As we all know, plastic is a waste that has threatened human health and the environment. Currently, many countries have pushed out the “plastic ban” in the world. But, there is still a huge amount of plastic production every year. A statistic shows that the worldwide production of plastics reached a staggering 390.7 million metric tons in 2021. Plastic recycling is a problem that needs to attract people’s attention.
The raw materials used to make plastic are derived primarily from petrochemicals. Here, we will list the ingredients for making traditional petrochemical-based plastics:
Acrylic is a general term that refers to a group of synthetic resins or plastics derived from acrylic acid. PMMA is a specific type of acrylic. Acrylic is a transparent thermoplastic used as a lightweight, shatter-resistant alternative to glass. Also, it has applications in products like optical lenses, signage, aquariums, and various household items.
Because of tough, stable, and transparent, Polycarbonate is an excellent plastic. Its clearness is the same as glass and its strength is two hundred and fifty times stronger than glass. Polycarbonate plastic sheets can be cut or cold-formed on-site without pre-forming and fabrication. Polycarbonate plastic is in a wide variety of products including greenhouses, DVDs, sunglasses, police riot gear, and more.
Polyethylene is the most common plastic that has varying densities. Different densities of polyethylene are suitable for making different final plastic products. Here, we list them for your reference:
Polypropylene (PP) is a thermoplastic polymer that is widely used in various applications due to its versatile properties. It has many features: lightweight, high melting point, resistance to moisture, high tensile strength, flexibility, chemical resistance, transparent or translucent, and recyclability. Here, we list the common usages of PP for you.
Polyethylene Terephthalate (PET) is also a type of thermoplastic polymer. Here, we list some characteristics and applications for your reference:
Polyvinyl Chloride, commonly known as PVC, is a versatile and widely used thermoplastic polymer. It has high density, high durability, transparent or opaque, rigid or flexible, good tensile strength, dimensional stability, impact resistance, chemical resistance, flame resistance, electrical insulation, and so on. Here are the key and uses of PVC:
Acrylonitrile Butadiene Styrene, commonly known as ABS, is a thermoplastic polymer with a combination of properties that make it suitable for various applications. It has features of rigid and tough thermoplastic, glossy appearance, good tensile, resistance to abrasion, moderate heat resistance, chemical resistance, and ease of processing. Here are the applications of it:
Plastics can pose various environmental and health hazards throughout their life cycle, from production to disposal. Some of the key hazards associated with plastics include:
Chemical Additives: Some plastics contain additives, such as plasticizers, flame retardants, and stabilizers, which can leach into the environment. These additives may be harmful to human health and the environment.
Production and Incineration: The production of plastics, particularly from fossil fuels, contributes to greenhouse gas emissions. Incineration of plastics can release toxic pollutants into the air.
Fossil Fuel Dependency: The production of many plastics relies on fossil fuels, contributing to resource depletion and dependence on non-renewable resources.
Ingestion and Entanglement: Wildlife, especially marine animals, may ingest or become entangled in plastic debris, leading to injury or death.
Litter and Aesthetics: Improperly disposed plastics contribute to litter, affecting the visual appeal of natural landscapes and urban areas.
Efforts are being made globally to address these hazards, including initiatives to reduce single-use plastics, improve recycling systems, and develop alternative materials. Individuals and communities can also contribute by practicing responsible plastic use, recycling, and supporting policies that promote sustainable plastic management.
Pyrolysis is the chemical decomposition. Plastic pyrolysis technology is a thermal degradation process in the absence of oxygen. With the temperature rising, plastic waste begins to decompose into smaller molecules. And, finally, you will get pyrolysis oil from plastic. Here, I will share the detailed processes for you:
Not all kinds of plastic can be pyrolyzed to oil. Here, we list acceptable plastics and oil yields for you. You can compare the data to choose your plastic pyrolysis recycling solution.
