The spill of crude oil products into the environment has a negative impact on the ecosystem. Sorption materials are utilized as the means of their elimination. The sorption capacity of selected organic and inorganic natural sorbents, such as needles (Larix decidua, Abies alba, and Pinus sylvestris), sawdust from logging (Fagus sylvatica, Picea abies), leaf residues (Fagus sylvatica), moss (Ceratodon purpureus), soil, and synthetic sorbents Absodan Plus, expanded perlite, Eco-dry plus, and Reo Amos were all tested according to the standard ASTM F726 (2012). The natural sorbents were tested at various moisture contents (wet, air-dry, and dry) ranging from 0 to 82%. The pollutant used in the experiment was the low-viscosity engine oil 10W 40. The best sorption capacity among the wet sorbents was achieved with larch needles (11.1 g/g). Moss exhibited the best sorption capacity (25.2 g/g) among the air-dry sorbents. Regarding air-dry sorbents, larch needles, spruce sawdust, and beech sawdust showed the best results. When further dried, their sorption capacity decreased. Soil was the least efficient natural sorbent with a sorption capacity that ranged from 0.45 to 3.82 g/g. The best sorption capacity of 11.5 g/g among the synthetic sorbents was in Reo Amos. The sorption capacity of natural and synthetic substances was comparable.

“…Some strategies as chemical modification of the fibers or membrane hydrophobization post-treatment are successfully applied to overcome water plasticizing effect in cellulose absorbents. Chemical vapor deposition (CVD) based on sylanes [11,12], grafting with polystearylmethacrylate [14] and treatment with sodium docecylsulfate [10] are among the most successful and recent approaches. However, some of these treatments, mainly the ones with sylanes have some drawbacks on the cost involved in the membrane production.…”

“…However, a balance between porosity and mechanical integrity has to be achieved aiming at better effectiveness of the absorbing material [1]. The majority of the studies present a top down strategy, i.e., fibrillation of cellulose fibers until nanoscale in order to produce CNF (cellulose nanofibrilated) followed by a production of an aerogel by freeze-drying [10][11][12]14]. The obtained porous material, after been hydrophobized by any given method, has outstanding absorbent properties but this strategy stucks on the scalability of the process.…”

Oil spills and oil/water wastewater are among the great concerns regarding oil pollution. Existing technologies face many limitations and in some cases are responsible for causing secondary pollution, therefore there is as seek for environmental friendly solutions. Biomass, from which celluloses are highlighted, are being employed for oil/water separation or oil absorbents membranes. Usually, these membranes are obtained by freeze drying of CNF (cellulose nanofibrils) suspensions followed by chemical modification for hydrophobization, which involves expensive process as chemical vapor deposition and expensive reactants as sylanes, turning these processes hardly scalable. Here, we produced a natural porous structure paper from eucalyptus pulp fibers modified by a dipping and heating process in a blocked diisocyanate solution. After the surface treatment, contact angle with water reached 144°and water absorption reduced seven times, keeping the good oil absorbance. The chemical modification process is simple to be performed and use a very low quantity of reactant estimated to be less than 0.1 wt% based on cellulose. The good mechanical properties of the material allows its use in non usual conditions which can be of great importance depending on the environmental conditions.

“…Since cellulose is biodegradable, renewable, and biocompatible, its derivatives are used for many applications including the optical films, pharmaceuticals, textiles, foodstuffs, as well as the formation of cellulose composites with synthetic polymers and biopolymers (Khan et al 2016). Its application on absorption materials have been researched by many scholars and researchers (Chen et al 2015;Mulyadi et al 2016).…”

In the conventional pulp and papermaking process, lignin in black liquor is mostly burned for energy. It has not been widely used as a functional polymer. To use both cellulose and lignin component, unique kraft cooking conditions were used in bamboo cooking in this study, and acid precipitation was used to extract lignin from the black liquor. Under different pH values, the precipitated lignins were characterized and compared by gel permeation chromatography (GPC), dynamic light scattering (DLS), and Fourier transform infrared spectroscopy (FTIR). Lignin dissolution in acidic conditions was studied. Pulps with high lignin content were used to synthesize oil absorption materials, which were prepared by grafting butyl methacrylate (BMA) onto the cellulose chain. Sodium silicate was used as an initiator, and 1,4-butane dioldimethacrylate (BDDMA) was used as a crosslinker. The structures of grafted copolymers were characterized by FTIR, scanning electron microscopy (SEM), and thermogravimetry (TG). The acid precipitation process was found to be effective and has important implications for the further lignin applications. The grafting reaction between pulps and BMA was successful. The silicone oil absorption capacity of the obtained materials was 15.3 g/g.
