Assessment of Agricultural Biomass Residues for Anaerobic Digestion in Rural Vakinankaratra Region of Madagascar
نویسندگان
چکیده
This study estimates agricultural residue biomass available for biogas generation in smallholder farming systems the rural Vakinankaratra region of Madagascar, during 2017–2018. Estimations were done using a combination household surveys, literature models, and publicly data. Manure from four types farm animals 17 ten crops assessed. In studied period, gross produced animal manure crop 19.4 ± 7.41 7.3 1.08 tonnes fresh weight per year household, respectively, which up to 54% 83% are estimated as recoverable production bioenergy area, respectively. indicate that have potential generate 291 92 745 122 Nm3 methane equivalent 10.5 3.34 26.8 4.28 GJ heat energy residues, Theoretically, average can result complete substitution domestic fuels households. Approximately 0.12 nitrogen be recovered digestate (using all types) after recovery, employed fertilization. The corresponds 0.26 urea fertilizer year. investigation shows anaerobic digestion based on has meet significant portion needs farmers Madagascar make an important contribution providing on-farm use.

15 صفحه اولQuality and function of anaerobic digestion residues
The growing number of biogas plants in Europe has resulted in increased production of nutrient-rich digestate, which has potential as fertiliser on arable land. Many different organic materials can be degraded in the anaerobic digestion process, with most macronutrients and micronutrients retained in the digestate. Depending on the ingoing organic substrate and management of the biogas process,...
