Regeneration of ABS material by compounding from recycled SAN produced via a solvent-base green recycling process

This project is associated to the creation of a circular economy around styrene-based plastics such as polystyrene, acrylonitrile-styrene copolymer (SAN) and ABS (acrylonitrile-butadiene-styrene) terpolymer. Polystyvert has
developed a technology that transform ABS post-consumer materials that come from electronics, car parts, toys ect. in a recycled SAN (rSAN) of high purity. This solvent-based technology is green and non-destructive using
dissolution and subsequent precipitation technique. ABS has a complex architecture made of SAN as stiff matrix and dispersed polybutadiene rubber particles that provide impact properties. Herein, the present investigation will
tackle the challenge of making ABS from rSAN by means of hot blends with virgin and recycled rubber. In a last stage, the produced rABS formulations would be evaluated in term of cost and sustainability for further
commercialization.
