A Defra strategy is now in place hopes to see a large increase in the number of anaerobic digesters constructed in England and Wales over the coming decade with a target of 1,000 new digesters to be built by 2015. The feedstock for these new digesters will be predominantly food waste and the organic fraction of municipal waste, currently sent to landfill, together with farmyard manures that are spread to land. Financial incentives to encourage the take-up of anaerobic digestion are provided by the government in the form of Renewable Obligation Certificates (ROC’s), Feed in tariffs (FITs) and Renewable Heat Incentives (RHI). In addition to this, digestion facilities will derive income from gate fees for the waste and from the energy produced in the form of methane gas. However for many facilities it is the fate of the digestate, which is an end-product of the digestion process, that will determine the payback period and in many cases dictate the overall financial viability of the scheme.
