Built Environment – Smarter Environment (BE-ST) has highlighted the innovative K-Briq, development by Kenoteq, embodies circular economy values. The K-Briq started life as a research project exploring sustainable, traditional construction methods, identifying the many limitations of historical techniques for modern day applications. Kenoteq set out to 'update' these with their goals including reusing valuable recycled materials from construction and demolition waste, reducing carbon emissions and limiting virgin material exploitation.
Kenoteq found that reusing old bricks was prohibitive, so they spent a decade researching and implementing a circular-economy revolution.
The K-Briq is made from over 90% construction and demolition waste. Their manufacturing process requires less than a tenth of the energy used during the production of clay fired bricks while our method also produces less than a tenth of the CO2 emissions during its manufacture.

The brick has a high thermal mass, which retains heat in the winter and keeps buildings cool in the warmer summer months, so heat and air conditioning costs and energy requirements are kept to a minimum.
Completing the circular economy pathway, K-Briqs are manufactured onsite at a waste handling facility, so transport miles are significantly reduced, and the amount of CO2 used in production is further limited. Trucks can collect K-Briqs when they drop off the waste material, ensuring the number of journeys each truck needs to make does not increase; indeed, this is a reduction when compared to traditional bricks and blocks.
Currently, all brick production takes place near clay extraction, as opposed to areas where the bricks are needed most, such as in the South-East of England. We need to bring supply much closer to demand. Through either a licensing or franchising model with waste recycling centres across the country, we plan to produce K-Briqs as close to the point of construction as possible.
Developing greener bricks is just one step towards building a more sustainable industry.
Gabriela Medero, co-founder of Kenoteq and creator of the K-Briq, said: "At Kenoteq, we're laying a strong foundation for more innovation in the future, but others need to follow our lead if we're to make a real impact. We have a demonstration wall and sample boards at BE-ST's Innovation Factory and are about to build a demonstration structure in their yard so we encourage you to come along and view. We are open to collaboration and will be attending BE-ST Fest later this year. We look forward to working with partners across the sector as we strive together as an industry towards net zero goals."
