Biopolymers: Cement Replacement

Abstract

Given the increasing scarcity of resources, a transition from the traditional linear “make-take-waste” production scenario to a circular model is essential to be able to meet the needs of future generations. In the circular economy concept1 products are designed in such a way that their components fit as nutrients in either the biological cycle – biodegradable after use, recycled, and regrown by nature itself – or the technical cycle of industrial non-renewable materials whose finite stocks need to be secured by high-level recycling.
