Kitinaren erauzketa tradizionala aldatu ingurumena errespetatzen duten prozesuak lortzeko

Abstract

Kitina krustazeoen exoeskeletoen propietate mekaniko nabarmenen arduraduna da eta eremu ugaritan aplikatzen ari da. Ekonomia zirkularreko kontzeptuei jarraituz, kitina hainbat biomasa-hondakinetatik berreskuratu daiteke, material horiek berriro ziklo ekonomikoan sartzeko. Hala ere, ezinbestekoa da ingurumenaren ikuspegitik jasangarriak diren bide berriak garatzea, kitina-nanopartikulen ohiko erauzketa gaindituko dutenak, krustazeo-oskoletatik abiatuta hidrolisi azidoaren tratamendu gogorrak egitea eskatzen duena, berotegi-efektuko gasen isurketak pixkanaka murriztu ahal izateko. Lan honetan sortzen ari diren alternatiba berriei heltzen diegu biopolimero hori CO2 aztarna txikian ateratzeko bide berriak eskaintzeko. Espero dugu biokoloideen alorrean planteamendu jasangarrien ezarpena bideratzea.

Chitin is responsible for the outstanding mechanical properties of crustacean´s exoeskeletons and is being applied into a plethora of fields. Following a Circular Economy approach, chitin can be valorized from several biomass wastes so these materials are reintroduced back into the economic cycle. However, it results essential to develop novel environmentally sustainable paths over the conventional chitin nanoparticle extraction involving harsh acid-hydrolysis treatments from crustacean shells so we can progressively reduce our greenhouse gas emissions. Here we tap into the new emerging alternatives to provide novel paths to extract this biopolymer at a low CO2 footprint. We hope this work guides the implementation of sustainable approaches in the field of biocolloids.
