Green Concrete? The Potential of Plant-Based Fibres

15 March 2024

It is no surprise that the construction industry, is one of the world’s largest consumers of natural resources, but also produces huge amounts of waste that needs to be recycled.

As a potential solution, high-performance building materials, crafted from building rubble and plant waste have been developed as part of the ReMatBuilt project at the Fraunhofer Institute for Wood Research in Braunschweig, Germany.

This innovative approach, not only promises to make construction more sustainable but also offers a beacon of hope for expedited reconstruction efforts in conflict-ridden regions like Ukraine.

Imagine, recycled concrete fortified with plant-based natural fibres like flax and bolstered by wood chips sourced from forestry waste.

Add to the mix, ash from burnt rice husks, serving as a superior substitute for cement while mitigating carbon dioxide emissions. This amalgamation of nature’s bounty and cutting-edge technology embodies the essence of sustainability.

With the backing of the German Federal Ministry of Education and Research (BMBF) and a relentless commitment to innovation, the ReMatBuilt project is poised to reshape the future of construction materials. The team showcased their groundbreaking materials at the Hannover Messe Preview event in February.

The stage is set for a sustainable revolution in construction—one where waste transforms into opportunity and innovation paves the path to a greener future and we are here for it!
