Item Analysis of existing municipal solid waste management practices: A case study in Kelaniya Pradeshiya Sabha area(Department of Zoology and Environmental Management, University of Kelaniya, Sri Lanka, 2017) Senanayake, M.W.P.N.S.; Sewwandi, M.K.V.N.; Showmika, R.; Thilini, P.G.I.; Ubhayawardhana, W.S.M.T.; Yatawara, M.D.M.D.W.M.M.K.A significant amount of solid waste has become a pressing issue with rising population, urbanization, economic activities and consumerism, especially in urban and sub-urban areas creating negative impacts on both environment and human health. Lack of infrastructure and financial resources, poor public participation in waste management process and less enthusiasm of government representatives have also been contributed to complicate the situation. Personal experience and literature revealed that existing SWM systems established in most local authorities are not properly functioned. Therefore, significant gaps are visible in solid waste management process in different local authorities. The present study was planned to explore municipal solid waste management system in Kelaniya Pradeshiya Sabha (KPS), as a key area in Gampaha district to identify best practices and gaps. Data were collected through interviews and questionnaire survey from three categories (officers in KPS, sanitary employees in KPS and general public in KPS area). Descriptive statistics were used to analyse data. Results revealed that waste reduction and capacity building were priority areas in KPS. Though the institutional capacity has been developed to certain extent in KPS, further attention is needed to overcome existing issues. Implementing new policies is further suggested to overcome some existing obstacles. However, the outcome of the study is a framework developed for best practices of solid waste management which can be used at local authorities for effective and efficient municipal solid waste management.Item E-Waste management in selected institutions in Colombo and Gampaha Districts(Department of Zoology and Environmental Management, University of Kelaniya, Sri Lanka, 2017) Athukorala, S.M.W.; Handapangoda, H.M.A.K.; Yatawara, M.D.M.D.W.M.M.K.Electrical and electronic waste (e-waste) is one of the most rapidly growing environmental problems in the world including Sri Lanka. This preliminary study was carried out to identify the attempts of e-waste management in selected institutions in Colombo and Gampaha districts. A questionnaire survey followed by interviews was carried out among randomly selected 20 institutions in Colombo and Gampaha districts. Descriptive statistical methods were used to analyze data. Results revealed that about 55% of respondents reuse their e-waste and 15% of respondents continue recycling the discarded e-waste. Most respondents (95%) has knowledge on e-waste and the effects of unsafe disposal. In addition, 60% of respondents were not aware of any projects or activities on e-waste management by government and local authorities. However, most of the types of electronic devices that are used by these institutions were more or less similar. Further, the survey revealed that the respondents showed willingness to contribute to e-waste management and willingness to pay or willingness to accept for a green product which will not harm the health of human and the environment. The study suggests to conduct proper awareness programmes to the employees in the institutions on handing over, disposal and management of e-waste. In addition, proper monitoring programmes of recycling or disposal is utmost important as e-waste contains a substantial amount of valuable recyclable materials and has potential to become a lucrative business in the country.Item Use of effective microorganisms for rapid composting of mixed garden waste and kitchen waste in windrows at University of Kelaniya(Department of Zoology and Environmental Management, University of Kelaniya, 2015) Yapa, Y.M.H.S.; Amasha, K.G.E.; Chandrasekara, M.M.; Suhaina, M.S.F.; Yatawara, M.D.M.D.W.M.M.K.Item Comparison of the efficiency of the selected compost bins in composting of kitchen and mixed garden waste(Department of Zoology and Environmental Management, University of Kelaniya, 2015) Thangavelu, A.; Udayangani, H.A.S.; Wijerathne, T.M.; Fazal, A.G.M.; Yatawara, M.D.M.D.W.M.M.K.Item Assessment of the composition of the beach litter: a case study n two beaches in Sri Lanka(Department of Zoology and Environmental Management, University of Kelaniya, 2015) Priyadarshani, S.P.I.; Pushpadayana, B.; Surakshi, W.A.G.N.; Weerasinghe, S.D.N.A.M.A.M.; Yatawara, M.D.M.D.W.M.M.K.Item Public participation in solid waste management in Kolonnawa urban council in the western province in Sri Lanka(Department of Zoology and Environmental Management, University of Kelaniya, 2015) Kodituwakku, K.A.R.K.; Yatawara, M.D.M.D.W.M.M.K.
