The work aimed at determination of calorific value of municipal solid waste in Enugu, Nigeria and its potential for electricity generation. Random truck sampling was used according to American Society of Test and Material (ASTM) in the collection of samples at Ugwuaji landfill site, Enugu, Nigeria and calorific value was determined using oxygen bomb calorimeter. Enugu has a present population of 882,178 and the amount of municipal solid waste generated in Enugu was estimated to be 420 tonnes daily and this resulted in waste generation rate of 0.48kg/capita/day. The average composition of the municipal solid waste was 39% putrescible, 11% paper, 21% plastics, 5% textile, and 2% metal, 3% glass and 19% others. The average moisture content Volatile... |

The aim of the study is to determine the effect of ground insulation and feedstock on performance of fixed dome biogas digester. To achieve this, six identical fixed dome biogas digesters with volume of 32 liters were designed, constructed and used to carryout anaerobic digestion of three feedstocks namely cow abdominal waste, poultry droppings and 1:1 mixture of cow abdominal waste and poultry droppings. Three digesters were buried underground for insulation while the remaining three kept on the surface uninsulated. The ANOVA result showed that there were significant differences in the slurry temperature, volume of biogas produced and slurry pH respectively at 5% significant levels. The range of pH, Volume of biogas and slurry temperature (ST) in all the... |
