CAMP HILL, PA (April, 25th, 2022) – Harsco Corporation (NYSE: HSC), a global market leader providing environmental solutions, announced Steelphalt, a part of its Harsco Environmental division has launched a carbon-negative asphalt product.

SteelPhalt’s asphalt products use 95% recycled steel slag. Prior steelphalt asphalt products use bitumen to bind the asphalt.  Bitumen is an oil-based binder product with a significant carbon footprint.

Steelphalt’s new asphalt product, called SteelSurf ECO+, uses Kraft Lignin, a renewable bio-based substance, supplied by GautamZenUK , as an alternative to bitumen dramatically reducing the product’s carbon footprint.

“In our journey to become the world’s most sustainable asphalt supplier, this is a huge step forward,” said Julian Smith, SteelPhalt Strategic Growth Director. “This product is an example of what our team’s collective passion for innovation and sustainability can deliver while making the world a greener place.”


LONDON, UK (Aug, 3rd, 2022) – Steelphalt used the New Pelletized Kraft Lignin BioBinder at the St. Andrews Major School, St Andrew’s Rd, Dinas Powys near Cardiff.

It was possible to add the granulated kraft lignin with aggregates for consistent particle distribution towards the production of the Steelsurf ECO+, the Carbon Negative BioAsphalt. In fact, the Granulated Kraft Lignin was much easier to handle.

“We are happy to see the changing perspective about climate change; SteelPhalt is leading the way in the UK and we are proud to be a part of this eco-evolution,” said Mr. RAY, CEO of Gautam ZEN UK.
