tonnes of waste recovered in 2024

Eramet’s environmental policy is designed to promote a more circular economy that uses primary resources more sparingly, based on three key areas of action:

  • Optimal management of mining resources: The mining industry has a crucial role to play in increasing the efficiency of natural resource use. Firstly, by processing lower-grade ore, which reduces the amount of waste rock. Secondly, by recovering as much material as possible from the mine tailings resulting from ore concentration processes. This makes it possible to extract more resources with virtually no increase in environmental impact.
  • Maximizing the use of recycled materials: Eramet strives to incorporate as many secondary raw materials as possible into its production processes, to minimize the consumption of primary raw materials, and to recover as much of the waste generated by its activities as possible (internally or externally).
  • Participation in industrial and regional ecological initiatives: Wherever possible, Eramet’s industrial sites take part in local industrial ecological initiatives by sharing the heat, energy or fluids produced by their activities, or conversely by using fluids from neighboring plants.

Waste transformed into a resource

Senegal

At the Eramet Grande Côte site, a stream of ilmenite initially viewed as waste has been recovered thanks to a standardization scheme conducted in cooperation with an industrial partner. As a result, a new commercial product, “Ilmenite 56,” has been created and is now sold on the market.

Slag for the construction industry

New-Caledonia

Slag from SLN’s ferronickel production is processed to produce a commercial product called “SLAND.” Exported to the United States to be used in sandblasting, it is also used in the Pacific Islands as backfill material and in construction. SLAND has gained official recognition for its quality, having been approved by New Caledonia’s construction regulatory system (RCNC).

Doubling slag recycling

France

At Dunkirk, Eramet recovers its slag (a by-product of ore smelting) for use in the construction industry. In 2023, the identification of new markets enabled the company to double the amount of slag it recycles, thus demonstrating the potential of this material in terms of the circular economy.

Nothing is wasted, everything is recycled

Norvway

At the Kvinesdal site, Eramet Norway is developing new solutions for recycling silicomanganese slag. Marketed under the name “SiGS” (Silica Green Stone), a by-product of manganese smelting, this product is being manufactured thanks to a pilot granulation plant, commissioned to optimize its future use in industry and construction.

Furnace dust and slag are reintroduced into the production process or sold to other industries, while the heat and gases generated are used to power local facilities and public services.
