Abstract
Wast Management plan and promotion of public participation in Galle, Sri Lanka
Abstract
Galle, a rapidly urbanizing city in Sri Lanka, faces critical challenges in managing solid waste, particularly plastic waste, due to limited resources, inadequate infrastructure, and inefficient waste collection systems. This study aimed to audit the garbage collected within the Galle Municipal Council (GMC) area and implement effective waste management practices. Using simple random sampling and interviews, 2,564 samples were analyzed and classified into residential, commercial, industrial, and service categories. The findings revealed that daily waste collection amounts to 68,377 kg, with contributions from residential areas (52,376 kg), commercial sectors (11,145 kg), industries (2,600 kg), and service sectors (2,256 kg). GIS mapping was employed to identify waste hotspot areas, leading to targeted interventions such as installing CCTV systems to monitor illegal plastic disposal, enforcing regulations, and implementing waste reduction strategies. Notable initiatives included converting organic waste into fertilizers using the Bokashi bin method, reducing waste generation in informal settlements, and decreasing garbage collection frequencies to optimize resources. These measures fostered community participation and provided economic benefits while contributing to the overall environmental health of Galle. This study highlights the importance of comprehensive data collection, innovative practices, and community engagement in developing sustainable waste management solutions.
