Researchers create bio-concrete from weeds and crayfish shells

Central Saint Martins graduates Brigitte Kock and Irene Roca Moracia have collaborated to create concrete-like tiles that give new "economic and ecological" value to invasive species. The material for the tiles, which the researchers refer to as bio-concrete, is made from Japanese knotweed and shells from American signal crayfish. The material can take on a range of different finishes These are among the non-native species that are causing the most ecological and economic damage in the UK. By adding value to them, Kock and Moracia hope to incentivise their removal and help restore local biodiversity. "Invasive species removal and control costs the UK around £1.8 billion annually ," Moracia told Dezeen. "The harvested material is incinerated, buried or trashed. We want to stop this waste. We do not want to create a new industry around this product but to relocate the waste the current system is producing." The project was commissioned by the LVMH group , which counts Dior and Louis Vuitton among its brands, with the aim of developing a sustainable alternative to current building materials that could be used in luxury store interiors. Kock and Moracia decided to target concrete, a major carbon emissions culprit . Rather […]
