Lieze works as the head of the international policy unit at OVAM, the Public Waste Agency of Flanders, which ensures that Flanders deals with waste, materials and soil in a well thought out and environmentally sound manner. Since 1981, OVAM has been developing a balanced mix of economic and regulatory instruments on waste, materials and soil that has made the Region of Flanders one of the frontrunners in Europe in this field.

We are joining forces with our partners in business, civil society, research and government to develop a circular economy, taking a multi-stakeholder participatory approach. Circular Flanders, which was initiated by OVAM, serves as hub, inspiration and matchmaker for the transition to a circular economy in Flanders. We implement measures that go beyond sorting and recycling waste to make a systemic shift from take-make-waste to a new economic model that factors in the scarcity of raw materials and the ecological limits of our planet.
