Conference Paper

To achieve regional sustainable development by decoupling waste generation from economic growth in Asian countries, this study identified (1) whether the decoupling of municipal solid waste (MSW) generation from economic growth has occurred; and (2) the relationship between MSW generation and related driving factors, by examining six representative countries for the period 1970-2015 as an example. The logarithmic mean Divisia index technique was used to disassemble MSW generation into four dividing factors: population; economic activity (GDP/population); material intensity (DMC/GDP); and waste rate (MSW generation/DMC). The results show that:
The decoupling situation and the level varied among countries: (1) decoupling of MSW generation from economic growth has not occurred in Viet Nam and Cambodia; (2) the decoupling situation in China shifted from coupling (during 1981-1990) to relative decoupling since 1991; (3) the decoupling situation in Japan shifted from relative decoupling (during 1971-2000) to absolute decoupling since 2001; (4) the decoupling situation in Singapore shifted from absolute decoupling (during 2001-2005) to relative decoupling since 2006; (5) the relative decoupling is shown in Thailand during 2011-2015.
Regarding the relationship between MSW generation and related driving factors, we found that (1) increased economic activity was the main factor driving MSW generation in all study countries and during all study periods; (2) the positive effect of population growth was relatively small but not negligible especially in Singapore; (3) decreased material intensity and waste rate had a negative effect on that of MSW generation, but this varied between study countries and sub-periods.
