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.

Abstract

In the persistent pursuit of alleviating the deleterious effects of malnutrition, particularly accentuated in vulnerable regions such as southern Madagascar, a comprehensive examination of the inherent capacities of botanical resources emerges as imperative. The current investigation thus endeavors to delve into the nutritional intricacies and underlying adaptations of four distinct cultivars of Mucuna pruriens, with the overarching objective of elucidating potential avenues for addressing the enduring predicaments of malnutrition, which corrodes the socio-economic fabric of indigenous communities while being exacerbated by the adverse ramifications of global climatic shifts. This rigorous inquiry is poised to scrutinize the diverse cultivars of Mucuna pruriens extensively, meticulously analyzing their nutritional profile encompassing both micronutrient and macronutrient constituents. The fundamental aspiration of this scholarly endeavor is to elucidate the underexplored nutritional reservoirs harbored within these Mucuna pruriens varieties, presenting auspicious prospects for fostering a more equitable and sustainable dietary paradigm. This entails employing a series of preparatory measures including soaking, dehulling, germination, cooking, and drainage, aimed at mitigating the presence of anti-nutritional elements, thereby optimizing the nutritional utility of the seeds.
