Waste Management System with Regard to the Bjelovar-Bilogora County

Otpad je jedan od ključnih problema moderne civilizacije i rezultat našeg načina života. Stvaranjem sve većih količina otpada čovjek znatno narušava prirodnu ravnotežu, stoga je pitanje saniranja odlagališta otpada i uopće njegova adekvatnog zbrinjavanja u samom vrhu prioriteta, jer se na takav način smanjuje zagađenje okoliša. Neodgovarajuće gospodarenje otpadom uzrok je sve zagađenijeg okoliša u Republici Hrvatskoj. Količina otpada stalno raste, a infrastruktura, koja bi taj otpad trebala zbrinuti, nije dostatna. Sustav gospodarenja otpadom ne funkcionira u potpunosti, a propisi koji utvrđuju gospodarenje otpadom ne provode se u cijelosti. Hoće li izmjene Zakona o otpadu dovesti do poboljšanja općeg stanja ili će se problem još više produbiti te kako se s tim nose manje sredine? - najčešća su pitanja struke i znanosti. U radu je prikazan plan sustava gospodarenja otpadom u Bjelovarsko-bilogorskoj županiji te analiza zacrtanih ciljeva.Waste represents one of the key problems of the modern civilization; it is a result of the today way of life. By collecting bigger and bigger quantities of waste, people disturb the natural balance to a high extent; hence, one of the priorities in reducing the pollution of the environment is choosing the right approach to solving the waste problem. Inadequate waste management is the most serious ecological problem in the Republic of Croatia. The quantities of waste constantly grow, and the infrastructure responsible for waste disposal is insufficient. Neither does the waste management system function in full nor is the waste management legislation properly implemented. Both profession and science often wonder whether the amendments to the Waste Act will result in a better general state or will the problem become even more serious, as well as how smaller communities deal with this issue. The paper will present the planned waste management system in the Bjelovar-Bilogora County and an analysis of the set goals

Ružička days : International conference 19th Ružička Days “Today Science – Tomorrow Industry” : Proceedings

Dear colleagues, we are extremely honoured to present to you the Proceedings of the international conference 19th Ružička Days, which was successfully held on September 21–23, 2022, in Vukovar, Croatia, in the hometown town of our famous Croatian scientist and first Nobel laureate, professor Leopold (Lavoslav) Ružička. The main goals of the Conference were to promote excellence, originality and innovation of interdisciplinary scientific research as well as the practical application of the obtained results through collaboration with industry, emphasizing thus the recognizable slogan of the Ružička Days conference: "Today Science – Tomorrow Industry". In addition, the Conference gave the opportunity for meetings, exchanging the ideas, opinions, experiences and cooperation among participants from different working surroundings. It is also important to point out that since 2008, within the international conference Ružička Days, Meeting of Young Chemists has also been held, where high school students, with the help of their mentors, present papers in the field of chemistry, with the aim to direct students and young people to the technical and natural sciences, especially chemistry. In its seventh issue (2011, 2013, 2015, 2017, 2019, 2021) the Proceedings publishes scientific and professional full papers of high quality in the following sections: Chemical analysis and synthesis (10), Chemical and biochemical engineering (3), Food technology and biotechnology (4), Chemistry in agriculture and forestry (1), Environmental protection (9) and 8th Meeting of Young Chemists (3). Full-length papers were subjected to an international review procedure done by eminent experts from the corresponding fields, to whom we express our gratitude, but they were not subjected to linguistic proofreading. On behalf of the Scientific and Organizing Committee of the 19th Ružička Days we cordially thank all the authors, reviewers, participants, lecturers, organizers, especially the international organizers EuCheMS and EHEDG, auspices and sponsors, and all the others who, in any way, supported the Conference and contributed to the preparation of the Proceedings, especially to our highly skilled and committed associates, who have put a lot of effort in the preparation of these Proceedings. At the very end, special thanks to our young, future scientists and their mentors who are faithful participants of the Meeting of Young Chemists of the Ružička Days conference. Enjoy the extremely interesting scientific and professional papers contained in these Proceedings, until the next 20th jubilee of Ružička Days in 2024! We are looking forward to meeting you again in Vukovar! Yours sincerely, Chief Editors Jurislav Babić Vesna Ocelić Bulatović Dajana Kučić Grgi
