Maeconomy raises €1.5M to give building materials a digital identity

The Dutch startup is tackling one of construction’s most stubborn problems: the fact that most building materials lack traceability, making them impossible to reuse when a structure is demolished or renovated.

Maeconomy, a Dutch startup, has raised €1.5 million to build a platform that turns building materials into auditable, monetisable circular assets. The Netherlands has been one of Europe’s leading markets for circular construction thinking, and the problem Maeconomy appears to be addressing is a structural one.

Construction and demolition waste is the largest single waste stream in the EU by weight, yet the vast majority of materials removed from buildings are downcycled into low-value rubble rather than recovered for reuse, because no reliable record exists of what those materials are, where they came from, or what condition they are in.

The solution Maeconomy is building is a variant of what the construction industry calls a material passport, a digital identity record for each material component in a building.

The concept has been around for years: Dutch companies including Madaster have built registry platforms for material passports, and the approach has been piloted on office buildings in Amsterdam and commercial schemes in London.

What distinguishes Maeconomy is that its platform is designed not just to record materials but to make them “auditable” and “monetisable”, embedding the financial dimension of residual material value directly into the asset record, so that building owners can treat their structures as material banks with quantifiable and tradeable future value.

The Dutch construction sector accounts for 50% of all raw material consumption in the Netherlands, and the government has a 2030 target to halve the use of new raw materials.

European regulatory pressure is intensifying: new buildings in several EU markets are increasingly subject to requirements around circular design, and material passports are moving from voluntary best practice toward mandated documentation in some jurisdictions.

A platform that makes the financial value of building materials legible, and auditable for investors, insurers, or resale counterparties, addresses a real gap between the ambition of circular construction policy and the commercial infrastructure needed to make it work at scale.
