Description

Waste Types and Classification: Discussed municipal, industrial, hazardous, and electronic waste, emphasizing their environmental and health risks. Current Trends: Highlighted Sri Lanka’s daily waste generation of 6,000–7,000 metric tons, of which only 60% is collected, stressing the urgent need for improvement. Challenges: Identified improper segregation, inadequate recycling infrastructure, and environmental consequences such as pollution and biodiversity loss. Solutions: Advocated for waste reduction, source segregation, composting, recycling, biogas production, and thermochemical energy conversion as sustainable management strategies. Technological and Policy Frameworks: Encouraged adopting modern technologies like incineration and gasification alongside policies supporting recycling and circular economy practices. Community Role: Emphasized public participation and local action plans to foster sustainable waste management at all levels. The session highlighted the critical need for sustainable waste management to combat environmental, economic, and health challenges. The improper disposal of waste contributes to water and soil pollution, greenhouse gas emissions, and health hazards like disease outbreaks. By advocating for recycling, composting, and waste-to-energy technologies, the speaker illustrated how effective waste management can reduce landfill dependency, mitigate climate change, and promote social and economic benefits. These solutions empower communities, preserve resources, and align with Sri Lanka's sustainable development goals.
