Managament of recycables from municipal solid waste

This paper consists of two separate parts, the first one consisting of one and the second one consisting of two parts. The first part presents an analysis of communal waste amount in Banja Luka region, in the Republic of Srpska. Amounts of the waste from the regional landfill, into which the communal waste from eight municipalities in the region is being transported, are shown. Changes of waste amount have been analyzed in the function of changes in population, national income and season. Based on the data and functional dependencies presented in this paper, it is possible to estimate the amount of waste in future years, through further analysis. Formed model could be also applied in the regions with similar level of development, geographic and demographic characteristics. In the second – experimental part of the paper, measuring of mechanical characteristics of multiple processed waste polypropylene filled with glass powder with granulation less than 0,5 mm was performed. Changes of mechanical characteristics of pure polypropylene and polypropylene with addition of 5%, 10%, 15%, 20%, 25% and 30% of mass share of glass powder through six cycles of treatment were monitored. Research was carried out through tightening, bending, removing, pressing, crawling, stroking and hardness testing. Based on the measured values of characteristic parameters, values of voltage and deformities were obtained. In the third part, the results obtained through experimental method were analyzed, and using the method of the least squares, change dependencies of the observed parameter were formed (voltage, elongation, deformity and hardness) in the function of processing cycles and share of glass powder. Rad je koncipiran tako da se sastoji iz dvije zasebne cjeline, od kojih se prva sastoji iz jednog, a druga iz dva dijela. U prvom dijelu rada prikazana je analiza količina komunalnog otpada u regionu Banja Luka – Republika Srpska. Iskazane su količine otpada sa regionalne deponije u koju se sliva komunalni otpad iz osam opština regiona. Izvršene su analize promjena količina otpada u funkciji promjene broja stanovnika, nacionalnog dohotka i godišnjeg doba. Na osnovu podataka i funkcionalnih zavisnosti predstavljenih u radu može se u daljim analizama izvršiti procjena količina otpada u narednim godinama. Formiran model bi se mogao primijeniti i na regione sličnog stepena razvoja, geografskih i demografskih karakteristika. U drugom - eksperimentalnom dijelu rada vršeno je mjerenje me
