Anaerobic Digestion UK Including Regulations and Objectives

Regulatory Requirements for UK On-Farm AD Plant Installations

The following applies to United Kingdom regulatory requirements.

Always check your local requirements with your local authority and regulator as appropriate. These regulations are subject to constant change. No responsibility is accepted for the correctness of this information. Always check the source documents before taking any action.

Anaerobic Digestion UK – Planning Consent

Planning consent is likely to be required for all anaerobic digestion plant installations, and it is advisable to consult with your local planning department at an early stage.

The Town and Country Planning Regulations will apply much as they would for any industrial plant. The Centralised Anaerobic Digestion (CAD) plant applications being for larger-sized installations than On-farm Plants, will have to provide more detailed information than will be required for smaller on-farm plant applications.

The nationwide forecast for Anaerobic Digestion UK is uncertain.The applicant will be required to provide detailed justification that community (centralised) anaerobic digestion schemes are suitable for the proposed location, with impact assessment information based upon a detailed understanding of the controls on emissions which will be provided for the plant.

The Local Authority Planning Department will determine the application and consultation with local residents and neighbours with education and awareness aimed at planning officers and locals can be highly beneficial.

The Kelly Review has been examining the case for making the planning system more effective towards the delivery of expansion of the nation’s waste management facilities. It is not known at the time of writing what the outcome of this review will be.

However, unless and until there are changes, the requirements should be considered to be onerous for Anaerobic digestion plant applicants.

Environmental Permitting to Operate Anaerobic Digestion UK Plants

Centralised anaerobic digestion schemes are subject to the EU Pollution Prevention and Control (PPC) Regulations. This was originally known as PPC permitting or IPPC permitting.

In addition, in some circumstances, Waste Management Licences have also historically also applied to Anaerobic Digesters.

To simplify environmental regulation the Environment Agency, England and Wales, now regulates both sets of Regulations under the “Environmental Permitting” system.

Those applying for an Environmental Permit will, once successful, be in possession of a “permit to operate” which will cover all the separate primary instruments which apply.

Within the permit, the regulator (EA) will set a number of operational conditions. These conditions will be based on the use of the Best Available Techniques, referred to usually as just “BAT”.

The PPC permit conditions will also usually put a responsibility on the developer to take action to:-

  • ensure that energy is used efficiently,
  • avoid or minimise waste and limit emissions,
  • prevent accidents and limit their consequences
  • provide continuous improvement as the available technology improves with time.

AD plant technologies are normally seen as BAT complaint processes, however, each plant will need to be judged individually and within the setting of the local environmental conditions.

The Animal By-Product Order (ABPO) as Applied to Anaerobic Digestion UK Facilities

The EU Animal By-Products Regulations (ABPR) have strengthened the regulations that govern the processing and disposal of animal by-products.

These ABP regulations require the processing of all food wastes to strict requirements designed to prevent the future spread of infections which might otherwise survive waste processing methods such as Anaerobic Digestion to threaten re-infection of more livestock.

There will be strong points to make in favour of anaerobic biological treatment schemes which are well suited to the required degree of pasteurisation required of all the material processed.

The ABPR puts stringent controls on the process requirements, including:

  • Time and minimum temperature and residence time at the required elevated temperature.
  • Strict segregation of clean and dirty sides of the process and facilities for vehicle washing
  • Two-stage process – under certain conditions.

The Regulation EC 1774/2002 (the ‘EU Animal By-Products Regulation’) has been applied since 1 May 2003.

Specifically, the ABPR permits AD plants to treat food/catering waste as well as low-risk animal by-products as long as they are subjected to an elevated temperature of at least 70°C for 1 hour in a closed system.

Anaerobic Digestion UK Project Objectives

Anaerobic digestion in the UK has been growing rapidly since the middle of the 2010s, and a highly diverse set of project drivers has created a number of specific markets, in which the following objectives have been identified.
The following list of Anaerobic Treatment objectives is not necessarily comprehensive is constantly growing and may be extended further by the next time you visit.
 i. To provide a farm waste regulations compliant, sustainable, and cost-effective method of disposal of organic farm wastes (in the UK, and many other EU Countries, the national waste management regulations have recently been extended to cover farm waste so this objective is.
ii. Ditto, for Municipal Solid Waste, with compliance in accordance with Waste Management Regulations and PPC Permit requirements, and other organic wastes including pre-sorted or kerbside collected and segregated MSW
iii. To treat, and clean source-separated organic waste from households, restaurants and other enterprises, in an environmentally correct manner

iv. To provide a sustainable and cost-effective method of disposing of ABPR waste materials

v. To reduce carbon emissions, and carbon levies payable associated with a business

vi. To establish a sustainable circulation of plant nutrients and organic material between the community and the agricultural sector in such as way that the use of the residual is optimised

vii. To provide a cost-effective system for the production of biogas vehicle fuel

viii. To extract biogas and plant nutrients from ley crops, thus assisting the UK government in achieving targets in achieving the recently increased non-renewable energy production targets

ix. To contribute to an environmentally adapted and sustainable form of farming

x. To provide opportunities for studies regarding the long-term effects of cultivation through the recycling of organic matter involving ley crops and fertilising with the liquid and fibrous AD Plant effluent (digestion residuals)

xi. To provide opportunities for the reduction or elimination of the use of artificial fertiliser (ie to promote organic farming)

xii. To provide a local centre of excellence in these technologies for wider dissemination into the community to enable the county to fully participate or even lead in the adoption of these clean technologies and to generate jobs, new businesses, and wealth locally from the expertise created

xiii. To extract and use high-grade bio-energy from waste and normal farm crops, with no net contribution to the atmosphere

xiv. To promote and develop high-efficiency energy processes

xv. To remove odours generated from present systems

xvi. To reduce the risk of water pollution from current practices, and generally reduce emissions of enteric organisms into watercourses. (Back in the 1990s Enviros and the Scottish government's Executive work resulted in the installation of 8 No. on-farm AD Digestors in the Dumfries and Galloway region was for this purpose. These AD plants were for farm wastes only. https://www.gov.uk/government/publications/sr2021-no-8-on-farm-anaerobic-digestion-facility-using-farm-wastes-only-including-use-of-the-resultant-biogas-installations/sr2021-no-8-on-farm-anaerobic-digestion-facility-using-farm-wastes-only-including-use-of-the-resultant-biogas-installations)

xvii. To reduce materials sent to landfill/assist the government in complying with the EU landfill directive’s targets for the diversion of waste (especially organic) away from landfill

xviii. To reduce overall methane emissions produced by livestock due to methane emitted by livestock digestion. (In California this is seen as a high priority, and the proportion of total national methane generated by livestock is surprisingly high.)

Concluding our Article About Anaerobic Digestion UK

In conclusion, on-farm anaerobic digestion plants have gained popularity in recent years due to their environmental and economic benefits. However, there are regulatory requirements that must be met for these installations to operate legally and safely in the UK.

From obtaining necessary permits to ensuring compliance with health and safety regulations, on-farm AD plant operators must follow a set of guidelines to avoid potential penalties or shutdowns.

By understanding and adhering to these regulatory requirements, on-farm AD plant operators can contribute to a more sustainable future while also protecting their investment and reputation.

    I did only stumble upon this, but I’ve found it positively helpful and it has aided me in assessing farm business for suitability. Of course, there is a whole new layer of regs. not mentioned here, which are the requirements for receiving payments of the various government incentives. No worry, this internet info still does a great job.
