“How can different types of polymers be identified, classified, and sorted based on their physical and chemical properties, in order to improve recycling processes and reduce environmental impact?”

Factors Considered
-
Properties
Texture
The Texture of the Plastic can vary depending on the Slipperyness, Smoothness or Waxness. For Example, Low Density Polyethelyene bags are usually smooth and silky.
Malleability
Can the Plastic Resist the Malformation or can the plastic bend. For example, Low Density Polyetheylene isn't bendable due to its rigid structure.
Thermal Behaviour
Thermoplastics usually soften and melting up while Thermosets reduces or chars. For example, Polyetheylene is a Thermoplastic and when set up in flames, the plastic would melt and soften due to its low melting points
Density
Plastics such as High Density Polyethelyne can float while Polyethelyne terephlate can sink due to its low density.
Appearance
Assessment that can check which type of polymer. For example, usually, High Density Polyethelyne are usually non translucent. This means that the High Density Polyethelyne cannot let light to pass through without absorbing it.
