Green Lagoon Technology is a leading biogas power plant company in Malaysia. Of these four GLT plants, one is located in Trong, Perak, at the Topaz Emas Palm Oil Mill; another in Nibong Tebal, Penang, at the United Oil Palm Oil Mill; the third in Muadzam Shah, Pahang, at the Rompin Palm Oil Mill; and the fourth in Banting, Selangor at the Seri Morib Palm Oil Mill. With a combined installed capacity of 5.5 MW, they generate 37,138 MWh per year.
The plants are made up of an anaerobic pond, cooling pond, bio-digester lagoon, mixing pit, gas treatment area, Biogasclean scrubber, dehumidifier and gas engine.
The biological process of microbial biodegradation release various gases, e.g. methane (CH4), carbon dioxide (CO2), hydrogren sulphide (H2S) and ammonia (NH3). Methane is the main gas which is used as fuel for gas engine to generate electricity.
Currently, electricity produced at GLT plants is exported to the TNB grid. In the future, GLT plans to upgrade the engine capacity of at least one of the plants in order to better respond to energy demands.
The palm oil mills have opted to participate in this renewable energy project in order to affirm their commitment to complying with environmental quality regulations.
