THE FIRST plant pioneering a breakthrough process developed by Sulzer Chemtech for making polylactic acid (PLA) is operating in Etten-Leur, The Netherlands. Synbra Technology successfully put the 5,000-mt/yr plant (Figure 1) into service in 2011. Since then, Sulzer has started up a second plant (Figure 2) for its own use. The 1,000-mt/ yr facility, located in Pfaffikon, Switzerland, is expected to produce high-quality PLA samples by the end of this year.
