Challenge to be solved: How can we reduce resource consumption in construction?

When buildings are demolished, most materials are not reused and end up in landfills. There is enough data regarding efficiency, source etc. for new materials, but this is often not the case for materials that are part of already existing buildings. When a new building is constructed, it consumes a lost of resources and raw materials. Why not connect these two issues?

The presented solution is the creation of a cradle-to-cradle municipal material bank. The main idea resides in an e-material bank, a platform that aims at categorizing the different materials that result from the demolition of a building. It will use existing data streams from the municipality and expand them, acting as a data source for customers.

Features of the platform:

-Categorization of materials and material pooling: life cycle, technical features, alternative uses

-Provider of simulation/modeling for companies to know exactly what materials are needed and amount needed to construct the desired building. This will also reduce the consumption of unnecessary resources

-There is a need for technology in order to optimize materials for their new uses and identification of the materials' potential

Together with an e-material bank/e-platform, there is a need for a physical material bank where the materials are stored (this point could relate to some of the other challenges exposed, like utilization of empty buildings in the municipality)

Inputs and outputs from the different stakeholders: 

-Company in charge of a demolition gives the resulting construction materials to the municipality, in exchange they will get a small incentive, which adds a revenue for the company

-Municipality receives materials, does material pooling and creates value by categorizing them and providing detailed information about their life cycle, quality control and also tracking and traceability apparatuses. The municipality's revenue originates in the sale of recovered materials to construction companies for a cheaper price. They are also providing added value to the material.

Most likely, technological barriers for the material categorization must be overcome.

Existing data on materials from the municipality can be used but the platform's aim is to create new data by categorizing each material.

The circularity of the solution can be seen in the attached picture. Materials processed (=categorized and distributed) by the material bank are then used for new buildings. Knowledge is being generated throughout the cycle.

There is also creation of value for demolition companies, that add a revenue to the materials, since they are not considered waste. For the municipality, it creates employment. By connecting different actors and incentivizing circularity, it removes waste and resource extraction, which means ultimately value for citizens.
