ASSESSMENT OF AVAILABILITY AND ENERGY POTENTIAL OF THE AGRO-PASTORAL RESIDUES FOR ANAEROBIC DIGESTION IN DOKANME PUBLIC PRIMARY SCHOOL OF TORI BOSSITO (BENIN)

Abstract

The present study aims to quantify the agro-pastoral residues available in the municipality of ToriBossito and to assess the potential of said residues to supply the energy in Dokanme public primary school through anaerobic digestion. Field surveys were made to identify the different types of waste and the generation sites, then, based on statistical data collected and biogas productivity indexes from the literature the quantities of agro-pastoral residues, biogas and energy were estimated. The residues consist of cassava peelings, palm oil clarifying sludge and cow dung. The amount of cassava peelings that can be collected is estimated to 76.565 tons, 20075 liters for palm oil clarifying sludge and 118.260 tons for cow dung. A total energy potential in biogas from residues found to be 661.722 GJ. The exploitation of this energy resource can contribute to the conservation of forest and reduce women and schoolchildren occupation in searching for wood-energy.
