Important results from the project
The project has shown that several residual materials can be used directly in municipal construction projects, included as sub base layer in paved surfaces. Through pilot installations, function and feasibility were verified. Project objectives were fulfilled via training and fact sheets that e.g. strengthen environmental officers’ knowledge. Several municipalities are more positive toward the recommended use now! For more information, see: www.ri.se/sv/circulara-anlaggningsmaterial.
Expected long term effects
The project is expected over time to strengthen confidence in circular materials as equivalent alternatives to crushed rock in construction works. Several materials harden over time and improve performance and service life, reducing maintenance needs. Increased use of local residual materials reduces transport and thus lowers climate impact. Some materials also bind carbon dioxide. Overall, the project supports a long-term transition toward circular resource use in urban development broadly.
Approach and implementation
The project has worked on a broad scale, involving all partners in all activities to increase understanding of synergies and effects. The collaboration has worked very well and resulted in strengthened ties between partners. One objective was to secure several test areas with many partners to spread expertise and understanding and create commitment. In addition, this contributes to a more secure project outcome as municipal plans rarely synchronize well with the schedule for research projects.
