Characterization of Gosa Municipal Solid Wastes at Abuja, Nigeria

Abstract

The study examined municipal solid wastes characteristics of Gosa dumpsite at Abuja, Nigeria. Waste characterization has not yet been given adequate attention in management of waste in Nigeria and it is a major problem that affects waste materials handling and recovery processes. Wastes samples from Gosa waste dump site, Abuja, were randomly collected and subjected to moisture content, composition, density and size distribution determinations according to prescribed standards in literature. The moisture content of the Gosa waste solid was 19.3%. The results of the characterization of the Gosa municipal solid wastes show 34% organic, 10% paper, 28% plastic, 2% glass, 6% metal, 4% fabric, 2% rubber and 14% dust. The average density of glass, metal, plastic, fabric, rubber, paper, organic and dust materials were 0.044 kg/m3, 0.045 kg/m3, 0.176 kg/m3, 0.043 kg/m3, 0.042 kg/m3, 0.074 kg/m3, 0.143 kg/m3 and 0.098 kg/m3, respectively. The size distribution of the Gosa solid waste ranges from 10-28 cm for metals and plastics and 3-13 cm for paper and glass. The rubber had size ranges from 8-23 cm while size ranges of organic was from 3-6 cm. The large presence of organic, plastic, paper and metal wastes at Gosa waste dump site, is an indication that the municipal solid wastes can be sorted, recycled and processed to other useful products, using the characteristics as a guide.Keyword: Characterization, Density, Municipal Solid Waste, Size Distribution, Waste Management

Heavy Metal Tolerance of Bacterial Isolates from Solid Waste Dumping Sites in Abuja, Nigeria

“…The implication of this finding is that majority of the Cr, Ni and Pb tolerant-bacteria were predominantly distributed in soil samples from Gosa and Gwagwalada dumpiste, probably due to the huge volumes of solid wastes disposed at these locations over the years. According to previous studies Gosa and Gwagwalada dumpsites are the most famous and voluminous solid waste dumping site due to their strategic locations to municipal, industrial and commercial waste generation centers (Sawyerr et al, 2017;Ojiego et al, 2019;Saidu et al, 2021). The dumpsites are used by farmers for planting mostly vegetables and maize and thus, identification of the metal tolerant bacteria will be significant in proper bioremediation of the heavy metals at the sites by the bacterial agents.…”

Physicochemical Characterisation of Abuja’s Municipal Solid Wastes as a Renewable Energy Resource

“…Abuja which principally constitutes the Abuja Municipal Area Council has a central government institution responsible for solid waste management in the City known as the Abuja Environmental Protection Board (AEPB) with a statutory mandate covering city cleaning, street sweeping, litter control, solid waste collection and transfer and vegetation control. The F.C.T has waste dumpsites located in all the area councils including those located at Mpape, Gosa, Ajata, Karshi and Kubwa to serve the municipal area [9].…”

“…The sample is contained within the bomb, which is immersed within the water contained by the calorimeter bucket. Applying the First Law of Thermodynamics to this system gives, (Equation 9): (9) https://doi.org/ U is the change in internal energy of the system; is the heat transfer at constant volume. W is work performed on or by the system.…”

Household Waste Reduction Practices in Ibadan, Nigeria

“…By 2050, there will be 3.4 billion metric tons of municipal solid waste produced worldwide, an increase of around 70%. Numerous factors, such as changing consumer purchasing habits, population growth, urbanization, and economic expansion, are to blame for this (Abumere and Filani, 1986;Bamgboye & Ojolo, 2004;Imoh & Emmanuel, 2011;Ian Tiseo, 2021). Globally, both rural and urban dwellers generate millions of tons of waste yearly, this portends a grave challenge to everyone (ChineduIke et al, 2018).…”
