Abstract

U današnje vrijeme, brz razvoja tehnologije, nagli porasta broja stanovništva i urbanizacija, doveli su do značajnog povećanja proizvodnje otpada, što predstavlja ozbiljan izazov za moderno društvo. Raste interes za proizvodnju kemikalija iz lignocelulozne biomase i organskog otpada kao obnovljivih prirodnih izvora kako bi se smanjila količina otpada. Lignocelulozni otpadni materijali predstavljaju obećavajuću alternativu tradicionalnim rafinerijama nafte, utirući pute biorafinerijama. Biomasa se može u potpunosti pretvoriti u vrijedne kemikalije, bioenergiju i materijale, što je čini ključnom sirovinom za razvoj kružnog bioekonomskog pristupa. Korištenje biomase za proizvodnju kemikalija od velike je važnosti za održivu budućnost kemijske industrije. Uspješan razvoj biokemikalija također ima potencijal za poticanje inovacija u područjima poput novih polimera i materijala, novih otapala te bioaktivnih spojeva. Međutim, biokemijske, termokemijske i katalitičke konvencionalne metode pretvorbe biomase imaju svoje nedostatke, što naglašava potrebu za daljnjim istraživanjima i tehnološkim napretkom u ovom području. Ovaj rad daje kratak pregled tradicionalnih tehnika obrade biomase, uključujući toplinsko zagrijavanje i biokemijske procese. Detaljnije je objašnjen postupak obrade biomase potpomognut mikrovalovima, relativno nedovoljno korištenom metodom s potencijalom da postane ključna tehnologija u budućnosti.

Abstract (english)

In recent years, rapid technological advancements, population growth, and urbanization have led to a significant increase in waste generation, posing a serious challenge to modern society. In response, there has been growing interest in producing chemicals from lignocellulosic biomass and organic waste, utilizing these renewable natural resources to mitigate waste accumulation. Lignocellulosic waste materials offer a promising alternative to traditional oil refineries, paving the way for biorefineries. Biomass can be fully converted into valuable chemicals, bioenergy, and materials, making it crucial resource for promoting a circular bioeconomy. The use of biomass for chemical production is essential for ensuring the sustainability of the chemical industry's future. Furthermore, the successful development of biochemicals has the potential to drive innovations in fields such as new polymers, materials, solvents, and bioactibe compounds. However, conventional methods of biomass conversion whether biochemical, thermochemical, or catalytic have limitations, underscoring the need for further research and technological advancments in this area. This work provides a brief overview of traditional biomass processing techniques, including thermal heating and biochemical processes. It then delves into microwave-assisted biomass processing, a relatively underutilized method with the potential to become a key technology in the future.
