Sažetak

This review paper analyzes the possibility of using the perennial crop of Virginia mallow (Sida hemaphrodita (L.) Rusby) to produce cellulose fibers. This culture was chosen, due to the previously established multiple applications, which, in addition to cultivation for food and medicinal purposes, include cleaning of the soil, increasing biological diversity, reducing soil erosion, and even the production of biofuels. The primary goal of this research was to determine the possibility of using the biomass (stems) of this plant for fiber production, that is, to determine the optimal conditions for fiber isolation. In cooperation with experts in the agricultural profession, the possibility of using the solid residue for energy purposes was examined. In the pretreatment process, the success of the combination of physical/chemical fiber treatment with the use of microwave energy was established, which not only shortens production time and energy consumption but also contributes to the ecological and economic aspects of fiber processing. The results of the conducted research confirmed the possibility of multiple applications of Virginia mallow biomass, first for fiber isolation, and then for the production of solid or liquid biofuels. The results indicate the possibility of revitalizing the mallow plant while meeting the goals of the circular bioeconomy and the European Green Deal, which is crucial for facing the challenges of climate change.
