Summary: Rapid development of urbanization and the growing environmental concern have led to problem in waste disposal. Consequently, the following priorities have been established worldwide: measures for preventing the creation of waste, recycling waste material, burning waste and efficient waste disposal. The objevtive of all these activities is to minimize the size of sanitary landfalls. The research project is based on the above principles which will govern all the measures and activities related to the collection and neutralization of waste and the primary selection of substances which can be reused form the production of secondary resources. Accordingly, proposals and parameters for optimal use of the given method will be developed and an integrated approach to these problems will be adopted. Splecial attention will be paid to the citizen-city realtionship.

Keywords: Wastes reduce, Recycling, Land Filling

Research goals: All modern systems for waste management imply various organizational measures and legislation for avoiding waste formation. Subsequently, the measures for the re-use of wastes have been developed (primary recycling) as well as the measures for the disposal of hazardous wastes which are neutralized applying specific methods. Special attention is focused on the protection of the sea polluted by oils released from the ships. The main problem in waste management is to neutralize the remaining waste which amounts to 80% of the total waste quantity. The common method of neutralization is disposal. Since disposal implies vast areas of the terrain and long- lasting environmental protection (air, water etc.) additional methods should be used which reduce the quantity of waste after its recycling to the smallest possible quantity. One radical possibility is thermal treatment (burning wastes) which is, however, the most expensive method and is not suitable to be applied in this country. Alternative methods are composting (cold biological treatment) so that the wastes are degraded as soon as possible. Another method is pyrolisis, using gas as a fuel and production of fuel from the waste remains (RDF) to be used in the cement factories. Intensive "competition" between these methods is currently going on in order to find an optimal one to be widely applied. Thus, it is important to monitor the development and effects of these technologies considering the technical, environmental and economic aspects, i.e. the possibilities of our industry and financial means. The chief researcher had the opportunity of being the main coordinator in planning the system of wastes management in the Split region with the participation of 46 experts and researchers from 25 institutions. This project was co- financed by the World Bank and was accepted by the reviewers including the reviewer on behalf of the World Bank and the USA. According to the results of investigations it was suggested that the reduced quantities of the wastes should be used for fuel production (RDF) for the cement factories which are important in this region. The chief researcher has also had the opportunity as the reviewer of the Study of waste management in Zagreb to exchange his experience and results of the work on this Project and apply them to the situation in Zagreb. Accordingly, he developed a programme for the selection of a technology to be applied to the neutralization of the wastes. This programme implies a study of the experience in other European countries considering the latest methods of waste neutralization before reaching final decisions. Arrangements are currently being made for the participation of the chief researcher of this Project in the Study of waste management in the Rijeka region in order to apply the results of this Project in solving the problems in that region. The continuation of scientific research about the possibilities and methods of waste reduction and disposal of wastes is important for the problems in Split, Zagreb and Rijeka as well as for other cities in Croatia. Since different areas imply different solutions it is necessary to develop a Croatian Know-How with minimum investment, which should, however, make it possible to achieve efficient solutions.
