1Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium Promoting sustainability in aggregate supply – a Finnish case study Mika Räisänen and Hannu Idman Geological Survey of Finland
2Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium OUTLINE Introduction: Sustainable development in the context of mineral supply Present situation of aggregate production in Finland Promoting sustainability in aggregate supply of the Finnish society Future challenges
3Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium Non-extinguishable resourcesExtinguishable resources Flow resources: solar, wind, wave, rainwater Reservoirs: air (oxygen, CO2), oceans (water), geothermal energy Biological resources: forests, fish, biomass Reservoirs: fresh water basins, aquifers, fertile soil Recyclable resources: metals Recoverable Resources: other minerals, land Non-renewable and non- recoverable resources: fossil fuels: oil, gas, coal Non-renewable resources Renewable resources aggregates NON-RENEWABLE AGGREGATES Data from EuroGeoSurveys
4Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium Economic Growth Growth of resource use Growth of env’l impacts Relative decoupling Absolute decoupling Thematic strategy for sustainable management of Natural Resources Basic challenge in combining: - growing economy - developing society - sound environment Basic question: how can we as geoscientists promote decoupling? PROMOTING SUSTAINABILITY IN MINERAL SUPPLY
5Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium Basic features of the geology of Finland Neogene (Quaternary) Loose Sediments Derived from Last Glaciation Moraine, Clay, Sand & Gravel,Peat Precambrian Crystalline Basement From Archean to Proterozoic in Age Granitoids, Schists, Gneisses and Migmatites PRESENT SITUATION OF AGGREGATE PRODUCTION IN FINLAND
6Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium Production ca. 100 million tonnes/year 18 tonnes/capita Based almost entirely on: - sand and gravel deposits - crushed rock Use of aggregates concentrated in urban (growth) areas 2/3 is used for public applications Road construction (50%), building of houses (15 %), asphalt pavements 10 (%), concrete (10 %), and other (15 %) UTILISATION OF AGGREGATES
7Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium Natural resources: cover >> 95% of aggregate production Left-over resources: inefficiently used potential
8Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium Resulting in... - shortage of accessible natural materials at urban growth areas - continuous increase in transportation distances - increase of harmful effects from transportation (costs, emissions, noise, dust, traffic) - negative effects on construction industry, infrastructure, to functioning of society…..
9Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium PROMOTING SUSTAINABILITY IN AGGREGATE SUPPLY HOW? 1) By developing an accounting system that incorporates - data on natural aggregate resources - data on usage restrictions (e.g. natural protection areas) - data on left-over materials and industrial by-products - monitoring of extraction and utilisation 2) Optimising the usage of left-over materials and super quarries - the concept of centralised production areas (super quarries) and aggregate terminals - quality control of aggregate production as a basis for CE-labelled left-over aggregates - reclamation of quarries and end-use application of quarries (recreational, land fill areas, industrial and housing areas etc.)
10Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium WHO DOES IT? Environmental authorities and land use planners - environmental and land use data Aggregate companies - yearly information of extracted materials Geological Survey of Finland - data on resources - data management and interpretation - accountancy services for users good collaboration of stakeholders is needed legislative modifications also needed
11Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium WHAT THE SYSTEM PRODUCES? On-line information of aggregate resources and substitute materials (quality, amount, location, usability) On-line information on construction material flows A tool for decision-making HOW CAN IT BE USED? Via Internet WHO ARE THE USERS? Environmental and quarry permit authorities Land-use planners Aggregate producers WHEN IT WILL BE READY? For the natural aggregates in 2008 The substitute mineral materials to be integrated in following 2-3 years
12Sustainable resource management, raw material security December 6-7, 2006 in Bruges, Belgium FUTURE CHALLENGES The system provides an accounting system for natural aggregate resources and their substitutes and the system should be developed towards a comprehensive environmental accounting system that incorporates: - aggregate resources (natural, substitutes) - utilisation and future consumption predictions HOWEVER Methodological development is needed for: - valuation of aggregate stocks - environmental impacts also in monetary terms - cost analysis of the other environmental values (e.g. scenic values, dust, and noise, eco-efficiency of by-products).
