Otpadna livačka šljaka, koja nastaje u procesu topljenja gvožđa i sakuplja se sa usta elektrolučnih peći,
u svim livnicama u Srbiji skladišti se na privremenim deponijama, obično u krugu fabrike. S obzirom na
velike količine otpadne šljake uočava se potreba trajnog rešavanja navedenog problema. Kao jedno od
rešenja nameće se mogućnost odlaganja livačke šljake kao tampon podloge ispod betonskog pokrivača.
Radi odlaganja ove vrste otpada izvršena su odgovarajuća geomehanička ispitivanja predmetnog
otpada. Zaključeno je da otpadna livačka šljaka, bez primesa komadnih materijala, mlevena na
granulaciju ispod 10 mm, skladištena tako da ne dođe do kontaminacije ugljovodionicima se može
upotrebiti za izradu posteljice puta i izradu donjeg nosećeg tamponskog sloja u granulaciji ispod 31.5
mm. Na ovaj način unaprediće se sistem upravljanja i tretman otpadom kao materijalnim resursom
zasnovan na naučnim saznanjima i postupcima a u skladu sa principima cirkularne ekonomije.
Waste foundry slag, which is formed in the process of melting iron and is collected from the mouths of
electric arc furnaces, is stored in all foundries in Serbia in temporary landfills, usually within the factory.
Given the large amounts of waste slag, there is a need for a permanent solution to this problem.
As one of the solutions, the possibility of depositing foundry slag as a buffer base under the concrete
cover is imposed. In order to dispose of this type of waste, appropriate geomechanical tests of the waste
in question were performed. It was concluded that waste casting slag, without impurities of piece
materials, ground to a granulation below 10 mm, stored so as not to contaminate with hydrocarbons
can be used to make the road bed and make the lower bearing buffer layer in the granulation below 31.5
mm. In this way, the system of waste management and treatment as a material resource based on
scientific knowledge and procedures and in accordance with the principles of... circular economy will be
improved.
