• Energy needs are growing worlwide.
• The dependence on fossil fuels will remain high.
• It is anticipated a growing demand for renewable energy, particulary electricity generators.
Electricity needs and sources
Types of Biomass
Energy crops
Forest biomass
Agricultural waste
Biomass is a renewable source of energy, practically inexhaustible.
Preparation of biomass
Moisture• Maximum allowed
moisture 20%
Crushing• Splinter size 5 cm• Not necessary pelletizing
Storage SystemPackaging•Dimensions: 0.9 m high, 1.2 m wide and 2.5 m long.•The bales are stacked one above another, forming blocks of 36 bales. •Indoor or outdoor storage.
In cone•Dimensions: 8 m high x 6 m diameter.•Outdoor storage to promote drying of the material.
2. Gasification
Advantages of gasification
Elimination of almost all of the incoming waste
• The resultant ashes are inert• Of minimum volume• They are easy to recycle or
treat. Possibility to recover heavy metals
Reduction gas emissions
• A 40% CO2 and 100% CH4• High filtration efficiency: avoid
the emission of toxic gases• SO2, SO3 and NOx
(promoters of acid rain)• Dioxins and furans
(carcinogens)
High efficienc
y and
profitability
• Lower cost per Kwh generated
Abundance of fuel•No dependence on foreign•Usable in separate areas
To eliminate waste To generate electricity
Problems of uncontrolled biomass burning
• Smoke production with fine organic particles with high concentrations of soot.
• Emissions of CO by bad combustion.
Advantages of the gasification front of the incineration
• In gasification, emissions of hazardous compounds (dioxins and furans) are 1.000 items smaller.
• The energy efficiency is about 32% (front of 22% of incineration with Rankine cycle)
• It generates 40% of CO2 less per kWh produced.
• Gasification allows smaller plants (from 0,5 MW)
3. GreenE plants
Why GreenE?
Strong•Able to waste to energy all types of biomass, independently of its level of impurities
Power generation• Syngas generation can be
transformed into electricity and heat
Profitability• Maximum efficiency of the process• Minimum investment per MW
installed.• Profitable plants from 0,5 MW
Experience• 8 years of development. 2
pilot plants.Proprietary technology and manufacturing.
Service• Full range of services to ensure the
implementation and operation of the plant.
Modular plants• Easy installation• Low cost of installation• Easy transport
GreenE technology: gasification in rotary kilnCan be used for
any type of organic waste
Ability to process waste
with lots of ashes
High power generation
High quality and
durability
Dry filters: will not generate
polluting waters
Advanced system for
removing tars

waste
Coal and wood
GreenE gasification plants adapt to any type of organic solid fuel.
They can work with hard bark species such as poplar or onocotiledoneas with high silicon content, as the thistle.
Comparison with other gasification technologies
“Down draft”
•Only valid for very pure biomass.•Pelletizing biomass is needed.•Ash content is limited to ≤ 2,5%
“Fluidized bed”
•High cost of operation and maintenance.•Pelletizing biomass is needed.•Ash content is limited to ≤ 2,5%

Power Generation
Generator
• Gas Engine "Otto cycle", four-stroke, with turbocharged of the mixing and cooling of it, working on the principle of “lean-burn”, “LEANOX”.
• Electric generator driven by the engine
• Electrical efficiency of 36%
