This blog is part of our Sustainnovation series.

Sustainnovation is an exhibition (both physical and digital) of some of the most sustainable and innovative products coming onto the market at the moment. Our engineers and designers have carefully selected products that they feel will help us, and the planet, achieve our sustainable goals.


Set to revolutionise the construction sector, the K-Briq® is the world’s most sustainable brick.

It competes technically and financially with a traditional facing brick but offers enhanced sustainability credentials and increased thermal insulation qualities. The K-Briq is made from over 90% local recycled construction and demolition waste, with a square metre of K-Briqs using 126kg of recycled waste. The bricks are unfired which means production uses 90% less energy and the K-Briq has a tenth of the carbon footprint of a traditional clay or concrete brick. Supporting a fully circular process, the K-Briq can be entirely recycled into a new K-Briq, supporting the need to significantly lower the carbon footprint of the built environment.

The product was invented by researchers at Heriot-Watt University, with research and development support from Interface, Scottish Enterprise, BE-ST and The Royal College of Engineering.

Launching later this year, the K-Briq will be available in 10 standard colours with the ability to offer a full bespoke colour palette through the use of recycled pigments to colour the bricks.

K-Briq® samples are currently on display in our Edinburgh office.
