Polestar: Biodegradable materials for future strometers-polestar

In October 2021 Polestar and Awareness Artist Thijs Biersteker presented the interactive art installation “We Harvest Wind”. Cooperation, inspired by Polestars LCA report, steered attention to the importance of renewable energies and led to more than innovative art. As part of the project, a new, fully biodegradable corn-biodegradable adhesive was developed, which is to have the potential to be used in the future in Polestar vehicles, so the automaker in a recent communication.

The sculpture “We Harvest Wind” has a diameter of three meters and consists of a series of outer wings that turn around a central spiral. The visitors can control the “wind play” themselves by using large fans and become so aware that the power to effect real changes in their own hands. In the development of the work, the Woven Studio of Beer Steker and the United Kingdom Resident research and development team of Polestar hand in hand.

When selecting the material for the outer wings, the team first examined the use of BCOMP PowerRiS, combined with a panel of natural fibers and polypropylene (NFPP) – the same flax-based composite, which also uses Precept in the Polestar Study. However, most natural fiber products use polypropylene resin based on fossil fuels. The artist has questioned this circumstance with the research and development team of Polestar in the context of cooperation and shared a number of more sustainable, biodegradable resins.

“If you create a work of art that speaks about environmental impact, you have to create something that the environment itself does not affect too much.”- Thijs Biersteker, Artists and Founder Woven Studio

What playfully started as an experiment should influence the vehicle production at Polestar in the future. “The project ‘We Harvest Wind’ enabled Woven Studio and Polestar to bundle their powers and explore new material combinations where biocased polymers are used instead of traditional, fossil fuel-based materials. This cooperation has initiated several initiatives within the Polestar team and underpinned some ongoing studies that we carry out with BCOMP. Now we hope to use a fully bio-based solution with Powerrics and bio-based polypropylene in the future production of Polestar vehicles, “says Ross Kelk, Chief Engineer of Interiors at Polestar UK R&D.

The artist Thijs Biersteker continues: “We made the leaves of the sculpture made of 3D-printed, recycled PET plastic, and the outer wings were made with a structure of flax and a new, environmentally friendly maize base – a material combination during the project developed by Woven Studio and Polestar. We have a composite of flax and polylactic acid (PLA), a biodegradable biopolymer manufactured from corn, developed. The combination of these two materials gives the artwork a really organic feeling.”

The installation has been monitored and documented using a material passport in which the methods used and materials used for later recycling are monitored and documented. Polestar takes concrete measures to achieve a climate-neutral future by promoting the transparency of coverage of CO2 footprint, ethics in the supply chain and traceability of materials.
