According to IDTechEx,  more 3D printing materials suppliers and companies are releasing polymers for 3D printing with green characteristics, like recyclability and reusability; this trend came into full force in 2021 as a different approach to sustainability in 3D Printing.

As an example, IDTexhEx noted that chemical company Braskem teamed up with materials recycling company Vartega to create a polypropylene filament that includes 100% recycled carbon fiber. This filament release is part of a novel carbon fiber filament recycling program that Braskem and Vartega are launching, which will encourage users of these filaments to appropriately recycle them.
