These Unfired Recycled Bricks Are Building a Revolution in Sustainable Construction

These Unfired Recycled Bricks Are Building a Revolution in Sustainable Construction

 

It takes around 15,000 bricks just to build a house. A K-Briq has only 13 percent of the carbon footprint of a regular brick. Kenoteq is a closed-loop circular economy company looking to recycle, reuse, and make new innovative and sustainable building products. K-Briq, their flagship product created during research at Heriot-Watt University, is a construction brick made from 90 percent construction waste. It also sits at only 13 percent of the carbon impact and is fully recyclable back into future K-Briqs. 

 

 

How It’s Made 

K-Briq uses 90% recycled raw materials, including waste ceramics, roof tiles, porcelain toilets, and fireproof clays. These materials would otherwise be sent to landfills where they would release harmful toxins and methane gas – a greenhouse gas 84 times more potent than CO2 over a 20-year timeframe. To make one K-Briq, it takes just 2 kilowatts of energy, while a traditional fired brick requires 60 kilowatts. The manufacturing process also emits 80% less carbon dioxide than firing bricks in a kiln, making them one of the most sustainable construction products on the market today. K-Briq is made using a process called hydroforming which molds the bricks underwater under high pressure without applying any heat, meaning that no energy is required to produce them – making them genuinely zero-carbon. 

 

The Benefits 

K-briq offers many benefits over traditional fired bricks, including being lighter (17% of the weight), more robust (7% higher compressive strength), and more thermally efficient (30% poorer thermal conductivity). As they are made from recycled materials, they are also much cheaper to produce, costing just 60% of what it costs to make fired bricks.  

 

As K-briq are non-toxic, they do not release harmful chemicals or pollutants into the environment. They are 100% recyclable back into future K-Briks – creating a closed-loop product life cycle that is unprecedented in the construction industry. 

The sustainability benefits don’t stop there; as K-briq are so thermally efficient, they can help reduce your energy costs by keeping your home or office cooler in summer and warmer in winter – saving you money on your energy bills!  

Kerran Grieve, Founder & CEO of Kenoteq, said:  “Our ambition has always been to provide an ethical alternative to conventional construction products that don’t cost the earth – quite literally. We’re on a mission to change the way buildings are constructed for future generations, and our ground-breaking technology does just that”  “The embodied carbon in buildings is responsible for 11% of global emissions, so it’s clear that we need to find more sustainable ways of constructing our built environment if we want to stand any chance of reaching net zero by 2050″  “We need to rethink the way we build and move towards using more recycled materials in construction as this will help us close the loop on waste while reducing our impact on the planet.”  

 

Conclusion

With global emissions from buildings accounting for 11 percent of all emissions, it's clear that we need to find more sustainable ways to construct our built environment if we want to stand any chance of reaching net zero by 2050. By producing bricks made from 90 percent recycled construction waste, Kenoteq is helping lead the charge toward more sustainable construction practices that will help preserve our planet for future generations.
