Parastruct turns waste into cement-alternative building materials

Parastruct, located in Innsbruck, is innovating new materials resembling cement by utilizing agricultural and mineral waste that is usually incinerated or sent to landfills. These materials, which lie between cement-like substances and geopolymers, may incorporate clinker. Key ingredients include recycled mineral binders derived from fine mineral dust and industrial waste such as steel slag, mixed with wood filler. By varying the ratio of binder to filler, Parastruct produces surfaces that range from wood-like to concrete-like, suitable for construction uses like subfloors and 3D-printed elements. The company aims to license its technology to manufacturers for decentralized production. Supported by the EU Commission through awards and participation in the Techstars Sustainability accelerator, Parastruct seeks to transform waste into valuable building materials, minimizing landfill impact.
