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.
