Inside Covestro's Strategy to Cultivate a Circular Economy
Covestro is a global leader in the production of high-quality polymer materials, serving industries ranging from automotive and construction to electronics and healthcare.
As a manufacturer operating in the chemical and materials sector, Covestro faces unique challenges in balancing sustainability with industrial-scale production.
Its commitment to cultivating a circular economy is central to its long-term strategy, ensuring that resources are utilised efficiently, waste is minimised and environmental impact is reduced.
Embedding circularity into operations
Covestro is taking significant strides to embed circularity into its operations.
One key initiative is the company’s focus on chemical recycling and alternative raw materials.
By developing innovative methods to recycle end-of-life plastics and reintroduce them into production, Covestro aims to close material loops and reduce reliance on fossil-based resources.
In addition to recycling efforts, Covestro is pioneering the use of CO2 as a raw material.
Through its proprietary technology, the company is incorporating carbon dioxide into the production of polyurethane foams, reducing dependence on conventional petrochemicals and transforming waste emissions into valuable products.
This initiative not only contributes to circularity but also demonstrates how industrial emissions can be repurposed to create sustainable materials.
Setting new targets for energy efficiency
With an ambitious goal to boost energy efficiency, Covestro is pushing ahead with its focus on climate neutrality and the circular economy.
By 2030, the company aims to reduce energy consumption per ton of product by 20% compared to 2020 levels.
This reduction equates to approximately 550,000 tons of CO2 emissions, comparable to the annual emissions of a city with around 70,000 inhabitants or the yearly emissions of 180,000 cars.
To achieve this target, Covestro is investing in cutting-edge technology and process optimisation.
A prime example is the newly commissioned reactor at its Dormagen site, which utilises waste heat from production processes to generate steam for further manufacturing steps.
This approach is expected to cut CO2 emissions by up to 22,000 tons annually, highlighting the role of technological innovation in improving energy efficiency.
"Climate-neutral production can only be achieved if we significantly reduce our energy requirements for the manufacture of our products," says Dr. Thorsten Dreier, Chief Technology Officer of Covestro.
"This is because there is currently not enough renewable energy available at affordable prices to even begin to cover demand.
"In addition, as a supplier of standard products, we must always keep our manufacturing costs as low as possible in order to be competitive in the global market."
In view of persistently high energy costs, especially in Germany and Europe, energy reduction is therefore a decisive factor for business success.
Thorsten adds: "We are on the right track and I am confident that we will achieve our sustainability goals. The energy efficiency measures will make an important contribution to this."
Waste management & use of renewables
Covestro’s sustainability strategy extends beyond energy efficiency to its broader factory operations and waste management practices.
The company is implementing closed-loop manufacturing techniques, where production waste is recovered and reintegrated into the supply chain.
At multiple sites, advanced filtration and purification systems are reducing wastewater discharge, while solvent recovery systems are cutting down hazardous waste generation.
Furthermore, Covestro is transitioning towards renewable energy sources to power its operations.
In 2024, the company secured a solar power contract with bp for its Tarragona site in Spain, increasing the share of renewable electricity to 30%.
By 2026, 60% of the electricity at its Antwerp site will come from renewable sources, thanks to a power purchase agreement with RWE.
In the United States, four Covestro sites have been fully powered by renewable electricity since the start of 2025.
Polymer manufacturing & sustainability challenges
A Covestro event to announce the energy efficiency target and the commissioning of the Dormagen energy-saving reactor was attended by guests from politics, business and the energy sector.
These included Oliver Krischer, Minister for the Environment, Nature Conservation and Transport of the State of North Rhine-Westphalia and Dr. Julia Metz, Director of Agora Industrie.
Oliver emphasised in his panel talk with Dr. Julia Metz and Dr. Thorsten Dreier how important energy saving is for a sustainable future of the state - and what role the modernisation of industrial production plays in this.
The modernisation of industrial production must be a sustainable process, driving leaders like Covestro to grapple with the unique sustainability challenges of their vertical.
One of the primary hurdles for manufacturers like Covestro is the complexity of recycling advanced polymers, many of which are designed for durability and performance rather than ease of recyclability.
To address this, Covestro is investing in research to develop new, more recyclable materials and scalable recycling technologies.
Another challenge is the high energy intensity of polymer production.
While Covestro is making significant progress in energy efficiency, the sheer scale of its operations means that achieving climate neutrality by 2035 will require continued innovation and investment in renewable energy.
Despite these challenges, Covestro remains steadfast in its commitment to the circular economy.
By embracing innovative recycling methods, improving energy efficiency and transitioning to renewable power, the company is positioning itself as a sustainability leader in the polymer industry.
