Madaster Data Services For Real Estate


Madaster is the cadastre for materials. Raw materials are scarce but limited and must therefore be well documented so that they remain unlimited. With the help of the material passport, materials get an identity, which means that they can never disappear in anonymity as waste. Madaster acts as a library and generator for material passports. An independent platform accessible to all: individuals, businesses and governments. Madaster is being developed under the supervision of the Madaster Foundation.

Madester Services

Madaster Foundation has outsourced the development and management of the Madaster Platform to an implementing organisation: Madaster Services B.V.  As of 1 January 2017, the day-to-day management of Madaster is handled by two directors. The directors consult with the Madaster Foundation on the policies to be implemented and represent Madaster at home and abroad. The directors are appointed in consultation with the Madaster Foundation.

Madaster Origination : Material Matters

In 2016 Thomas Rau and Sabine Oberhuber published the book ‘Material Matters’. The book describes the tranisition to a new economic system where consumers are no longer owner, but temporary user of products and materials. Their view was captured in the VPRO ‘Tegenlicht’ broadcast (“Het Einde van Bezit”) on Dutch public television called. Madaster was based on these insights and concepts. The paragraphs below are extractions of the book ‘Material Matters’ and based on interviews with Thomas Rau. The sections illustrate the conceptual background of Madaster.

Responsibility For Materials

“First, we must realize that with ownership comes responsibility. Nowadays, by necessity, all kinds of items end up in our possession for which, in the long term, we cannot bear responsibility. If the building we work in no longer meets our requirements, we are completely out of our depth when are asked to consider its responsible use. We are not able to take care of all (raw) materials that were used to create the building – let alone reuse them. To make things worse: we often have not got a clue which (raw) materials were used, or what properties these materials have.”  (Source: paraphrasing Material Matters)

Registry Of Materials

“In the meantime, we find ourselves in an untenable situation. We mine raw materials, turn them into goods. Those goods are used, or used up, and then thrown away – end of story. The whole chain contributes to this system: from designers and builders, to manufacturers and investors. This means that the consequence of consumption within this system is practically always the same: waste. “ (Source: paraphrasing Material Matters)
“What is waste? Waste is material that has ended up in anonymity. A lot of waste is incinerated, which could be considered a cremation of raw materials. How can we prevent this? By providing everything with an identity, and well by documenting it, by giving it a passport. Hence the materials passport. Subsequently, we must facilitate access to these passports, as to a library. This is how we arrived at the idea of a real estate materials register: Madaster. A public platform for the entire real estate business. You could look at it as a civil register for materials.

Madester Data Services

We have a boundless ambition to make information ever more accurate, structured, and accessible. The Madaster platform offers a rich and growing quantity of valuable data that you, as a real estate service provider, can leverage.

The data of a specific real estate object remains the property of the owner of the building. The complete data set on the platform is supervised by the Madaster Foundation in order to guarantee the privacy, security, and public availability of the (anonymized) data. Through Madaster Data Services, this public data is offered to the market in anonymized form, unless the building owner has explicitly granted access to building-specific data.
Through our open technology, tools and techniques, service providers, governments, and scientific organisations are stimulated to join the Madaster Platform. The platform and its publicly accessible data drives development of new, innovative business models.
