Analysis of liquid eluate of fine waste fraction

Otpad je tvar ili predmet koja se odbacuje, namjerava ili mora odbaciti. Često se smatra pokazateljem gospodarske snage te razvijenosti društva. Neizbježno nastaje kao posljedica svakodnevnih ljudskih aktivnosti te je jedan od ključnih ekoloških problema današnjice. Djelovanje otpada može uzrokovati emisije u tlo, vodu i zrak, a posljedica tih emisija su negativni utjecaji na zdravlje ljudi i okoliš, koji ovise o količini i svojstvima otpada te načinu kojim se gospodari otpadom. Pravilan način zbrinjavanja otpada je razvrstavanje te pohranjivanje u spremnike za odvojeno prikupljanje otpada. Najčešći postupak zbrinjavanja otpada je odlaganje otpada na odlagališta. U radu je analiziran vodeni eluat sitne frakcije otpada uzetog sa Županijskog centra gospodarenjem otpada Marišćina. Rezultati su pokazali da vodeni eluat ima izuzetno visoke vrijednosti ukupnog organskog ugljika (TOC) i dušika (TN) kao i električne vodljivosti. Vrijednosti ostalih analiziranih parametara također su povišene što ukazuje na potrebu odgovornog postupanja sa otpadom jer postoji velika opasnost od onečišćenja okoliša i podzemnih voda.Waste is a substance or an object that is discarded, which is going to be discarded or that must be discarded. It is often considered to be an indicator of economic strength and development of a society. It inevitably arises as a consequence of everyday human activities and it is one of key environmental problems nowadays. Waste can cause emissions into soil, water and air, and the consequence of these emissions are negative impacts on human health and the environment, which depend on the amount and properties of waste and the way it is managed. The correct way to dispose of waste is to sort it and store it in containers for separate waste collection. The most common waste disposal procedure is to dispose of waste in landfills. This article analyses liquid eluate of fine waste fraction which was taken from a county centre for waste management Marišćina. The results showed that the liquid eluate had very high values of total organic carbon (TOC) and nitrogen (TN) as well as electrical conductivity. The values of other analysed parameters were also elevated, which indicates the need for responsible waste management because there is a high risk of environmental and groundwater pollution
