Development of cellulose based aerogel utilizing waste denim-A Morphology study.
Cellulose aerogels with orientated micron-sized pore structure were obtained from denim waste utilizing ionic liquid solvents through dissolution, regeneration and drying. The pore structure of denim-derived aerogels was comprised of a mixture of micron-sized vertically aligned pores and a nanoporous fibrous network. The size and distribution of vertically aligned pores and the nanopores were influenced by the choice of ionic liquid solvent, amount of denim used and drying method employed. A detailed study on the morphology of the cellulose aerogels produced from waste denim is provided.

Pretreatment of eucalyptus with recycled ionic liquids for low-cost biorefinery.
It is urgent to develop recycled ionic liquids (ILs) as green solvents for sustainable biomass pretreatment. The goal of this study is to explore the availability and performance of reusing 1-allyl-3-methylimidazolium chloride ([amim]Cl) and 1-butyl-3-methylimidazolium acetate ([bmim]OAc) for pretreatment, structural evolution, and enzymatic hydrolysis of eucalyptus. Cellulose enzymatic digestibility slightly decreased with the increased number of pretreatment recycles. The hydrolysis efficiencies of eucalyptus pretreated via 4th recycled ILs were 54.3% for [amim]Cl and 72.8% for [bmim]OAc, which were 5.0 and 6.7-folds higher than that of untreated eucalyptus. Deteriorations of ILs were observed by the relatively lower sugar conversion and lignin removal from eucalyptus after 4th reuse. No appreciable changes in fundamental framework and thermal stability of [amim]Cl were observed even after successive pretreatments, whereas the anionic structure of [bmim]OAc was destroyed or replaced. This study suggested that the biomass pretreatment with recycled ILs was a potential alternative for low-cost biorefinery.
