“…V CH4 is then converted to tons of oil equivalent (toe). In standard temperature and pressure conditions, 1m 3 of methane is equivalent to 8.47x10 -4 toe and 5.2x10 -3 tons of wood [23]. The energy potential E is then obtained by equation 9.…”

Aims: Evaluate the available dry matter deposit of crop residues and assimilated as well as its methanogenic and energetic potential in the agro-ecological zone 5, in Benin. Place and Duration of Study: Rural Engineering Laboratory, National University of Agriculture, Benin, between October 2021 and October 2022. Methodology: This evaluation was done through a prospective approach based on the Solagro-Indigo method. The potential yield was evaluated using national agricultural statistics and the residue-to-product ratios available in the literature. An exploratory survey was conducted to evaluate the availability of residues in the study area. The methanogenic and energetic potential was determined from the specific bio-methane potentials of each type of residues from previous studies. Results: This study shows that 71% of the total dry matter produced is not valorized. This important deposit represents more than 248 million cubic meters of methane and is equivalent to approximately 210 kilo tons of oil equivalent and more than 100% of the total wood energy needs in the region. Additional studies on the optimal conditions for digestion of the main residues identified could promote initiatives for their valorization. Conclusion: The assessment of agricultural residues potential in the ZAE5 revealed a huge deposit of organic matter that is underpriced and largely abandoned with considerable energy potential. Data are available for each commune and could be used for municipalities development strategies. However, an in-depth study of the optimal methanization conditions and more accurate and precise spatial analyses should be carried out for implementation for energy valorization initiatives.

This research evaluated the technical and economic feasibility of a biogas plant in the south of Chile to generate energy (WtE) for the plant’s own consumption, energy for sale to the country’s electricity grid and produce biofertilizer from municipal solid waste (MSW). In the town of Panguipulli, 26 tons of solid waste are produced daily, of which 12 tons correspond to household organic waste. These arrive directly to a landfill, wasting their potential to generate products and energy. To study the economic feasibility, an analysis was carried out on the investment, costs and income that make up the cash flow of the project evaluated at 15 years. The results gave an NPV of 214.099.637 CLP and an IRR of 15% at a real discount rate of 10%, with a payback period of 6 years. The research concluded that it is feasible to design a biogas plant that works from household organic waste in Panguipulli. This will contribute to the mitigation of climate change and will promote circular economy actions and the sustainable management of MSW in the south of Chile.
