Biomass is an important source of energy in Thailand and is currently the main renewable energy source, accounting for 40% of the renewable
energy used. The Department of Alternative Energy and E�ciency (DEDE), Ministry of Thailand, has been promoting the use of renewable
energy in Thailand for the past decade. The new target for renewable energy usage in the country is set at 25% of the �nal energy demand in
2021. Thailand is the world’s fourth largest producer of cassava and this results in the production of signi�cant amounts of cassava rhizome
which is a waste product. Cassava rhizome has the potential to be co-�red with coal for the production of heat and power. With suitable
co-�ring ratios, little modi�cation will be required in the co-�ring technology. This review article is concerned with an investigation of the
feasibility of co-�ring cassava rhizome in a combined heat and power system for a cassava based bio-ethanol plant in Thailand. Enhanced use
of cassava rhizome for heat and power production could potentially contribute to a reduction of greenhouse gas emissions and costs, and
would help the country to meet the 2021 renewable energy target
