The Netherlands is on the brink of transitioning to a circular economy. The ambition expressed in the Dutch national scheme 'Nederland Circulair in 2050' clearly indicates the direction: 50% reduction in primary raw material consumption by 2030, and a fully circular economy by 2050. This transition also applies to the construction sector. The objectives for this are set out in the Transitieagenda Circulaire Bouweconomie and the associated Uitvoeringsprogramma. One thing is clear: 'circular' is currently one of the main themes in society, both in the construction sector and elsewhere.
