“…Furthermore, in recent times the plastics industry uses renewable raw materials not only for the sustainability and marketing aspects of the products but because they could improve the chemical–physical and mechanical properties of the final PUR product (Lossada et al, 2019; Nanda et al, 2022; Shoukat et al, 2022). Beyond that, various research and development sectors, such as water purification, employ natural materials to replace synthetic ones, to obtain composite materials with high performance and low environmental impact (Olivito et al, 2021; Tursi et al, 2020, 2021, 2022).…”

The present study investigated if new biocomposite materials, polyurethanes (PURs) added with functionalized cellulose fibers, produce potential toxic effects on two target organisms currently used in biomonitoring the quality of two different environmental compartments. Natural fibers were extracted from the species Spartium junceum L., a shrub commonly found in the southern region of the Mediterranean having a high cellulose content. All PURs produced were characterized by Fourier-transform infrared spectroscopy, and their structure was analyzed by scanning electron microscopy. We measured the effects of exposure to aromatic and aliphatic PUR composites (containing or not cellulose fibers) on the aquatic model organism Daphnia magna Straus, a freshwater crustacean (Cladocera), and a biomonitor of air quality, the fruticose epiphytic lichen Pseudevernia furfuracea (L.) Zopf. Leachates from aliphatic PUR composite not containing cellulose are more toxic to D. magna than all others, showing a slight acute toxicity in the case of the shortest exposure (24 h) and a moderate acute toxicity in the longer one (48 h). This effect is most likely due to the presence of free organic ammines and amides, which, in their turn, are immobilized in composites containing cellulosic fibers because of the considerable amount of chemical functional groups. Regarding lichens, both types of aliphatic PURs resulted in a toxic effect. Formulate not added with cellulose strongly promoted fungal peroxidation, whereas that which was functionalized affected the pigment concentration of the algal partner. Our results suggest that the use of cellulose in PUR production, in general, can limit the ecotoxicological effects on both test organisms and reduce the potential environmental impact due to this type of polymer.

“…Among the natural sorbent, cellulose was used in recent years to remove different kinds of pollutants from waters such as hydrocarbons, dyes, heavy metals and others because of both its hydrophobic core and its hydrophilicity due to the hydroxyl groups [ 27 , 28 , 29 ]. Cellulose and its derivatives can also be used as additives or reagents in polymerization reactions to replace non-renewable chemicals and create bio-based materials [ 30 , 31 , 32 ].…”

In this paper, we evaluated the potential of two synthesized bio-based polyurethane foams, PU1 and PU2, for the removal of diesel and gasoline from water mixtures. We started the investigation with the experiment in batch. The total sorption capacity S (g/g) for the diesel/water system was slightly higher with respect to gasoline/water, with a value of 62 g/g for PU1 and 65 g/g for PU2. We found that the sorption follows a pseudo second-order kinetic model for both the materials. The experimental data showed that the best isotherm models were obtained with Langmuir and Redlich–Peterson models. In addition, to provide an idea of the process scalability for future industrial applications, we tested the sorption capacity of the foams using a continuous-flow of the same oil/water mixtures and we obtained performances even better with respect to the batch test. The regeneration can be performed up to 50 times by centrifuge, without losing efficacy.

“…The dried and crushed cellulose residues of E. crassipes are an alternative because they have around 70% cellulose, and it is a somewhat expensive residue for final disposal 1,4. The aquatic plant, E. crassipes, expands on the surface of water bodies, creating a layer that limits the transfer of oxygen into the water, affecting ecosystems [8][9][10][11][12] .The transformation of cellulose with carbon disulfide (CS 2 ) forms cellulose xanthogenate, which is an alkaline biomass charged with ions (OH − ) that allows easy chemisorption of metal cations from industrial wastewater 13,14 . The used the xanthogenate of cellulose was implemented for eliminated Cr (VI) 15 .The tests to determine the removal efficiencies of heavy metals through this type of biomass are generally carried out in batches, a condition under which the removal efficiencies, adsorption capacities and adsorption kinetics obtained 16 .…”

Water care is an imperative duty in industries with effluents loaded with pollutants such as heavy metals, especially chromium (VI), extremely dangerous for humans and the environment. One way of treating water is possible through a continuous system with dry and crushed vegetable biomass of cellulose xanthogenate because it can adsorb heavy metals, especially due to its low production costs. Through continuous systems and with the waste of PET plastics, it is possible to develop a water treatment process adapting this system and biomass. The objective of this research is the development of a treatment for water contaminated with Cr (VI) using cellulose xanthogenate from E. crassipes on a pilot scale. Where a mass balance conducted to determine the adsorption capacity of this heavy metal, corroborating it through the Thomas model. The treatment process eliminated around 95% of Cr (VI) present in the water, in addition, biomass reuse cycles carried out, which maintained a considerable adsorption capacity in all the cycles conducted through EDTA reagent.
