Steel Recycling: How it Benefits the Environment
The steel industry plays an imperative role in our infrastructure, but it also significantly impacts the environment. The good news is that recycled steel is increasingly being used in the construction of sustainable buildings, which is a positive step towards a greener and more sustainable future.
Steel is one of the most widely recycled materials in the world, with a recycling rate of over 60%. The benefits of recycling steel are numerous, including the reduction of adverse effects caused by mining and steelmaking. However, steel production is still energy-intensive, and most of that energy comes from non-renewable sources. Steelmaking accounts for about 7-9% of all direct emissions from fossil fuels globally, mostly from coal burning. This poses a challenge for the steel industry in reducing its carbon footprint. Although the concept of "green steel" is gaining traction, the reality is that it is not yet affordable since energy costs make up a significant portion (between 20 and 40%) of the total cost of steel production.
A considerable proportion of the world's steel production, approximately 30%, is derived from electric arc furnaces fed with recycled steel or iron smelted with natural gas and hydrogen. Recycling steel is a crucial step towards reducing the demand for new steel, which is essential for preserving our natural resources. However, it is important to acknowledge that while recycling steel is adequate, more is needed to meet global demand. Therefore, we must focus on producing new steel sustainably. We need to work together to find ways to ensure that our steel production is environmentally friendly while meeting our economic needs.
The development of carbon-free steel using hydrogen energy shows much promise for the future. To achieve this goal, it would be prudent to explore the potential of hydrogen hubs and how they can be utilized in the UK. These hubs could provide a localized industry loop by converting excess renewable energy into green hydrogen. The UK could benefit greatly by producing green steel, especially in the northeast, where wind power is already constrained by up to 7%. These hydrogen hubs could utilize offshore renewables and help bring "green" steel back to historic manufacturing centres like Teesside. It is encouraging to see steps towards a sustainable future; hydrogen energy could be vital in achieving this goal.
The environmental benefits of recycling steel are numerous, such as:
· Using recycled steel conserves natural resources and significantly reduces waste that pollutes the environment.
