To mark Global Recycling Day, Matthew Wenban-Smith reflects on the history of steel recycling and what it tells us about the transition to a net-zero steel economy in the future.

When it comes to recycling, it is worth taking the long view. For the first few thousand years, iron and steel recycling meant reworking rather than re-melting. The development of the blast furnace around one thousand years ago made it possible to convert steel scrap into liquid metal. And the first commercial Electric Arc Furnace (EAF), capable of using 100% scrap, was built in 1906.

Smaller, less costly to build, and more flexible to operate than blast furnaces, the spread of EAFs through the 20th century was limited only by the availability of scrap and electricity.

In the US, as demand for new steel approached saturation and as the steel in infrastructure and buildings constructed 40 or 50 years previously became available for recovery and recycling, scrap-based EAF production began to replace blast furnace steelmaking, even as the blast furnaces themselves used more scrap. Blast furnace production peaked in 1969, and no new blast furnace has been built in the US since 1980 (Construction Physics, 2023). Today, around 70% of steel in the US is made in EAFs (American Iron and Steel Institute, 2021).

The same pattern of increasing demand, met initially from primary production and then later through a growing reliance on scrap, is now playing itself out in Europe and China, is set to take off in south Asia, and it is to be hoped will roll out across Africa. Steel production globally is projected to peak in the second half of the 21st century, with scrap supply following 30 or 40 years after that.

The growth of scrap-based production has been driven by economics, of course, rather than by any concerns about the climate or greenhouse gas emissions – but that doesn’t make it any less welcome. A tonne of steel made entirely from scrap has around one-fifth of the greenhouse gas emissions of a tonne of steel made from iron ore.

Does that mean we can all relax, and recycle our way out of the climate crisis? Sadly not.

The American Iron and Steel Institute (AISI) estimates that the USA now recycles between 70% and 80% of all of its potentially available scrap (AISI, 2021). The World Steel Association (worldsteel) puts the global recycling rate even higher than that, at around 85% for end-of-life scrap.

Then why, despite these impressive recycling rates, is there currently only enough scrap to meet around one-third of the global demand for steel? The main reason is that scrap availability reflects the level of steel production a generation ago, rather than today. Steel production in 1985 was around 720 million tonnes. Today it is around two billion tonnes. Even without taking account of end-of-life recovery and furnace yield losses there is no way to make those numbers add up.

As demand for steel levels off in the future, a higher proportion of that demand will be met from scrap.  In its ‘Sustainable Development Scenario’, in which the end-of-life recycling rate rises to 90%, the IEA estimates that there would be enough scrap to meet 45% of the demand for steel in 2050 (IEA, 2020). That is something to celebrate. But to put it the other way around, it would mean that 55% of the world’s steel – perhaps 1.2 billion tonnes of it – would still be made directly from iron ore.

To have any chance of limiting climate change to ‘well below 2 degrees’ and at the same time respecting the aspirations of 9 to 10 billion people, two things therefore need to happen. Firstly, the vast majority of primary steel will need to be made using ‘near zero’ emission sources of iron – using hydrogen-based direct reduction iron (DRI), direct electrolysis, biofuels, carbon capture or other new processes. And secondly, the electricity used in steelmaking will need to be generated with near zero emissions, whether it is used to power electric arc furnaces, hydrogen production, or direct electrolysis.

Those are the twin challenges for policy makers, steelmakers and steel users, and they apply across the whole sector.

To meet those challenges, they, and we, need to be able to compare the GHG emissions performance of all steelmaking on a like-for-like basis, whether steel is made from 100% scrap, 100% primary iron, or from any ratio of inputs in between – an approach pioneered in the ResponsibleSteel Production Standard, and recommended by the IEA, German Steel Association and others.

So let’s hear it for the recyclers, but also for the ‘near zero’ power generators, and the ‘near zero’ iron innovators.

And for a successful transition to a net-zero steel economy.

By Matthew Wenban-Smith

In the second half of the twentieth century, women's participation in the global workforce grew remarkably. In the United States, female participation in the workforce surged from around 33% in 1948 to over 50% by the late 1970s (U.S. Bureau of Labor Statistics). Similarly in Europe, countries like France and Germany saw a rise from around 45% in the 1960s to over 60% by the 1980s (OECD, 2021). And in South America, Brazil also witnessed significant progress, with participation growing from approximately 18% in 1960 to 40% in 1980 (World Bank, 2020).  

Despite these advancements, industries like steel, mining, and metals remained predominantly male-dominated. A 2019 broad analysis of 66 global steel, metals, and mining companies revealed that women made up between just 3% and 29% of the workforce (S&P Global). Within the steel industry specifically, women account for only about 15% of the workforce, a figure that has remained largely unchanged over the past decade (World Steel Association, 2020). These figures illustrate the persistent challenges to achieving gender diversity within the steel and metals sectors, underscoring the need for continued progress.

As workplaces evolve and diversity initiatives gain momentum, more women are entering and excelling in traditionally male-dominated sectors. Their contributions are driving innovation, improving workplace culture, and challenging longstanding societal barriers.  

In recognition of International Women’s Day, ResponsibleSteel is spotlighting a few of the women who are driving change across the steel supply chain – celebrating their impact, resilience, and leadership and emphasising the need for greater diversity and inclusion in the metals sector.

JSW Steel has achieved Core Site Certification for its Vijayanagar, Dolvi, Salem and Tararpur sites - the group's first certifications against the ResponsibleSteel International Production Standard.

Over the last four decades, JSW Steel has gone from a single unit to a leading steel producer with operations across India and the US. The company's Vijayanagar site has the largest single-site steelmaking capacity in India, able to produce up to 13 million tonnes per annum. The certification of Vijayanagar along with three other sites means that JSW Steel now has 83% of its steel production in India covered by ResponsibleSteel Core Site Certification.

Jayant Acharya, Joint Managing Director of JSW Steel, commented, "The ResponsibleSteel Certification for our 4 sites is a testament to our unwavering resolve to future proof our business by addressing the emerging global challenges while we transition to a sustainable world. I congratulate the team of ResponsibleSteel, the certification body, the assurance panel, and the entire family of JSW Steel for achieving this milestone.  We are committed to certifying all our steelmaking sites by 2028."

JSW Steel serves customers across the automotive, machinery, construction, and engineering industries. Together, the four sites employ over 13,000 workers and 29,000 contractors.

Annie Heaton, CEO of ResponsibleSteel commented “Congratulations to JSW for achieving these four ResponsibleSteel certifications. By choosing to adopt an international standard which addresses not only emissions but a wide breadth of environmental and social issues, JSW is demonstrating ambition, foresight and leadership as a global industry player. This means being open to external monitoring, being ready to engage on opportunities for improvement with local stakeholders and laying the foundations for a responsible transition to near zero. As the second largest steel producing country globally, India has a real opportunity to emerge at the helm of the industry’s shift to sustainable practices. JSW's certifications mean that today we’re proud to have some 29% of India’s steel capacity certified against the ResponsibleSteel International Production Standard. We look forward to their next steps in deepening this journey.”

In addition to consulting workers and contractors as part of the audit, several external stakeholders were involved in the process. Representatives from local police, government, NGOs, schools, colleges, hospitals and citizen forums were invited to give input to the audit. Stakeholders had the opportunity to discuss the performance of the site in relation to health and safety, training opportunities, environmental issues, and the site's impact on the local community.

Take a look at the certificates and public audit summaries here.

ResponsibleSteel and the Initiative for Responsible Mining Assurance (IRMA) are collaborating on a joint project to better understand the social impacts of the net-zero transition for the steel and mining sectors and how standards can help guide good practice. This project is possible thanks to a grant from the ISEAL Innovations Fund, which is supported by the Swiss State Secretariat for Economic Affairs SECO.

We have asked the two project leads, Haruko Horii, Standards Manager at ResponsibleSteel, and Davidzo Muchawaya, Africa Regional Lead at IRMA, to answer a short Q&A for readers to better understand the project itself.

Q: Haruko, what is the vision for the project?

With this project, we want to understand the social impacts of the transition to net zero and what role standards can play in guiding good practice.

The term ‘just transition’ is used by different people in different ways. We need to determine what this looks like for the mining and steel sectors. What exactly is a just transition? Whose transition are we discussing? Workers, local communities or supply chains? What is the scope of transition? These are some of the questions we need to consider. 

Decarbonisation could have adverse social impacts such as job losses or displacement and significant effects on weakening the economic viability of affected communities. Initial research has shown that communities are facing significant social impacts caused by the transition to low-carbon practices. For instance, thousands of people have lost their jobs as a result of shifting from blast furnace technology to electric arc furnaces. These job losses have in turn impacted the wider community’s economic stability, community identity, and overall well-being. 

These are the types of issues we aim to identify through this project, assessing how voluntary sustainability standards (VSS) can address them, identifying gaps, and outlining steps for future, more detailed work that could lead to larger-scale initiatives. We’ll test our findings by engaging with workers, unions, business leaders, community organisations, and other relevant stakeholders to identify an agreed approach and create practical guidance for players in the mining and steel industry.

Q: Davidzo, what do ResponsibleSteel and IRMA have in common, and why are they collaborating on a just transition?

We believe in the power of collaboration and mutual recognition. This project is just one of many examples of how different voluntary sustainability standards can complement and leverage each other's work. Specifically, ResponsibleSteel leverages the assurance system of standards such as IRMA’s at mine site level, while focusing on the steel production aspects. Importantly, both ResponsibleSteel and IRMA were founded on a multi-stakeholder governance system, which has been recognised as a leading practice both by industry and NGOs. This model is recognised as best practice to ensure transparency, accountability, and inclusivity.

The collaboration specific to a just transition is born out of the necessity to ensure two hard-to-abate sectors, steel and mining, address the realities workers and communities are facing in our changing world as many existing mine and steelmaking sites face adaptation or closure. Given the varying impacts of decarbonisation across regions, IRMA and ResponsibleSteel are uniquely positioned to provide frameworks that apply across these different contexts since they are both standard-setting organisations operating globally. What is more, they are able to consider both decarbonisation and the potential social impacts of the transition at the same time.

Q: How do each of you respectively integrate just transition into your standards?

Haruko: Standards are going to play a critical role in promoting accountability during the transition ensuring they are fair and equitable. Although there is no explicit reference to a just transition in the current ResponsibleSteel International Production Standard, there are some elements to address the transition under Principle 4: Decommissioning and Closure, which requires consultation with key stakeholders to minimise any adverse impacts of site closures. In future, the scope of this principle could be expanded to address issues related to site closures, or the Production Standard could adopt a different approach by providing a just transition framework giving steel producers guidelines and tools to navigate an equitable transition with workers and affected communities. We plan to discuss these approaches with stakeholders in the next phases of the project. Integrating practices into the Production Standard will help ensure the industry’s transition is both environmentally and socially just.

Davidzo: As for the IRMA Standard for Responsible Mining, multiple chapters and requirements articulate what best practices could and should be for mining operations wishing to ensure a just transition for workers and affected communities. A prominent example is the requirement to involve affected communities and stakeholders in the development, design, and implementation of the mine rehabilitation and closure plan. Going beyond minimum transparency, the IRMA Standard outlines a series of requirements dedicated to the adequate estimation and financing of mine closure and post-closure. Research shows that mining operations often leave behind environmental and social liabilities, without taking charge of costs associated with the rehabilitation or appropriate closure of the sites thereby foregoing an adequate transition.

Crucially, the role played by both ResponsibleSteel and IRMA would not be the same without their multi-stakeholder governance systems. Thanks to the decision making process that takes into account private sector players as well as rights holders and labour unions, they can ensure that the voices of all parties are heard and taken into account in an equal way - hopefully adding the “just” element to “transition”.

Q: Davidzo, who is the main audience for this project?

The main audience for this project is workers and labour unions, as workers are most directly affected by the transition. Operators, from mining companies to steelmakers, are also key since, as employers, their actions and decisions will be critical to the social impacts of the transition, alongside national and subnational governments. Local communities impacted by the transition, NGOs that aim to act in their interests and standard-setting organisations are also key stakeholders.

Q: Haruko, is there a specific geographic focus for the project?

While just transition challenges and opportunities vary from country to country and even from site to site, the project is truly global as it strives to bring the complexities of these different realities to light. We aim to engage with stakeholders across different regions during the project to hear about the realities of the transition in different contexts. More information on this to come!
