Accelerate to be ready for the transition to a circular economy.

In the context of the transition to a circular economy, the issue of "impact" has entered a new phase. Environmental, economic and social impacts are now intertwined.

The impact investing market is growing rapidly, with a circular economy being a priority for impact investors.

Entrepreneurs in a circular economy create economic, social and environmental value.
