MSW Treatment
� Landfill / open dumps– Number of operating sanitary landfills: 93– Number of landfills that never opened: 8– Number of landfills that have been closed: 6– Number of open dumps: 330 (official)
� Incinerators: 3Phuket: 250 t/d currently extended to 850 t/d– Phuket: 250 t/d currently extended to 850 t/d
� Collection of waste on the country side is difficult� Responsibility of waste management on Thesaban
level leads to small amounts of waste� No enforcement of regulations� Tipping fee very low� Landfills are almost full� Landfills are almost full� Resistance of the informal sector
