Abstract-The purpose of this study was to investigate the effect of Microwave (MW) power levels (480 to 1080 W) and sample mass (90 to 150 g) on the drying characteristics of the sewage sludge. The drying tests were carried out using a modified domestic microwave unit with a process control system. The results showed that drying rate was directly proportional to the MW power, but inversely proportional to the sample mass. The desired temperature could be achieved in short period of time at higher power level. MW drying showed a significant increase (from 5.65 MJ/kg to 18.75 MJ/kg) in calorific value of sewage sludge.

“…The mod-el used in [40] for incineration, and given in (1), depends on the LCV of the total generated organic and inorganic SW. The authors in [42] used model (2) for anaerobic digestion. Such model depends on the LCV of methane, the principal component of biogas derived from the fermentation of organic waste.…”

“…The expression for calculating the electricity generation potential of the total organic fraction of the MSW is given in (2). The efficiency of the process was 26%, which corresponds to a reciprocating internal combustion engine in the literature [42]: Although anaerobic digestion is carried out under controlled operation conditions, different values of methane generated from the OFSW have been reported. For the present study, 71 Nm 3 /T was selected, assuming a 55.5% methane in the biogas [46].…”

This study estimates the electric energy production potential from municipal solid waste in Colombia. The Colombian municipalities of Pasto (Department of Nariño), Andes (Antioquia) and Guayatá (Boyacá) were selected as representative populations of the national context because of their socioeconomic and demographic features, as well as the public availability of their waste management plans. The technical characteristics of two conversion technologies were analyzed: incineration (thermal conversion) and anaerobic digestion (biological conversion). From a technical point of view, the results showed that anaerobic digestion is feasible in all three scenarios, while incineration is viable in Pasto and Andes.

Gomez et al [15] presented a method for estimating the electricity generating potential from animal and human wastes in Spain. Fernandes et al [16] estimated the potential of biomass residues in a region of Portugal by using Geographic Information Systems (GIS) counting cultivated area of each species.…”
