Market Impact

This technological breakthrough offers a sustainable alternative to conventional building materials, potentially reducing carbon footprints in the construction industry. The recyclability and fire-resistant properties of the struvite sawdust composite could create new market opportunities and shift demand away from cement-based products.

Event Summary

Researchers at ETH Zurich and Swiss Federal Laboratories for Materials Science and Technology, led by Ronny Kürsteiner, have developed an innovative process to convert sawdust into a recyclable and environmentally friendly composite material using the mineral struvite. This new material, which is stronger than spruce timber and highly fire-resistant, offers a sustainable alternative to cement-bonded particleboards, which have a poor carbon footprint. The process involves using an enzyme from watermelon seeds to control struvite crystallization, binding sawdust particles. The material can be broken down and its components, including Newberyite (struvite's precursor), recycled. The cost of Struvite, potentially sourced from sewage treatment plants, will determine its adoption in the construction industry. The Polytechnic University of Turin assisted in testing the material's fire retardancy.
