“…In a study by Lu et al [7], it was reported that the consistent transportation requirements and disposal of municipal solid waste caused consistent increase in the road network degradation as well as reducing the structural integrity of the soil. Hence, improving the standard quality of the road network is an essential need.…”

“…According to Merchanet al [7], the production of plastic has grown tremendously due to the increasing demand by industries like medicals, pharmaceuticals and packaging industries. Thus, the reason behind the massive plastic waste generation could then be attributed to the following: ➢ Increase in world production of plastic if 200 fold which commenced from 1950 to 2014.…”

Plastic waste is one among the numerous waste that is harmful to the environment and is been established to have a significant dominance among the industrial waste. A critical problem is in how to discard the waste plastic which is quite difficult because its non-biodegradability. Similarly, improving the sustainability of manufacturing industry and the overall circular economy remain a major challenge to the global economy. Thus, this study focused on the existing literatures on thedeployments of waste plastic in road construction. From the literature consulted, it was discovered that the incorporation of the waste plastics into the building materials like bitumen depends on the economical, ecological and technical requirements. However, adequate application of the waste plastics in road construction will provide roads and pavements with adequate rheological properties and reliability. Also, it will minimize the problem of dumping of waste plastics on the landfills that could pose threat to the environment. Thus, bringing a sustainable circular economy. This study provides a hub of information that will guide the government and other authorities on the need to develop policy that will guide the use of waste plastic in road construction without compromising the standard quality of road required.

In order to improve the comprehensive utilization rate of industrial solid waste and the road quality, a novel low-carbon and environmental friendly soil stabilizer is proposed. In this study, steel slag (SS), carbide slag (CS), blast furnace slag (BFS), fly ash (FA), and desulfurized gypsum (DG) were used as raw materials to develop a multiple industrial solid waste-based soil stabilizer (MSWSS). The optimal mix ratio of the raw materials determined by D-optimal design was as follows: 5% SS, 50% CS, 15% BFS, 15% DG, and 15% FA. The 7-day unconfined compressive strength (UCS) of MSWSS-stabilized soil was 1.7 MPa, which was 36% higher than stabilization with ordinary portland cement (OPC) and met the construction requirements of highways. After 7 days of curing, the UCS of MSWSS-stabilized soil was significantly higher than that in the OPC group. X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) analysis indicated that the prominent hydration products were ettringite (AFt) and C-S-H gel. The results showed that an amount of AFt and C-S-H were formed in the initial stage of curing, resulting in a rapid improvement in early UCS. As the curing proceeded, the content of AFt and C-S-H increased constantly and grew intertwined with each other, which lead to the denser microstructure of stabilized soil and better mechanical strength.

“…For example, certain plant-based waste materials may contain a wealth of hydrophobic compounds [42,43]. The augmentation of surface micro and nanostructures on waste materials serves to heighten their hydrophobic characteristics by increasing surface roughness [40,51]. This emulates the naturally occurring superhydrophobic surfaces observed in flora and fauna.…”

Superhydrophobic materials, known for their exceptional water-repellent properties, have found widespread applications in diverse fields such as self-cleaning surfaces, anti-icing coatings, and water-resistant textiles. In recent years, researchers have explored a sustainable approach by repurposing waste materials to create superhydrophobic surfaces. This eco-friendly approach not only reduces environmental impact but also aligns with circular economy principles, contributing to a more sustainable future. Creating superhydrophobic materials from waste involves a combination of surface modification techniques and hierarchical structuring, with rigorous characterization to ensure the desired properties. These materials showcase their potential in various industries, opening doors to more environmentally friendly technologies. This review delves into the concept of superhydrophobic materials derived from waste and the methods used for their synthesis. It begins by defining superhydrophobicity and highlighting its unique characteristics. It emphasizes the pivotal role played by superhydrophobic materials across industries. The review then explores waste materials’ untapped potential, discussing the advantages of harnessing waste for superhydrophobic material development. Concrete examples of promising waste materials are provided, including agricultural residues and industrial byproducts. The review outlines five key sections that will be further developed to offer a comprehensive understanding of this innovative and sustainable approach to superhydrophobic materials.
