HP, for example, is working with materials partner Arkema to develop bio-based materials made with renewable castor oil and using biomethane to further reduce its carbon footprint. While with Evonik, the company is doubling down on sustainability with the 3D High Reusability PA12. Made using renewable energy during production, the material can help reduce the carbon footprint of commonly used PA12 material by 49% without altering its properties.
