BACKGROUND OF STUDY
Composite is the mixture of a matrix and a reinforcement, which when combined produces qualities superior to those of the separate components (Adebajo, 2022). (Adebajo, 2022). Wood plastic composite (WPC) is consequently a mixture of wood and plastic with the plastic as the matrix and the wood as the reinforcing. Wood plastic composite, (WPC), may be created from virgin resources as well as recycled ones. In Nigeria, plastic trash is massive and its disposal has long been an issue. In employing recycled plastic of WPC, the benefits are that; raw materials are easily accessible, reduce the plastic waste issue and also conserve some virgin and natural items. Substantial expansion in human population and the concomitant demand on natural resources such as forests and the accompanying adverse outcomes as well as the plastic scourge facing the country are some of the concerns that make the research of WPC crucial. The green mindset and the change in attitude are promoting environmentally-friendly goods such as WPC (Alan , 2020). (Alan , 2020). WPCs may be utilized in numerous applications such as profiles, sheathing, Decking, Roof tiles, Window trim, automobile components, stepping stones etc. Natural fibers such as wood are considered ecologically benign and sustainable owing to their renewability and biodegradability. Natural fillers offer various added benefits over artificial fibers in the sense that they have low specific weight, high specific strength and stiffness, safer handling and working circumstances;
they are also non-abrasive to the processing equipment (Azadeh, 2019). (Azadeh, 2019).Development of the oil sorbents consisting of organic waste materials was undertaken in order to supply resources for maritime oil spill response with reduced environmental burden and expense (Bandyopadhyay, 2017). (Bandyopadhyay, 2017). Sorbents of the oil spill in water are things that absorb up the oil. They may be used to recover oil via the methods of absorption and adsorption, or both. Absorbents enable oil to permeate into pore spaces in the substance they are formed of, whereas adsorbents attract oil to their surfaces but do not allow it to penetrate into the material. Once sorbents have been used to extract oil, they must be taken from the water and properly disposed of on land or cleaned for reuse. Any oil that is extracted from the sorbent materials has to be discarded or recycled once it has been done so. There are three primary categories that may be used to classify sorbents: natural organic, natural inorganic, and synthetic. Peatmoss, straw, hay, sawdust, pulverized corncobs, feathers, and other carbon-based goods are included in the first category of compostable materials. They are available for a reasonable price and, in most cases, are not hard to find. Organic sorbents have the ability to absorb between three and fifteen times their own weight in oil, although they do come with a few drawbacks. Some organic sorbents have the tendency to absorb water in addition to oil, which makes them heavier as a result. When they are spread out over the water, many organic sorbents are in the form of loose particles, such as sawdust, which makes it challenging to collect them afterwards (Bujang, 2021). Clay, perlite, vermiculite, glass, wool, sand, and volcanic ash are some examples of naturally occurring inorganic sorbents. They have the ability to soak up four to twenty times their body weight in oil. Similar to organic compounds, inorganic substances may be obtained without much trouble and at a low cost. The vast majority of organic materials, although useful on land, are not suitable for use in water and cannot be employed to clean up an oil spill. Included in the category of synthetic sorbents are man-made substances that are analogous to plastics and include polyurethane, polyethylene, polypropylene, and nylon fibers, among others. The majority of synthetic sorbents have the ability to absorb up to 70 times their own weight in oil. Synthetic sorbents that cannot be cleaned after use might be a source of complications due to the fact that they have to be temporarily kept before they can be disposed of in an appropriate manner. They are most effective in soaking up oils of lower viscosity, the kind that may permeate or wick into the fibres of the material. Absorption or adsorption are the two mechanisms that make sorbents effective (Chen, 2022). Absorbents function similarly to sponges in that they gather oil by either capillary action or suction. The effectiveness of sorbents is dependent on their huge surface area, the sorbents' chemical affinity for the spilled oil, and the sorbents' chemical ingredients, which include their porosity, molecular structure, and change in volume. While absorbents are most effective on oils that are light and have a low viscosity, adsorbents are most effective on oils that are heavy, sticky, and have a higher viscosity. In some circumstances, the same sorbent material may be used for oil recovery using both of the aforementioned methods. According to Choi., (2019), the cleanup of an oil spill is more of an issue of available alternatives than actual solutions. despite the fact that there is unlikely to be a method of oil spill cleanup that is entirely successful. One of the most common and frequently utilized approaches for cleaning up oil spills in the ocean is to employ sorbents.
The potential for absorption of waste plastic composites (WPC) generated from recovered plastic and wood waste is investigated in this research.
