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.
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 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 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.
