On-Farm AD Fund
The On-Farm Anaerobic Digestion Fund has been developed to help farmers in England get financial support to build small-scale AD plants on their farms. See http://www.wrap.org.uk/node/16778 for further details, and a grant application form.
The scheme is split into two parts:
The first part is a business plan grant up to £10,000 to investigate the environmental and economic potential of building an AD plant on the farm.
The second part is a capital loan up to £400,000 (or a maximum of 50% of the project cost). This is available for AD plants producing up to 250kW of power.
The funding is available in England only, however if you are a farmer in another nation resources have been produced to help you through the process of feasibility and business planning.
