This diploma thesis is the result of research on the multifaceted issue of marine pollution from maritime industry. The thesis focuses on and aims at offering possible solutions to reduce the accumulation of waste in the sea and along the coastline that is a result of negligent and irresponsible management of the marine environment and therefore adversely affects human health, and the marine flora and fauna. The final result of the thesis comprises the outline of a treatment plant, the operation of which will contribute to a port whose maintenance, design and development are sustainable. The treatment plant’s purpose is to contribute to nature protection and the conservation of invaluable flora and fauna. Its function is to collect solid waste, waste oil, microplastics and similar smaller waste particles and substances by using an alternative source of energy.
The first part of the research-analysis section of the thesis includes a description of marine tourism and lists factors, services and infrastructures present in marine tourism destinations, while the second part outlines the ecological aspect of marine tourism and discusses its dependency upon natural factors that are increasingly under threat. The state of play concerning the sustainable approach to and the sustainable development of marine tourism is also presented. The third part provides an overview of challenges present in the Adriatic and on the Croatian coast. The focus than narrows to the area of Istria and finally to the port of Novigrad, which was used as the potential future working site for the implementation of the planned concept of the treatment plant.
In the synopsis of the thesis, the issues, goals and premises regarding the conceptual solution are defined. The final part provides a solution to the on-going issue, illustrated with drawings, visualizations and technical plans.
