“…Table 2 compares temperatures and percentages of significant snail shell loss with other works. The results obtained are coherent with Shafu Kamba et al [19], Egreric et al [5], and Redouane et al [11]. In the same sense, Fombuena et al [20], found the weight loss of shellfish from different mollusks close to 42% at 817℃.…”

“…In the same sense, Fombuena et al [20], found the weight loss of shellfish from different mollusks close to 42% at 817℃. Also, Egeric et al [5] have reported a decrease of 45.1% at 900℃. In addition, Redouane et al [11] studied and characterized Moroccan snail shells and found that the significant loss is situated at a temperature of 835℃ with a percentage of 40.18%.…”

“…Another study evaluates the feasibility of using snail shells from industrial waste to remove copper ions Cu 2+ . This study is based on the effect of thermal pretreatment in the range of 300℃ to 900°C on the adsorption of copper ions [5]. Also, studies have been done on the kinetics of wastewater treatment in the brewing industry using snail shell particles [6].…”

Natural particles are the most abundant resources exist in nature. Bio-sources of CaCO3 particles have attracted the attention of researchers for multiple cosmetics, industrial, and medical applications. This work investigates the structural evolution of CaCO3 containing in snail shell particles prepared by a mechanochemical process using methods of characterization as well as Differential scanning calorimeter (DSC), Thermogravimetric analysis (TGA), X-ray diffraction (X-RD), Fourier transformation infra-red (FT-IR), and Scanning microscopy equipped with Energy-dispersive X-Ray spectroscopy (SEM-EDXS). The result obtained from the above analysis indicates that SSP calcined between 200℃ to 400℃ undergoes an elimination of water molecules, followed by a phase transformation from Aragonite to CaCO3 Calcite. At 800℃, the SSP decomposes CaCO3, giving rise to calcium oxide crystals CaO, which release CO2 molecules. These eliminations and transformations represent a loss of 47.08% of the initial mass at 800℃. The morphological analysis shows the surface of SSP calcined at 800℃ with CaO/CaCO3 crystal formation. Also, the mechanochemical process leads to obtaining an SSP with a size between 3.311 µm to 10.140 µm. Snail shells can be a natural source of CaCO3 and CaO, thanks to their ease of extraction and processing.

“…Upotreba otpada morskih školjki ublažila bi i ekološke probleme akumulacije ove vrste otpada u priobalnim područjima, posebno neodređenog (nespecifičnog) otpada školjki [33]. Neka od ispitivanja na ovom otpadnom materijalu obuhvatila su određivanje efikasnosti sorpcije Cu 2+ , Zn 2+ , Pb 2+ i Sr 2+ [33], kao i ekstrakciju Cu 2+ jona iz sintetičkih rastvora i otpadnih voda [34]. Nespecifični otpad školjki pokazao je različitu selektivnost u odnosu na ispitivane katjone.…”

“…Pored vrste školjki, pokazano je da maksimum sorpcije zavisi i od eksperimenih uslova kao što je veličina čestica sorbentnog materijala [33]. Količina i granulacija otpada školjke, kao i njihove interakcije, generalno predstavljaju najuticajnije faktore, kao i pH vrednost rastvora [34]. Takođe, termičkom obradom ljuštura školjki na temperaturama višim od 700°C i primenom ovako modifikovanih sorbenata omogućeno je efikasnije uklanjanje Cu 2+ usled raspadanja kalcita do kalcijum oksida [34].…”

Trend istraživanja sorpcionih karakteristika raznih prirodnih materijala, odnosno lako dostupnih sirovina, nus-proizvoda ili otpada iz raznih vrsta industrije poslednjih godina je sve više izražen. Upotrebom otpadnih materijala smanjuje se iskorišćenje prirodnih neobnovljivih resursa i/ili iskorišćenje raznih vidova energije za sintezu ili modifikaciju prirodnih sirovina i veštačkih materijala. Takođe, korišćenje otpadnih materijala kao sorbenata izuzetno je prihvatljivo s aspekta zaštite životne sredine s obzirom da utiče na smanjenje količina ovakvih vrsta otpada, troškova njihovog odlaganja i umanjenje opasnosti od hazarda koje neki od ovih otpada potencijalno mogu da izazovu u životnoj sredini. U ovom radu dat je pregled savremenih istraživanja otpadnih materija u imobilizaciji radionuklida i teških metala. Studije su pokazale da korišćenje otpadnih materijala u procesu sorpcije, odnosno kondicioniranja tečnog radioaktivnog otpada i prečišćavanja otpadnih voda može da predstavlja vrlo efikasne i ekonomski isplative alternative standardno korišćenim metodama, odnosno sorbentima. Nedavna istraživanja o primeni različitih otpadnih materijala i nezahtevnih tehnika njihove modifikacije u cilju poboljšanja procesa sorpcije obuhvataju širok spektar otpadnih materijala, kao što su razne vrste muljeva, šljake, elektrofilterskog pepela, biomase, otpada iz prehrambene industrije, građevinskog otpada i sl.
