On Nut Waste-to-Energy Plant Opens, Generates 35 Megawatts

New Sky Energy (Bangkok) Co., Ltd. has launched full operations at its On Nut waste-to-energy environmental plant, handling no less than 1,000 tons of waste daily. The facility showcases Waste-to-Energy technology converting waste into 35 megawatts of electricity, equipped with odor management innovations and environmental control systems. The company plans to open a learning center to share modern waste management processes with government, private sector, and the public, alongside vocational development activities promoting environmental knowledge and supporting community quality of life. This reinforces their commitment to sustainable business growth alongside social and environmental care.

CEO He Ning stated that waste management is a critical challenge for major cities, particularly Bangkok, which generates an average of 10,000 tons of waste daily. Adopting waste-to-energy technology offers an alternative to improve waste management efficiency and create added value by converting waste into electricity.

The On Nut waste-to-energy plant is designed to handle at least 1,000 tons of waste per day, using waste incineration for power generation through a systematically controlled process. Waste enters a closed storage building with a capacity of approximately 24,000 tons, where it is stored for 3-5 days to reduce moisture before cranes feed it into a stoker-type incinerator operating at 850-1,100°C. Heat from combustion produces high-pressure steam to drive a steam turbine and generator, producing approximately 35 megawatts of electricity, maximizing the beneficial use of thermal energy from waste.

A key feature is the odor management and environmental control system. The waste storage uses a closed design with negative pressure technology, maintaining internal air pressure lower than outside so air flows inward rather than escaping. Air from the storage area is drawn into the incinerator for combustion at 850-1,100°C, preventing odor dispersion to surrounding areas.

The plant also employs E-nose (Electronic Nose) technology for odor detection and monitoring. Sensor arrays detect volatile compounds in the air and convert them into digital odor fingerprints, processed with AI to analyze and classify odor characteristics and assess concentration levels in real time. This enables continuous monitoring of odor conditions within the storage area, enhancing environmental management efficiency and reducing potential impact on nearby communities.

The project emphasizes transparency with a control room, laboratory, and real-time emissions display system for tracking and verifying environmental performance, reflecting the importance of combining technology with systematic management and oversight.
