900kW waste heat used with Dryer at Lincolnshire

The brothers Roe from Lincolnshire decided to cooperate with Dorset to improve the environment by using waste heat to dry liquid digestate at their biogas plant. The system also includes a three step air cleaning system to avoid any smell, dust and ammonia emissions.

To dry liquid digestate directly from the digester, the dryer will be equipped with a back mixing system. In total 900 kW of heat from the CHP can be put to good use.

The end product is a granulate that can be easily spread and and contains high value on NPK.

Delivery in January 2016.
