“…Phase-selective gelation using a mixture of seawater (prepared) 36 and PBCO was attempted multiple times, with each trial resulting in the crude oil phase being preferentially gelled with M-8 at 5% (w/v). This further strengths the applicability of these PSGs for practical crude oil spill remediation in the harsh environmental conditions like saltiness.…”

In this work, we demonstrate the use of biomass for the catalytic production of phase-selective gelators (PSGs) as a cost-effective, environmentally benign and ideal method for crude oil spill remediation, as well as execute the study exclusively in crude oil. The use of PSGs has recently provided great promise relative to that of their traditional counterparts. However, the use of PSGs with crude oil is much more complicated due to its complex composition. All of the current PSG methods are demonstrated with refined oils or do not employ eco-friendly methods like enzymatic synthesis. Our current project entails studying sugar alcohol-derived amphiphiles for their phase-selective gelation in crude oil; the PSGs are derived from renewable, benign materials and synthesized via a simple, single-step, enzymatic catalysis that required no purification. The results showed that, after a rigorous and systematic testing, the mannitol-derived amphiphile using 8-carbon alkyl chain length (M-8) turned out to be the best crude oil PSG among the studied amphiphiles. M-8 demonstrated a versatility towards thickening of different crude oil types, an efficient ability towards selective gelation of the oil (forming crude oil gel that is over sixty-one-times its mass and stable up to 109.7 °C) in a crude oil/water mixture, and an ability to form gel under practical situations such as seawater conditions. These qualities, in addition to the use of a simple and environmentally benign method to synthesize the structuring agents, make this amphiphile very practical in real life application.

“…This is because this type of plants has wax in their body. This waxy structure makes them able to float in the water (Gupta et al 2015;Al-Majed et al 2012). Barley, oats, wheat, rice straw, and rice husk all come under organic sorbent biomaterials as mentioned above Table 1.…”

Study of bio-materials for removal of the oil spill

The major battle that the human civilization is facing in the present era is regarding pollution; one of a serious threat among these pollutions is the contamination of water bodies due to oil spills. Oil spills from ships, tankers, or leaks in marine oil pipes are something that is needed to deal with to make the earth a better place. To protect the water and the environment, this oil should be removed from the water or the surface. The chances for oil spills have reduced as we have observed there is a significant change in the pattern with the decrease of the use of tankers and pipelines for oil and petroleum derivatives. The point should be that according to the researchers, the marine ecosystem is damaged even more by the other sources of pollution even though the event of oil spills is certainly much sensational. There is an urgent requirement of advanced eco-friendly tools to eliminate spilled oil. Some studies suggest that the use of organic matter may be an effective step in such an oil spilled scenario. Organic matter acts as a sorbent, a surfactant, and a separator and can make using a variety of ingredients such as organic, inorganic, synthetic, or different, but they must interact with the biological system. Some organic materials can contaminate the water more than the oil that is spread, so eco-friendly, non-toxic, low-cost organic matter should be used for oil removal and recovery. If the oil is recovered from the environmental surface, then after the successful removal of that oil, it can be conducive to sustainable development. This review summarizes the overall perspective on the potential of different biomaterials for the removal of accidentally spilled oils.

“…We as a human cannot avoid mistakes or accidents but we can reduce or control the harmful outcomes after such accidental oil spills. To overcome such scenarios in case of oil spills, techniques like skimming, burning, use of booms, use of chemical dispersants and solidifiers are being practiced.…”

Biomass‐Derived Lignocellulosic Graphene Composite: Novel Approach for Removal of Oil and Organic Solvent

et al. 2019

Novel approach to develop a biomass derived lignin‐cellulose based, ultra‐light, hydrophobic graphene supported spongy composite was synthesized to absorb oil and organic solvents from wastewater. Spongy composite was synthesized by a facile and highly efficient one‐pot hydrothermal method from the natural precursor. Lignin‐cellulose functionalized graphene (LCG) sponge was synthesized from graphene oxide (GO) and sugarcane waste powder (SCwP) in presence of natural latex. LCG successfully demonstrated separation of oil from oil‐water mixture. LCG has high oil sorption capacity in the range of 25–50 g of oil per gram of sorbent. This material showed high efficiency as a sorbent to separate organic chemicals from wastewater. The absorption capacity of LCG sponge was enhanced thrice in comparison with SCwP and could be reused up to 10 cycles. The continuous oil water separation process was demonstrated using LCG sponge from the oil‐water mixture, which can be applied for large scale oil recovery from the waste stream.
