dc.description.abstractLight olefins (especially, ethylene and propylene) are the key building blocks of the petrochemical industry and they are mainly used to produce polyolefins (polyethylene and polypropylene). Nowadays, light olefin demand is continuosly increasing, where ethylene demand shows an annual average rate of 3-5% and propylene of 5-7%. Ethylene demand is satisfied by ethane steam cracking (SC) process. However, in order to fulfill the propylene demand, the selectivity achieved by conventional technologies (SC and fluid catalytic cracking (FCC)) should be improved. Furthermore, these industrial technologies show a great dependence on fossil fuels and a high energy consumption.Thus, improving these conventional technologies, as well as developing alternative processes based on rewenable sources are the main challenges for the refineries and the petrochemical industries. In this work, the main applications of light olefins and their worldwide demand are firstly analyzed. Then, the conventional technologies (from fossil fuels) are described; and, finally, other sustainable techonologies are discussed, which are based on the valorization of biomass and wastes.; Olefina arinak (bereziki, etilenoa eta propilenoa) industria petrokimikoko oinarrizko lehengaiak dira eta poliolefinak (polietilenoa eta polipropilenoa) ekoizteko erabiltzen dira nagusiki. Gaur egun, olefinen eskaria handituz doa: etilenoaren eskariak urteko % 3-5eko igoera izan du, eta propilenoak, aldiz, % 5-7koa. Etilenoaren eskaria bermatuta dago etanoaren ur-lurrun bidezko cracking termiko (SC) prozesuaren bitartez, baina propilenoaren eskaria betetzeko, ohiko prozesuek (SC eta cracking katalitikoa ohantze fluidizatuan (FCC)) eskaintzen duten hautakortasuna hobetu beharra dago. Gainera, industria-mailan ezarritako teknologiek erregai fosilen mendekotasun eta energia-kontsumo handia dute. Beraz, ohiko teknologiak hobetzea eta iturri berriztagarriak erabiltzen dituzten prozesuak garatzea dira gaur egungo findegiaren eta industria petrokimikoaren erronka nagusiak. Artikulu honetan, lehendabizi, olefina arinen erabilerak eta haien eskaria mundu-mailan aztertuko dira. Jarraian, ohiko teknologiak deskribatuko dira (iturri fosiletik abiatuz) eta, azkenik, bestelako teknologia berriztagarriak aurkeztuko dira, biomasaren eta hondakinen balorizazioan oinarritzen direnak.
