Iskandar Malaysia (IM) is a new economic region in Malaysia’s
most southern state, Johor. The region is targeted for massive development by
2025 with a targeted rapid increase in the population to 3
million, or double the 2005 level, within the 20-year development period. IM
was chosen as the study area of “Low-carbon society for Iskandar Malaysia 2025”
which has an action “Sustainable Waste Management” in 12 countermeasure actions
towards climate resilient urban development for Iskandar Malaysia. In this
paper, we evaluated alternative solid waste management towards the building of
both a sound material society and a low-carbon society. This study covers five
sectors namely management of municipal solid waste, agricultural waste,
industrial waste, sewage sludge, and construction and demolition waste. Our target
is half reduction of landfill waste and half of GHG emitted from waste handling
and treatment. Our result shows that both the target are achievable in 2025
with the reduction of 65%, 79%, 81%, 10%, 69% of waste and reduction as GHG
emission as well, respectively. Targets are achievable under the condition of
high participation and segregation efficiency in 2025.
