Energy process optimisation

Improving the efficiency of our processes is an effective ways to reduce emissions. By optimising how energy is used across our operations, we can significantly lower CO₂e emissions while maintaining product quality and performance.

1. Regenerative Thermal Oxidation system at Maubeuge

The Regenerative Thermal Oxidation (RTO) system at Maubeuge captures and reuses heat generated during the coating process. Instead of relying solely on natural gas, the system recovers energy from process emissions and feeds it back into production. By replacing conventional gas-fired incineration, this solution reduces fossil fuel consumption and lowers CO₂e emissions. It also improves overall energy efficiency within the coating line. The emission reductions achieved are independently verified and added to the Carbon Bank, demonstrating how process innovation can deliver immediate and measurable impact.

2. Replacement of motor gear sets in the cold mill

Upgrading motor and gear systems in the cold mill improves mechanical efficiency and reduces energy losses during operation. This leads to lower electricity consumption across key production steps. Even relatively targeted upgrades can deliver meaningful reductions when applied to large-scale industrial processes. By improving performance and reducing inefficiencies, the project contributes to reduced emissions. The verified savings are included in the Carbon Bank, reinforcing the cumulative impact of multiple optimisation initiatives.

3. Process optimisation of the tunnel furnace at the Direct Sheet Plant

Optimising the operation of the tunnel furnace at the Direct Sheet Plant focuses on reducing energy use while maintaining process stability. Through improved control and operational adjustments, the furnace operates more efficiently. We have replaced wet rolls with dry rolls in the shuttle. Wet rolls are actively cooled by water, this lowers the temperature which requires additional heating later in the process. By replacing the wet rolls with dry rolls, less natural gas is required for reheating the slabs. These improvements lower overall fuel consumption and reduce associated CO₂e emissions without requiring major infrastructure changes. This makes the project both effective and scalable within existing production environments. The resulting CO₂e savings are captured in the Carbon Bank and made available to support customer decarbonisation goals.

4. High Turbulence Roll Cooling (HTRC) at the Hot Strip Mill

The implementation of High Turbulence Roll Cooling technology optimises cooling efficiency in the finishing mill. The High Turbulence Roll Cooling technology saves energy in various ways: it has improved heat transfer, less water pressure is required and therefore fewer pumps need to be running. The result is a measurable decrease in electricity consumption and associated emissions. The CO₂e savings generated are independently verified and contribute directly to the Carbon Bank, supporting transparent emission reduction claims.

5. Walking Beam Furnace 25 at the Hot Strip Mill

The installation of a new walking beam furnace at the Hot Strip Mill replaces a less efficient pusher furnace and significantly reduces energy consumption. This advanced technology improves heat distribution and minimises energy losses during the reheating of steel slabs. As a result, the project delivers substantial CO₂e emission reductions while supporting stable and high-quality steel production. The verified CO₂e savings are added to the Carbon Bank, where they contribute to declarations that enable customers to reduce their reported Scope 3 emissions.

Alternative energy and fuels

Switching to alternative energy sources is key to reducing reliance on fossil fuels. By integrating lower-CO₂e energy and fuels into our processes, we can significantly reduce emissions while maintaining operational continuity.

6. Deployment of biomethane at the Hot Strip Mill

Biomethane is used as a lower-CO₂e alternative to natural gas in various heating processes. Unlike fossil fuels, biomethane is part of the natural carbon cycle, as the CO₂e released during combustion was previously absorbed from the atmosphere. By replacing natural gas with biomethane, this project directly reduces emissions from energy-intensive operations. The CO₂e released when biomethane is burned originally came from plants and organic matter that recently absorbed CO₂e from the atmosphere. This creates a much more circular carbon cycle and leads to significantly lower greenhouse gas emissions compared to fossil natural gas. The resulting CO₂e savings are recorded in the Carbon Bank, enabling customers to benefit from these reductions in their own sustainability reporting.

7. Procurement of low-carbon zinc

Sourcing zinc with a lower CO₂e footprint reduces emissions embedded in the steel coating process. This approach focuses on improving the upstream carbon intensity of input materials. By selecting lower-CO₂e alternatives within the supply chain, the project contributes to reducing Scope 3 emissions associated with raw materials. This is an important step in extending decarbonisation beyond direct operations. The associated CO₂e savings are captured within the Carbon Bank, supporting a broader value chain approach to emission reductions.

8. Procurement of caustic soda produced with renewable electricity

Caustic soda is an essential input in several steel processing steps. By sourcing caustic soda produced using renewable electricity rather than conventional energy sources, the overall CO₂e intensity of the process is reduced. This project demonstrates how procurement choices can directly influence emissions. It highlights the importance of integrating sustainability into sourcing decisions. TheCO₂e savings achieved are verified and added to the Carbon Bank, contributing to measurable reductions across the value chain.
 

Recycling

Recycling plays a critical role in reducing the need for primary raw materials and lowering overall emissions. By increasing circularity and making better use of existing resources, we can reduce both environmental impact and dependency on virgin inputs.

9. Increasing recycled content in steelmaking

Increasing the use of recycled steel scrap is a key lever in reducing the CO₂e intensity of our steel production. At Tata Steel Nederland, ongoing initiatives focus on increasing the share of external scrap in the steelmaking process, within the Basic Oxygen Steelmaking (BOS) route. This reduces the need for iron ore, which is one of the most carbon‑intensive steps in steel production. By increasing scrap input, the process requires less primary iron production, leading to significant CO₂e emission reductions as less iron ore needs to be produced. Iron ore is produced with coal, and is therefore a process with a very high intensity of CO₂e emissions. . This approach not only lowers emissions, but also supports circularity by retaining the value of steel within the European value chain and avoiding downcycling or export of high‑quality scrap. The CO₂e savings achieved through higher scrap usage are quantified, independently verified, and recorded in the Carbon Bank. These verified reductions contribute directly to the pool of available CO₂e savings, enabling customers to reduce their reported Scope 3 emissions through Zeremis solutions while supporting the transition towards more circular steelmaking.
