Coal fly ash recycled into building materials

A green technology company has developed technologies that can turn coal fly ash into building materials.

A green technology company has developed technologies that can turn coal fly ash into building materials.

The company, Vecor, has used technology originally conceived at the University of New South Wales, before being developed further in its laboratories.

Vecor has patented six product applications with 50 to 99 per cent recycled content and aims to provide profitability to otherwise environmentally destructive industrial byproducts.

Vecor Founder and CEO, Alex Koszo, said the company is using the material to manufacture building products suitable for multiple industrial hardware applications, as part of their grey to green vision.

“It is estimated that over 300 million tonnes of the ultra-fine coal fly ash particles are dumped each year, where it may pollute the soil, water and air with harmful elements such as arsenic, mercury and lithium,” Koszo said.

“A great multiple of this tonnage is sitting in lakes and unlined landfills all over the industrialised world, requiring remediation.”

“The innovations underpinning Vecor’s technology span the disciplines of material science, chemistry and industrial hardware.”

Applications include ceramic tiles, refractories, industrial ceramics, fillers for paint and plastics, aggregates and sand.

According to Koszo, in addition to providing a solution to the coal fly ash waste problem, Vecor’s technology promotes sustainability in the highly resource intensive porcelain tile industry.

“The sintering step of Vecor’s process has been independently proven to render all harmful and toxic elements in the fly ash completely and permanently inert,” Koszo said.

“Our product consumes 50 per cent less virgin raw material, 85 per cent less water and 15 per cent less energy compared to the porcelain tile manufacturing process, translating into a significant manufacturing cost advantage.”
