Sulzer Chemtech has supported B&F PLA in the development of China’s first fully-integrated sugar-to-PLA (polylactic acid) plant located in Bengbu, Anhui Province.
The facility utilises Sulzer’s distillation, crystallisation and polymerisation technologies to produce 30 000 tpy of PLA.
The new facility uses glucose from locally sourced corn to produce lactic acid and PLA of different grades, allowing B&F PLA to support the growing bioplastic market. More precisely, the manufacturer is now able to deliver plant-based polymers with different molecular weights and L(+)/D(-) ratios to provide suitable materials for a wide variety of applications.
Sulzer played a crucial role in the construction of the plant, which was completed in record time. The company designed, engineered and supplied customised mass transfer equipment for the purification of lactide and polymerisation processes. Extensive remote assistance during pre-commissioning, commissioning and start-up was also provided to help B&F PLA begin its operations quickly and smoothly.
The successful completion of this project was enabled by Sulzer’s extensive experience in delivering customised equipment and key processing units for bioplastic manufacturing. In particular, the company develops specialised falling film and static crystallisers, loop and plug-flow reactors, mixers as well as distillation and devolatilisation technologies for plants involved in any stage of sugar-to-PLA processing.
