Managing waste

1. Waste Management in Sri Lanka: A Case Study This presentation explores a research study on waste generation and recovery in the Western Province of Sri Lanka, a developing country facing significant challenges in managing its growing waste output.

2. Exploring Waste Generation and Its Impacts

3. Challenges Lack of a unified waste management system. Poor household segregation High reliance on dumping and burning. Environmental and health hazards.

4. The Waste Crisis: A Global Concern Waste Generation Global waste generation is expected to triple by 2050, with developing nations contributing significantly. Sri Lanka's Situation Sri Lanka generates 0.43 kg of waste per capita, with the Western Province at a higher rate of 0.53 kg.

5. Western Province: A Case Study Population The Western Province has a population of 5.8 million, accounting for 27% of Sri Lanka's total population. Economic Significance The province contributes over 42.6% to Sri Lanka's GDP, making it a vital economic hub. Waste Generation The Western Province generates 3248 kg of municipal solid waste per day, highlighting the need for effective waste management practices.

6. Waste Management Practices Recycling Only 25% of waste is recovered through recycling and composting. Open Dumping Open dumping is the predominant waste disposal method, posing environmental and health risks. Burning and Burying Burning and burying waste at the household level are common practices, leading to environmental and health hazards.

7. Material Flow Analysis 1 Household Waste Generation The study analyzes the waste material flow from household generation to final disposal. 2 Collection and Sorting Local authorities collect waste and sort it into different categories. 3 Treatment and Disposal Waste undergoes various treatments, including recycling, composting, and open dumping.

8. Waste Composition and Recovery 62% Organic Waste Organic waste constitutes the largest portion of municipal solid waste in Sri Lanka. 25% Recovery Rate The overall waste recovery rate through recycling and composting is 25%.

9. Recommendations for Sustainable Waste Management 1 Policy Reforms Implementing policies that incentivize recycling and discourage open dumping. 2 Public Awareness Educating the public about the importance of proper waste management. 3 Technological Advancements Investing in technologies that enhance waste sorting, recycling, and composting. 4 Community Engagement Encouraging community participation in waste management initiatives.

10. Conclusion: Towards a Sustainable Future The study highlights the urgent need for a comprehensive and sustainable approach to waste management in Sri Lanka. By addressing the challenges and embracing the opportunities, the country can move towards a cleaner and healthier future for its citizens and the environment.
