1 CONTEMPORANY AND FUTURE TRENDS OF CRUSHED STONE INDUSTRY IN ROMANIA Dr. eng. Valentina Cetean

3 General considerations Despite the low value of its basic products, the CRUSHED STONE industry is a major contributor and an indicator of the economic well-being of the Nation Legislation and Government Programs The situation of aggregates and crushed stone production in 1989 have been: UM River aggregates Crushed stone x 1000 m % 94 6 The river aggregates represent about 34% of all extract raw materials, but in many cases, that induce and environmental problems To reduce the impact of anthropic activity on the river proximity, the present and future trends are to increase the volume of crushed stone that will use like a substitute for the river gravel and sand.

4 Examples of environmental problems at processing river aggregates station

5 THE EVOLUTION OF CRUSHED STONE INDUSTRY IN THE LAST DECADE The industry of aggregates exploitation and processing give all the raw materials to the civil and building activity. Before to 1989, all extractive industry belonged to national property, which 42% to the Ministry of the Wood Industry and Building Materials. In the period all the stone industry has been on the wane, result of general decrease of investments in the construction activity, return to the civil buildings with 1-4 floor, construction of industrial buildings with other type of materials, decreasing of road and railway construction / maintenance.

6 IN PRESENT At the same time with the political and economical changes in the old socialist European countries, new investments made in the mineral activity. I was created new jobs, more work places, technological transfer, infrastructure development and local services. A big crushed stone quarry of Lafarge at Malnas In present, the activity carry out by big private company (like HEIDELBERG CEMENT Group and LAFARGE Group) and a lot a small firms. This is a good opportunity for development, but for the statistical evaluations and the perspective programs is very difficult sometimes to show a real situation, because a lot of them refuse to give information concerning to production.

7 The aggregate domain has a competitional market, because the technological capacities are biggest then needs. The comparative numeric analyze between natural aggregates and crushed stone show more then 800 quarries, in exploitation, ceased or not open activity: Specification Type of rock Natural aggregates Crushed stone Guarantee period - Industr Unit of years - ial measure stopped volume in exploit. activity Sand and x 1000 m gravel Granodiorite x 1000 tone Granite x 1000 tone Diorite x 1000 tone Dacite x 1000 tone Basalt, x 1000 tone diabase Andesite x 1000 tone The placement of the exploitations and/or processing of stone units or concrete and prefabs factory is equilibrate in the national territory, with maximum 120 Km to the initial deposits.

8 The crushed stone deposits from Romania

9 In the construction aggregates domain, physical productivity of economical agents in the last period and for the next years are: A temporary activity at the Seini andesite quarry only for the roads construction The aggregates there are obtained in fit technological high tide respect the value of standard, like crushed stone from European Community. Beside, this remark is confirmed by the quality of concrete with Romanian aggregates.

10 LEGISLATIVE RULES Even the great concerns and a part of small firms allocated a lot of money to be conform with the international environmental rules, the current activity involve a change of natural environment. An important crushed stone (dacites) quarry at Tunel Magura Ilvei, close of a railways, where the exploitation induces the changes of natural equilibrium parameters

11 In the concordance with the actual rules, the modality to extract the raw materials is to have the official permit or license, emit by National Agency for Mineral Resource. These rules include : one technical part of activity sustain (resources evaluation, laboratory studies, feasibility exploitation study, plan for exploitation development, documentation for social impact, study of environmental impact assessment, plan for environmental reconstruction when the rule of geologist is very important; one legislative part (all agreements from legal institutions like Ministry of Watters and Environmental Protection, the owners of land, the near community, the local agencies for energy, for health, etc.) A small crushed stone (marble) quarry at Fantana Borsa, very close to the environmental reservation of Rodnei Massif

12 MANAGERIAL POLITICS To succeed in the proper activity and in the frame of European rules, more and more strictly, the most number of firms wish to obtain and to demonstrate a good stage of environmental performances, by control of processes, services or products. One of method is the implementation of Environmental System Management, conform to EN ISO 14001:1995. The aim is to supply of elements for a real and good environmental management, integrated in the general politic of organization. In present, the mean direction for such firms are: to certify the quality of products by Romanian and European rules; to achieve the products only by conformity with standards, norms, technique specifications; to organize a proper laboratories for analysis and quality control; to pursuit of the flux manufacture; to change the unperformed equipments; to elaborate and respect the environmental programs and introduce the Quality and Environmental System of Management

13 THE FUTURE In Romania, the raw materials for civil and industrial manufacture, roads, streets, embankments are ensured by internal resources from open quarries and is enough quantity for the next 50 years. Specification Natural aggregates Crushed stone In exploitation - permanent seasonal Ceased activity Not open TOTAL The guaranteed period with provided aggregates resources The aggregates production has a good distribution in territory, a long tradition and experience and qualified people.

14 THE FUTURE The future managerial trends the owner of quarries what produce crushed stone are: - the administration of technological wastes; the recycling and capitalization of wastes; - the adoption of solution to integrate in habitat of area which was affected by raw materials exploitation/ processing; - the implementation of environmental system management (with procedures and production criteria) and further environmental adopted programs; - the permanent assistance and communication between different levels of organizations. The quarry from Racos, where the scoria is used us light aggregates in the concrete industry

15 Link with a aggregates production, the specific program for the next 10 years foresee: Re-launching of activity in the building domain; The building of new houses; The growth of living conditions and life; Reorganization and development of transport and infrastructure of transport by road and by railway.

16 CONCLUSIONS The many of river flows will be rehabilitated. A part of river aggregates quarries will continue their activity. But many of these quarries will be closed.. The river aggregates quarry of CARPAT AGREGATE firm from Mihailesti lake The river aggregates quarry from Beclean, on Somes river

17 The aggregates quarries of CARPAT AGREGATE one of biggest group on Romanian market In present, most part of firms recognized the importance of conformity with proper activity, the real or potential impact concerning to environment, the necessity to training of the employments and the knowledge of consequences of extraction procedures, the adoption of measures for decreasing the pollution.

18 CONCLUSIONS The analyze of governmental program for the next decade - in the same time with the statistical data show a good repartition in territory of quarries for crushed stone and river aggregates what will be use for civil and industrial buildings, construction / modernization / maintenance of roads, streets and railways. The future of aggregates demand on the Romanin market have to be cover more and more by sustainable using of crushed stone. In the same time, have to follow the new rules for monitoring, protection and reconstruction of affected areas by exploitation.

19 We need the aggregates for our buildings

20 and for our roads
