Separation/stabilization of selected heavy metals from water and soil using waste seashells

Ubrzani industrijski razvoj doveo je do globalnih problema iscrpljivanja prirodnih resursa, zagađenja životne sredine, generisanja i akumulacije otpada. Ljušture školjki, poreklom iz prehrambene industrije, koje se u milionima tona generišu svake godine, deponuju se u priobalnim područjima gde negativno utiču na celokupnu životnu sredinu. Kao sekundarni izvor kalcijum karbonata, ovaj materijal predstavlja potencijalnu zamenu za prirodni krečnjak, čija je dostupnost ograničena. Otpadne ljušture školjki imaju široku primenu u oblastima kao što su: tretman vode i zemljišta različitog stepena zagađenja, ishrana domaćih životinja, proizvodnja gume, boja, farmaceutskih proizvoda...Global industrial development has led to the fast depletion of natural resources, environmental pollution, and waste generation and accumulation. The seafood industry generates millions of tons of mollusc shells, which are deposited in coastal areas with negative effects on the entire environment. As a secondary source of calcium carbonate, seashells are a potential substitute for limestone, which availability in nature is limited. Waste seashells are already being applied in different areas, such as wastewater and soil treatment, animal feed production, pharmaceuticals, paint, and rubber production..
