The strategy aims to significantly reduce the use of new raw materials, thus contributing to a sustainable city. In the coming years, the City will map out various material flows, from entry to processing, in order to preserve valuable raw materials. The aim is to halve the use of new raw materials by 2030 and to achieve a fully circular city by 2050.In a circular economy we reuse raw and other materials over and over again. That way we avoid waste and close the cycles. We learn to do more with less. In a circular economy, the value of raw materials is retained as much as possible throughout a product’s lifecycle, from design to disposal. A ladder of circularity has been designed for this purpose, showing which processing options are preferable to others. As the City of Amsterdam, we are focusing on 3 value chains: Food and organic waste streams. Consumer goods. Built environment.
