AB  - Urea-based graphitic carbon nitride (g-C3N4) is thermally exfoliated at 500 °C in the air
atmosphere, and nano-carbon nitride (n-C3N4) is obtained. While optical properties are assessed
using UV/Vis DR spectroscopy, structural and morphological parameters of two materials are
obtained using XRD, TEM, and FTIR. Flat-band potentials were determined from Mott-Schottky
plots, and combined with corresponding band-gap energies, to estimate conduction and valence
band potentials of both materials. Photocatalytic efficacy of both semiconductors in photocatalytic
degradation of three textile dyes under simulated solar light irradiation is compared, with the
conclusion that n-C3N4 expressed higher photocatalytic ability in the studied systems. Finally, in
order to provide reusability of the semiconductors in multiple consecutive photocatalytic cycles,
both photocatalysts were drop-coated on the jute-based post industrial waste. Reusability of juten-C3N4 material is probed in three consecutive photocatalytic cycles, and the obtained results
showed that this material can have a future in solving real-life environmental problems.

AB  - Intensified oil exploitation accompanied with frequent oil spills having a detrimental impact on ecosystems are seeking efficient, environmentally and economically feasible solutions. In an attempt to develop an efficient, reusable, biodegradable and cheap sorbent for oil clean-up non-woven sorbents based on recycled jute post-industrial textile waste were fabricated. The influence of area density of non-woven sorbents and hydrophobicity of fibers on overall oil sorption performance was the focus of this research. All sorbents showed a good reusability after five sorption cycles and buoyancy in water even after 24 h independently of sorbent structure. The area density of sorbents and viscosity of studied oils (crude oil, diesel oil and two types of motor oils) highly affected the oil sorption capacity and oil retention. The sorbent with the lowest area density exhibited the best oil sorption performance. The esterification of jute with stearic fatty acid contributed to decrease in water uptake of sorbents but also to negligible change of oil sorption behavior indicating that the structure of the sorbent in this case plays a crucial role.

AB  - Loose assemblies of cellulose fibers could be employed in the clean-up of oil spills, but the difficulty to separate them from the spill after use makes them impractical. In an effort to tackle this issue, a non-woven sorbent based on recycled jute fibers from the carpet industry was developed. To enhance the porosity and hydrophobicity/oleophilicity of the sorbent, carbonization in an inert atmosphere was carried out. A comparison in oil sorption performance between non-carbonized and carbonized sorbents was made by evaluating the oil capacity in a water medium, buoyancy, oil retention and reusability. Carbonization of sorbent resulted in more than doubled oil sorption capacity independent of oil viscosity. Oil viscosity did not affect the oil sorption capacity of non-carbonized sorbent. Carbonized sorbent showed superior buoyancy in water even after 24 hours, oil retention of approximately 60–80% after 3 hours and only 12–20% decline of oil sorption capacity after five repeated sorption/desorption trials. However, the ability of oiled non-carbonized sorbent to efficiently biodegrade in model compost (up to 45% weight loss after 10 weeks) makes it a sustainable candidate for oil spill clean-up.

AB  - Over 90 million tons of textile waste is produced every year. A large share of waste comes from the goods made of cellulose fibers. Recently, special attention has been directed towards the use of textile cellulose waste for clean-up of oil spills. The major problem relies on their relatively small oil capacity and complex separation of individual cellulose fibers from the treated spills. In an attempt to overcome this drawback, a non-woven sorbent based on recycled jute fibers obtained from the carpet industry was manufactured. Improvement of porosity and hydrophobicity/oleophilicity of the sorbent was achieved by carbonization process in an inert atmosphere. FESEM analysis revealed the fiber reduction of almost 40% induced by fiber degradation while EDX analysis confirmed the increase in the carbon content by 75% after carbonization. Oil capacity in water medium, buoyancy, oil retention and reusability of non-carbonized and carbonized sorbents were evaluated by testing four different oils (crude oil, diesel oil, two motor oils). After carbonization process, the oil sorption capacity was doubled in comparison with noncarbonized sorbent independent of oil viscosity. Carbonized sorbent not only remained afloat after 24 h of staying in water, but it sorbed a negligible amount of water unlike non-carbonized sorbent. in addition to good buoyancy, oil retention on carbonized sorbents ranged from 64-80% after 30 min of draining. Larger uptake was achieved with oils of higher viscosity, but their retention was worse. Oil sorption capacity after 5 repeated sorption/desorption trials was significantly larger in the case of carbonized sorbent since it retained 80-88% of its initial oil sorption capacity depending on tested oil.
