BASF has announced that Kunststoffwerk AG Buchs, a subsidiary of Wiha Werkzeuge GmbH, has become the first customer to use its new Mass Balance PA for the serial production of one of its products. BASF sees what it is calling the "mass balance" approach as a means to save fossil raw materials and reduce greenhouse gas emissions, which in turn contributes to sustainable development.
Developed in collaboration with TÜV SÜD (a third-party certification body), this approach allows for the use of renewable feedstocks in its integrated production processes. Biomass - for instance, in the form of biogas or bio-naphtha from certified sustainable production - is used as a feedstock in place of fossil resources at the beginning of the value chain, i.e. in the manufacturing of basic products in existing production plants. "As with their petrochemical analogs, they are fed into plants at the beginning of the production process: bio-naphtha into the steam cracker and biogas into the syngas plant," said Lars Börger, new business development in the performance materials division. This biomass content is then allocated to the different products according to their recipes using the new certified methodology. Up to 100% of the fossil raw materials can be replaced in the end product, which can be marketed accordingly. The quality of the products remains unchanged.
