Development and Evaluation of the Performance of Palm Kernel Shell (PKS) Grinder (Published)

The suitability of grounded Palm Kernel Shell (PKS) as a friction material in formulation of non-asbestos brake lining, and component of concrete block to increase the strength is an important innovation in our recent Time. The objective can only be achieved if Palm Kernel shell is grounded to different sizes to suit the required objective. Therefore, there is need to develop a Palm kernel shell grinding machine for which this purpose is intended. The developed Palm kernel shell grinder comprises barrel, formed worm shaft, abrasive discs with mechanism for clearance adjustment, prime mover, belts, bearings, pulleys and discharge chute. The developed grinder was tested and the result showed that the machine could pulverize PKS within a range of 75   to 4 mm grain sizes. The report established significant potentials in the diversification of palm kernel shell from waste to sources of incomes to stakeholders most especially in the manufacture of brake lining and production of reinforce concrete block.

Statistical Survey of Waste Management in Osun State, Nigeria: Binary Logistics Approach. (Published)

This research work is in line with the strategic priorities of environment management agencies, and has the potentials to assist the organization in their effort to ensure the efficient management of solid and liquid waste in the City of Osogbo.  With a view of providing empirical data information with respect to the causative factors responsible for the visible environmental pollution by wastes and materials from food outlets. Data was gathered from a representative sample of 332 food outlets on socio-economics demographic, environmental, sanitary and health related variables that are related to waste analysis was performed using statistical procedures such as frequency tables, pearson’s chi-square tests of association and binary logistic regression analysis in the statistical package STATA version 10. Odds rations estimated from logistic regression analysis were used for identifying key factors that affect efficiency in the proper disposal of waste. Results obtained showed that 18% of the 332 food outlets in the study were generally inefficient in waste disposal. Based on odds rations estimated from binary logistic regression analysis, wrong perception (a factor of 10.88), failure to provide trash cans to customers (a factor of 3.15), the operation of food outlets by non-owners of managers (a factor of 2.33), factors that affect the proper management of waste at the 332 food outlets in the study.

Environmental Adult Education for Preventing Lassa fever Outbreak in Nigeria (Published)

The incidence of Lassa fever outbreak in Nigeria, is worrisome and this is attributed to indiscriminate waste disposal habit of people. Waste not properly dispose attracts rodents, which are the primary carrier of Lassa virus that causes Lassa fever. In other to make our environment free form Lassa fever spread, waste disposal habit of people needs to be taken care of. This paper thus examined how environmental adult education programmes such as hygiene and waste disposal education which are components of health education can be utilized to inculcate proper waste disposal habit among city residents in Nigeria. Through this paper, the authors established that for creating a Lassa free environment through hygiene and waste disposal education, the design of the hygiene and waste disposal education programme should be based on four strategies which will convey information, build understanding, improve skills, and enable sustainable actions

Perceived Effect of Waste Generation on the Climate among Rural Households in Oyo State, Nigeria (Published)

This study examined the perceived effect of waste generation on climate change among rural households in Oyo state, Nigeria.  Two local government areas were randomly selected from the three senatorial districts in Oyo state from which five villages each were randomly selected. A total of 15 households across the selected villages were randomly selected to give a total sample size of 150 respondents. Data were collected through the use of interview schedule and analyzed using frequencies and percentages to present the descriptive analysis, while Pearson Product Moment Correlation and Chi- Square were used for inferential analysis. The findings of the study revealed that the average age of the respondents in the study area was  37 years, as majority (75.0%) were married  and had no formal education (63.2%).  Majority (90.0%) were farmers, had small farm size (86.1%) of range 1-5 acres. Kitchen waste (94.7%), crop waste (88.8%) and animal waste (65.3%) were the major waste generated within the households in the study area. Most (92.0%) of the respondents disposed their wastes making use of sacks (83.3%) 62.0% and 74.7% dispose their waste into drainage channels (62.0%) and flowing stream (74.7%) respectively. Few (14.7%) obtained information on waste management practices through the radio. Majority (78.2%) had low knowledge level on waste management practice and wrong perception (79.2%) of the effects of waste generation to climate change. Level of education (2 = 9.273, sources of information on waste management practices (r = 0.325) and knowledge on waste management practices (r = 0.276) have influence on the perceived effect of waste generation to climate change. There is the need to create awareness on the environmental effect of waste and inappropriate waste management practices among rural households.

Environmental Impacts of Roadside Disposal of Municipal Solid Wastes in Karu, Nassarawa State, Nigeria (Published)

The paper looked at municipal solid waste generation, disposal and the consequent environmental impacts Primary data was generated by carrying out oral interviews and field observations for holistic and in–depth assessment of the environment and the secondary data was obtained from desk review method, information on effects of municipal solid wastes on environment were obtained from relevant literatures. The interviews were semi-structured and a purposive sampling method was adopted and analyzed descriptively. The results of the findings showed that population growth and unplanned urban expansion has exceeded the expected limit in recent time with resultant ugly system of solid wastes disposal. Municipal solid wastes which contain both biodegradable and non-biodegradable wastes are disposed at the shoulders of major highways in temporary dumpsites and are later evacuated by a waste management agency on a weekly basis. There is no organized house to house or street to street collection of the solid wastes. The study revealed that roadside disposal of municipal solid wastes has serious impacts on the environment. Some of these impacts include physical nuisance of the solid wastes to the environment, the solid waste dumps also serve as hideouts for rodents and snakes which are dangerous. The solid wastes are blown around by wind making the environment filthy, most of the wastes are also been washed by overland flow during heavy downpour to block drainage channels and subsequently lead to flooding of the environment. Most of the non- biodegradable solid wastes contain toxic chemicals which have serious implications on the environmental sustainability and human health. The paper therefore recommends that Government should come up with proper orientation and environmental laws should be put in place for the general public and also to provide necessary facilities and arrange for better methods of collection of solid wastes.
