Sam Chapman: Kenoteq bricksThe construction industry sends millions of tonnes of waste to landfill each year, at significant cost to the industry and the environment. And new legislation requires that by 2025  at least 70% of all waste must be recycled.

These two factors are driving the construction industry to find alternative building methods and materials that reduce waste.

With help from the Innovation Fund of Zero-Waste Scotland, Sam founded the clean tech spin-out company Kenoteq to address this need.

Kenoteq has developed a patent-pending process using traditional earth-construction methods to make unfired bricks that do not use cement which have 90% of their content recycled from building and construction waste. Its unique production process and materials are classified as recyclable by the Scottish Environment Protection Agency.

As the new brick does not use gas firing, large manufacturers can eliminate the cost of gas-fired production and avoid additional carbon taxes under the EU Emissions Trading Scheme (EU ETS). The bricks offer a high thermal mass and are ‘breathable bricks’, reducing the need for air conditioning and air quality controls inside buildings by providing relative humidity buffering.
