    Energy recovery from municipal solid waste in Nigeria and its economic and environmental implications
    (Wiley Periodicals, Inc., 2019) Yusuf, R.O; Adeniran, J.A; Mustapha, S.I; Sonibare, J.A
    An assessment of potential biomass resources inNigeria for the production of methane and power generation is presented in this paper. Nigeria, as an underdeveloped and populous country, needs an uninterrupted source of energy. The country's energy problems have crippled large sectors of the economy. The percentage of people connected to the national grid is 40%. These 40% experience electricity supply failure on average 10–12 hours daily. Energy generation from municipal solid waste (MSW) is an effective MSW management strategy. Yearly waste generation has increased from 6,471 gigagrams (Gg) in 1959 to 26,600 Gg in 2015. This amount is projected to reach 36,250 Gg per year by 2030. Methane emission for 2015 was 491 Gg, and it is projected to reach 669 Gg in 2030. These values translate to 3.48 × 109 kilowatt hours (kWh) of electricity for 2015, with a projected 4.74 × 109 kWh by 2030. The revenue to be derived from the electricity that is generated could have been US$365.04 × 106 for 2015, and it is estimated that it will reach US$473.82 × 106 by 2030. It was found that methane emissions from MSW increased with time, and capturing this gas for energy production will lead to a sustainable waste management.

    Life cycle Assessment of a Petroleum Contaminated Soils Thermal Desorption Unit
    (Journal of Experimental Research. Published by Enugu State University of Science & Technology, 2020) Adeniran, J.A.; Mustapha, S.I; Yusuf, R.O; Baruwa, M.O
    Environmental issues involving the oil and gas industry have been growing in awareness; therefore high priority is given to waste handling and disposal. Although the thermal desorption unit (TDU) is meant to reduce the environmental damage of the waste from oil industries, it may also contribute to the damage. A way of putting this to check is by taking the life cycle assessment of the operation. This study presents the environmental impact assessment using a gate-to-gate approach of a thermal desorption unit in Nigeria, analyzed following ISO 14040 standards. GaBi software obtained from PE international was used to carry out the analysis with the management of 46,541,880kg of the waste mix for a period of 365 days considering the worstcase scenario as the functional unit. The results showed the fossil depletion is about 2,516,253 kg of oil equivalent, water depletion is 0.883 m and particles to air is close to 35% of the particles generated. Weak point analysis to show the unit with the greatest impact on the environment was also estimated by GaBi. This study proves that operation of a TDU can be certified eco-friendly.
