| Abstract | Understanding the quantity of waste generation in a locality and its characteristics are important to estimate the reuse and recyclability potential. This study was a similar attempt to conduct Municipal Solid Waste (MSW) assessment and characterization for proposing a suitable energy recovery options in Phetchaburi province in Thailand. Three out of 15 municipalities in the province were selected as the study sites. Material Flow Analysis (MFA) was used for quantification of the flows and accumulations of MSW. The waste composition and waste characterization followed the American Society for Testing and Materials ‘Standard Test Method for Determination of the Composition of Unprocessed Municipal Solid Waste (ASTM D 5231-2003)’. Based on these local MSW characterization, an appropriate waste to energy recovery option was recommended using Sustainability Assessment of Technologies (SAT) procedures. Results of MSW composition analysis indicated the presence of 51.84% of biodegradable wastes, 36.75% of combustibles and 11.41% non-combustibles. MSW had higher moisture content (65%) and C/N ratio (52:1). 72.54% of volatile solids, 10.15% of fixed carbon, and 17.31% of low ash content as dry basis were present in the MSW sample. Average carbon, hydrogen, nitrogen, sulfur and oxygen of the MSW constituted approximately 47.94, 6.90, 0.92, 0.16 and 26.77%, respectively. The chlorine content was 0.62%. The top three highest components of ash analysis were 19-27% of SiO₂, 16-24% of CaO, and 10-17% of Fe2O₃. The gross calorific value observed as dry basis ranged from 4,341-4782kcal/kg. Heavy metal presence was highest for Cr (1,171mg/kg), and the lowest for Hg (<1 mg/kg). Total MSW generation of 21,975, 20,114, and 18,632 tonnes per year were generated in Cha Am Town Municipality, Tha Yang Sub-district Municipality, and Phetchaburi Town Municipality, respectively. Of this total MSW generated, significant amount of MSW of 95.50, 90.24, and 6.00%, respectively were accumulated in sanitary landfill, landfill, and transfer station, respectively. Only 4.5, 9.8, and 5.4% of the total MSW generated in Cha Am Town Municipality, Tha Yang Sub district municipality, and Phetchaburi Town Municipality were being recovered for recycling. Refused Derived Fuel and Anaerobic Digestion technologies were ranked as the most appropriate technologies considering the local waste composition and characterization from Phetchaburi province. |
