ELECTRONIC WASTE (E-WASTE) DISPOSAL IN TAMALE: THE SITUATION TODAY AND THE WAY FORWARD

The urban lifestyle which depends heavily on electronic gadgets has consequently increased the generation of e-waste significantly in urbanizing Tamale in recent years. Despite the dire environmental and health effects associated with this waste stream, Tamale currently has no formal strategy for its disposal. The aim of the study was thus to uncover current disposal practices to possibly inform the design of an appropriate disposal strategy. Using an interview schedule, data were collected f...

Assessing end of life vehicles’ environmental management systems in Kenya: the case of Nairobi city county waste management streams

Abstract: There is a growing evidence that some older cars are smuggled to the country, which is likely to cause serious environmental effects since the rise of the older motor vehicle population in the country results in the volume of ELV waste and hence the need to assess the ELV waste streams, especially in Nairobi City County of Kenya. Therefore, this study aimed at assessing the End-of-Life Vehicles’ (ELV) Environmental Management Systems in Nairobi City County, Kenya. The study used ...

Environmental effects and health risks associated with the location of Kalundu dumpsite, Kitui county to local residents

Abstract: The rapid growth of urban centres of developing countries has created challenging problems in waste management. This problem is exacerbated by resource constraints, extreme poverty, lack of practical waste management policies, and the inability of local authorities to provide for this basic function. Waste disposal onto dumpsites located in close proximity to human settlements is a challenge to the local inhabitants. In Kitui, generated waste is dumped in Kalundu, located in a resi...

Assessment of public-private partnership for solid waste management in Wote town, Makueni county Kenya

Abstract: Wote is a town in Eastern Kenya, Makueni County . Wote serves as the headq uarter of Makueni County and has a population of 9,875. The town has been experiencing rapid population growth. An increase in solid waste is observed due to increase in urbanization, population density and inco me, changing food habits, taste and pattern. T his study aimed at providing an alternative solution to the existing Solid Waste Management (SWM) systems . The study set out to investigate how Public ...

AMYLASE PRODUCTION FROM FUNGAL ISOLATES OF SPOILED FOODS AND DECOMPOSED WASTES USING SOLID STATE

Abstract: Amylases are important enzymes commonly used for the hydrolysis of starch to generate hydrolysates useful for different industrial applications. This study was aimed at isolating amylase producing fungal species from decomposed wastes and spoiled foods using solid state fermentation. The isolated fungal species were screened experimentally using the starch hydrolysis test and identified based on cultural and microscopic characteristics. Amylase activity was determined using the din...

PRODUCTION OF BIOGAS FROM GROUNDNUT SHELL (Arachis hypogaea) CO-DIGESTED WITH COW DUNG THROUGH ANAEROBIC DIGESTION

Abstract: Biogas is an alternative eco-friendly renewable energy source that produced by methanogenic bacteria through anaerobic digestion of organic materials. In this research, biogas production from co-digestion of the cow dung (CD) and groundnut shell (GS) with five mix ratios (T1 100%CD,T2 75%CD+25%GS,T3 50%CD+50%GS,T4 25%CD +75%GS,T5 100%GS) was evaluated under mesophilic conditions (38ºC) using batch fermentation for 21 days. The substrates were prepared with different total solid pe...

PRODUCTION OF BIO-GAS FROM ANAEROBIC CO-DIGESTION OF GOAT MANURE MIXED WITH CABBAGE (Brassica oleracea) AND CARROT (Daucus carota) WASTES.

Abstract: Biogas is a methane gas produced through anaerobic digestion fermentation of organic matter. The aim of this study was to determine the optimal mix ratio for biogas production from anaerobic digestion of vegetable waste (carrot and cabbage waste) and goat manure. The experiment was batch operated and daily gas yield from the mixture was monitored for 30 days. The parameters measured were total solids (TS), volatile solids (VS), organic carbon, and moisture content. For the experime...

PRODUCTION OF BIOGAS FROM ANAEROBIC CO-DIGESTION OF CORN COB WITH COW DUNG

Abstract: Production of biogas through anaerobic digestion of organic waste materials provides an alternative environmentally friendly renewable energy. In this study, biogas production from codigestion of corn cob with cow dung in five mix ratios was evaluated under mesophilic condition (38ºC) using a batch digester for 30 days. In all substrates, VS, organic carbon, pH and C: N ratios were measured before and after digestion. The Parameters studied were total solids (TS), volatile solids ...

EFFECT OF VARYING TOTAL SOLIDS ON THE YIELD OF BIOGAS FROM Datura stramonium LEAVES THROUGH ANAEROBIC CO DIGESTION WITH COW MANURE

Abstract: Production of biogas through anaerobic digestion of organic waste materials provides an alternative environmentally eco-friendly renewable energy. In this study, biogas production from co-digestion of cow manure (CM) and Datura stramonium leaves (DSL) in five mix ratios (100%CM, 60%CM:40%DSL, 50%CM:50%DSL, 40%CM:60%DSL and 100%DSL) were evaluated under mesophilic condition at 38ºC using a batch mode digester over 30 days fermentation. In all the treatments, physico-chemical parame...

VEGETABLE PRODUCTION WITH WASTEWATER FROM AKAKI RIVER IN ADDIS ABABA: PERCEPTIONS, RISKS, AND LOW-COST REMEDIATION

Abstract: The use of wastewater to produce food crops particularly vegetables is very prevalent within and outside the urban centers of developing countries. In the capital city of Ethiopia, Addis Ababa, where irrigation water for cultivation of vegetables is commonly derived from the polluted Akaki River, the practice has often been blamed for causing negative externalities to public health and the environment. To address these issues, the studies of this doctoral dissertation mainly focuse...

BIOGAS PRODUCTION FROM ANAEROBIC MONO AND CO DIGESTION OF POULTRY MANURE AND INVASIVE WEED SPECIES (Strigahermonthica)

Abstract: Bio-fuel production from agricultural, municipal, and industrial wastes through anaerobic digestion is meant for sustainable energy supply and eco-friendly waste management. Therefore, the objective of this study was to determine biogas yield using Strigahermontica as a solo substrate and co- digestion with poultry manure. The experimental analysis revealed that there was variation among the pH values of the substrates before and after anaerobic digestion. The mean pH value of the ...

CULTIVATION OF THREE SELECTED Pleurotus SPECIES USING GROWTH MEDIA PREPARED FROM SUGARCANE BAGASSE AND DRIED LEAVES OF Eichhornia crassipes AND Argemone ochroleuca

Abstract: Cultivation of edible mushrooms using agricultural invasive weeds could play a paramount role by producing foods with high nutritional value, and at the same time create environmentally friendly ways of food production. Thus, an experiment was conducted at Mushroom Research, Production and Training Laboratory of Haramaya University to cultivate three selected Pleurotus mushroom using three substrate and their combinations (dried leaves of Eichhornia crassipes (LEC) & Argemone ochro...
