Zurich, Switzerland — We are excited to share a striking new time-lapse video capturing four weeks of construction at our first specialized facility in Solothurn, condensed into just 15 seconds.

The video highlights the speed and scale of progress achieved on-site, showing how quickly the project has developed when planning, engineering, and teamwork come together. It offers a clear and compelling view of the effort behind building a cutting-edge recycling facility and marks an important milestone on our journey toward full operation.

This time-lapse is a quick but powerful glimpse behind the scenes — the perfect way to see how much can be accomplished in a short time.

About Grensol 
Founded in 2021, Grensol is an innovative recycling company committed to addressing the challenge of recovering valuable materials from highly complex waste streams. Grensol has developed a novel three-step process for extracting metals, minerals, and polymers from automotive shredder residues (ASR), reprocessing them into circular raw material inputs. The company’s first specialised facility is now operational in Solothurn.
In collaboration with research partners HEIG-VD, ETH Zurich and Worcester Polytechnic Institute, Grensol continues to push the boundaries of materials separation technology for waste that is currently incinerated or landfilled, while actively exploring new industry partnerships and expanding use cases for its platform — advancing a future where even today’s most difficult waste can be transformed into valuable resources. 
Grensol is supported by Innosuisse, the Swiss Federal Office of Environment, the Swiss Climate Foundation, the City of Zurich and BlueLion through their KlimUp programme, the Foundation of Swiss Auto Recyclers, Venture Kick, EPFL Innovation Park’s Tech4Regen accelerator, Impact Hub’s Circular Economy Transition incubator, and the W.A. de Vigier Foundation.
