Accelerated biogas production without leachate recycle

摘要

The economics of biogas production remain marginal, even on 'free' substrates such as wastes. However, new insights into the fundamental processes of solid-state digestion promise a much aster and more predictable process. This holds the future prospector of profitable biogas production form anaerobic composters fed with a range of solid substrates, including food industry wastes and biomass crops. A novel process model proposes that reaction occurs at a well-defined but mobile interface Between raw and depleted wastes, forming the boundary of an independent expanding micro- Reactor.
