This chapter presents how 3D printing biopolymers can enable a circular economy.
- We focus on 3D printing as a technology for distributed production, how the use of biopolymers from second and third-generation biomass such as food waste and algae can ensure that sourcing is regenerative and non-extractive, and the need for comprehensive life-cycle assessment.
- The technical means by which 3D printing can be adapted to and can add functionality to biopolymers is discussed.
- A case study on extracting chitin-cellulose biopolymer formulations from local biomass is provided, offering a view toward regenerative production for a circular economy.
- The future of 3D printing biopolymers for the circular economy is discussed, with an emphasis on improving material performance and developing scalable regenerative supply chains.
