Abstract
Water pollution by hydrocarbon derivatives is one of the significant problems and challenges globally and is one of the leading causes of disease and environmental catastrophes. Increasing oil effluents have become a primary global concern due to damage to living ecosystems and marine life. This oil should be removed from the water or the surface to protect the water and the environment. One of the most important remedies for oil spills is using sorbent materials. Conventional synthetic sorbents for oily water treatment are the most broadly applied materials, although they are not the optimal selection from environmental and economic points of view. However, the utilization of biobased sorbents derived from natural materials with environmentally friendly, low-cost, reusability, abundant, and biodegradability properties can be an ideal alternative for convectional synthetic sorbent, with a positive effect on sustainability and circular economy. These types of sorbents are used with various sizing from micro to nanoscale in different forms (membrane, aerogel, foam, and sponge). The objective of this paper is to review a report on the use of porous biobased sorbents in both natural and modified forms which are available in nature or our lives. Modification strategies for improving hydrophobicity of biobased sorbent were also broadly highlighted. Finally, the challenges and future research directions of this promising research field are briefly discussed.
