Abstract
Open burning of municipal solid waste (MSW) and agricultural waste (AW) causes environmental problems. This work designs and fabricates community-scale carbonizer for MSW and AW. It also covers feedstock testing by using MSW and coconut shell waste (CS). Elemental analysis of the products is performed and exhaust gas is analyzed. From the design, the carbonizer consists of a combustion and carbonization chamber. The former generates heat by biomass combustion and delivers to the latter for carbonization process. Flue gas is cleaned by two water scrubbers. The carbonization temperature was about 400 ˚C and the heating rate was about 2.4 ˚C/min. Wet basis yields of char from MSW and CS were 39.2% and 30%, respectively. Carbon contents in the char products of MSW and CS were 83.58% and 37.02%, respectively. Total suspended solid in flue gas was 233 mg/m3 at the oxygen content of 7% condition. This number passes the regulation of flue gas emission. In sum, this research paper provides the idea of open-burning emission reduction by using a community-scale carbonizer.
