Optimization of oxygen consumption and reduction of organic matter from waste during the fermentation phase: Case of the composting platform in Lom, Togo

Abstract

In the context of carbon financing it is required that the rate oxygen inside the windrows exceeds 8% to avoid anaerobic decomposition. Thus, the objective of this study is to optimize oxygen consumption and  reduce organic matter in the waste during the fermentation phase. Windrow turning is monitored, which includes monitoring of temperature, pH, organic matter, humidity and certain metals.Temperature monitoring showed a gradual decrease until stabilization at room temperature, indicating the maturity of the compost. With a slight increase in all swaths, the pH remained alkaline. The humidity in the windrows promoted good aerobic degradation of the composted waste. The organic matter in these windrows has decreased to values ??that agree with standards. The present study has demonstrated the importance and influence of the oxygen content and the production of carbon dioxide on the mineralization of organic matter, especially during the fermentation phase.   Key words: Flipping, compost, oxygen and carbon dioxide levels.
