dc.description.abstractThe construction sector has a large environmental impact and waste contribution. The sector is the number one consumer of raw materials and 30% of global greenhouse gases can be attributed to the building sector. In the Netherlands the construction sector is accountable for 46% of total waste. This heavy environmental pressure stresses the need for reduction. The Dutch government has the ambition of having a circular economy (CE) by 2050 and a reduction of 50% in primary resource use by 2030 to decrease this environmental pressure. Fuelled by these ambitions, the development of tools that increase building circularity has been growing. So has the concept of a materials passport (MP). The materials passport can be considered as an inventory of building products used during construction and its characteristics. Rigid guidelines to what it should include are lacking and standardization is not present. Using qualitative interview data from experts and assessment of current existing MP practices, this research aims to identify the information needs, potential pitfalls to using the MP and assess its possible contribution in the transition towards a CE in 2050. Having information on what building materials, products and elements have been used in a building, is assumed to lead to more reuse at end of life (EOL). This research shows that for the implementation of the MP as a tool to accelerate the transition towards a circular construction sector, several important adjustments are necessary. The current existing MP practices do not resemble what the building sector thinks is necessary in a passport for it to be useful. According to the experts questioned in this research, information on releasability, material properties, dimensions, toxicity information and structuring based on lifetime is indispensable. Besides these information needs, the environment and infrastructure in which the passports operate can be considered as underdeveloped. Practices show that to achieve reuse, recovery or recycling, the passport is not necessarily the key to success. To use the passport as a tool that aids the transition from a linear construction sector to a circular sector, standardization according to previous needs is not the only necessity. Policymakers and the sector have to further develop the framework of the passport, the infrastructure it is embedded in and the supply chain cooperation that is required, whilst practices that achieve high reuse at EOL have to be supported to achieve short term impact.
