Thermoplastics are polymers that can be repeatedly softened by heating and hardened by cooling. Polyethylene (PE) is a common thermoplastic known for its flexibility and low cost.

Recycling polymers serves multiple purposes, including reducing the amount of plastic waste sent to landfills, conserving non-renewable resources used to produce virgin polymers, and lowering greenhouse gas emissions associated with polymer production.

Polyethylene Terephthalate (PET) is widely used in food packaging due to its clarity, strength, and ability to maintain product freshness.

Mechanical recycling involves physically breaking down and reprocessing废塑料to create new plastic products.

Recycling polymers faces several challenges, including contamination of plastic waste, high energy consumption during recycling processes, and limited availability of recycling facilities in some regions.

Chemical recycling involves breaking down废塑料into smaller molecules through chemical processes, allowing them to be converted into fuels or other valuable chemicals.

Polypropylene (PP) is frequently used in automotive parts due to its strength, durability, and resistance to chemicals and heat.

Tertiary recycling refers to the process of using recycled polymers in new products, either directly or after further processing.

Polylactic Acid (PLA) is a biodegradable polymer derived from renewable resources like corn starch or sugarcane.

Sustainable polymer recycling aims to minimize environmental impact, reduce production costs, and improve product quality by using recycled polymers as a valuable resource.

Polycarbonate (PC) is often used in medical devices due to its clarity, strength, and biocompatibility.

Mechanical separation involves using physical methods such as size, shape, or density differences to separate different types of polymers from a mixed plastic waste stream.

Using recycled polymers in new products can lead to reduced energy consumption, lower greenhouse gas emissions, and improved product performance due to the reduced need for virgin materials.

Feedstock recycling involves converting废塑料into a feedstock, such as pyrolysis oil or syngas, which can be used to produce new polymers.

Acrylonitrile Butadiene Styrene (ABS) is frequently used in electronic devices due to its strength, toughness, and resistance to heat and chemicals.
