NEW INTEGRATED DESIGN OF DRY ANAEROBIC DIGESTION WITH COMPOSTING RESULTING IN 5 PRODUCTS: GREEN GAS, CO2 , HEAT,
CONDENSATE WATER AND COMPOST
Public awareness and growing requirements to sustainability lead to a transition in the treatment of municipal biowaste from composting to anaerobic digestion, followed by composting. Concepts which include digestion are ecological superior but often complex and expensive.
We designed a new integrated design with the aim to:
1.Lower costs2.Simplify technology and make it more straight forward3.Increase sustainability re-using heat, water & compost from composting,
together with green gas and CO2 from digestion; 5 products in total.
