Contribution of waste segregation to GHG emissions, land usage, and health risk of NMVOC exposure: a study in Malaysia

The present study examined greenhouse gas (GHG) emissions, land usage, cost of land use, and health risk exposure to non-methane volatile organic compounds (NMVOC). Waste volume was analysed using the mathematical models obtained from previous literature. The key findings highlighted that the averag...
