Ultimately it has become a burning political problem at present. Inefficiency in waste management strategies further aggravate the issues preventing national objective of the clear environment. The main objective of this paper is to discuss the factors that influence technical efficiency of waste management and ways and means to maximize that efficiency under Pilisaru Project funded by Central Environmental Authority in Sri Lanka, The data has collected from the sample size which is represented 22% of currently active compost plants by the stratified random sampling considering all forms of administrative local authorities (LAs). Though several Pilisaru projects have achieved a satisfactory level of expected results. The majority are inefficient due to some reasons. The projects mainly target to produce only organic compost and some biomass power generation but no other alternatives concerned. Segregation of waste for compost production is a prerequisite, however, waste segregation is an unsolvable issue due to the various reasons. Another issue is whether condition which is beyond the control of human effort of the natural process of composting. LA s mainly collects only solid waste and they do not collect liquid waste from the sources of waste generation. Basically, compost production in the Pilisaru compost plants is labour intensive. Therefore, it requires more man power for handling the compost production. Lack of land for the expansion of the compost plants and the ongoing process of composting is time consuming are other barriers. Finally, ongoing compost production system is not the eco-friendly. Compost users do not satisfy and trust with the quality of compost produced by the municipal solid waste and no proper market mechanism and distribution. Labourers and other employers are not satisfied with the benefits they get including salary. The efficient waste management system must ensure to produce all possible product other than organic compost. For this new technology should be introduced. Compost should be promoted among the small scale/ subsistence farmers at first and then in large scale agricultural areas with the proper certification procedure. Municipal waste is hidden treasure on the development of righteous agriculture in Sri Lanka with the application of proper scientific and technical method of waste treatment. Therefore, we recommend establishing "Waste Recycling Centres" with the environmentally recycling system (ERS) such a High Speed Indigenous Microbes Fermentation System (ERS).Item Planning implications of population dynamics of suburban areas: a case study of Colombo metropolitan area in Sri Lanka(International Institute of Population Sciences, Mumbai, India, 2006) Chandrasena, U.A.Item The potential of GIS in planning for rural development: a case study of Hambantota district in Sri Lanka(Hyderabad, India, 2006) Chandrasena, U.A.Item Role of natural capital in rural livelihood strategies: a case study of land use related issues in Hambantota District of Sri Lanka(University of Kelaniya, 2008) Chandrasena, U.A.Item ග‍්‍රාමීය සංවර්ධනය ස`දහා කුඩා පරිමාණ ව්‍යවසාය සංවර්ධනයේ ඇති වැදගත්කම (යටියන්තොට ප‍්‍රාදේශීය ලේකම් කොට්ඨාසයෙන්)(Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2015) Wijesinghe, U.M.; Chandrasena, U.A.Item දියර කිරි නිෂ්පාදන කර්මාන්තය ගෘහස්ථ ආර්ථිකය ශක්තිමත් කිරීමට දක්වන දායකත්වය(Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2015) Ranasinghe, K.H.R.; Chandrasena, U.A.Item වේවැල් කර්මාන්තයේ නව ප‍්‍රවණතා පිළිබඳ භූගෝල විද්‍යාත්මක අධ්‍යයනයක්(Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2015) Hettiarachchi, H.A.S.R.; Chandrasena, U.A.Item සූර්ය පැනල භාවිතයට ඇති විභවතාව හා ග‍්‍රාමීය කුටුම්භ විදුලිබල පරිභෝජනය (රස්නායකපුර ප‍්‍රාදේශීය ලේකම් කොට්ඨාසය ඇසුරින්)(Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2015) Dassanayake, D.R.P.M.; Chandrasena, U.A.
