isovac® 100 % recyclebar

Our world will be a livable place tomorrow

The question of sustainable conservation of resources can only be whether our world will be a livable place tomorrow. Set a new standard with our innovative isovac® electrical steel and contribute to a more sustainable and environmentally compatible future.


100% recyclability

Our isovac® electrical steel is 100% recyclable. When calculating costs across the entire product lifecycle, steel shows substantial advantages in eco-balance when compared to other materials.

Lowest emissions

Our optimized production processes guarantee the lowest emissions. This reduces the environmental impact and sustainably increases the quality of life for future generations.

Recycled materials

67% of all incurred recycling materials and wastes are returned to the production process. This recycling process requires few natural resources and minimizes waste.

Free from chromium and formaldehyde 

In collaboration with leading European varnish manufacturers, we supply insulating varnishes that contain no toxins, carcinogens, mutagens, formaldehyde or chromium compounds. The coatings meet all applicable EU directives.

Low energy consumption

Intelligent utilization of released energy and optimized selection of process parameters in the production of isovac® leads to substantially lower overall energy consumption than in conventional manufacturing processes.

Most ecological steelmaking plant in the world

We assume holistic responsibility for our products, continually optimize our production processes and develop our environmental management systems. We see environmental protection as the responsibility of each employee.

Sustainable voestalpine premium quality with reduced carbon footprint

Ten percent of the direct carbon emissions at the Linz site are avoided through processoptimized operation in the production of greentec steel. Using a balance model, these saved emissions are allocated to the flat steel products supplied by the voestalpine Steel Division. 

The material and processing properties of the steel are not affected in any way by the carbonreduced production route. Each high-quality voestalpine steel strip product is available with its unique profile of benefits and a reduced carbon footprint. 

Convincing advantages:

  • Reduced specific carbon footprint
  • Reduced Scope 3 emissions at the customer

  • Individually adjusted carbon footprint based on a verified balance model

  • Unchanged range of grades and dimensions in proven voestalpine premium quality.

  • No change in material and processing properties because the chemical analysis and mechanical profiles remain unchanged.

Verification of historical data

  • Data and balance model validated by Lloyd’s Register based on EN-ISO 14064-2
  • Consideration of direct emissions (Scope 1) and indirect emissions (Scope 2 and 3)

Method of calculation

Determination of carbon footprint (cradle to gate)

  • Method pursuant to EN15804 A2, Environmental Product Declaration (EPD)
  • Method pursuant to worldsteel CML 2001-2016

How is the carbon footprint reduced?

  • Production optimized with respect to carbon emissions (blast furnace route)
  • Utilization of green electricity purchased from third parties
