Bio PBS, based on two new bio monomers, was supposed to be fully commercial by now. PBS is a low molecular weight, biodegradable polyester, which decomposes completely into CO<sub>2<\/sub> and water and is often compared to LDPE or PP. It\u2019s already made commercially from 50\/50 petro-based succinic acid and 1,4 butanediol, but the petro route is expensive, so growth is limited.<\/p>\n<p>The bio version is off to a slow start because no one so far has built large scale fermenters for the bio monomers. Five production partnerships were set up 6-8 years ago to ferment bio succinic acid and\/or bio BDO, but so far they have built only semi-works plants. Three operate fermenters with combined capacity of only 74 million lb\/year of bio succinic acid. A fourth fermenter starts next year with capacity for another 60 million lb\/year of bio succinic acid, the biggest so far. A fifth company has technology to ferment bio BDO directly and has licensed it to two large chemical companies, which have done full-scale trials, but neither is in production. Bio BDO can also be made by purifying bio succinic acid.<\/p>\n<p>Several Japanese and Korean companies have made small amounts of petro PBS for years. Showa Denko K.K., Tokyo, commercialized Bionolle in the 1990s, developing automotive compounds. Mitsubishi Chemical Corp., Tokyo, introduced GS Pla in 2003 for biodegradable agricultural sheet and film and automotive compounds. IRe Chemical Ltd., Seoul, makes EnPol for biodegradable fish nets; and SK Chemicals Co. Ltd., Gyeonggi-do, makes Skygreen.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By Jan H.
