    The highest percentage (80%) of organic waste generation was recorded in Sri Lanka compared to the other Asian region countries with higher moisture content and low calorific value (Waste Management Outlook, 2017). Total waste generation in the country is about 8,700 Tons/Day and from that 4,480 Tons of waste has been collecting per day (NSWMSC,2019). Considering the waste composition and prevailing socioeconomic parameters, composting can be considered as a most convenient technology that can be applied for organic waste having high moisture content. Pilisaru National Solid Waste Management project has been initiated as a long term solution for solid waste management in the country towards zero waste in 2030. Considering the necessity and suitability, Pilisaru Project provides financial and technical assistance to the requested local authorities in the country to initiate compost projects and other requirements to manage solid waste in a sustainable manner. According to the Pilisaru data, majority of compost plants are in operational stage (83%) and 17% of sites are not in operational states either those sites were totally ended or inactive due to many reasons. The cumulative financial progress of the Pilisaru project is Rs. 2629.74 Million by 31.12.2018. Compost yards implemented under the Pilisaru Project produce about 386 Tons/month of compost and it is about 67% of the total designed capacity. This study aims to evaluate the performance of projects implemented by Pilisaru National Solid Waste Management Project in Southern and Western part of Sri Lanka based on analyzing data and information through field visits, questionnaire survey, formal and informal discussion and expert interviews. According to the findings sites were failed due to poor waste management such as inadequate financial assistance and technical expertise in waste management, failures in site selection and design considerations, low institutional commitment and community involvement, produced compost in poor quality and no regular monitoring of composting process and quality of produced compost etc. Furthermore, gaps identified by analyzing existing solid waste management practices conducted by the local authorities at a significant level and this study proposed practices that can be used by local authorities to rectify the identified gaps. Therefore, best practices in solid waste management need to be practiced further to overcome issues related to waste management in the country. This revealed that out of 20 selected sites, 07 sits show over 75% performance level, 08 sites show 75% - 50% performance level and only 5 sites show below 50% lower performance level.
