Phetchaburi Biomass, Thailand

The plant where this project is based produces polyester which uses high temperatures during the manufacturing process. Before the implementation of this project, the plant was using approximately 11,000 tonnes of coal a year to power its operations. With the installation of new thermal boilers, the plant avoids emissions from fossil fuels by using a variety of biomass waste to generate power. Being able to use multiple types of biomass in the boilers to produce a stable output above 300ºC makes this technology a first both within Thailand and in the textiles industry.

The biomass used by this project is abundantly available in the surrounding areas and includes rice husk, wood chips, palm and coconut shells. These sources of biomass are by-products of existing agricultural and manufacturing activities and were previously burnt or left in fields to decay.

Beyond the emissions reductions, the project has improved the air quality by substantially reducing pollutants from fossil fuel combustion such as nitrous dioxide (NO2), sulphur dioxide (SO2) and particle matter. Additionally, the project avoids biomass decaying in open fields which prevents the creation of methane, unpleasant odours and dense, stagnant water that can be breeding grounds for disease.

Alongside the environmental benefits, the project has created over 20 temporary, construction jobs and eight permanent, operational roles. It is also providing a new source of income for rural farmers who supply and transport the biomass to the manufacturing plant. The local community is supported by the project owner who is providing voluntary scholarships which develop the local workforce.
