On 22 and 29 June 2017 the offices of the OVAM in Mechelen (also known as Malines, in French) were the venue for the stakeholders from several industrial sectors, waste traders and research institutions. They met to discuss the pros and cons of an online symbiosis platform. Apart from getting insight in the expectations and relevant features of a future ICT-platform, a few more fundamental questions were raised: How does an ICT-platform safeguard a higher valorisation of waste? How do we guarantee the financial viability of the platform? How will we evaluate its success? How can we open up the debate on industrial symbiosis and circular economy from a mere academic debate to a common practice?
