Researchers at Heriot-Watt University in Scotland have developed what they claim is the world’s first brick made from 90% construction and demolition waste.
The K-Briq, which is now being produced commercially by spin-off company Kenoteq, produces a tenth of the CO2 emissions of a traditional fired brick, uses less than a tenth of the energy in its manufacture, and can be made in any colour.
Up to 85% of bricks used in Scotland are currently being imported from England or Europe, which the university said raised questions about the long-term sustainability of the sector.
The Kenoteq team now has an agreement with Hamilton’s Waste & Recycling to produce the K-Briq onsite at its recycling site.
Professor Gabriela Medero, who conceived the idea of the K-Briq more than 10 years ago, said: “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.
“The K-Briq looks like a normal brick, weighs the same and behaves like a clay brick but offers better insulation properties. It is sustainable and not kiln-fired so it is far better for the environment and represents massive savings for the construction industry in terms of related taxes.”
Dr Sam Chapman, who works in close partnership with professor Medero on Kenoteq, added: “Kenoteq has invested in machinery that can produce three million bricks per year. In the past year, we’ve produced thousands of bricks and put them through rigorous testing with the K-Briq now commercially available to construction clients. The Scottish government has set very high targets for housebuilding with 50,000 new homes earmarked for construction in the next three years. We hope Kenoteq will be part of those homes.”

Cost not mentioned ?
Says nothing about how it’s made?
Will there be enough builders waste to sustain this?
the K brick looks a lot like the concrete bricketes we already use for finding floor heights and levelling across lintels when conventional block work doesn’t work. Is the k brick porous ? if so maybe it needs to be used internally as feature walling. It may work on projects with a warmer climate. We did use the concrete bricks on a project for mizen in popular, East London as face work nice effect.
Many Thanks

Nice idea if it works!
Always sceptical of something for nothing.
Only questions for what appears to be missing from the article are:
1. What effect does the binder have on the environment?
2. How long will the brick last for? Is there a guarantee? British Standard? European standard – if we are allowed to export it next week?
3. How like a clay brick does it behave?
4. What load will it carry?
5. How better than a clay brick is the insulation?
6. How long will it maintain its integrity in sunlight? Even Scotland gets some sometimes.
7. How does it behave in fire?
8. How is it cut and what are the health risks?
9. Why are savings for the construction industry qualified by only “related taxes”
