Cellulose Membranes in the Treatment of Spent Deep Eutectic Solvent Used in the Recovery of Lignin from Lignocellulosic Biomass
Ippolitov, Vadim; Anugwom, Ikenna; van Deun, Robin; Mänttäri, Mika; Kallioinen-Mänttäri, Mari (MDPI, 13.01.2022)Ultrafiltration was employed in the purification of spent Deep Eutectic Solvent (DES, a mixture of choline chloride and lactic acid, 1:10, respectively) used in the extraction of lignin from lignocellulosic biomass. The ... -
Effect of Low Concentrations of Lithium Chloride Additive on Cellulose-Rich Ultrafiltration Membrane Performance
Lopatina, Anastasiia; Esmaeili, Mohammadamin; Anugwom, Ikenna; Mänttäri, Mika; Kallioinen-Mänttäri, Mari (MDPI, 05.02.2023)Various water treatment processes make extensive use of porous polymeric membranes. A key objective in membrane fabrication is to improve membrane selectivity without sacrificing other properties such as permeability. ... -
Lignin as a functional additive in a biocomposite: Influence on mechanical properties of polylactic acid composites
Anugwom, Ikenna; Lahtela, Ville; Kallioinen, Mari; Kärki, Timo (Elsevier, 26.08.2019)In this research, lignin and modified lignin were used as a biobased additive in the manufacturing of biocomposites. The biocomposites were produced from polylactic acid (PLA) and wood. Lignin used in this study was recovered ... -
Long‑term stability of cellulose membranes in spent deep eutectic solvent used in the recovery of lignin from lignocellulosic biomass
Ippolitov, Vadim; Anugwom, Ikenna; Mänttäri, Mika; Kallioinen-Mänttäri, Mari (Springer Nature, 02.02.2024)Deep eutectic solvents (DESs) are a novel class of solvents that can be used to fractionate biomass compounds. However, their sustainability depends strongly on their recyclability. In previous research, it was seen that ... -
NADES-based fractionation of biomass to produce raw material for the preparation of cellulose acetates
Soto Salcido, Luis; Anugwom, Ikenna; Mänttäri, Mika; Kallioinen, Mari; Ballinas-Casarrubias, Lourdes (Springer, 29.05.2020)Waste biomass (agave bagasse) and native birch wood were used as raw materials for a novel fractionation and derivation process to produce cellulose acetates (CAs). During the first stage of the fractionation process, a ... -
Preparation of cellulose-rich membranes from wood: effect of wood pretreatment process on membrane performance
Lopatina, Anastasiia; Anugwom, Ikenna; Esmaeili, Mohammadamin; Puro, Liisa; Virtanen, Tiina; Mänttäri, Mika; Kallioinen, Mari (Springer Nature, 14.09.2020)In this study cellulose-rich membranes were fabricated from untreated and treated hardwood biomass solutions in 1-ethyl-3-methylimidazolium acetate ([Emim][OAc])—dimetylsulfoxide (DMSO) system via wet phase separation. ... -
Re-use of waste cotton textile as an ultrafiltration membrane
Lopatina, Anastasiia; Anugwom, Ikenna; Blot, Hervé; Sánchez Conde, Ángela; Mänttäri, Mika; Kallioinen, Mari (Elsevier, 20.05.2021)Textile industry produces millions of tons of waste annually, which is predominantly incinerated or landfilled. Cotton textile comprises a quarter of total textile production, and although being renewable, its production ... -
Wood-Based Cellulose-Rich Ultrafiltration Membranes: Alkaline Coagulation Bath Introduction and Investigation of Its Effect over Membranes’ Performance
Lopatina, Anastasiia; Liukkonen, Alma; Bec, Sabina; Anugwom, Ikenna; Nieminen, Joona; Mänttäri, Mika; Kallioinen-Mänttäri, Mari (MDPI, 31.05.2022)In this study, wood-based cellulose-rich membranes were produced with a novel approach to casting procedure. Flat-sheet membranes were prepared from birch biomass pretreated with deep eutectic solvent and dissolved in ionic ...
