“Weed for Feed” Project

In 2025, the Group expanded the “Weed for Feed” project to further intensify environmental management standards within its solar power plants. The focus remains on managing weeds and waste materials within project areas based on Circular Economy principles—transforming the burden of waste disposal into valuable animal feed resources. These resources are delivered to farmers in Lopburi and Ratchaburi provinces to support livestock groups and strengthen a symbiotic ecosystem between the industrial sector and the community.

Each year, weeds within the power plant areas must be managed consistently 2–6 times to ensure worker safety from venomous animals and to prevent fire risks. The Group has developed its management approach, shifting from incineration or off-site disposal to proactive Creating Shared Value (CSV) management as follows: 100% of weeds and wood chips can be managed without open burning, which sustainably reduces greenhouse gas emissions and PM 2.5 dust for surrounding communities. Additionally, it tangibly reduces the burden of waste management fees.

From this project expansion, the Group can reduce total waste management costs by more than 725,700 THB per year. This includes reducing the burden of collection and disposal fees for waste materials according to local ordinances (standard rate of 150 THB per cubic meter), as well as eliminating implicit logistics costs and the total transport of waste out of project areas. Furthermore, the project helps 4 farming households in the surrounding areas immensely reduce their animal feed procurement costs, representing a total economic value passed on to the community of 1,209,527 THB per year. This strengthens livestock careers and builds Social License to Operate for the clean energy power plant operations.

The success of the “Weed for Feed” project expansion reflects the Group’s commitment to concrete ESG business operations, with the goal of upgrading this project into a routine work plan to expand to other projects nationwide focusing on clean energy production alongside resource management for the maximum benefit of all stakeholders.
