B4Plastics BV is an industrial biopolymer architecture and manufacturing company founded in 2014 by Stefaan De Wildeman, based at the IQ-Park campus in Dilsen-Stokkem (Lanklaar), Belgium. The company specializes in the discovery, formulation, pilot synthesis, and industrial scale-up of novel biomaterials built from bio-based building blocks (B4).
Operating two specialized R&D centers alongside an industrial production plant, B4Plastics supplies tailor-made biopolymers with programmable degradation triggers. The company scales polymer synthesis from gram-scale laboratory batches up to 1-kiloton commercial volumes, while also licensing proprietary polymer architectures to multinational chemical and plastic manufacturers.
The company works with international partners such as Henkel, 3M, Covestro, and Formfutura to introduce degradable polymers into technical niches, consumer products, and additive manufacturing filaments.
