HoSt built a co-digestion plant at Biogas Bree. Unique about this system is that the vegetable and animal material is digested and drained in seperate lines. In Belgium, the digestate from the vegetable digesters does not have to be sold as animal manure, which makes it a valuable product to sell.
The vegetable products are converted in two highly efficient two-stage digesters. The solid fraction of the vegetable digesters is being digested in a third digester along with the animal products in order to achieve the highest possible returns. The digestate from the animal digester is dried in combination with the solid fraction of the vegetable digesters with waste heat from the CHPs.
Manure, agricultural products and waste streams are used for generating renewable energy and heat. The capacity of the installation is 45,000 tonnes/year and the installation produces 2.5 MWe of renewable electricity.
