RE Series Enables Significant Reduction of CO₂ Footprint*

What could a more sustainable future look like? We use alternative raw materials that incorporate renewable resources and in selected sites also energy from renewable sources in the manufacturing process. This is how we develop more sustainable plastics – with a reduced carbon footprint and in line with circular economy principles.

Transforming industries: RE series' impact today

Our more sustainable CQ material solutions are not just a promise for the future – they are already in use today. Select the industry in which you operate and learn more about industrial applications that are already using our more sustainable material solutions to support the circular economy.

* Selected RE grades achieve up to 100% product carbon footprint reduction

CQ portfolio for more intelligent circular solutions

The more sustainable RE product series of Covestro is part of the CQ portfolio of circular intelligent solutions, which contribute to the vision of becoming fully circular: Transforming the industry to achieve climate neutrality and keep raw materials in use. The abbreviation “RE” after the product name stands for “renewable” and represents a major step towards a circular economy – while maintaining quality and performance of conventional polycarbonates.

Unveiling the power of our more sustainable RE product series

If you are looking for engineering plastics with a lower carbon footprint, the RE product series portfolio is just what you need. This RE portfolio offers the same high quality and performance as conventional fossil-based polycarbonates. RE grades with high share (up to 89 %) of attributed renewable certified content via mass balance deliver the lowest carbon footprint. With our RE portfolio, we aim to offer customers more sustainable products via a direct drop-in solution without compromising on quality. Our contribution to the more sustainable use of resources is recognized by relevant eco-labels such as EPEAT. Our RE series, with an attributed renewable certified share, includes our Makrolon® RE, Makroblend® RE, Bayblend® RE, and Apec® RE product brands.

Construction & Architectural

  • Makrolon® RE resins

    Makrolon® RE produced with renewable electricity can significantly reduce CO₂ emissions, as low as zero, from cradle to gate.

Key Benefits

  • Fast Implementation:

    Makrolon® RE is a drop-in solution with no need to modify the production line.

  • Reduced CO₂ footprint:

    Makrolon® RE is produced using renewable electricity with reduced CO₂ emissions at selected locations.

  • High Performance:

    More sustainable Makrolon® RE meets the quality of fossil-based polycarbonates.

  • Bio-circular Attributed Share:

    Our RE polycarbonates use mass balancing to attribute a portion of the product to renewable bio-waste and residues, while maintaining identical production processes and specifications to fossil-based products.

FAQ

We produce our RE series polycarbonates using a mass balance approach with renewable-attributed certified feedstocks. The production processes and specifications are the same as primary fossil-based products, but the feedstocks are traced and mass-balanced to attributed bio-waste and residues, marking a significant step towards sustainability.

Mass balance is a chain-of-custody method that traces materials through value chains, allowing for, in this case, the attribution of renewable feedstocks to selected end products. We implement mass balance according to the ISCC PLUS standard.

We calculate the PCF of the RE series through a partial product life cycle assessment, covering the stages from resource extraction to the factory gate. We follow the ISO 14040/14044 standard methodology, considering biogenic carbon sequestration and using preliminary supply chain data. It does not apply offsetting measures and does not consider any burdens from a product’s first life.

Customers can enjoy several advantages by choosing our RE series. These materials allow for a substantial reduction in their product’s carbon footprint. The RE series materials also come with a sustainability declaration, highlighting the commitment to sustainability and the reduced use of primary fossil-based resources. Moreover, the RE series materials offer the same high performance as standard materials. This means customers won't need to modify existing processes or workflows.

The products from the RE series are as recyclable as conventional fossil-based products. The RE series materials can be recycled through the same processes and workflows as their counterparts made from primary fossil-based raw materials.

Circular feedstocks are derived from the mechanical and/or chemical processing of recyclable materials of non-biological origin. In contrast, bio-circular feedstocks are derived from waste and residues of biological origin. Bio-circular feedstocks do not compete with food production and can enable significant reduction in greenhouse gas emissions.

The capacity for producing the RE grades is the same as the capacity for producing primary fossil-based materials. This means that Covestro can introduce renewable materials into large-scale industry installations today without significant limitations.

Available RE series products can be identified in our Solutions Center (category plastics, tag “CQ renewable attributed”).
