Tiivistelmä
Geological Survey of Finland has offered a free access to the data gathered during the “Kaikki käyttöön” Project, which has become the base for the study on the logistics of mines and quarries operating in North Savo region, Finland. The Final Thesis is based on both the data gathered by the “Kaikki käyttöön” Project and research literature. Currently quarrying operations in North Savo region result in production of a large quantity of leftover stone mate-rial, which is staying unused and piled on the site.
Leftover stone material generated during mining varies greatly, from dust and sand-sized particles to large boulders. It can be a substitute for primary aggregates, which are used in construction process in very large quantities. Aggregates produced from leftover stone mate-rial are highly suitable for road construction and concrete production.
The aim of the “Kaikki käyttöön” Project is to study the possibility of recycling and re-using leftover stone material from mines and quarries, benefits and disadvantages of it, whether it could be implemented cost-efficiently in North Savo region of Finland, with the prospect of applying in other regions. Recycling and re-use of leftover stones has been rather limited mainly because of a high rate of transportation costs. One of the main goals of the project is to clarify and estimate transportation costs that occur, when transportation of leftover stone is performed by different transport modes. Transport modes observed in this research report are road, rail and water transport.
In the future, gravel and sand will be more difficult to obtain, and the production of crushed rock aggregates will accordingly increase. The price of aggregate material at the site where needed will increase depending on availability, longer transport distances and requirements for higher quality materials (Finland’s Mineral Strategy 2010, 15).
At present, transporting of crushed stone by road is expensive over long distances, more than several tens of kilometres. Intermodal transportation is effective in a “port-to-port” system. Accordingly, if mines and quarries are remote from existing infrastructure, it creates a need for new logistic and financial solutions.
