The general theme for the Forum was ‘Closing Loops – Transitions at Work’. On Monday February 25, Didier explored the WRF. He attended keynotes on sustainable solutions for environmental and other global issues and was also a spectator in for example Recupel's closing the e-loop challenge, where students attempted to design sustainable solutions for the growing e-waste problem. 

WRF 2019 wanted to focus on hands-on sharing of best practices. With this theme in mind, Didier presented a short keynote on CSR in a business context by explaining how Close the Gap and WorldLoop aim to work towards a fully autonomous circular IT initiative aimed at re-using IT assets and recovering valuable materials (urban mining). The debate was, in other words, all about the optimization of global metal flows and stimulating closed loops in a qualitative way and enabling a circular economy.

During the panel, Didier's fellow speakers talked about policy issues on global trade of metals, the role of data in understanding metal flows, and the global recycling industry. Afterwards, a more general discussion between the panel members and the audience began. They addressed the contribution to CO² reduction and perspectives for 2032. Via an interactive feature, the audience could participate in the discussion, ask questions, and raise issues related to the discussed topics.
