In this study, aluminium (Al) ingot prepared from beverage can scraps (BCS) was characterized. The composition, density, tensile strength, compression strength, wear rate, thermal conductivity, hardness, storage modulus, loss modulus and microstructure of the recycled Al ingot were determined. The result of the analysis showed the composition of the Al ingots to be 95.62%Al, 1.62%Mg, 1.32%Si, 0.693%Mn, 0.437%Fe, 0.162%Cu, 0.097%Zn, 0.024%Ti, 0.017%V, 0.006Ni, 0.005%Cr and 0.008%Pb. The density, ultimate strength, yield strength, percentage elongation, compression strength, hardness, wear rate, coefficient of friction, thermal conductivity and coefficient of thermal expansion of the Al ingots are 2.62gcm -3 ,138.03Nmm -2 , 118.65Nmm -2 , 0.9%, 411.15 Nmm -2 , 65.67HV, 0.12 mm 3 n -1 m -1 , 0.56, 191.58Wm -1 K -1 , and 0.11 o C -1 . The values of these properties fall within the range of the density and strength properties of standard Al alloys. Also, the peak values of the Loss modulus and damping coefficient obtained through the dynamic mechanical analysis of the recycled Al ingot are 1118Nmm -2 at 46 o C and 0.029 at 45.8 o C respectively. The lightweight, high thermal conductivity, good wear resistance and good strength properties will make Al ingot good for use in structural application such as brake disc.

Introduction A waste material refer to materials that are abandoned or discarded as refuses or scraps when they reach the end of their life cycle or when their contents are consumed or extracted. Waste materials result from activities in the manufacturing, food processing and agricultural industries (Anyanwu et al, 2013; Rosenkranz et al, 2011). Municipal solid wastes (MSW) exist in large quantity and their constituents (rubber, plastics, papers, glass, metal scraps (Al scraps, tin & cans), ceramics, wood, textiles, compostables, vegetables, water sachets and cellophane packages, ash, etc.) vary due to increase in food processing, construction and agricultural activities. Nigeria is one of the biggest contributors of solid waste in Africa with an estimated 32 million tons each year; yet only few states provide landfills or dumpsites for the MSW (Obi et al, 2016). In fact, the management of MSW in most developing countries remain a big challenge. Mostly, MSW are dumped in open places and this has been a major source of ecological challenges - blocking water ways and occupying land space. Also, the burning of MSW indiscriminately has resulted to environmental pollution due to emission of gases (Andreas, 2014; Davies, 2015; Adeyi, 2010). In Nigeria, MSW generated per capita per day in Lagos, Kano, Ado Ekiti and Markudi is 0.63kg, 0.56kg, 0.71 and 0.48kg respectively (Akindayo, 2019; Obi, 2016; Babayemi & Dauda, 2009). Akindayo (2016) wrote on the MSW management and the inland water bodies: Nigerian perspectives listed the components of MSW in Nigeria to include: rubber, paper, plastics, glass, Al scraps, metal scraps, tin and can scraps, food, wood, leaves, etc. The quantity of each of waste’s component varies across the different states in Nigeria. Konya et al (2013) in their study titled ‘Characterization of wastes and their recycling potentials ; a case study of East-West road, Port Harcourt’ discovered some common wastes at the receptacles were cartons, papers , animals bones, plastics , Al plates, nylon bags, ceramic materials, vegetable stems, hospital wastes, old and damaged electronics, old computers, photocopying machines, Al cans, etc. It was observed that: plastics, and Al
