The launch of SteelPhalt’s carbon-negative asphalt product exemplifies Harsco Corporation’s commitment to environmental solutions in 2022. SteelPhalt is a part of Harsco Corporation’s Harsco Environmental division.
SteelPhalt’s asphalt products use 95 percent 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.
