Projects Biomass

Siam Cement Group Biomass to Energy

Objective: This project involves the modification of five cement manufacturing plants, located in various areas in Thailand, to use renewable biomass instead of fossil fuels. This has led to substantial emission reductions as well as other significant environmental and socio-economic benefits.

The Context

Thailand relies heavily on the burning of fossil fuels in cement industries. In addition, cement production is a highly emission-intensive activity: it is estimated to account for 5% of total man-made CO2 emissions globally.

The Project

The five cement plants involved in this project previously burned a mix of coal and lignite in their kilns, a process that produced significant amounts of harmful greenhouse gases. Now, these have been replaced with infrastructure that reduces each plant's dependence on fossil fuels with alternative fuels and biomass residue. These biomass fuels include rice husks, wood-processing residues and other agricultural waste.

The Benefits

The project has created supply chains and manufacturing processes for renewable biomass fuels, increasing their availability for local use. This has led to job-creation as well as the generation of supplementary income for farmers. The project has also funded and implemented a range of social and environmental programs such as health clinics which service the communities in the areas around the cement factories. These include building over 6,500 check dams for upstream forest conservation, providing school scholarships, operating mobile health clinics and supporting the development of small-scale local industries.
