PABRIK BIO � SUCCINIC ACID DARI MOLASSES KAPASITAS 10.000 TON/TAHUN

Bio-succinic acid (BSA) or 1,4-butanedioic acid is a chemical compound which is functioned as the main feedstock for plastic manufacturing, bio-degradable plastic production (Polybutylene succinate or PBS). Bio-succinic acid will reduce the dependency of fossil-based resources forthe plastic manufac...
