Scientists hoping to reduce the environmental impact of the construction industry have developed a way to grow building materials using knitted molds and the root network of fungi. Although researchers have experimented with similar composites before, the shape and growth constraints of the organic material have made it hard to develop diverse applications that fulfill its potential.

Using the knitted molds as a flexible framework or ‘formwork’, the scientists created a composite called ‘mycocrete’ which is stronger and more versatile in terms of shape and form, allowing the scientists to grow lightweight and relatively eco-friendly construction materials.

“Our ambition is to transform the look, feel and well-being of architectural spaces using mycelium in combination with bio-based materials such as wool, sawdust and cellulose,” said Dr. Jane Scott of Newcastle University, corresponding author of the paper in Frontiers in Bioengineering and Biotechnology. The research was carried out by a team of designers, engineers, and scientists in the Living Textiles Research Group, part of the Hub for Biotechnology in the Built Environment at Newcastle University.
