Pimalai Resort

The Pimalai Biogas Plant is one of the latest initiatives in addressing food waste issues at the property. The resort team has learned the details of biogas processing from Mr. Kosol Saengthong who operates a successful local biogas plant in Phetchaburi province. In January 2019, the biogas unit arrived at Pimalai and is situated next to the staff canteen. It is a large polyester sack that resembles a big balloon and used to contain methane gas. About 200 kg of kitchen food scraps per day will be emptied into the sack. The scraps will ferment naturally and produce methane gas which will be utilized as a fuel in the staff canteen kitchen. Approximately half of the lower part of the biogas unit, a 50 cubic meter cylinder shaped sack, is secured underground. Cow dung and water are fed into the unit to initiate the fermentation process and the subsequent release of methane gas. Once in operation, pressurized methane gas will lower energy costs used by the kitchen and also reduce the amount of methane that escapes to the atmosphere by the normal decomposition of food waste. It is a win-win situation.
