The production of tapioca starch is an important economic
sector in several countries in Southeast Asia.
About 15 m3 of wastewater highly loaded with organic
compounds is produced per tonne of starch during the
industrial extraction process. Cyanide as a toxic species is
also found, because cyanoglucosides from tapioca roots
are released during the production process that rapidly
decay to cyanide after enzymatic hydrolysis
