Harsco Corp. subsidiary opens two asphalt plants in the U.K.  

Harsco Corp. subsidiary SteelPhalt opened two new asphalt plants in Cardiff, Wales and Rotherham England; the first of their kind in 60 years for the environmental solutions company. 

SteelPhalt, based in Rotherham, manufacturers high performance asphalt products for roadmaking in the U.K. Both of the plants manufacture sustainable asphalt products using 95% recycled aggregates. 

“We are able to provide an innovative approach to quality management of slag by transforming it into a high-quality material that can be used in asphalt products,” said Martin Gray, managing director of SteelPhalt. “Using our technical and operational expertise we have designed products to harness the unique properties of slag to provide asphalt products that are not only reducing the need for quarried aggregate, but also providing a more durable and safer road surface.” 

The new plant in Cardiff will use slag from the surrounding area and is designed to produce more than 330,000 tons of sustainable asphalt products per year. Its counterpart in Rotherham will be located on the same site as SteelPhalt’s existing Rotherham plant and will allow for an increase in service and product. 

“Opening these additional plants offers Harsco another resource for the handling of slag from our steel mill customers while also responding to the ever-increasing demand to be more sustainable and mindful of our impact in everything we do,” said Gray. “SteelPhalt offers a solution that is beneficial for our steel mill customers, asphalt customers and the environment.” 

Harsco was founded in 1853 and has operated in South Central Pennsylvania for more than 165 years.  The company provides environmental solutions for industrial and specialty waste systems and technology for the rail sector. It employs 12,000 people in more than 30 countries. 

Harsco announced in September that it plans to move its Camp Hill headquarters to Philadelphia by January 2023.
