Abstract

Održivi razvoj i imperativ kružnog gospodarstva, te sve veća potražnja za obnovljivim sirovinama nametnuli su potrebu istraživanja učinkovitih postupaka recikliranja proizvodnog i/ili potrošačkog otpada. Posebno se to odnosi na nove, sve prisutnije konstrukcijske materijale – biokompozite (kompozitni materijali kod kojih je najmanje jedan konstitutivni dio, vlakno kao ojačalo ili matrica, biorazgradiv ili prirodnog porijekla). Iako svaki od mogućih načina recikliranja vlaknima ojačanih kompozita (kemijski, mehanički i energetski) ima svoje prednosti i mane, kemijsko recikliranje pokazuje potencijal za oporabu, kako vlakana tako i polimera matrice. Za potrebe ovog diplomskog rada istražene su mogućnosti kemijskog recikliranja biokompozita, točnije brnistrinim vlaknima ojačanog PLA (polilaktidna kiselina) polimera, a s ciljem definiranja najdjelotvornijeg postupka, obzirom na kvalitetu oporabljenih vlakana i sveukupni utjecaj procesa na okoliš.

Abstract (english)

Sustainable development and the imperative of a circular economy, as well as the increasing demand for renewable raw materials, have imposed the need to research effective procedures for recycling production and/or consumer waste. This especially applies to new, increasingly present construction materials - biocomposites (composite materials in which at least one constituent part, fibre as reinforcement, or matrix, is biodegradable or of natural origin). Although each of the possible ways of recycling fibre-reinforced composites (chemical, mechanical, and thermal) has its advantages and disadvantages, chemical recycling shows potential for recovery of both fibres and matrix polymer. For the purposes of this work, the possibilities of chemical recycling of biocomposite, more specifically PLA (polylactide acid) polymer reinforced with broom fibres, was investigated, with the aim of defining the most effective procedure considering the quality of recovered fibres and the overall impact of the process on the environment.
