The Recovery of Municipal Solid Waste (MSW) into Biogas Using Accelerated Processing. The Case Study: Ouargla City in Sahara- Algeria

Abstract

The study aims is to accelerator (reducing time) of the process of the digestion anaerobic and increasing the amount of biogas using accelerator; this technology allows for reduced the municipal solid waste (food) - based organic material (that is to say the achievement of zero food waste, especially after development urban digester in the neighbourhood and smart trash). In consequently, the study complemented the results of preliminary research, who to show the importance of proteins and fatty in municipal solid waste (MSW) to the production of biogas to the natural’s deadlines in phase mesophile and thermophile for methanogens to function properly in 40 days. The obtained results through a reactor for anaerobic digestion (from the experimental condition at 37°C and 60°C), at representative sampling municipal solid waste of Ouargla city in Sahara –Algeria, in terms of quantity and quality, clearly show: 1. The impact of Aspergillusniger accelerator in reducing the extreme production biogas time in the digester in experience 1, recording respectively in 37°C and 60°C: 208.5 ml and 99.6 ml (in 19 days), compared experience 2 without accelerator in 37°C and 60°C: 140.3 ml and 207.5 ml (in 39 days). These results show (doubtless) the impact of accelerators of reducing time producing biogas in 37°C by 100%; on the other hand, the accelerator does not give significant results for increasing biogas production. 2. This result of reducing time producing biogas this will (undoubtedly allow) us the innovation of a digester household biogas digester in the residential neighbourhood and smart trash in homes (that is to say the achievement of zero food waste).
