Abstract

The primary objective of this study is to explore sustainable alternatives to address the accumulation of waste resulting from the sisal exploitation in South Amboasary. Laboratory tests involving 8,000 g of defibration residues mixed with 1,600 g of inoculum over 69 days produced 355 liters of biogas, equating to 335 L/kg of dry matter with a methane content of 58% and a lower calorific value of 20,807 kJ/Nm³. These results suggest that biomethanation can valorize the 212,630 tons of sisal waste available annually, potentially replacing the 2,030 m³ of diesel consumed each year and meeting the domestic fuel needs of 16,575 households with eight members each. Additionally, a production of 137,800 tons of compost is projected to prevent the emission of approximately 7,000 tons of CO₂-equivalent toxic gases into the atmosphere. The technical feasibility studies for infrastructure implementation and project organization address several issues: local treatment of organic waste, creation of local jobs, energy independence, agricultural sustainability, and economic development.
