Summary: The current utilization of leftover aggregates formed by earthworks and bedrock quarrying in Finland. Geological Survey of Finland, Report of Investigation 177, 39 pages, 14 figures and 6 tables. The availability of rock aggregates is becoming more difficult in Finnish urban regions and transportation distances are increasing. On the other hand, a large amount of leftover aggregates accumulates by earthworks in construction areas and through quarrying. These are not always effectively utilized but are dumped at landfill sites. This study is part of a project entitled Construction and Aggregates (RAKI) carried out by the Geological Survey of Finland (GTK). The aim of the project is to promote the utilization of leftover aggregates in order to spare natural resources. The current situation and obstacles to the utilization of leftover aggregates were investigated with an enquiry addressed to municipalities, environmental authorities, provincial federations and aggregate companies. A detailed description of the conditions in the Helsinki and Tampere regions has been included. Authorities in municipalities estimated that 10 to 100% of accumulating leftover rock aggregates is utilized. Estimates of the utilization of leftover soil varied even more. Half of the authorities in municipalities and less than half of the environmental authorities and aggregate companies reported that statistics on the accumulation and usage of leftover aggregates are compiled in the districts they represent. Refinement and storage areas for leftover aggregates have been appointed by plan drawing in every third municipality. An aggregate accounting system only exists in the region of two responding municipalities and four aggregate companies. However, stone and mineral wastes from quarries and mines will in the future be tracked in GTK’s web service, the Geological Resource Inventory. Leftover aggregates in Finland are currently only supplied on the market via a few domestic websites. According to the enquiry, the biggest obstacles hindering the efficient utilization of leftover aggregates are the lack of operational areas, poor profitability, attitudes, defects in legislation and variation in the availability and quality of leftover aggregates. Operational areas should be appointed in provincial and/or municipal planning. Legislation in the field could be clarified and, to a certain extent, lightened. Information on the application of leftover aggregates and other materials substituting natural resources should be increased. An aggregate accounting system with real-time information on the availability of leftover aggregates should be widely introduced.
