Abstract

The challenge of sufficient sources of energy, the high cost of the available sources, and the emission of greenhouse gases harmful to both man and his surroundings amongst others, Initiate the need for renewable sources of energy that are available and affordable. This study focuses on the physicochemical properties of the substrate and digestate of biomass (fruit waste with sheep dung and food waste with human excreta). The hydraulic retention time was 30 days, within the mesophillic temperature range (30 – 40ºC) using a digester with 25 liter capacity, the biomass used was mechanically pre-treated. The pH of the medium reduced progressively from 7.75 to 7.45 and 7.4 to 7.25 for fruit waste with sheep dung and for food waste with human excreta respectively. This study shows that the synthesis of fruit waste with sheep dung and food waste with human excreta can produce sufficient carbon that will accelerate effective gas generation as an alternative energy source in Nigeria. Additionally, from the values of the physicochemical properties (nitrogen, phosphorus and potassium), the biomass is a good replacement for the conventional chemical fertilizer used on farms which are more expensive to come by
