Greentown Labs Circularity Challenge

Thank you for your interest in the Circularity Challenge. In March 2020, the Circularity Challenge concluded. If you are interested in learning more and watching a video about this accelerator program, please click here.

The Greentown Labs Circularity Challenge is a six-month accelerator program for start-ups developed in partnership with BASF, one of the world’s leading chemical companies. The program intends to advance innovative ideas to disrupt the plastics, energy storage and recycling value chains to enable a circular economy.

Believing that disruptive solutions for circular economy must be jointly addressed along the value chain, this program is supported by Stanley Black & Decker, a leading global diversified industrial and member of BASF’s value chain that shares the vision for a more sustainable future.

Why a Circularity Challenge? 

Circular economy is much more than waste management. The aim is to close cycles and use products and resources in the best way possible across the entire value chain. The circular economy model has been gaining ground in politics, industry and society over the last years. Behind this idea is a shift away from the linear model of “take-make-dispose" to a system of closed loops powered by renewable energy. The chemical industry and its innovations can lead the way in this change. BASF is already applying circular economy in a number of ways.


Circular economy thinking, however, cannot be restricted to a company’s own operations. We are looking for start-ups, with a proof of concept solution, that creatively enable circularity for plastics or battery materials or provide digital tools for circularity in general.
