dc.description.abstractThe spread of raft-farming of mussels in river estuaries around the world produces millions of tons of shell waste which mainly ends up in landfills. In addition, the United Nations and the European Union promote the sustainable development goals (SDG) for sustainable food production, requiring adequate waste management to analyse the life cycle and reuse of goods and materials. This work proposes to use mussels shells by-products created by the canning industry as abrasive in the sandblasting process. One of the main characteristics of abrasive grains is the friability, which determines the behaviour of the abrasive in the sandblasting process. Shells need to be prepared before using in sandblasting, a conditioning that involves the cleaning, grinding and sieving of shells. The purpose of this work is to examine the friability of mussel shells from two points of view, the effect of the cleaning process and a comparison with a common abrasive material (garnet). The characterization of the friability of mussel shells allows to foresee and define adequate applications according to their behaviour as abrasive. It is noticeable on the results that garnet is four times more friable than shells. This interesting feature enlarges the life of sand in close cycles and foresees a promising future to the new application.; Munduan zehar ibaien estuarioetan muskuilu-haztegiek izandako zabalkuntzak irtenbide zaila duen milioika tona maskor hondakin sortzen ditu. Bestalde, Nazio Batuek eta Europar Batasunak bultzatutako garapen iraunkorrerako helburuek (GIH) elikagaien ekoizpen jasangarria bultzatzeaz gain, hondakinen kudeaketa egokia exijitzen du, material eta produktuen bizitza zikloa aztertzera behartuz eta berrerabilpena lehenetsiz. Lan honek kontserba-industriak sortutako muskuilu-maskor azpi-produktua granailaketan eta hondar-zurrustako garbiketa-prozesuetan urratzaile gisa erabiltzea proposatzen da. Urratzaileen ezaugarri nagusietako bat hauskortasuna da, horrek baldintzatzen baitu urratzailearen portaera hondar-zurrusta prozesuan. Maskor-hondarra lortzeko pausoak maskorren garbiketa, ehoketa eta baheketa prozesuek osatzen dute. Lan honen helburua muskuilu-maskorren hauskortasuna bi ikuspuntutatik aztertzea da: garbiketa-prozesuaren eragina eta ohiko urratzaile batekin (granatea) hauskortasunaren konparaketa. Muskuilu-maskorren hauskortasunaren karakterizazioak urratzaile gisa duten portaera aurreikusi eta aplikazio egokiak definitzea ahalbidetzen du. Emaitzek nabarmenki erakutsi dute maskorrek granateak baino lau aldiz hauskortasun txikiagoa duela. Ezaugarri interesgarri horrek ziklo itxian lan egiten duen hondarraren bizitza luzatzea dakar eta aplikazio berriari hondar-zurrustan etorkizun oparoa aurreikusten dio.
