Wet Anaerobic Digestion

When dry matter (DM) concentrations are below 15% the process is described as wet. A wet digester will typically process a slurry of around 10% DM which has the consistency of thin soup and must be constantly stirred to prevent suspended solids from precipitating. Stirring is usually either mechanical in which case a rotating paddle is the preferred method, or gas, in which case the biogas given off is redirected through the substrate to ensure stirring. Wet digesters are nearly always constant flow digesters.

Wet digesters are ideally suited to the processing of low DM feedstock such as farm slurries and source separated food wastes.


Zero Waste

Philosophy that encourages the redesign of resource life cycles so that all products are reused. No trash sent to landfills or incinerators
