PVC pipe: Polyvinyl chloride (PVC) pipe, by far the most commonly used pipe in residential homes, is the white pipe commonly used in plumbing applications. Easy and versatile with a variety of fittings and sizes, PVC is ideal for most applications in hot and cold water. PVC functions well for home plumbing piping because over time it does not rust or corrode. It is also easy to work with, because it does not require welding or metal-working and is a cheap option for your home. The main disadvantage of the PVC pipe is that it cannot be used for hot water. PVC will warp when exposed to hot water.

New techniques are being developed to recycle polyvinyl chloride plastic waste to reduce the consumption of the biomass used to produce PVC products. The recycling process breaks PVC down into synthetic gas and hydrogen chloride (HCl), which are then available for use in the production of new PVC products.
Air pollution control and mitigation

Dioxins are mainly formed when chlorine or a material containing chlorine is heated at high temperatures. They are mostly released to the environment via the uncontrolled incineration of hospital waste and municipal solid waste containing certain plastics such as polyvinyl chloride (PVC). Dioxins are found throughout the world even though formation of dioxins is local.
Numerical study of behavior of textile-reinforced composite tubes under lateral compression
Published in Mechanics Based Design of Structures and Machines, 2023
Tube forms are frequently known for their energy-absorbing properties. They can deform plastically and can behave in the flexible manner according to the material properties. Thus, cylindrical tubes or cylindrical-formed structural units have numerous applications in automobile industry, aerospace, and offshore structures. The tube-shaped TRCCs examined in this research may be an alternative to the drainage pipe. In general, PVC (polyvinyl chloride) is one of the most common materials in drainage system. However, PVC pipes have some disadvantageous due to their non-decomposing properties, and the chlorine compounds that are released into environment. In addition, the strength of plastic pipes decreases at high-temperature areas, and they can be easily cracked owing to their thinner wall. On the other hand, traditional cast iron sewer pipes are not resistant to corrosion, so they require coating. At this point, TRCC tubes have some advantages over conventional drainage pipes. Thus, this study also demonstrates the advantageous of TRCC tubes.

Polyvinyl chloride (PVC) is the world's most widely produced synthetic plastic polymer, second to the polyethylene (Akovali 2012), having properties such as stiffness, lightness, impermeability, chemical, and biological inertness, durability, and low natural flammability. PVC is mainly used for the production of pipes, bottles, non-food packaging, cards, plumbing, toys, bedding, cable coatings, furnishings, phonograph records, and building and construction industries comprising about 65% of PVC (Kaley et al. 2006). About 4% of PVC additive to asphalt caused an increase in kinematic viscosity, stability, stiffness, indirect tensile strength, and reducing penetration, and lower flow than virgin mixtures (Wong and Li 2009). Waste plastics, (waste polyethylene (WPE) & Waste polyvinyl chloride (WPVC)), are being disposed of in the open space causing a significant threat to the global environment, health, agricultural production, and drainage system because this is readily non-biodegradable material and accumulating. It could be a source of modifier agent of asphalt cement as well as the reduction of environmental pollution.

There have been several studies on reusing recycled plastic with other construction materials for different structures. Hama and Hilal (2019) investigated fresh properties of concrete containing plastic aggregate and reported that workability of such concrete increases with the use of recycled plastic. Also, they have reported that the density of plastic-filled aggregate concrete is lower compared to the concrete without plastic. To further ascertain the potential risks of using shredded tyre, a series of chemical and leachate tests were conducted on shredded tyre samples, which are described in the following section. Polyvinyl chloride (PVC) products are significant portion of plastic wastes dumped in our environment. Mohammed (2019) investigated uses of different forms (aggregate, powder, and chopped insulating wire) of PVC in concrete and reported that presence of PVC in the concrete reduces the workability as to maintain the workability use of superplasticizer is needed. Also, it is found that replacing normal aggregate with PVC aggregate considerably reduces the concrete density and compressive strength. Khatib, Herki, and Elkordi (2019) investigated the use of expanded polystyrene, EPS, (which is mainly used as a packaging/insulating material) in lightweight concrete replacing natural aggregate. They have reported that EPS can be used as lightweight aggregate; however, due to its very light weight can cause segregation during mixing with concrete. As such addition of bonding agent, heat treatment, and/or coating is required as treatment to prevent segregation. Due to its light weight, which makes it unsuitable for heavy load-bearing concrete, Mohammadinia et al. (2019) investigated mixture of recycled plastic waste (RPW) and recycled glass (RG) as aggregate in the concrete for footpath construction. They have found that compressive and splitting tensile strength values of such concrete containing RPW and RG aggregate are reduced due to low adhesion between the recycled aggregates and the cement gel matrix. However, replacement of up to 20% (by volume) for RPW and up to 30% (by volume) for RG is still viable for footpath construction.
