Forget clay and concrete! The new innovative project up and running at Yorkshire Water's Knostrop waste water treatment works in Leeds is turning incinerated sewage into carbon neutral house bricks.
With our massive emphasis on driving down environmental emissions, the new product devised by Leeds University spin-out company Encos, hopes to reduce the environmental impact of construction by providing an alternative to traditional cement.
How does it work?
It combines ash from incinerated sludge with vegetable-oil-based binders to create the bricks and blocks. These are classed as carbon negative because the plants used to make the vegetable oil have absorbed CO2 from the atmosphere.
