Changing the carbon game

12 October, 2022

We are changing the way carbon products are used in scrap-based steel production – and since 2019 we are doing it with our friends at Envigas. Through foaming, reduction and carbonization we are able to reduce the use of fossil coal in metallurgy significantly. Mainly by utilizing residues from the forest industry as the raw material.

High level of carbon – low level of pollutants

Envigas produces biocarbon for metallurgical purposes, something that affects the choice of raw materials as well as how the pyrolysis process is planned. Pyrolysis, or dry distillation, is a process that removes both water and the majority of the volatile organic components through high temperature heating. The result is a biocarbon that not only consists of more than 90% carbon, but also smaller amounts of bio-oil and syngas. The high carbon content and low level of other pollutants, makes it possible to replace parts of other established fossil coals, such as anthracite and pet coke.

As scrap is becoming the new ore, the world needs a solution that ensures all residues are taken care of in the best possible way.

Some residues are more difficult to find benefits for, than others. But in order to reduce the need for virgin raw materials, Eramet teamed up with us to find a greener solution for their ferroalloy production.
