Assessment of solid waste characterization in Keffi Iga, Nasarawa State, Nigeria in view of adopting biogas technology for solid waste management

Abstract

The assessment of solid waste characterization in Keffi Local Government Area in view of adopting biogas technology for solid waste management was carried out. This was achieved through assessment of the quantity of solid waste generation and the composition (organic and inorganic) in the study area. Materials used for data collection are weighing scale and waste bins. Stratified and systematic samplings were used to select households for data collection. The selected households’ waste generation were observed and weighed on daily basis for one week and average weight was calculated for each household to quantify the amount of waste generation and composition. Solid waste generation per household per day in Keffi Local government area ranged from 0.9 Kg to 1.5Kg with mean value of 1.26Kg. There was a significant different (F>P@0.05) in the quantity of solid waste generation among the ten wards. Though, solid wastes in Keffi consist of diverse materials from both raw materials mostly farm/animal residues and manufactured goods, it has higher organic (71.79%) than inorganic (28.21%) components. Thus, it was concluded that adoption of biogas technology for solid waste management in Keffi Local Government Area is feasible based on waste characterization of the area. Pilot demonstration of biogas production from organic waste was recommended
