UK Biomethane Sites

Recognised role to playAmber Rudd MP:The highest potential for additional renewable heat is from bio-methane injection into the gas grid, which could deliver up to 6TWh (or 0.4%-points) by 2020. However a significant proportion of this (up to 4TWh) is already included in the proposals for continuing support for renewable heat post 2015/16.

10 The Voice of the Networks

Energy Networks Association


• As the representative body for the UK’s gas and electricity networks, Energy Networks Association is well placed to analyse the whole energy system without bias towards any energy source.

• Any holistic consideration demonstrates clearly that our gas networks will have a vital role to play in the coming years; not just in an affordable progression to a low carbon economy, but also as a long term part of a sustainable energy mix through the injection of green gas into the grid.

Security


The Gas Networks

Customer Choice - Gas is the fuel choice for UK consumers, meeting the heating needs of almost 85% of domestic properties

and the cooking needs of around 50% residential and service sector buildings.

Security – Over 80% of peak energy usage is currently derived from gas. Without gas and the gas networks there is simply not enough energy for the UK to function or the means to transport

that energy at peak periods.

Sustainability – Peak gas and electricity demand is 25 times higher than existing low carbon capacity.

Affordability - Heating your home by gas is around 3 times cheaper than using electricity and saves consumers over £400 per

annum compared to alternatives.

• Direct support for biomethane injection is principally through the non-domestic RHI

• However complimentary support for electricity generation through FiTs is often seen as crucial for biomethane schemes

• Autumn ‘15 review of FiT Scheme– Removal of right of generators to claim

generation tariff on scheme extensions– Introduction of quarterly deployment caps

for technologies

• Spring ‘16 review of FiT support for ADand m-CHP – Currently out to consultation– Proposes changes to AD generation

tariffs from January 2017– Introduction of sustainability criteria

and feedstock restrictions• Focus support on biogas from waste

or residues

Fiscal incentives - FiTs


• Sustainability criteria introduced in October 2015– GHG and land criteria– Requirement for quarterly/annual reporting

• Budget 2016 confirmed continuation of reformed RHI scheme through to 2020/21

• Spring ’16 consultation on scheme – Currently awaiting Government response– Proposes budget caps for biogas/biomethane allocations based on annual

deployment for biomethane of 20 schemes/year by 2021– Possible resetting of biomethane tariffs– Introduction of feedstock restrictions

• Focus support on biomethane from waste-based feedstocks– Introduction of tariff guarantees

Fiscal Incentives - RHI


• Support continuing through FiTs and RHI but with changes– Details of many changes still to be confirmed

• Changes suggest:– Continuing support for biomethane injection– Shift away from the use of biogas to generate electricity at large-scale– Focus on the use of waste-based feedstocks for AD and biomethane

production– Further strengthening of the budget management mechanisms to avoid future

Biomethane End-of-waste Quality Protocol

Typical NEA conditions


• Siloxanes are widely used within household products. Hence their presence within biogas from landfills and waste water treatment plants has been known for some time

• However, polydimethylsiloxane (dimethicone) is used in food production as a anti-foaming agent (E900), meaning that it may also appear in food waste

• Various standalone technologies exist for siloxane removal but the feedstock risk needs to be assessed and managed

• Selected upgrade technology will influence siloxane content of the biomethane

• Volatile compounds containing Silicon, Oxygen and Methane groups

• Do not occur in natural gas

• Oxidises to produce microcrystalline silicon dioxide (silica)– Highly abrasive– Thermal and electrical insulator

• Therefore, presence of siloxanes in biomethane not desirable for many gas appliances

Siloxanes


• Fiscal incentives remain but with greater focus on the future production of biomethane from wastes and residues

• Achievement of biomethane quality criteria can only be expected to gain importance as overall injection capacity increases

• Risks to biomethane quality associated with the use of new feedstocks need to be assessed and managed

Feedstock and feedstock security drives your business case


Simple feedstock sourcing concepts = key success factor

Guiding principles:

1. Collect “all” organics within the plant’s vicinity

=> why driving far for “cherry picking”?

2. Collect it mixed / commingled(as feasible)

=> why separate collection logistics and why bother people too much?

Proven technologies and capable contractors enables your business case


Sound technology & turn-key contract = risk insurance

Guiding principles:

1. Use robust technology, proven in many references

=> it’s not (only) the first 3-5 years, but the remaining 15 which matter…

2. Get technology in one package from EPC supplier

=> unless you’re able to manage interfaces better/cheaper

=> keep the “bankability” of your project in mind

Micro- and macro-economic aspects are in favour of BioCNG


Micro-economicsHigher system efficiency than CHP (typically heat is not used efficiently)

Economically attractive: lower gate fee- compared to CHP (especially if BioCNG is tax exempted)- due to commingled organics collection

Macro-economicsA real alternative for transport / fossil fuels

Municipality stays in charge: “local waste to locally produced fuel and fertilizer”

Reduction of local air pollutants and greenhouse gas emissions

Local job creation

Residents develop local ownership and “feel good”


«I was impressed by the plant, how everything runs fully automated. I was

also surprised how clean the whole plant is. I mean, it is a waste plant and

one imagines everything quite differently – it is really high-tech here.»

Visitor statements after the “experience biogas” day,

Kompogas plant Zurich/Switzerland, 18 April 2016

«I knew already a few things about biogas, but it is actually

my biowaste which is processed here. I find it terrific that these natural resources are used further, rather than simply being incinerated.»

«Biogas is a good thing – one uses a resource which is

regional and available daily»

UK Biomethane Sites

Recognised role to playAmber Rudd MP:The highest potential for additional renewable heat is from bio-methane injection into the gas grid, which could deliver up to 6TWh (or 0.4%-points) by 2020. However a significant proportion of this (up to 4TWh) is already included in the proposals for continuing support for renewable heat post 2015/16.

eligibility

Reset tariff levels

• ADBA response strongly supported need to reset tariffs• Consultation referred to biomethane; ADBA made the case for re-setting biogas heat tariffs too

Feedstock restrictions• Consultation proposed either stopping paying for biogas from crops, or restricting payment to up to 50% of production from any one site• ADBA response supported latter but raised practical issues and problems with consultation assumptions• DECC appear to have a strong desire to go beyond existing sustainability requirements, but final details difficult to predict

Caps and guarantees• RHI scheme already ‘capped’ to prevent total deployment breaching budget• Operation of caps to be set by consultation response, balancing early notification against risk of over/under spend• Tariff guaranteed pre-accreditation proposed in mitigation• ADBA response strongly supported; suggested improvements in mechanism

Heat eligibility

• ADBA response showcased examples where digestate drying is providing clear benefits• Can DECC differentiate between what they want to support and what they do not?

WRAP’s position:

• The provision of caddy liners to householders is increases yields of household food waste collected when provided as part of a ‘package’ of measures;

• The type of liner whether PE or compostable does not effect the amount of food waste collected;

• Food waste collectors should liaise with their food waste processor to ensure liner is compatible with the processing facility.

Bioplastics – Should we Use Bioplastics in Food Waste Collection?

Götz Ahrens, European Bioplastics, 7th July 2016

162

• Foundation of IBAW• Biodegradable polymers• Germany-focused

• Change of name to European Bioplastics• Bioplastics (biodegradable, bio-based, or both)• Network for information & political representation

• Networking on EU & Member State level• Global network, convenor of the Bioplastics Organisations Network (BON) Europe

European Bioplastics: 20 years of bioplastics expertise

• European Bioplastics represents the bioplastics industry in Europe

• Its members are companies from the entire bioplastics value chain, from feedstock production, to chemical and plastic sectors, to industrial users, as well as brand owners and recycling companies

163

European Bioplastics‘ definition of bioplastics

BIOPLASTICS are

bio-basede.g. bio-PE

biodegradablee.g. PBAT

or bothe.g. starch blends

So-called „oxo-degradable“ plastics and enzyme-mediated degradation plastics are not bioplastics. These materials do not fulfull any clear pass/fail criteria for biodegradation, and they do not adhere to

accepted norms such as EN 13432.

164

1. Separate collection is much more practical, hygienic, and odourless with compostable bags, raising acceptance and awareness levels

2. Compostable biowaste bags significantly increase separately collected biowaste, resulting in higher biogas and compost yields in AD and composting

3. Their use reduces the quantity of misthrows / the amount of PE bags in the collected biowaste

4. Less biowaste going into incineration and landfill (and consequently less escaping methane)

5. Source-separated biowaste collection diverts biowaste from residual waste streams, making them less contaminated

6. Most biodegradable bags are wholly or partly biobased and reduce our reliance on finite fossil resources

7. Made from materials rich in carbon and low in nitrogen, which has a positive influence on the carbon/nitrogen ratio in the compost

The benefits of compostable biowaste collection bags:

The Seedling® logo helps to identify industrially compostable bags.

165

• Compostable dual-use bags can replace conventional plastic shopping bags AND function as biowaste bags, increasing collection rates

• Since compostable bags can greatly increase the quantity of collected biowaste, organic recyclers benefit from higher biogas and compost yields

• Compostable bags are a prime example of a useful bioplastics application engineered with the circular economy in mind

Should We Use Bio-Bags in Food Waste Collections?

Emma TilbrookSenior Consultant Eunomia Research & Consulting Ltd

7th July 2016

• What is the business case for investing in bio-bags for food waste collections?

“Will they make a difference to my food waste yields?”

Introduction

“How can I justify the additional costs”

“How will I convince my finance team of the need to invest in liners”

Question 1: The Impact on Yields

Free Liners• Delivered regularly

to households• Delivered on

demand • Pick up from

offices etc.

No Liners• Initial roll provided• Purchased by

householders • Not used by

householders

Question 1: The Impact on Yields

• WRAP trial data demonstrates that the provision of liners does increase food yields;

• However this is relative – if you service already performs well, will that impact be significant enough to warrant investment?

Question 2: Justification of Cost

Approx 0.12 kg/hhd/wk Approx 0.5 kg/hhd/wk

Question 3: Guaranteeing Investment

• Model the potential impacts using referenceable data;

• Prove the case; • Understand what you are investing in;

and• Demonstrate the ongoing impact.

Question 3: Guaranteeing Investment

Investment Case

Model the Impacts

Prove the Case

Understand the Extent of Investment

Demonstrate the Impact

Conclusions

• There is a business case for investing in liners if you can uplift your food waste yields;

• Work collaboratively with your disposal partners to understand if there are more cost effective liner options; and

• Build a strong business case for investment.

What is Missing?

Moving up the waste hierarchy by reducing the strain on fossil resources and virgin biomass through converting waste to fuels and chemicals (the circular economy)

Robust processes needed to deal with heterogeneous urban wastes producing drop-in intermediates for uptake by the chemical industry

Scale-up industrial biotechnologies part of an integrated supply chain (the integrated biorefinery) to overcome barriers to commercialisation

Why take an integrated biotechnological approach?

• Integration and Optimisation• Changeable process depending on output needs:

energy, type of energy or products

• Value creation• 10 year plan – no gate fees

• Building of local value chains• Local target products for regional needs

• Products not produced at commodity volumes• Diverse ‘niche’ product portfolio required
