Mining, Minerals and Metals Experts Describe a New Era of Sustainable Steel and Cement Production

This blog is part two of a two-part series that highlights specific sustainability actions that have taken place across three global Mining, Minerals, and Metals organizations.

Across all industries, companies large and small are actively adopting customer-centric sustainability as a business imperative. The Mining, Minerals, and Metals industries are no exception. Beyond the positive environmental, social, and governance impact that such efforts yield, these companies are being rewarded with long-term economic gain and competitive advantage.

Businesses, concerned citizens, and governments agree that more needs to be done to achieve the Paris Agreement emission limitations of a +1.5°C or lower global temperature rise (above pre-industrial levels). That was the message related to a recent Schneider Electric-sponsored seminar entitled “Sustainability at the Source, Getting it Right from the Start!”, where three global Mining, Minerals, and Metals organizations discussed their ongoing sustainability strategies and actions into practice.

Schneider Electric supports the carbon emissions reduction efforts by providing end-to-end sustainability solutions, enabled via digital transformation; from evolutionary technologies that address energy usage reduction by optimizing energy and operations management, to microgrids and renewables or more revolutionary strategies like circular economy or transformation of traditional processes.

Innovation Enables Low Emissions Steel Making

Tenova is a leading company specialized in sustainable solutions for the green transition of the metals industry. Their over 2,300 engineers, metallurgists, chemists, and experienced consultants across 19 countries have helped companies reduce costs, save energy, and limit environmental impact while improving work conditions by offering innovative technology design and services.

Over recent years, this technology company has emerged as the company with the most sustainable technology portfolio in steel making. When steel is manufactured, blast furnaces typically use a large quantity of cooking coal, which is a significant source of global carbon emissions. In fact, according to their Executive Vice President, coal-fired blast furnaces are responsible for 92% of carbon emissions generated by the steel-making process.

However, over the last several years, innovations have helped to render steel-making operations more sustainable.  In the case of direct reduced iron (DRI) plants, where electric arc furnaces fired by natural gas are being utilized, for example, CO2 emissions are reduced by 50% when compared to traditional blast furnaces that utilize coal.  Approximately 30% of the world’s steel is now manufactured using electrical furnaces, which often use recycled scrap steel as the primary source of furnace feeder materials.
Companies are also working on methods to produce steel with zero emissions. As the steel industry in the near future will be expected to produce nearly two billion tons of steel per year, new plants are being planned and built capable of producing hundreds and thousands of tons of steel per year using CO emissions-free hydrogen. In fact, Tenova is leading the effort in designing the very first hydro reduction plant in China (such plants feature the flexible, incremental utilization of hydrogen, which is capable of reducing CO2 emissions up to 95% across the entire steel production route). Such initiatives are helping industrial regions across the globe to achieve lower emissions faster.

Over the last 10 years, steel itself has also become both stronger and lighter. Lighter vehicles produce much lower emissions and can now be built without undermining the durability and integrity of the vehicle’s structure. Accelerating the development of such materials is another way that a company contributes to overall carbon emissions reductions.

Major Cement Production Company Takes Sustainability to a New Level

As urbanization continues to grow, the opportunity for carbon emissions reduction in the cement and concrete manufacturing sectors is significant.

Today, the world’s cement production generates about 8% of global CO2 emissions, similar to the level of emissions produced by the steel industry. One of the world’s leading cement producers, whose 72,000 employees operate across 80 countries, is keenly aware of its responsibility to increase the sustainability of cement production.

According to their head of environment & public affairs at their Canadian operations, the company has pledged to achieve net-zero carbon emissions by 2030. “Everyone is racing to decarbonize. We are making our contribution by developing the lowest carbon emission concrete and cement products possible,” he said.

Cement production uses high levels of thermal and electric energy to drive the kilns that produce the cement. This cement producer is pursuing ways to both reduce the amount of thermal energy needed and to develop kilns that can substitute alternative fuels for fossil fuels. This “geo-cycle’ approach uses materials such as non-recyclable plastics, textile industry and construction demolition waste, and wood fines (a bio-solid) to substitute for coal, pet coke, and even natural gas. In fact, in their new British Columbia plant, they will be co-processing over 48 million tons of waste and bi-products in their kilns as a source of combustion energy.

“We plan to solidify ourselves as not only a building materials company, but as a waste management company into the future,” he said.
