This is a poster of a simple experiment conducted to investigate the efficacy of the alkaline hydrolysis method on the depolymerization of post consumer plastic waste in Ghana. In Ghana, only about 10% of the waste plastics produced annually are collected for recycling. The remaining uncollected 90% lead to the pollution of the land and water resou...
Anaerobic digestion of multiple substrates can generate more biogas while remaining stable, if positive synergistic effects are achieved. The type of co-digested substrates and the mixing ratio used, are the most important variables as each substrate has unique set of characteristics.
Optimizing the volume ratios by testing various substrate mixing...
The study presents the results of the laboratory experiment performed on the anaerobic digestion of water hyacinth biomass harvested from the Volta River basin of Ghana and Fruit waste sludge as the inoculum. Batch mode of experiment was performed under mesophilic conditions (29 ± 3 °C) with a hydraulic retention time of 61 days. The experimental s...
Substituting biogas for Liquefied Petroleum Gas (LPG) in households is a long-awaited sustainable solution for the increasing cost of energy and large amounts of household human-generated waste. Nevertheless, a study of the characteristics of feedstocks is essential to maximise their energy potential. Consequently, this study examined the physico-c...
Nowadays, biofuel production has emerged as a suitable alternative means to hydrocarbon. This study assesses the possibility of producing biofuel from agricultural residue in The Gambia. It is also aimed to assess the feasibility of cultivating energy crops for the production of biofuel. The study revealed that there is a huge amount of agricultura...
The aviation industry is responsible for 12% of transport-related GHG emissions and 2–3% of the global GHG emissions, thus raising concerns for sustainable alternatives such as aviation biofuels. This study sought to analyze the potential of producing aviation fuel from rubber seed oil. Rubber seed oil (RSO) was extracted and the physicochemical pr...
The drive for a sustainable society and a circular economy has motivated researchers around the globe to turn to the transformation of renewable raw materials like biomass into value-added products that are akin or superior to their fossil counterparts. Among these biomass raw materials, cocoa pod husks (CPH) which is the non-edible portion of coco...
This study aimed at evaluating the potential biogas production from four main sources, in terms of the volume of methane for energy production and the equivalent avoidable carbon dioxide emissions in 2020 through to 2030. It was based on the projection of methane production from common livestock and poultry manure, possible landfills, wastewater tr...
Obtaining the comprehensive kinetics of elementary reaction steps in catalytic redox cycles remains a challenge. We report here an operando study by combined mass and UV–vis–NIR spectrometry to obtain kinetic data for reduction and oxidation steps in the catalytic cycle of ethylene oxychlorination on potassium-promoted CuCl2/Al2O3 catalysts and und...
The performance of CuCl2/Al2O3 with and without La and K promoters, designated as Cu, K0.23Cu0.77, K0.29Cu0.71, La0.29Cu0.71 and K0.21La0.08Cu0.71 was studied in the ethylene oxychlorination at 503 K and 1 atm by in-situ UV-Vis-spectroscopic kinetic study through a two-step approach. The effects of the dopants on the oxychlorination reaction were f...
In this study, we have developed a method to predict the steady-state rate and Cu oxidation state during ethylene oxychlorination from a reaction rate diagram of the individual steps involved in the catalytic oxychlorination cycle. The steady-state of the redox cycle is represented by a cross point of the reaction rates of the reduction- and oxidat...
Methane emission from livestock manure is increasingly contributing to the global green house gas emissions. In this paper the methane emission from cattle, pig, sheep, goat and chicken manure in four West African countries; Nigeria, Ghana, Burkina Faso and Mali were estimated. A systematic estimation of the methane emission was done based on the l...
Apart from waste treatment, anaerobic digestion is a reliable method for biogas generation. The digested sludge from anaerobic digesters can also be used to enhance the fertility of the soil. This paper assesses the biogas potential from the sewage generated in four public universities in Ghana for the 2008/2009 academic year. In the estimation of...
The associated harmful environmental, health and social effects with the use of traditional biomass and fossil fuel has enhanced the growing interest in the search for alternate cleaner source of energy globally. Ghana, a developing country depends heavy on woodfuel as a source of fuel contributing about 72% of the primary energy supply with crude...
