Sand is the second most consumed natural resource in the world behind water.

50 billion tonnes are mined globally every year from rivers, dunes and ocean dredging for use in construction.

Washing sand for use in construction requires massive volumes of water which is expensive to clean up and creates a lot of waste.

The global construction industry has set a goal of achieving zero emissions sustainable concrete by 2050.

Concrete is the world’s most widely used building material. It is strong, versatile, low cost, fire resistance, water resistance and creates structures that last a long time. However, concrete production accounts for at least 8% of the world's carbon emissions.

For construction to be
more sustainable, concrete
must be more sustainable.

For construction to be more sustainable,
concrete must be more sustainable.

The construction industry is booming and needs lots of concrete.

To secure a more environmentally friendly and sustainable construction industry: we need to find alternatives to natural sand in concrete. We need to wash without water, recycle waste and by-products, and use less cement to achieve the same concrete strength.

The secret is in the sand. Kayasand.

CrusherDust to Kayasand

Engineered sand from our Kayasand plants has the potential to save concrete producers 6,000 tonnes of carbon emissions each year.

Our goal is to create the perfect concrete sand. The cuboidal shape, precise grading and consistency of our sand is of such quality when compared with natural sand, it requires up to 20% less cement to create concrete of the same strength.

Plus, our plants turn waste into saleable product, creating a truly circular economy and further reducing the industry's carbon footprint.

Waste glass is recycled into premium concrete sand, concrete is recycled back into concrete, and cement substitutes are created from limestone filler and waste slag.
