Industrial and Mining Decarbonization

The objective of achieving net-zero emissions by 2050 implies structural changes in energy consumption. This is especially true in the industrial sector in Québec, where more than 778 PJ were consumed in 2019. The steel industry and the iron ore mining and pellet sector account for more than 9% of energy consumption and greenhouse gas emissions in Québec's industrial sector. With a decarbonized electricity grid, access to bioenergy and a large portfolio of activities in the iron and steel value chain, the Québec industry has the potential to achieve net-zero emissions. Decarbonizing the entire steel production value chain can be achieved through a combination of technologies that includes energy efficiency, flexible electrification, and the strategic use of bioenergy coupled with carbon capture and storage (BECCS). Successful decarbonization also depends on arbitration and consideration of the various trajectories of decarbonization and process change that can be implemented in Québec's industry. This presentation aims to clarify this decision-making process and offer suggestions as to the best choices for achieving decarbonization in this sector.

Decarbonisation in industry is a major challenge for reducing the carbon footprint. This shift towards greener mining and industrial practices is essential not only to meet environmental requirements but also to ensure the long-term economic and social viability of the industry. This session will present concrete examples from the mining and metallurgical industry for reducing the carbon footprint.

Magnesium oxide production is primarily derived from the calcination of magnesite and can emit significant amounts of CO₂ into the atmosphere. This conference will provide a broad overview of opportunities to reduce the industry’s carbon footprint by comparing alternative and emerging processes and different raw material sources.

As part of its strategy to reduce greenhouse gases, Elkem plans to replace 40% of the fossil coal currently used in its manufacturing processes. To achieve this, Elkem has commissioned a technology demonstration plant for biocarbon production and an R&D centre in Canada.
