Electrocoagulation (EC) is an efficient electrochemical method for treating water using electric charges to destabilize and coagulate pollutants. In this study, a bipolar electrocoagulation reactor with aluminum electrodes was used to treat selected industrial wastewater. Key parameters, including odor, turbidity, Color, and other physicochemical p...
Groundwater, an essential freshwater resource, is critical to life and supports various industries. Unrestrained urban expansion and inefficient waste management practices endanger groundwater quality. This research examines the groundwater quality and impacts of the Refuse Waste Dumpsite located at Awotan, Ibadan. Additionally, this study provides...

The tangible effects of climate change and the influence of environmental factors on climate have driven a shift towards cleaner and more sustainable energy sources. This study investigates the effects of biochar and zeolites in the anaerobic digestion (AD) and co-digestion processes of cassava wastewater (CW) with livestock manure, aiming to asses...
In the face of the rapid rise in global waste production and the pressing need to shift towards sustainable energy options, advanced Waste-to-Energy (WtE) technologies have emerged as a highly promising solution. These innovative technologies effectively utilize waste as a valuable resource, presenting a viable pathway for sustainable energy recove...
The University of Ibadan, with approximately 26,000 students, has been struggling to maintain a clean and healthy environment. To address this issue, this project was undertaken to develop a "triplet waste bin" model. The first bin, designed to collect plastic bottles using computer vision, while the second and third bins are for collecting biodegr...
Remanufacturing is the process returning a used product to at least Original Equipment Manufacturers' (OEM) original performance specification from the customers' perspective and giving the resultant product a warranty that is at least equal to that of a newly manufactured equivalent. Remanufacturing process is commonly split into six processes. Th...
This project work examined the level of groundwater contamination close to the solid waste dump site at Agbowo Community in Ibadan. The major aim of this study is to determine the effects of solid waste on groundwater quality used for domestic purposes. Specific objectives were to determine the physical and chemical characteristics of the water sam...
The lack of and need for modern quality medical equipment in developing African countries has steadily increased with increasing population, leaving these countries to depend heavily on donated medical equipment from developed countries. Most of these secondhand and old medical devices which are most often not suitable for or suited to use in devel...
Currently, there are challenges with proper disposal of cassava processing wastewater, and a need for sustainable energy in the cassava industry. This study investigated the impact of co-digestion of cassava wastewater (CW) with livestock manure (poultry litter (PL) and dairy manure (DM)), and porous adsorbents (biochar (B-Char) and zeolite (ZEO))...
Phytotechnologies have emerged as an offshoot from wetlands. They are being applied globally as a low-cost option to treat wastewaters, such as runoff, greywater, municipal wastewater, waste leachates and industrial effluents. They are simple technologies with a few or no mechanical parts, consisting essentially of a basin with water, a substrate (...
Biomedicalengineering (BME) programmes are relatively few in Africa.It was reported in 2008 that only twelve African universities in only six countries offered biomedical engineering compared with 229 universities in North America (Abu-Faraj, 2008). As at 2015, there was less than 0.01 biomedical engineer per 10,000 population in Ghana compared to...
Small and Medium Size Enterprises (SMEs) are encouraged by Nigerian Government to develop and sustain the economy and promote employment. They range from process industries, fabrication workshops, service centres, food and drink premises, and several others. A majority of these sprawled up in urban areas though they are also seen in peripheral and...
