Attractive cities with reduced congestion through circular solutions for management of excavated soils and rock

Purpose and goal

The purpose of the project was to analyze possible ways to minimize transport of fill materials and increase resource efficiency. The project has studied and identified great potential of three identified solutions, decreasing the number of vehicle movements for fill material transport and resulting climate gas emissions: i) systems for better coordination of fill regionally, ii) more efficient transports using heavier vehicles and/or sea freight, iii) techniques for noise reduced crushing of rocks.

Expected results and effects

The systems and techniques investigated contribute to a potential 30-50 % decrease in transportation and at least 30 % decrease in climate gas emissions. Coordination of fill materials contributes most to the decrease in climate gas emissions and resource efficiency. Decrease in transportation is best gained from using heavier vehicles. Sea freight has good potential at decreasing transportation need over long distances. There is a sincere interest in the building industry for noise reduced crushing and means for further tests has been granted by development fund SBUF.

Planned approach and implementation

The project has been conducted through interviews, meetings and workshops with municipalities, building contractors and transporters to develop the solutions reviewed. Transportation need and climate gas emissions was calculated. The issues in focus have been established in the political management of the municipalities involved resulting in unusually many different municipal functions being able to partake in the work. The engagement of central authorities, and one international actor, enables spreading to a wide circle
