Agri-business masters circular economy approach using biogas

A circular economy approach in which vegetable residues are turned into biogas covers up to 40% of the energy used by frozen vegetables, herbs, and fruit producer Ardo in Ardooie, Belgium. Over 70,000 tons (t) of vegetable by-products, 8,000t of maize, and wastewater are used to produce 24,000MW/h per year in a process that also yields organic fertilizer and clear water. No manure or animal by-products are used at the two Digrom energy plants in Ardooie.
