    POTENTIAL IMPACT OF INDUSTRIAL SOLID WASTE MANAGEMENT IN ILORIN METROPOLIS.
    (Published by Faculty of Agriculture, University of Agriculture, Makurdi., 2019) Akpenpuun, T. D; Adeniran, K. A; Busari, R. A; Ajayi-Banji, A; Issa, B. B.
    Solid waste is an inevitable consequence of human activities on earth; hence an investigation was carried out to assess the impact of methods of solid waste management of selected industries on the environment in Ilorin metropolis. Two main tools used for the study were: a structured questionnaire and physical collection of solid wastes generated from the industries located within Ilorin metropolis. Percentages and charts were used in analysing the data. Sawmill waste recorded 98.69% out of the total weight of waste collected for the experiment. 1.04%, 0.22% and 0.04% were recorded for plastic, printing (papers) and films (publishing) industries, respectively. The results showed that 58% of the industries monitored their solid waste with 15% and 20% of PVC and sawmill industry, respectively. It was also observed that 20% of the respondents employ contractors for waste disposal, 6% deposit their waste at the dump site while 44% sell their industrial waste and 30% respondents burn their waste.

    Strength and Micro-Structural Properties of Wood Chips Composite Panel.
    (Published by Federal University of Technology Minna. Nigeria, 2020) Akpenpuun, T. D; Iyanda, M. O; Ajayi-Banji, A. A; Busari, R. A; Gbadeyanka, R
    Global warming primarily due to deforestation has led to the development of new materials to substitute felling of trees by wood-based industries. The utilisation of wood chips and cassava starch for the production of particle board was the thrust of this research. The chip sizes of 0.85 and 1.7 mm, dosage and types of binders (cassava starch, urea formaldehyde and Glutaraldehyde modified cassava starch) were the variables. The ratio of wood chips to the binders was 1.0:1.5. The boards were formed in rectangular moulds. Water absorption, thickness swelling, flexural tests and material characterisation (using scanning electron microscope (SEM)) were carried out. Data collected was subjected to analysis of variance. The result obtained was subjected to analysis of variance. The particleboards produced with modified cassava starch had the best mechanical properties with the modulus of elasticity (MOE) ranging from 5.90 to 32.32 N/mm2but had a higher thickness swelling values ranging from 3 to 59.37%. There was a significant difference (p<0.01) between the boards manufactured using plain starch and modified starch. These tests results have shown that wood chips, plain cassava starch and modified cassava starch are sources of raw materials in the production of particleboard. The developed particleboard can be used for paneling, partitioning and ceilings.
