Biomethane Potential of Some Agroresources in Burkina Faso: Case Study of Vegetable Residues, Pig Manure, Mango Waste and Bovine Manure
Journal Title: Journal of Advances in Biology & Biotechnology - Year 2017, Vol 15, Issue 2
Abstract
Burkina Faso urban area is confronted to hygiene, wash and energy supply problems due to an important demographic growth. Methanization of organic wastes has been demonstrated by several studies as a solution to energy crisis and environmental pollution. The aim of this study is to use anaerobic digestion process as a sustainable technology to produce biomethane from vegetable residues (VR), mango waste (MW), pig manure (PM), bovine manure (BM) in order to diversify the sources of renewable energy as well as to reduce environmental pollution in Burkina Faso urban area. The physicochemical parameters of these organic wastes were determined using standard methods (AFNOR, APHA) and the biogas produced was analyzed by gas chromatography. From the physicochemical analysis, dry matter rates were 22.61±0.3% for PM, 15.3±0.3% for BM; 11.78±0.6% for VR and 8.04 ± 0.02% for MW. The highest volume of CH4 was obtained with PM (17526.43μl CH4), followed by VR (14359.19 μl CH4), BM (12460.89μl CH4) and finally mango waste (12460.89 CH4 μl). The rate of CH4 content in biogas produced was 61.6%; 59.1%; 57.6 and 53.3 for PM, VR, MW and BM.
