On March 27, 2024, Mr. Palakorn Suwannarat, Privy Councilor, presided over the laying of the headstone and raising of the main pillar ceremony for the 1,000-ton On Nut Waste-to-Energy Power Plant Project. The ceremony was also attended by Ms. Zhang Xiaoxiao, Counselor, Economic and Commercial Office of the Embassy of People's Republic of China in Thailand, Mr.Chatree Watanakhajorn, Deputy Permanent Secretary for the Bangkok Metropolitan Administration (BMA), Dr. Chayanan Pakdeejit, Deputy Permanent Secretary of the Ministry of Natural Resources and Environment, Mr.Siriphan Srikongphlee, Deputy Director-General of the Department of Local Administration, executives and officials of Bangkok Metropolitan Administration, representatives from the public and private sectors, and community leaders. The ceremony took place at the On Nut Waste Disposal Center, Prawet Subdistrict, Prawet District, Bangkok.[1]
The private investor company stated that the project will utilize incineration technology, where waste will be burned under high temperatures of approximately 1,000 ± 50 degrees Celsius, automatically controlled by a computer system. The conditions and duration of waste incineration in the incinerator can be monitored and adjusted to ensure that waste incineration can be controlled at all times and to prevent heat loss. The high-temperature gases generated in the incinerator can be converted to hot air to drive generators for electricity generation.
The gases generated from combustion will be treated with air pollution control equipment, including lime, activated carbon powder, and other substances, to absorb pollutants, so that the emission meets the standard. Leachate will be treated with modern technology for reuse. In addition, the waste incinerated in the incinerator will be reduced to only 15-20% by weight after combustion, and some of the resulting ash can be further utilized.
Benefits of the Project are 1. Reducing odor nuisance caused by waste disposal activities because the incineration system employed is a highly efficient waste management technology that operates in a closed system, 2. Addressing the issue of limited land availability for waste disposal in Bangkok and surrounding provinces 3. Communities and the government sector receive benefits from the by-products that arises from the disposal of solid waste in the form of electrical energy and 4. Reducing environmental impact problems and risks to health due to pollution from improper waste disposal.
