K-Briq: An eco-friendly building brick made from 90% recycled construction and demolition waste

Scottish startup Kenoteq has developed an eco-friendly brick, the K-Briq, made up of 90% recycled construction and demolition waste.

A team of engineers from Heriot-Watt University in Scotland created the K-Briq which produces only one tenth the carbon emissions of typical bricks.

Regular bricks use up a number of natural resources and require a lot of heat to be shaped and made. Kilns are typically used when making bricks and these require fossil fuels to heat up to their high operating temperatures – all of which likely adds to the issue of climate change.

However, new technology developed by civil engineer and professor of Geotechnical and Geoenvironmental Engineering at Heriot-Watt University, Gabriela Medero, means the eco-friendly bricks don’t require firing.

The K-Briq, which can be produced in any colour, looks like a normal brick, weighs the same and behaves like a clay brick, but offers better insulation properties.

The eco-friendly brick is the result of 10 years of research and development. Gabriela Medero told Dezeen: “I have spent many years researching building materials and have been concerned that modern construction techniques exploit raw materials without considering that they are amongst the largest contributors to carbon emissions. The amount of waste they produce is not sustainable long-term.”

Kenoteq is producing its bricks on-site at Hamilton’s Waste and Recycling in Edinburgh, minimising the amount of transport required in the process.

The recycled bricks will be used to build 2020’s Serpentine Pavilion, which will centre on the experiences of London’s migrant communities.
