Abstract

Garri processing is a major agricultural and food related activity which leads to waste generation and this waste in turn constitute environmental problems in terms of stench smells and poor hygienic conditions that allow microbes and germs to thrive. Rural dwellers are normally poor thus the payment of electricity bills impoverishes them further. Inadequate energy supply and environmental pollution are gargantuan problems confronting Nigeria and many other developing nations of the world. In this research we estimated the cassava waste generation rate associated with processing of cassava for garri production activities and estimation of amount of biogas generation from specific mass of the waste. A simple digester is fabricated for sample digestion process. The result was then used in estimation of biogas generation potential of the garri processing mills. Five different garri processing activities were studied for statistical reliability of results. The results of the five studied garri production activities as described in the methodology were summarized in table 3.1. The quantities ��, ��, �� and ��� were directly measured as described while the ��� and ��� were calculated in each cell of table 3.1 as differences���= ��− �� and ���= ��−��. The sum of waste generated in each of the studied activity � is given in equation (3.1). The counted number of bags for each studied activity was given as. The estimation for daily generation of pressed bags of cassava by the community is ,�����= 44.35 bags.Keywords: Biogas, Energy, Cassava, Waste, Garri.
