Transforming steel slag
into value generation
Sustainable innovation for
the steel industry
Transformando resíduos em oportunidades.
Steel Slag
Waste resulting from steel production.
Considered a worrying environmental liability for steel mills around the world, due to the scarcity of technical and economically viable solutions for its disposal.
Furthermore, its storage requires large areas and a high volume of water for the curing process.
8.5 Million
Every year,
tons of steel slag are generated
by steel mills in Brazil.
It is estimated that around 275 million tons of steel slag are generated annually in the world.
Patent ROLTH
With Rolth's innovative technology for processing steel slag, this waste is transformed into valuable raw materials, gaining new applications in the steel industry, civil construction, infrastructure and agriculture.
Its technology, with an international patent , is protected in Brazil, Argentina, the United States, India and in several European countries, including France, Germany, England, Italy, Switzerland, Spain and the Netherlands.
Product Performance Validation
Rolth products meet the requirements according to standards and tests that evaluate the control of steel slag expansibility, "Los Angeles" abrasion wear and product resistance.

Sustainable solution for the steel industry with full use of waste
Cement represents 8% of global GHG emissions.
Steel production accounts for up to 9% of global GHG emissions and the use of scrap has the potential to reduce the carbon footprint by more than 60%.
Reduction of environmental impact by replacing natural aggregate with Rolth aggregate.
