Used frying oil becomes sustainable eco-brick

The homes of the future could be built with bricks obtained from waste oil without the need for mortar. This involves the transformation of waste oil into low-cost waste raw material. Australian researchers carried out this study to find a viable option for bricks used in construction.

These are sustainable materials , replacing concrete, iron and steel which account for more than 15% of CO2 emissions. Science has thus obtained a light but strong polymer. The scholars started with dicyclopentadiene, sulfur and spent canola oil , which is a waste used possibly as an economic raw material. It is abundant and inexpensive, so as to obtain a low-cost finished brick that can then be reused as waste.

Such a building material has another advantage: the bricks are capable of adhering to each other thanks to the chemical bonds between sulfur atoms. Mortar and other adhesives become superfluous. This provides for a greater reduction in the environmental impact , also reducing costs and difficulties in the construction and use of bricks. The resulting brick can only be obtained from waste cooking oil, a mix of sulfur and dicyclopentadiene. Both this and the sulfur are by-products deriving from oil refining.

The mortar is no longer needed to bind them, because there is an amino catalyst . Here you get a sustainable and strong building material that will simplify everything. Now the team is taking steps to market the product, perhaps in a short time they can be found already on sale.
