What Harsco Environmental does

Harsco Environmental is a division of Enviri Corporation (formerly Harsco Corporation) that provides environmental services and resource recovery solutions to integrated steel mills and metal producers globally. Operating at more than 130 sites across 30+ countries with 5,001-10,000 employees and headquarters in London, the company delivers on-site services spanning the full steel production lifecycle — raw material processing, iron and steelmaking, casting and semi-finished handling, and rolling and finished product logistics — through dedicated capabilities in slag management, scrap management (including its proprietary ScrapMaster® system), meltshop and furnace services, materials handling, and resource recovery.

The company generates revenue through long-term service contracts (typically 10-15 years) with enterprise steel mill customers, with fees tied to tonnage processed and specific service delivery at customer facilities. Beyond services, Harsco Environmental operates an ecoproducts™ business that transforms steel mill by-products (slag, dust, sludge, millscale) into sellable materials including asphalt products under the SteelPhalt™ brand (SteelFlow, SteelSuDS, SteelSurf, SteelPave, SteelFlex, SteelPatch), agricultural soil conditioners (AgrowSil™, Agrosilicio™), cement additives (Superfines, Carbicrete), mineral CSA for acid mine drainage remediation, and refractories (Chamotte, Mullite, MAC 90, MAG 85). The company also designs, builds, commissions, and operates metal recovery and slag processing plants under managed-service contracts.

Harsco Environmental traces its heritage to 1853 and was rebranded from Harsco Metals & Minerals in 2019 to reflect its environmental focus. In 2020, Enviri divested its Industrial division, and in 2026, Enviri is completing the sale of its Clean Earth division to Veolia and spinning off Harsco Environmental and Harsco Rail into a new standalone public company called New Enviri (closing expected June 1, 2026). The company reported revenues exceeding $1 billion in 2023 with adjusted EBITDA margins above 18% and won 22 of 23 contracts in the prior year, demonstrating strong customer retention across its enterprise steel-mill base.

Regional players

• Dowa Holdings: Dowa Holdings is a Japanese environmental management and metal recycling company that processes non-ferrous metals, electronic waste, and industrial by-products. While primarily Japan-focused, Dowa competes with Harsco in non-ferrous metal recovery and recycling, particularly in Asian markets.
• Kuusakoski: Kuusakoski is a leading Nordic metal recycling company that processes metal waste into raw materials for industry. While more regionally focused, it competes with Harsco's broader metal recovery activities in Northern Europe and offers comparable recycling and resource recovery services.
• Stena Recycling: Stena Recycling is a major European metal recycling and environmental services company that processes industrial and metal waste into valuable raw materials. It competes with Harsco in metal recovery and resource recovery, particularly in the Nordic and broader European markets.

Broad incumbents

• Commercial Metals Company (CMC): CMC is a vertically integrated steel manufacturer and metals recycler that operates its own scrap collection and processing operations. As both a customer and competitor in the metals recycling value chain, CMC represents a comparable player for Harsco's resource recovery activities.
• Sims Metal Management: Sims Metal is one of the world's largest metal recyclers, with operations spanning scrap collection, processing, and trading. While Sims focuses on scrap metal rather than on-site mill services, it competes with Harsco's metal recovery and resource recovery offerings in the broader recycling value chain.
• Veolia Environmental Services: Veolia is a global environmental services giant that competes in waste management and resource recovery, and is currently acquiring Harsco's Clean Earth division. Veolia's industrial services and hazardous waste capabilities overlap with parts of Harsco Environmental's service portfolio, particularly in industrial waste treatment.
• EMR Group: EMR Group is a major global metal recycler and processor, with broader scrap metal operations that overlap with Harsco's resource recovery capabilities. While EMR focuses on scrap collection and processing rather than on-site mill services, it represents a comparable player in metal recovery from industrial waste streams.
• Radius Recycling (formerly Schnitzer Steel): Radius Recycling is a major North American metal recycler and manufacturer of recycled steel products, with operations overlapping with Harsco's metal recovery services. The company operates metal recycling facilities that process scrap and industrial by-products into finished products.

Direct peers

• Befesa: Befesa is a European-based environmental services company specializing in the recycling of steel dust and salt slags from steel mills, producing valuable by-products.
