Mono-digestion in the food industry

In Bury St. Edmunds (Suffolk), United Kingdom Agraferm built a biogas plant for British Sugar, the leading sugar producer in Britain and a company of the AB Group. This plant is compact but at the same time highly efficient and powerful. It is designed and realised with the smallest footprint at highest industrial standards. A special feature of this plant design is the liquid feeding. Large quantities of pressed sugar beet pulp and beet waste are fed according to the innovative Agraferm liquid feeding method without using any manure or process water.

The resulting waste heat is used to thicken the digestate through a dryer system. Environment-friendly design thereby reducing transport and utilization of heat and electricity on site.

Safely operated at dry matter contents of 10 – 12 % in a CSTR-digester with a height/ diameter ratio of > 1/3. The tank sizes were designed such that the particularities of mono-digestion such as increased foaming can be well managed.
