abstract
The tapioca processing industry is considered to be one of the largest food processing industrial sectors
in Thailand. However, the growth of the tapioca starch industry has resulted in heavy water pollution as
it generates large amount of solid waste and wastewater with high organic content. This study explores
the applicability of clean technology options to improve the environmental performance of tapioca
starch-processing plants in Thailand. Eight Tapioca starch plants were selected for an exclusive analysis
of the dynamics of clean technology development and adoption. Proposed options mainly involve water
reduction and energy conservation. These include reuse and recycling of water, technology modification
in the production process, and use of biogas to substitute fuel oil for burners. Implementation of these
proposed alternatives to real companies shows that the reduction of starch loss, and water and fuel cost
savings can be achieved.
