Camp Hill Pennsylvania US headquartered global leader for environmental solutions for industrial & specialty waste streams Harsco Corporation, in recognition of World Environment Day, announced its continued commitment to improving sustainability & protecting environment through beneficial reuse on 5 June 2022. Harsco Corporation Chairman & CEO Mr Nick Grasberger said “Our corporate vision is to be a global leader of environmental solutions by solving today’s biggest waste challenges. The accomplishments of Clean Earth and Harsco Environmental further support our pursuit of this goal every day and our path towards providing customers with more sustainable solutions, giving purpose to Harsco’s present and defining our future.”The launch of SteelPhalt’s carbon-negative asphalt products, a part of Harsco Corporation’s Harsco Environmental division, exemplifies Harsco Corporation’s commitment to environmental solutions in 2022. SteelPhalt’s asphalt products use 95% recycled steel slag along with bitumen. Conventional asphalt products use bitumen, an oil-based product with a significant carbon footprint, to bind the asphalt. However, the business recently launched a new product that is carbon negative. Called SteelSurf ECO+, the new product uses Kraft lignin-based Lineo, which is a renewable bio-based substance, to replace a portion of bitumen as the product’s binder. Lignin comes from trees and is supplied by GautamZenUK in collaboration with Stora Enso.SteelSurfECO+ is also produced at reduced mixing temperatures compared to traditional asphalt. This reduced mixing temperature means that the amount of energy required to manufacture the product is lower. Ultimately, SteelSurf ECO+ is a carbon-negative asphalt product that delivers customers the skid resistance and durability that they expect. The new ECO+ range of products helps further reduce an industry leading low carbon footprint product range, that was already more sustainable than traditional asphalt due to the beneficial reuse of steel slag.Since 1974, the United Nations has designated June 5 as World Environment Day to engage governments, businesses and citizens in an effort to address pressing environmental issues.
