Abstract
In Thailand, hazardous waste is becoming a major problem, especially toxic chemicals and heavy metal pollutants discharged from factories. The Industrial Works Department (IWD), which has full responsibility for the control of all factory pollution problems, has initiated a joint hazardous waste treatment programme for handling industrial liquid, sludge and solid hazardous wastes from all factories situated in and around Bangkok and the eastern seaboard region. Four industrial hazardous wastes treatment centres are planned. Secure landfills together with research and development centres will also be provided nearby for the ultimate disposal of the inert-salt sludges. The investment, operation and management of the centres is to be handled by private companies which can generate revenue by charging service fees directly to their customers. Since both governmental and private sectors have no experience in this field, a grant system for a pilot centre has been launched by the Government which has reduced the operating costs by providing land, treatment facilities, infrastructure and secured landfills. The first treatment centre which was officially planned in 1985 was put into operation in July 1988 at Samea Dam, Bangkhuntien District, a western suburb of Bangkok. The construction of all necessary facilities was paid for by the Government. The operation and management of the centre is handled by a private contractor, Siam Control Company (SCC) under a 5-year lease. The users will pay service fees directly to the contractor and the Government will receive a rental and royalty fee from the contractor.
