Circular economy by upgraded aggregates and demolition material

Reference number
Coordinator Swerock AB
Funding from Vinnova SEK 7 876 364
Project duration May 2019 - May 2021
Status Completed
Venture Challenge-driven innovation - Phase 2 Collaboration

Purpose and goal

The project objective was to produce quality-assured ballast from excavated and demolition masses that compete on equal terms with natural materials. Development of wet sieving methodology resulted in several quality-assured, CE-marked materials that were tested in construction projects. Short transport chains reduce climate impact and pressure on rock and gravel pits. Increased knowledge of social norms in the value chain increases the possibility of mutual understanding and acceptance of the produced material.

Expected results and effects

Through technical innovations, production capacity was increased 3 folds towards compared to objectives. Content of unwanted matter was reduced, and products could be quality assured and CE marked. Great interest in information initiatives, and the fact that several actors are planning their own facilities, shows the industry´s acceptance. Certified products are necessary for being accepted by authorities and requested in procurement. Increased knowledge of the market, standards and business systems means that the business can be further developed.

Planned approach and implementation

The project management was integrated into regular production, which resulted in short information chains. Established contacts with users simplified information gathering and testing. Innovation models and systems knowledge put the project in a wider context; degree projects strengthened the increase in knowledge. Gender equality and economics research raised the level in these areas considerably. Communication across the country was hampered by the pandemic, but could be offset by digital solutions, which also increased the number of participants at the Nordic webinar.
