Plastic is a surprisingly versatile material with elemental origins. Elements from the periodic table, such as carbon, hydrogen, oxygen, nitrogen and sulfur, are the building blocks for a variety of plastics used to make many of the products we
Polyvinyl Chloride (PVC) Plastic: Uses, Properties, Benefits & Toxicity
Basic Forms of PVC Polyvinyl Chloride is widely available in two broad categories: Flexible and Rigid. But, there are more types like CPVC, PVC-O and PVC-M. Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm 3): Flexible PVC is formed by the
Polyvinyl Chloride (PVC): PVC is a thermoplastic that is formed when vinyl chloride (CH2=CH-Cl) polymerizes. When made, it's brittle, so manufacturers add a plasticizer liquid to make it soft and moldable. PVC is commonly used for pipes and

- What enzymes are used in wastewater treatment?
- There are six kinds of enzymes and the most used ones in wastewater treatment are hydrolases and oxidoreductases (Mishra et al., 2025, Varga et al., 2019). These two enzymes can biocatalyst most pollutants in wastewater due to their wide range of substances. At present, enzymes like lipase, laccase, peroxidase have been commercially used.
- Are enzyme-related wastewater treatment systems eco-friendly?
- In enzyme-related wastewater treatment systems, free enzyme systems can achieve good treatment performance under certain circumstances, but these systems may not cost-effective and/or eco-friendly. It is necessary to find high-efficiency and commercial enzymes to reduce the cost.
- Why are immobilized enzymes used in wastewater treatment?
- Immobilized enzymes are used extensively in waste water treatment because they are less expensive, more ecofriendly, and simpler to use. In this chapter, applicability of immobilized enzyme systems for the treatment of various chemical compounds present in wastewater has been discussed.
- Are enzymatic bioprocesses a priority in wastewater treatment?
- Enzymatic bioprocesses demonstrate their priority in wastewater treatment. Enzymes show promise in resisting pollutants removed from wastewater. Identification and ecotoxicity assay of enzymatic byproducts are important. Enzyme mediators improve enzymatic processes but there are drawbacks.
