Texas A&M Study indicates that biochar could significantly improve anaerobic digester performance

By Bioenergy Insight.

In a paper by Texas A&M scientists, biochar shows potential for increasing efficiency of the anaerobic digestion of animal manure.

Biochar is a charcoal material composed of agricultural by-products, including manure, crop residues and grasses. The substance can be used as a fertiliser and as a filter to remove contaminants from water and wastewater, including antibiotics, pesticides and hormones; in the process, biochar captures CO2 and ammonia.
