A Study on Applicability of Municipal Solid Waste Incinerator to Hoi an City ~ View Points on Waste Burning Ability and Landfill Waste Reduction ~

Abstract

Hoi An city, an ancient town recognized by UNESCO as the world cultural heritage, received 2.15 million tourists in 2015. The figure is high comparing to the population of 93,000 of Hoi An and increases waste generation amount in the city. All the waste including tourism waste is disposed into landfill directly, making its lifetime shorter and causing serious environment pollution. Our previous study in 2015 identified the generation and compositions of tourism waste from the city center area as well as those of household waste from city center, rural and urban/suburban areas. In this study, the applicability of incineration to the waste of Hoi An is investigated. Specifically, we determine waste chemical elements and ash content by laboratory experiments. As a result, incineration is applicable because heating value of the waste is about 9.3 MJ/kg. Moreover, reduction rate of landfill waste is up to 80% of weight
