Taiwanese researchers come up with a bioreactor that consumes semiconductor manufacturing emissions

3 min read

2 February 2012—A Taiwanese research team says it has demonstrated an efficient biological treatment for water-soluble volatile organic compounds (VOCs) emitted from semiconductor and optoelectronic manufacturing processes. This development could offer a more environmentally benign and less costly alternative to today’s expensive methods.

According to the team leader, Ching-Ping Tseng, a professor of biological science and technology at National Chiao Tung University, based in Hsinchu, major pollutants in waste gases emitted from semiconductor manufacturing include water-soluble VOCs, such as acetone, isopropyl alcohol (IPA), and propylene glycol monomethyl ether acetate.
