quite some time with the dual purpose of using a potentially renewable resource and at the same time contribute to resolving the age-old problem of municipal and special non-hazardous waste by closing the virtuous circle of sorted waste as an alternative to the dump.

A further step was recently made in this direction. With the decree by the Ministry of the Environment and Protection of the Territory and Sea no. 22 dated February 14, 2013, whose subject was the specific criteria to be met so that certain types of SSF (secondary solid fuel), the old RDF, are excluded from the waste classification, Italy has taken a first step towards the “End of Waste” directives (and principles).

The declination of the traditional RDF in SSF is intended to qualify and cer-tify even more material being produced in different installations for quite some time. The new standard is considered an ideal tool for making sure the production and use of certain type of secondary solid fuels (SSF) is done in strict compliance with the standards for the protection of the environment and human health by combining environmental benefits with economic be-nefits and benefits for the community. The new regulation establishes pro-cedures and methods so that the SSF production and use phases, including the preparatory stages, proceed without endangering human health and wi-thout harming the environment. The regulation can be applied to SSF-Fuel,

defined by the legislature as “the sublot of secondary solid fuel (SSF) for which a declaration of conformity is issued” and the use of it as fuel in ce-ment factories and power plants for the production of electrical or thermal energy. Cement plant refers to a cement manufacturing plant with a produc-tion capacity exceeding 500 tons/day of clinker and power plant refers to a combustion plant with thermal combustion capacity of over 50 MW, and both must be in possession of Integrated Environmental Authorization (IEA) provided that they have environmental quality certification according to UNI EN ISO 14001 or, alternatively, registration in a Eco-Management and Audit Scheme (EMAS).

For the production of SSF-Fuel, only municipal and special waste can be used, provided that it is not hazardous. Although some non-hazardous wa-stes are not accepted, materials not classified as waste may be used, pro-vided they are not hazardous under the regulations on the classification, labelling and packaging of substances and mixtures. Therefore, SSF ceases to be classified as waste by issuing the Declaration of Conformity in com-pliance with the regulations. It is no longer covered by the rules regarding waste, unless it re-enters when it is no longer in compliance with the clas-sification set forth in UNI EN 15359 “Solid Recovered Fuels” (SRF). This standard determines SSF classification at the European level, taking into account three parameters (and related classes) recognized to be strategic for the environment, technology and performance/economy, such as NCV

net calorific value (commercial parameter), Cl (process parameter) and Hg (environmental parameter). The secondary solid fuel (SSF) category set forth in Article 183 Letter cc) of Legislative Decree no. 152 of 2006 was introduced into Italian Law by UNI EN/ TS 15359 and Legislative Decree 205/2010.

It replaces the RDF (refuse derived fuel) and RDF-Q (high quality refuse de-rived fuel) referred to in UNI 9903/1 and derived from municipal and special non-hazardous waste. The SSF is comprised of: a dry fraction separated using mechanical systems for municipal waste collected in an unseparated and/or biodried waste; waste from the selection of separate waste selection, in other words, the part not intended for recycling. It can also contain up to 50% by weight of waste declared assimilated for the purposes of recovery such as: non-chlorinated plastics; polylaminates (cartons for milk, wine, fruit juice, etc.); non-chlorinated synthetic rubbers; resins and artificial and syn-thetic fibres with a Cl content of

Quality RDF promoted by EnelThe Venice plant is Ladurner’s flagship because it represents one of the best practices in the field of waste treatment.

by siMone PaoLi

The Venice area has already been using a cutting edge waste tre-atment plant for seve-ral years. At the Venice Waste Treatment Fa-

cility, the Municipal Solid Waste that is collected is subjected to mechanical-biological treatment and processed into Refuse Deri-ved Fuel (RDF), enhanced throu-gh co-combustion with carbon in the adjacent Venice power plant. In the beginning it was one of those technical challenges that

are fascinating to those who work in the waste industry: the design and construction of a plant that uses the best waste biostabilization techno-logy for the production of quality RDF that could act as a substitute for coal.Today, this challenge is a crowning achievement for Ladurner, which ma-nages the Venice plant for Ecoprogetto Venezia. The plant has two RDF production lines. The first was built in 2001 and the second in 2010 fol-lowing the dismantling of the previously built composting plant. The ove-rall capacity of the plant is currently 265,000 t/year.RDF production is broken down into 4 primary stages:

Step 1: Reception and pre-treatment of unsorted waste.

Step 2: Biodrying in Ladurner biocells.The core of the treatment is biostabilization that occurs inside the herme-tically sealed concrete structures. During the process, the material has a 30% weight loss following the dehumidification, sanitation and biostabili-zation processes on the organic fraction present in the waste.The aerobic treatment lasts seven days while the biological process starts a few hours after the roof of the biocells is closed.The calorific value of the material coming out of the biocells, equal to about 12,000+13,000 Kj/kg, is about 35% more than the incoming waste. A dedicated software independently regulates the optimal air mixture to be blown inside each biocell by detecting the various control parameters and comparing them to the preset values.The seven days of material treatment are then broken down into 3 stages:1. start of the process with temperature increase from room temperatu-

re to operating temperature;2. biodrying at the constant temperature;3. cooling the waste with further humidity elimination

Step 3: Selection and mechanical treatmentThe dried and stabilized material is sent to the selection and mechanical treatment step.Thanks to a complex system of sieves and further refining, the following products are obtained from the selection cycle:

- RDF for energy use- Non-ferrous metals to send for recycling- Ferrous metals to send for recycling- Inert material (gravel, sand, glass, ceramic, etc.) to send for reuse or

to the dump.The RDF obtained is an excellent fuel with a calorific value of about 17,000 Kj/Kg.

Step 4: PackagingThe RDF is produced and packaged in three different ways:- Fluff RDF, which is the basic product and is a light material with a

particle size of less than 55 mm;- Pelletized RDF, obtained through an extrusion process and compres-

sed into pellets with a diameter of 16-18 mm and a length of about 20 mm;

- RDF in bales, pressed and then tied with a polyester strap and wrap-ped in polyethylene.

The total fluff RDF produced is then sent to the Enel power plant for co-combustion. To date, Enel uses 70,000 tonnes of RDF in its Palladio po-wer plant, thus replacing 5% of the coal used to supply the boilers (this is the first case in Italy and one of the primary case histories in Europe).

biocells

Ladurner biocells allow for a restricted cycle of intensive bio-oxidation (7 days). The diagram shows us how the process air is sucked from the upper part of the biocell to be recirculated from the bottom. The supply of oxygen is ensured by the introduction of fresh air by controlled dosage. The heat exchangers allow the process air to maintain a constant temperature that is ideal for bio-oxidation.

VeniceIn honour and in connection with EXPO 2015, Ladurner will organize the open day event at the RDF production plant in Venice.

Two tons of waste fuel ensures the electrical consumption of

one family: 70,000 tons of rdF are, therefore, enough to supply

electricity to 35,000 families, equal to the annual amount needed

for the entire historic centre of Venice.

After years of management we can say that the experience in Venice is one of the best practices in the waste treatment field. RDF co-combustion in carbon power plants is, in fact, a very interesting option due not only to the excellent compatibility RDF demonstrates when used in industrial plants but especially for its high energy yield, which ensures an extremely positive environmental balance. The solution adopted in the Venice Integrated Facility can definitely be replicated with just as relevant results in new and different situations.

Ladurner’s “waste to energy” is the objective of the Acam RDF plant in La Spezia for the disposal and processing of waste in a large environmental resource.

Ladurner’s “waste to energy” is the objecti-ve of the Acam RDF plant in La Spezia for the disposal and processing of waste in a large environmental resource. The ACAM plant built in La Spezia is a crowning achievement for Ladurner. Inaugurated

on June 13, 2008, the RDF plant combines mecha-nical treatment phases with biological treatment in order to obtain a quality waste fuel (RDF) that can be used as a combustible material in electrical power plants, qualifying as a technical reference standard for similar plants. Ladurner biodrying and RDF production processes boast effectiveness and efficiency resulting from Ladurner’s acquisition of fundamental technical expertise through the con-struction and management of the energy facility in Venice and the continuous R & D in its own tech-

nical division. The La Spezia plant is made up of a central body for the treatment phases surrounded by the transfer, storage and handling zones.The process is divided into three primary stages.Step 1: Reception and pre-treatment of unsor-ted wasteStep 2: Biodrying in Ladurner biocells Inside these concrete structures equipped with hermetically sealed access points on the top, the pre-treated waste is deposited using a bridge cra-ne with a capacity of about 50 t/h. This material is destined for a biological process aimed at transfor-ming it into a dry substance that is no longer pu-trescible, thus preserving the latent energy of the organic carbon. The biocells built by Ladurner in the La Spezia plant allow intensive oxidation due to a complex ventilation system combined with a re-

circulation system that allows a significant decre-ase in the quantity of exhaust air produced. Step 3: after the 7 days needed for waste stabilization have passed, it is transferred to the refinement de-partment where the material with high calorific va-lue is separated from the “screened waste” made up of inert material destined for the dump. The RDF then moves on to the pressing and tying phase for its reduction into bales destined for combustion plants. The Ladurner biostabilization system adop-ted in the La Spezia plant is the ideal completion of the waste treatment cycle. In fact, on one hand it allows the significant reduction of the environmen-tal impact due to delivery to a dump and, on the other hand, recovery of a considerable amount of quality fuel from the waste that can then be used in co-combustion due to its calorific value.

La Spezia, from waste to resource

Bari, a Ladurner plant by daVide FurLan

T his biostabilization plant is capable of grin-ding, sanitizing and reducing the volume of municipal solid waste, making the Bari area self-sufficient and substantially immune

from emergencies due to contingent factors. The work performed at the Amiu Bari company com-plex was inaugurated in March 2010 and is still operating today with the supervision of Ladurner technicians. As usual, the plant design phase was a focal point in which our technical office did their best to accept the requests from the contracting body and the citizens in order to translate them into the best technical solution. The plant design logic therefore wanted and had to find a synthesis between the various needs: maximum plant effi-ciency, operating safety, management ease and environmental sustainability. There are two prima-ry sections of the Bari plant: the part for waste pro-cessing and biostabilization and the one for facility services. The first section includes the machines for the reception and first grinding of the waste,

the biocells for the bio-drying stage and the tran-sport system to the existing grinding/scre-ening plant. The biodrying system conducted in closed cells for 14 days allows for the reduction of humidity and biological oxidation of the organic fraction remaining in the waste. The biodried material is removed with rubber blades and sent to the exi-sting refining shed through conveyor belts which provide for the removal of ferrous materials using a magnet. The approximate 400 tons of unsorted waste that arrive at the plant on a daily basis are about 90% of what the city of Bari produces. This figure, perhaps most of all, speaks volumes on the crucial importance of the work that Ladurner hel-ped create.

The work is an example of virtuous

waste management.

The new plant outside of the city gates that distinguishes the new skyline of the South Tyrol city was recently launched. Ladurner played a leading role in the technological/architectural combination.by burkhard kLoTz

The Bolzano waste-to-energy incinerator

14 MW of high technology

The new Bolzano Sud waste-to-energy incinerator is a reality.The plant was officially “turned on” by the VIPs from the Provin-ce, City of Bolzano and Consortium of Municipalities in 2013. The energy produced by the waste-to-energy incinerator will be able to cover the heating needs of 10 thousand lodgings and will be able to provide the electricity needed to light 20 thou-

sand. The project calls for the maximum thermal exploitation of waste with special attention to maximum energy production and state of the art flue gas purification. The new waste-to-energy incinerator will treat 130,000 t/y of municipal solid waste. The calorific value of the waste is 13 Mj/Kg. Therefore 14.4 MW of electricity will be produced along with 5.9 MW of thermal energy, which will be introduced into the district heating network.

Thanks to the special at-tention paid to the tre-atment of the flue gas, the threshold values will be much lower than the parameters set in Euro-pean and Italian Direc-tives. Special attention was given to the archi-tectural setting of the plant. The entire com-plex is divided into three bodies that adapt to the new Bolzano Sud Skyli-ne, the new city gate. In 2008 the construction of

the plant was awarded to an ATI made up of various companies, including Ladurner, expressed by the President of the consor-tium company that performed the work. The construction site was started in December of 2008 and officially concluded on July 24, 2013. It successfully comple-ted the trial operation period up to March 2014. From the start, the plant was created to use cutting edge technology and in detail, starting from the proces-ses on up to the structural and architectural elements. Ladurner was particularly engaged in the flue gas treatment line that was built to ensure not only compliance with the legal limits but also to stay clearly below them. Completely dry designed and constructed, this abatement system offers a series of advantages for the environment and management since the reagents are reduced, water is not used and load loss is reduced, increasing energy recovery from the flue gas itself. This important reference along with the experience building and managing the CIS waste-to-energy incinerator in Montale (PT) enhances the expertise of the Ladurner Srl Waste-to-energy Division with important skills in the thermal waste treatment industry. In this manner the company further expands its business field and knowledge in the Waste to Energy industry, remaining faithful to the corporate philosophy to always offer the best technology in the waste treatment industry.


We are here

Recently the Ladurner Srl technical office is grappling with a new and fascinating challenge: the design of the new municipal wa-ste treatment plant in the city of Vilnius, capital of Lithuania. Ladurner, in partnership with another South Tyrolean company, Atzwanger, and the local Energesman, was awarded the Euro-pean contract for the design, construction and management of

the work for 20 years. It is a strategic infrastructure financed by the European Community, with a capacity of 277,000 tons/year of Municipal Solid Waste, with the following objectives:- recover materials to be sent to the recycling chain;- produce Fuel from Waste to recover energy;- stabilize the organic residue to reduce the amounts in the dump. To better understand the operation we interviewed Massimo Mapelli (Tech-nical Office Manager) from Ladurner Srl.

Can you describe the process that will take place in this plant?“Double flow technology is used with a few special variants. After the initial bag opener, the waste moves on to the sorting cabin with manual selection for the separation of the first fractions. The residual material is sent to a drum screen with three outputs for subsequent optical material selection, biologi-cal treatment of the residual material and the production of RDF.

What materials are recovered and how? “In the manual selection cabin, glass, paper, cardboard and low density polyethylene (film) are recovered while the ferrous and non-ferrous metals are selected with adequate separators. The optical separators select high quality plastics such as PET and HDPE with good results. Finally a RDF is obtained with energy recovery.”

When is construction expected to be complete?“By September 2015 the plant should be complete as per the contract and we are in an advanced construction phase.”

What machinery and technologies will be found in this plant?“In a consolidated design context, the very driven optical selection stands out along with the ability to ensure the drying of the screened waste in an environment with temperatures that can reach -20°. Plus, the challenge of treating over 270,000 t/y with manual selection was not simply defined in the compromise between the management, investment and size requirements.”

How is a project such as this ma-naged?“The main challenge is the collabora-tion with the local companies and or-ganisation to understand their dyna-mics, legislation and needs. It is also essential to manage to create the right synergy between the different design philosophies with expertise and experience that does not always coincide, transferring it coherently to the final customer. In the end we can say that all of them were enriched.”

And how will the construction site be managed? “We will create a special structure with local staff that will be coordinated and managed by our Project Manager and Supervisors, who will guarantee constant supervision of the construction site for the entire duration of the work and proper connection with the Bolzano operating office, where the Technical Office staff will process any necessary corrections in real time.”

What are the primary differences you found when compared to an Ita-lian project?“Today this type of system is definitely fairly standard and the processes and technology are consolidated. But we were surprised by the request for a such a driven separation of materials starting with unsorted waste, which is not used so much now in Italy.”

So, what do you think of the use of optical separators?“It is a very advanced and functional technology but with significant in-vestment and management costs. Their use is also much more effective on material from a multi-material collection rather than unsorted waste.”

What precautions will you take to limit its environmental impact?“We are taking the traditional precautions; therefore the plant will be equip-ped with biofilters. The entire work area will be enclosed and aspirated with suitable bag filters for dusty environments and a recovery system for all the leachates and wash waters in a tank to send everything to the contractor’s dedicated plants.”

Another European contract for Ladurner.

A new challenge in Lithuaniaby MassiMo MaPeLLi

Ladurner Srl was awarded the contract to build the new Integrated Management Centre for Solid Waste for the entire province of Cluj-Napoca, one of the primary cities in Romania located in Transylvania,

about 440 kilometres northwest of Bucharest. The contract was signed in January 2012 following the European tender, which we entered in November 2011. The work, in which Ladurner will operate in an JV with the other South Tyrolean company, Atzwanger SpA, is in pro-gress.

The plant has a total capacity of 206,000 t/y and is made up of a pre-treatment plant with subsequent biostabilization, a selection plant for the recovery of recyclable elements and a dump for storing the waste.Ladurner will take care of the construction of the mechanical pre-treatment phase and the biological treatment phase of the materials received, which will be stabilized in piles cove-red by transpirable membranes.For Ladurner this is significant proof of its operating structu-res in situations outside of Italy, in order to open up to new markets with its expertise and skills.

Now for the operation, how many people will be involved? “Considering the amounts to be treated, the fact that manual separation will cover all incoming waste, the plant will have 2 shifts per day, 6 days a week and will employ about 50 peo-ple in the complex.Even from this point of view then it is a very complex project in a completely different situation from what we are used to. But we know we are ready not only on the technical level but also on the operational and legislative level.”

So Ladurner, along with the group plans, will start to take its first steps in the inter-national market and will do it right away, starting with a major project in line with the company’s history, proving its construction and organizational capacity.

For Ladurner an experience in Romania

Final testing of the plant that treats 70,000 tons of organic waste and will produce almost 17 million kWh of electricity and 16,000 tons of composted soil conditioner for agriculture.

Albairate in operation

The anaerobic digestion and electrici-ty production plant in Albairate is in complete operation. Located in the Parco Agricolo Sud, in the south west part of the province of Milan, it is a plant for the treatment of munici-

pal organic waste and the generation of renewa-ble energy through the production of biogas and subsequent composting of solid material.It has 2 MW of installed electrical power with an annual production of almost 17 million kWh of electricity, capable of serving over 4,500 do-mestic users/average families and a total power of 2.5 thermal MW, capable of heating over 300 apartments and will treat 70,000 tons of sorted organic waste in the province of Milan, over

60,000 from OFMSW, domestic organic wa-ste. Net of the gaseous material (biogas) that generates electricity, the solid material will be processed for the production of about 16,000 tons of mixed, composted soil conditioner. This compost, a fertilizer for use in full field agricultu-re, is in great demand for organic farming, which will seek to obtain the maximum certifications in the industry.

The construction of the plant, including the de-sign (by Burkhard Klotz), engineering and con-struction is the work of Ladurner Umwelttech-nik, the Ladurner Group industrial company active in the construction and management of environmental and energy plant systems

and the investment will be performed with the project financing formula by Ecoprogetto Mila-no, a partnership between Ladurner Ambiente Spa and La Finanziaria Trentina Spa, through its branch operating in the energy industry, FT Energia Spa, and other Trentino entrepreneurs, partners in LFT. The overall investment in the project financing is over €27 million, €21.5 mil-lion of which is financed by a pool of banks. The financial organization was done by the Cassa di Risparmio di Bolzano, the arranger bank, agent and depository, that involved other regional banks (Banca Popolare dell’Alto Adige, Cassa Centrale Raiffeisen, Casse Raiffeisen di Merano e Terlano and Mediocredito Trentino Alto Adige) and national banks (Banca Popolare and Banca

A TEAM PROJECTLike all major and large infrastructure projects, the Albairate digester is the result of teamwork. The sum of the intuition, will, determination, courage and expertise of many people who, in their own way, contri-buted to make it “a team project.”From the political/administrative point of view, we would first like to remember the late Luigi Masperi who, as mayor of Albairate, pro-moted the composting plant along with the late Engineer Josef La-durner. The two of them were responsible for its origin. Then there is former mayor Luigi Alberto Tarantola who, with his council, and most notably Giovanni Pioltini, the current Mayor, believed in the re-launching of the plant with the addition of the anaerobic section and energy production and with major benefits for the city budget. All was done under the watchful and alert eye of the Milan provincial administration through its various officials.

On the specifically technical side, both the composting and digestion design was done by engineer Burkhard Klotz, CEO of Ladurner Srl, with the support of the technical office and specifically Massimo Ma-pelli and his technical staff. As for construction, we must thank engi-neer Claudio Biondaro, Operating Director of Ladurner Srl, surveyor Fiorenzo Garda, Job and Construction Site Manager and engineer Carlo Guidetti, Work Director, who kept the project on course regar-ding time and quality choices.

But, as we know, work must be financed and from this point of view, Andrea Silvestri, CEO of Ladurner Ambiente and Massimo Fedrizzi, Director of Finanziaria Trentina played important roles with the col-laboration of Roberto Marconi, the project’s “metronome” from the administrative and financial point of view. And finally, in order to con-struct the project the political and administrative conditions and au-thorizations must be produced, which we owe to the coordination of Bruno Abram, CEO of the project company, with technical/regulatory collaboration from Dr. Francesco Codato, Technical Manager of the Plant and Operational Technician Davide Pavan, Industrial Manage-ment Supervisor.

The company signed a contract to operate the activity for 25 years starting from the final testing of the new plant.In fact, it is the first digestion plant for waste treatment in the province of Milan.The company’s Board of Directors, headed by President Diego Mosna (who has always been involved in environmental issues and with the Dia-tec Group in the “Cittadella dell’Energia” project at the former paper mill in Tirano, Valtellina), along with CEO Bruno Abram, Ladurner Group Ma-nager and Council Member Vittorio Marangoni, an engineer specializing in the industry. Ecoprogetto Milan is a decisive step forward towards the production of renewable energy through the construction of a plant with the most reliable and consolidated technology on the market.

This was possible thanks to the Ladurner Ambiente Group that made its expertise available and that will take care of the operational industrial management and strategic management of the entire system as well as FT Energia and a group of Trentino entrepreneurs who recognized the quality of the initiative and supported it financially.

Waste sorting solutions for hotels

Grand finale at Tortona!

One of the new waste communication projects by Ladurner Energy - Idecom division called ECOmò. The only one of its kind, it is a modern, practical and 100% sustainable solution to bring sorted waste inside the hotel, to the floors and at the service of all guests. This was an idea brought about by a specific request from Conai.

In Italy it is made of FSC certified, environmentally-friendly cardboard. It has convenient cases lined with drip-free material and ideal for col-lection of the various types of recyclable waste. It comes with an open space for newspapers to allow for reuse and exchange before they are thrown away. Located in the hall or near the corridors, it offers the guests an integrative service, showing the Hotel’s concern for the en-vironment. ECOmò is a concrete operation for a Green Hotel, a calling card for customers and a real possibility for the partners in the initiative to enter the special tourist context.A company with environmental certification that decides to use Ecomò as in incentive for its customers can show that it offers a completely recyclable product and thus pays attention to its entire life cycle according to the adopted environmental policy principles. ECOmò is more than a design object for waste collection. It is a complete communication project that, by itself, transmits sustainability and a different approach to these themes even in Hotel rooms where they are often not tackled. In fact, it will be supported with informational cards to be left inside the rooms to promote the use of ECOmò and thus proper waste sorting. The pilot project was created in Giudicarie (TN), which in-cludes major tourist areas such as Madonna di Campiglio, Comano Terme and Pinzolo and will be financed by CONAI with the participation of Tetra Pak Italia.

In honour and in connection with EXPO 2015, Ladurner will organize the open day event at the anaerobic digestion plant in Tortona/Alessandria.

In 2014 Rem-Tec was awarded the contract for environmental rehabilita-tion of the non-hazardous waste dump in Malagnino, Cremona.This is the final coverage of the Municipal Solid Waste dump created and managed by A.E.M Gestioni Srl, a Cremona company. With a high qua-lity proposal, the association of companies led by Rem-Tec (a Ladurner group subsidiary) was able to win a €3.8 million contract, beating out 15

other groups from throughout the country. The primary elements contribu-ting to the quality of the work performed are: use of cutting edge methods from the technological point of view, certified and tested materials based on the specific conditions along with experience in the environmental sector by the staff employed by the executing companies.

The work, in an advanced state of execution, provides for covering the landfill, closed to transfers since August 2011, with a waterproofing packa-ge consisting of a biogas drainage layer, low permeability mineral coating, water drainage layer, non-woven fabrics for separation, layer of topsoil and a local polyethylene geomembrane with high mechanical properties. Special attention was paid to the technical characteristics of the materials used, the precision and quality in executing the processes and almost continuous checking of the materials used.

Checking the covering package is, in fact, the best guarantee for quality of a dump covering over time, with direct repercussions on the environmental impact in post-closure and on the management balance sheet. The techni-cal objectives are continuously checked and verified through a strict quality control plan and monitored by the client and supervisory bodies. Rem-Tec, based on the Ladurner group’s experience in the construction and mana-gement of dumps and municipal solid waste treatment plants, is able to

identify the best technical solutions for covering dumps, taking into account the specific characteristics of the site and its waste and especially the future impact on its management based on the choices that are made.

Sealing the body of the dump has been improved using materials with per-meability coefficients in an order of magnitude that is less than those set forth in the project. During the executive phase, precautions were introdu-ced in the processing cycle that allowed for a reduction in the leachate pro-duced during the work. The work will finish at the end of spring 2015.

The Venice Integrated Project, the plant that will save a unique natural habitat

S.O.S.

The goal is to restore and protect the waters of the Venice lagoon and the watershed that surrounds its splen-dour, rebalancing an

ecosystem long-threatened by the coexistence of major industrial and civil elements.

With this purpose, the Veneto Region has advanced the Venice Integrated Project through project financing, that consists partly of public capital and partly of private capital, for the design, development and completion of work that will enable the transformation of the Venice purification plant into a multipurpose treatment centre for civil liquid waste, the storm water from Mestre, Marghera, Porto Marghera and the Mirese, industrial liquid waste from Porto Marghera and the resulting leachate from landfills in the province of Venice.

Ladurner Srl was responsible for implementing the entire MBR (membrane bioreactor) section for the treatment of the leachate from all dumps in the province of Venice and will be able to treat about 500 m3/h of waste water.The work consists of a purification system serving the industries in the port of Marghera, to which the purified elements will be destined for technical use. The total amount of purified water will also include the finishing of the waste water from the existing civil purifier for about 16,000m3/h of waste water and about 6000m3/h of various industrial waste water. The project is supplemented by the natural phytopurification for industrial reuse, the sa-fety of the Venice lagoon with the dispersion of the purified waste into the

sea through the sea pipeline that is over 20 km long with 10 km crossing the lagoon and 10 km for discharge into the sea.

The great operation coordination work for purification of the waste water and regeneration of used water will bring concrete benefits at an envi-ronmental level, with the return to the lagoon of animal species that were disappearing. In the future the area will become a natural park and will be a green lung between inland Venice and the lagoon.

The project driven by Ladurner will bring light to the ships in the Malamocco Canal

A lighted pathway in VENICE

Technological challenge in the lagoon. Ship access to the commercial port of Porto Marghera is through the Mala-mocco Canal, site of the Venice lago-on where the ships are directed using the aforementioned “lighted pathway”

that marks the canal since 1989, allowing ships access to the port keeping them from going into the shallows and allowing landing even in the most extreme conditions like heavy winter fog. The “lighted pathway” extends from the port of Marghera to the open sea, for an overall length of about 8 km and includes 345 lights installed on steel rods driven into the bottom of the lagoon, with an average distance of 80 ml.

In the old version, the lights were made up of two low pressure sodium vapour bulbs with 36Wp each attached to the Enel mains and the system was supplied by electrical cables installed on the bottom of the lagoon. Due to their vulnerability ba-sed on the age of the system and to accidental and malicious events, the system efficiency and availa-bility is affected, compromising its functionality in long sections of the lighted pathway.

Project Financing driven by the project company, Lighting Venice Port Srl, whose major shareholder (85%) is the Ladurner group, will allow the mo-dernization of the “lighted pathway” through the installation of excellent technology that introdu-

ces innovations through sophisticated solutions that have been highly customized for the specific project. They were created through an enduring research and development process driven by La-durner Energy in collaboration with major Chinese company specializing in LED lighting systems and cutting edge technology in photovoltaic energy. The project will allow the substitution of the cur-rent technology with the new system in a period of 12 months. The new system will be highly efficient in terms of electrical consumption (energy needs will be reduced by 84% and entirely covered by photovoltaic production) and in terms of system efficiency which will be controlled remotely and based on special LED bulbs that, with only 3Wp of power each, will be able to improve the functio-nality and availability of the previous system. The “lighted pathway” will then be transformed from a configuration based on poles connected with elec-trical cables to a new configuration with “stand alone” poles having two LED lamps of 3Wp each, four custom-sized photovoltaic panels to reduce visual impact and specifically designed to ensure high electrical production efficiency and operating compatibility over time in a saline environment.

Four batteries will be housed inside a pole and an interconnecting box that is the technological core of the system as it holds a sophisticated electronic system capable of managing the battery charge, turning the lights on and off and data transmis-sion that will allow remote control of the “lighted pathway” functionality and will allow quick recep-tion of any system alerts to ensure timely mainte-nance, thus ensuring the availability and use of the system.A special innovation was introduced with the de-velopment of the LED lamps that, besides using little energy, also eliminate light pollution as they were designed to concentrate the light in the visual angle needed by the ships to follow the direction of the lighted pathway, eliminating all light emissions in other directions.

This result ensures and improves system functio-nality while paying special attention to reducing the lighted impact of the system itself where it is not functionally useful. Finally, the lamps are equipped

with special Amber LEDs produced specifically for Venice by the American company CREE, world le-ader in LED production. This colour temperature has an increased capacity for penetrating the thick fog, making them visible in the most extreme con-ditions. These special Amber LEDs also eliminate the emission of the typical blue light of LED lamps, which is also considered to be a source of light pol-lution. From the engineering and functional point of view the Venice Lighted Pathway project is a suc-cess for the Ladurner group. It was able to drive and win this technological challenge due to group’s great engineering skills driven by engineer Loris To-gnoni, Technical Director of Ladurner Energy and the ability to guide the development team, united partners and international skills to ensure the most innovative solutions to a project that has unique characteristics.
