Exploring the Plastic Collection and Recycling Trends in Sri Lanka

Abstract

This study examined plastic waste management in Sri Lanka, concentrating on the contributing factors to plastic waste generation and collection. Data were gathered through a questionnaire survey from registered plastic recycling and management centres. The analysis revealed a positive correlation between tourist arrivals and plastic waste generation, indicating increased plastic waste production due to tourism. However, plastic waste collection negatively correlated with precipitation levels, suggesting that heavy rainfall hampers collection efforts. The study found HDPE, PVC, LDPE, and PP to be the most collected and recycled plastic types, whereas PS and PET recycling were less prevalent. The results demonstrate the need for enhanced recycling infra-structure and highlight the necessity for government participation in plastic waste management initiatives. The study recommends increasing waste collection and recycling during the tourist season. As well as, enhancing public and private awareness, there should be additional investment in recycling facilities. The findings offer crucial insights into plastic waste management in Sri Lanka, emphasizing the importance of collaborative efforts and comprehensive strategies to tackle plastic pollution.
