2018 symposium by the KIT Faculty of Architecture

Sabine Oberhuber is a business economist, together with the renowned architect Thomas Rau, she founded Turntoo in 2010, one of the first companies worldwide to focus on the implementation of the circular economy. She supports companies and public institutions in the development and implementation of circular business models and is a guest lecturer at various universities. Together with Thomas Rau she wrote the book “Material Matters”, which offers a holistic model for a Circular Economy. 

Sabine Oberhuber is also co-founder of Madaster, a resource cadastre for the construction industry, which she presented in more detail in her lecture at the symposium, held by the KIT Faculty of Architecture in November 2018:
It is Madaster’s mission to make material available forever by giving it an identity. When materials have an identity, they can never disappear in anonymity as waste. Every building becomes a depot of materials with a certain value. To achieve this, the Madaster platform creates transparency about material assets in the built environment. Product and material data can be stored, enriched, shared and managed. A material passport gives insight into the materials, components and products used to create a building, and into their quantities. Additionally, the material passport contains information on the quality of materials, their locations, and their monetary and circular value. This way, it becomes a lot easier to reuse materials, minimize waste, and to reduce the cost of material consumption. Improved insight into the use of materials will stimulate the circular economy and will lead to better design solutions.

Together with an ecosystem of partners, Madaster provides smart data management tools and insights that enable sustainable decisions and value creation – for business success and a healthier planet. With a strong focus on privacy, security and continuity, the platform will be globally available and compatible with regional practices and standards.
