  1. Faculty of Mechanical Engineering University of Nis, Serbia Ph.D. Gordana Stefanović, Assist. Prof. Dušan Marković, Ph.D. Student COMPARATIVE ANALYSIS OF THE WASTE MANAGEMENT POSSIBILITY ON THE TERRITORIES OF SERBIA AND CROATIA XIth International Symposium Waste management Zagreb 2010, 25-26 XI 2010. Zagreb

  2. Content • Introduction • LCA of product and LCA of the waste • IWM model • Indicated parameter of the model • Model limitations • Waste quantity and quality analysis (Nis and Zagreb) • Scenarios 1-4 • Results and discussion • Conclusions

  3. Introduction • SWM trends • State of the art in Europe • State of the art in Serbia and Croatia • Future plans • LCA

  4. State of the art in Europe

  5. State of the art in Serbia and Croatia

  6. LCA • The European Commission Communication suggests inclusion of waste treatment environmental impact in the European Union waste hierarchy • Life cycle assessment (LCA) is used for measuring environmental impacts and identifying priorities. • Why is this way of observing good? • It considers other aspect, not only the economic!

  7. Aim of the study • The aim of this study is the application of the LCA procedure to MSW management in two cities (Nis and Zagreb) in order to choose the best management system from the aspect of environment protection.

  8. Processes included in the model: Waste colection Transport Sorting and prepearing of recyclable materials Recycling Composting Anaerobic digestion Waste incineration Waste Depositing The specific evaluated indicator parameters: Total consumed/saved energy, Greenhouse gases, Acid gases, Smog precursors, Heavy metals emission, Trace organics, Biochemical oxygen demand, Residual solid waste. IWM Model Model limitations: • Infrastructure is not considered • LC of the landfills is estimated at 100 years • All treatment ways did not consider • Waste reducing on the place and reusing did not consider • All waste streams did not considered (dangerous waste,..)

  9. SW quantity and quality

  10. SCENARIO 1 - bazni scenario Municipal Solid Waste 20% recyclable packaging waste Rest of waste Plant for sorting and preparing recyclable material recycling Landfill Landfill gas Recycled material Landfill gas

  11. SCENARIO 2 Municipal Solid Waste Organic waste Rest of waste Plant for sorting and preparing recyclable material Komposting Plastic Metal Glass Paper kompost recycling recycling recycling recycling Landfill Recycled material Deponijski gas

  12. SCENARIO 3 Municipal Solid Waste Rest of waste Plant for sorting and preparing recyclable material Incinerator Cement industry Fly Ash Glass Metal Bottom ash recycling recycling Landfill Recycled material Landfill gas

  13. SCENARIO 4 Municipal Solid Waste Rest of waste Plant for sorting and preparing recyclable material Anaerobic digestion biogas Plastic Metal Glass kompost recycling recycling recycling Landfill Recycled material Landfill gas

  14. Results

  15. Results and discussion • The main findings of the study can be summarized as follows: : • Having in mind the plan of installing a waste recycling plant in Nis, scenario 2 would be most suitable to the set demands.As the minimal amount of waste for depositing is gained in scenario 4, this scenario is also of importance for Nis having in mind the capacity of the existing landfill. • Considering thermal treatment of MSW in Zagreb, the waste treated in scenario 3 will reduce the demand of energy from fossil fuel, but, if virgin material displacement credit is taken into account, i.e. complete net life cycle inventory, scenario 2 is the best, in terms of energy saved.

  16. Conclusions • LCA is a very powerful tool for assessing the potential environmental impacts of different waste management strategies • The results demonstrate that, if the system is modeled in sufficient detail, LCA can identify not only the best scenario, but also the analytical contribution of single operations to the overall environmental performance of the system. • Results obtained from this study also support the conclusion that LCA, as an environmental tool, can be successfully applied in an Integrated Solid Waste Management System (ISWMS) as a decision support tool.

  18. Kolicina otpada koja se generise na teritoriji Srbije I Hrvatske kao I njiegov sastav je prilicno slican. U odnosu na zemlje Evropske Unije kolicina otpada u obe drzave po glavi stanovnika se nalazi na donjoj granici. Od ukupne kolicine otpada najveci deo se deponuje, dok se svega oko 5% reciklira. Obe drzave su u potrazi za savremenim modelima upravljanja otpadom imajuci u vidu odrzivi razvoj i bast available technologies. • LCA is a very powerful tool for assessing the potential environmental impacts of different waste management strategies. • U radu su prikazana cetiri alternativna scenarija for the MSW management of the city of Zagrab and city of Nis. Prikazani rezultati demonstrate that, if the system is modelled in sufficient detail, LCA can identify not only the best scenario, but also the analytical contribution of single operations to the overall environmental performance of the system. • In accordance with the results obtained from this study, scenario 2 ima najmanji uticaj na zivotnu sredinu, dok je scenario 3 is the most environmentally sound option, in terms of water pollution. The minimum amount of final MSW disposed was obtained from scenario 4 • Considering thermal treatment of MSW in Zagreb, the waste treated in scenario 3 will reduce the demand of energy from fossil fuel, but, if we take into account virgin material displacement credit, i.e. complete net life cycle inventory, scenario 2 is the best, in terms of energy saved. • Imajuci u vidu plan da se u Nisu instalira postrojenje za reciklazu otpada, scenario 2 najvise odgovara postavljenim zahtevima. Takodje I scenario 4 u kome se generise najmanja kolicina otpada moze biti od znacaja za Nis imajuci u vidu kapacitet postojec deponije. • Results obtained from this study also support the conclusion that LCA, as an environmental tool, can be successfully applied in an Integrated Solid Waste Management System (ISWMS) as a decision support tool.
