Abstract

The recycling of waste into biogas inevitably occurs in hermetically sealed enclosures called bio-digester. Our study focuses on the recovery capacity of slaughterhouse waste by a tarpaulin bio-digester installed at the Dakar abattoir with a capacity of 4000m3 including a digester of 2500m3 and a gas meter of 1500m3. During our work, we have tried to understand the primordial factor favoring the obtaining of biogas in quantity. The studied system being in industrial size, the water retention time was programmed over 40 days according to the data of the company and according to the characteristics of the substrate, the pH was observed, and the temperature set on a mesophilic range. We have noticed that the considerable increase in wastewater (blood + wash water) for a minimal amount of rumen content is favorable to a better biogas yield. It shows that the content of our biogas consists mainly of CH4, CO2, O2, and H2S measured using a Severin Multitec 540 Device for the analysis of biogas in the field. (Quality feature on 1m3 of biogas produced). The biogas is then purified and used to power a cogeneration engine, generating electricity and heat. The implementation of this digester has made it possible to solve an environmental problem related to the waste and the valorization of the latter as essential energy for the study system.
