“…The correlation between high recycling rates and the adoption of waste-to-energy treatments for commingled residual waste was also evidenced in a recent study (Castaldi and Themelis, 2010). Magrinho and Semiao (2008) evidenced that although recovery of paper and plastics reduces the Lower Heating Value (LHV) of the residual waste, this decrease may be compensated by the diminution of the moisture content of the waste due to separation of humid fractions.…”

Abstract:In this paper, on the basis of a detailed characterisation of the Municipal Solid Waste (MSW) generated in the city of Rome, different integrated management strategies regarding both source separation of selected fractions and the treatment and disposal of the residual commingled waste were compared and discussed in terms of achievable material and energy recovery. The main findings of this study, that can be extended to other regions characterised by similar environmental policies and social and economical conditions, showed that source separation percentages cannot realistically exceed certain maximum percentages, particularly when they are addressed at selecting waste fractions for recycling. Regarding the management of the residual commingled waste, thermal treatment of all the fractions for which no further material recovery can be realistically pursued resulted the most convenient strategy in terms of recoverable thermal energy.

“…With regard to heating value, it is estimated for each MSW fraction in the form of LHV using formulas presented by Meraz et al [19] and Magrinho and Semiao [20]. The final value for the mixture is calculated as a weighted average from LHV of the individual MSW material fractions.…”

“…Apart from food and paper wastes, plastic wastes constitute major municipal and industrial wastes in cities of the world, including the high economic cities (Panda et al, 2010;Singer, 1995). For instance, the United States of America (USA) alone generates more than 170 million tons of plastic waste (Magrinho and Semiao, 2008;Ahmaed et al, 2011). Of these, only 13% is recovered, 14% used for energy, and 73% dumped into landfills (Magrinho and Semiao, 2008;Ahmaed et al, 2011).…”

This is an indication that enormous amounts of solid wastes are accumulated, which if not properly handled could lead to environmental hazards.…”

This study attempted to synthesize and characterize engine oil additives from plastic waste, i.e., low density polyethylene, high density polyethylene, and poly propylene for the purpose of improving the viscosity index and pour point of engine oils. To do this, the starting polymers were reacted with maleic anhydride in a chain growth addition polymerization. The reactions took place in a muffle furnace at 230°C. The product poly (alkenymaleic anhydride) was then reacted with a glycerol at 140°C in a step growth addition polyesterification in the presence of xylene and nitrogen. The product formed, i.e., monoester acid, was then reacted with diethylene triamine in a step growth condensation polyamidation to produce the additive. The results obtained showed that the utilization of the additive produced from poly propylene as an additive on the base oils, i.e., SN150, SN500, BS 150 and commercially available oil (YT3513), gave the best results. The optimum blending concentration of 60 g/dl was achieved for the base oils except BS 150, which was 50 g/dl. Results also indicated that the optimum weight percentage of the blended additives was 3 wt%, while the optimum viscosity index was 162, 160, 159, and 186 corresponding to an increment of 80, 64.42, 36.76, and 36. 76% for SN150, SN500, BS150, and YT3513, respectively.
