Co-composting Manure with Biochar to Meet Global Methane Goals
This paper in Environmental Science and Technology journal found that biochar-composting reduces CH4 by 79%, compared tocomposting without biochar. ABSTRACT: Livestock are the largest source of anthropogenic methane (CH4) emissions, and in intensive dairy systems, manure management can contribute half of livestock CH4. Recent policies such as California’s short-lived climate pollutant reduction law (SB 1383) and the Global Methane Pledge call for cuts to livestock CH4 by 2030. However, investments in CH4 reduction strategies are primarily aimed at liquid dairy manure, whereas stockpiled solids remain a large source of CH4. Here, we measure the CH4 and net greenhouse gas reduction……
