Abstract

This study investigated the greenhouse gas emission of compost products from community composting plants. Aged wastes from agricultural and agro-industrial sources used as raw materials for composting with intermittent forced aeration static pile composting application. Investigation of two types of compost products, including powder and granular shapes, revealed that the powder composting process emitted CO2 and CH4 gases as 730.23 kg and 4.81 kg, respectively, during the composting process, while the granular composting process emitted 784.38 kg CO2 and 3.39 kg CH4. An additional liquid mixture for granular formation contributed to higher emissions of CO2 and CH4 compared to the powder composting process. These data are useful for conducting life cycle assessments to evaluate and improve the environmental performance of community composting systems.
