Summary: This study proposed an integrated process involving deep eutectic solvent (DES) pretreatment, mechanical refining, and enzymatic hydrolysis to refine bleached kraft pulp into dissolving pulp and co-produce two xylo-oligosaccharides. The technique successfully achieved high-purity dissolving pulp with improved cellulose reactivity, while also producing high-quality XOS product streams.

Summary: Enzymatic processes offer energy-efficient and reagent-saving alternatives to traditional chemical routes in the production of dissolving pulp for regenerated cellulosic fibres. Enzymes can control the purity and molecular weight of dissolving pulp, with endoglucanases effectively reducing cellulose molecular weight and increasing reactivity for viscose production. Additionally, lytic polysaccharide monooxygenases synergistically modify bleached dissolving pulp along with endoglucanases, showing promising results for pulp quality improvement.

Summary: In this laboratory study, hardwood bleached kraft pulp was converted to dissolving pulp by removing hemicellulose using organic electrolyte solutions. The optimal conditions led to a dissolving pulp with a yield of 76%, cellulose content of 91%. The study also explored the potential of selectively removing hemicelluloses using a ternary system.

Summary: This study assesses the possibility of obtaining regenerated cellulose products from eucalyptus sawdust dissolving pulps produced by non-conventional processes and compares them with a commercial dissolving pulp. The experiment shows that eucalyptus sawdust dissolving pulps are suitable raw materials for regenerated cellulose products. Furthermore, a certain process for preparing the dissolving pulp was found to be more economical and direct.

Summary: This research uses process simulations to generate life cycle inventory data for different grades of dissolving pulp (DP) and finds that biomass feedstock directly affects the environmental impacts of DP. The study shows that hardwood acetate grade has a higher global warming potential compared to softwood acetate, but lower impacts in other categories related to ecosystems and human health.

Summary: Due to the declining sustainability of cotton, lignocellulosic materials are being used to produce dissolving pulp for textile applications. Pre-hydrolysis kraft is a main process used, but the majority of hemicelluloses end up as xylose and furfural, traditionally burned. This study aims to recover xylooligosaccharides (XOS) and evaluate the effect of pre-hydrolysis conditions on pulp characteristics.

Summary: In this study, CNFs were prepared from pre-hydrolyzed eucalyptus raw materials, and the impact of prehydrolysis conditions on the micro-structure of CNFs was investigated. Higher prehydrolysis temperature led to increased crystallinity of CNFs, while prolonged prehydrolysis treatment resulted in the formation of numerous nanopores on the surface of CNFs by breaking hydrogen bonds.

Summary: In this work, an ultrafast microwave-assisted deep eutectic solvent (MW-DES) process was proposed for viscosity control and reactivity enhancement in the production of high-quality cellulose products. The MW-DES process achieved simultaneous fiber swelling and cellulose depolymerization, resulting in a significant decrease in pulp viscosity and increase in reactivity. The DES used in the process showed high reusability and chemical stability, providing a simple, sustainable, and effective alternative for upgrading dissolving pulp from non-wood materials such as bamboo.

Summary: The aim of this study was to investigate the application of plasma activated water (PAW) in barley steeping to reduce the concentration of deoxynivalenol (DON) in naturally infected barley (NIB). Results showed that a 30-min PAW treatment significantly reduced DON compared to control, and the beta-amylase activity in PAW treated barley malt was higher. The study suggests the potential application of PAW for barley steeping to reduce DON without influencing germination and quality.

Summary: This paper proposes a new xylanase-assisted activated carbon process for producing high-purity sugar from the pre-hydrolysis liquid (PHL) in kraft-based dissolving pulp production. The enzymatic hydrolysis improves lignin removal and sugar purity. Cleavage of lignin-carbohydrate complex (LCC) by enzymes leads to more sugar and soluble lignin production. The induced soluble lignin can be effectively adsorbed by activated carbon without blocking its pores.
