Item Comparative Analysis Of Tomato Plant (Lycopersiconesculentum) And Stubborn Grass (Eleusineindica)In The Phyto-Remediation Of Soils Polluted With Heavy Metals(Department of Agricultural and Environmental Engineering, University of Ibadan, Nigeria, 2015) Omobowale M.O.Item Impact of cleaner production practices in the nigerian wood industry on sustainability and environmental performance(2023) Adeniran D.A.; Omoniyi T.E.Wood residues generated in Nigeria amount to approximately 5.2 million tonnes annually, highlighting the resource-intensive nature of the Nigerian wood industry. Cleaner production practices, which involve the identification and implementation of strategies to reduce raw material consumption, energy use, waste generation, and pollution, have been widely adopted in many countries. However, in Nigeria, the adoption of cleaner production practices remained limited. This study aims to review the potential impact of cleaner production practices in the Nigerian wood industry on productivity and the creation of a sustainable environment. It sheds light on the unique characteristics and challenges faced in the Nigerian wood industry that influence the widespread adoption of cleaner production practices. The study delved into the different phases of cleaner production implementation, emphasizing the importance of planning, implementation, monitoring, and evaluation. It highlighted the adoption of low-cost and practical cleaner production measures, debunking the misconception that cleaner production implementation is always costly. Furthermore, the study examined the prospects and challenges of implementing cleaner production measures within the specific context of Nigeria's peculiarities. It discussed comprehensive waste management strategies, noise control measures, materials modification, and substitution, as well as the application of cleaner production practices on machinery and equipment. The paper emphasised the need for stronger policies and their enforcement to ensure compliance with cleaner production practices in the wood industry. By promoting the adoption of cleaner production measures, the country can witness enhanced productivity, minimise waste, and create a sustainable and environmentally friendly wood industry sector.Item Fuel energy potential of pyrolyzed municipal solid wastes(2021) Okareh, O. T.; Adegoke, S. O.; Richard, R.; Akintola, S. A.; Adeleke, A. A.; Ikubanni, P. P.Municipal wastes have become a menace and the recycling of these wastes has been the focus of many researches. In this study, municipal plastic wastes were converted to energy fuel using pyrolysis using a locally fabricated vacuum pyrolyzer. 6 kg of municipal plastic wastes (PP, PET and PS) were collected, grounded into chips using a knife milling machine and were fed into the pyrolyzer to undergo thermal degradation at a temperature of 500oC with holding time of 4-5 hours. The pyrolyzed oil was collected into a Pyrex condenser unit and subjected to pseudo-distillation at 100oC to obtain the volatile com-ponents. The percentage pyrolyzed oil mass yield was calculated using mass balance equation. The liquid fuel was analyzed for its physical properties using ASTM methods, while the chemical properties were characterized using FTIR and GC-MS. The pyrolytic process showed the percentage mass yield of the pyrolyzed oil for the municipal plastic wastes oil, char, and non-condensable gas as 82.0, 16.0 and 2.0%, respectively. The derived energy fuel indicated a cloud point, pour point, density and flash point of -26.0oC, -28.0oC, 0.839 g/cc, and 50.0oC and -28.0oC, -35.0oC, 0.744 g/cc, and 30.0 C for pyrolyzed oil and distillates oil, respectively. The FTIR and GC-MS results of the liquid pyrolyzed oil indicate the presence of aliphatic, alkane, alkene, and aromatic hydrocarbons of carbon number C9-C44 in the energy fuel. Physicochemical characterization of the recovered oil indicated similarities with the conventional fossil fuels. The technology has proven to be effective in solving the environmental problems.
