Greenhouse gas emissions from windrow composting of organic wastes: patterns and emissions factors

Urban Farm DB summary

A study measuring greenhouse gas emission patterns and emission factors from windrow composting of organic waste. The methane emission factor was 1.7 ± 0.32 g CH4/kg wet feedstock, CO2 was 19 ± 3.7 g CO2/kg, and nitrous oxide was below instrument detection limits. Life-cycle emissions, accounting for avoided emissions and carbon sequestration, were negative at −690 g CO2-e/kg, indicating a net mitigation benefit.
