2024
Hemali, N. A. | De Alwis, A. A. P.
The study’s findings serve as a crucial foundation for policymakers, environmentalists, and stakeholders to take necessary actions and develop sustainable waste management strategies tailored to the specific challenges faced in the Western Province of Sri Lanka, contributing to broader global efforts to mitigate the growing waste crisis. It’s a significant concern that the volume of waste is expected to triple by 2050, and the current waste management practices seem insufficient to handle this growth sustainably. The study indicates a per capita waste generation of 0.43 kg in Sri Lanka, with the Western Province at a higher rate of 0.53 kg. This data points to the urgency of addressing waste management practices in this region, especially considering its significance in the country’s GDP. The results also show that the total municipal waste generation in the Western Province is 3248 kg per day whereas the recovery is only 25% (803 kg) in terms of recycling and composting. Burning, burying, and open dumping are highlighted as other prevailing practices for managing waste, which have adverse impacts on the environment and public health. Further research is recommended to identify and address these unaccounted waste streams, especially those at the household level.
