PTT is in discussions with NatureWorks and Mitsubishi Chemical Corp to invest in bioplastic plants next year. The cost and production capacity of both facilities are expected to be finalised towards H2-2010.
Mitsubishi is also considering Thailand as a location for a polybutylenes succinate or PLA plant. NatureWorks is considering its second, full-scale polylactic acid (PLA) plant either in Thailand or another location such as Brazil, Malaysia and Singapore. This plant will require an estimated investment of US$300-400 mln for a production capacity of 150,000 tpa. The new plant is targeted to start up in 2014. PTT is likely to take 50% ownership of each plant.
