PET (Polyethylene Terephthalate): Commonly used in water and soda bottles.

Highly recyclable and often used to make polyester fibers for clothing and carpets.

HDPE (High-Density Polyethylene): Found in milk jugs, detergent bottles, and some plastic bags. 

Easily recycled and used for new bottles, pipes, and plastic lumber.

PVC (Polyvinyl Chloride): Used in pipes, cable insulation, and some packaging.

Recycling is possible but challenging due to the release of harmful chlorine gas. It is less commonly recycled.

LDPE (Low-Density Polyethylene): Used in plastic bags, six-pack rings, and some containers.

Easily recycled into new plastic bags and plastic lumber.

PP (Polypropylene): Found in yogurt cups, bottle caps, and some packaging.

Easily recycled into containers, pallets, and automotive parts.

PS (Polystyrene): Used in foam packaging, disposable cups, and food service trays.

Recycled less frequently due to its lightweight nature and potential contamination issues.

Biodegradable Plastics: Some companies are developing biodegradable plastics that break down more easily in the environment. However, challenges exist in terms of scalability and ensuring they don’t contaminate traditional plastic recycling streams.

Microplastics: Microplastics are tiny plastic particles, often less than 5mm in size, which can result from the breakdown of larger plastic items. Proper recycling can mitigate the generation of microplastics, as it reduces the amount of plastic waste that enters the environment.

Water Treatment Challenges- Microplastics can be challenging to filter out in water treatment plants, potentially impacting water quality.

Nylon and Other Specialty Plastics: Some plastics, like certain types of nylon, face challenges in recycling due to their complex chemical structures.

Composite Materials: Products made from a combination of materials (e.g., packaging with mixed materials) can be difficult to recycle.

  • Recycling Process

Collection: Consumers separate plastic waste from other recyclables at home or through designated collection programs.

Sorting: At recycling facilities, plastics are sorted based on their resin identification code (the number inside the recycling symbol).

Cleaning: Plastics are washed to remove any impurities, labels, or contaminants.

Shredding: The cleaned plastic is shredded into small pieces, increasing its surface area for processing.

Melting/Reforming: The shredded plastic is melted and then formed into pellets or other shapes for reuse.

Manufacturing: These pellets are used in the manufacturing of new plastic products.

Recent Developments in the field of Recycling of Plastic

  • Technological Advances

Ongoing researches aim to improve the efficiency of plastic recycling processes.

Innovative technologies, show promise in breaking down plastics into their original components for higher-quality recycling.

Top Plastic Recycling Trends

  • Pyrolysis

Thermal degradation of hydrocarbon plastic waste in the absence of oxygen generates Pyrolysis. Advances in pyrolysis technology, such as fast and ultra-fast pyrolysis, allow plastic waste recyclers to recycle massive amounts of waste flows within shorter periods.

  • Innovative Depolymerization

Breaking down plastic waste into its monomer allows recyclers to recover a great fraction of materials from the waste source. This is due to the shorter recycling loop in depolymerization techniques.

  • Advanced Mechanical Recycling

Mechanical recycling is the most profitable means to manage waste plastics. The efficiency of mechanical recycling processes significantly impacts the innovations in waste collection, sorting, and separation. This includes AI-assisted systems to speed up plastic waste classification at processing sites.

  • Automated Recycling

AI-enabled solutions in the plastic recycling industry automate processing lines and improve waste separation. This enables plastic recyclers to tackle worker scarcity while enhancing operational efficiency. As a result, it reduces the workers’ exposure to high heat and increases their safety.

  • Recyclates

Most of the plastic waste ends up in landfills and incinerators because they are not designed for recycling at their end of life. That is why various startups are developing materials optimized for recycling. These include mono-material plastics that increase recycling efficiency and recyclable, low-carbon plastic alternatives. 

  • Advanced Gasification

Gasification systems thermally treat plastic waste under oxygen starvation. Moreover, this technology supports a mixed waste stream that is otherwise non-recyclable. 

  • Plastic Traceability

Around 91 percent of plastic products are lost due to a lack of visibility into their lifecycle. To tackle this, startups develop plastic traceability solutions that allow recyclers to track back their flow. 

  • Solvent-based Purification

Dyes and additives in plastic waste limit material recovery in mechanical recycling facilities. Selective solvent dissolution or solvolysis, on the other hand, removes impurities from post-industrial and post-consumer plastic waste. This results in the recovery of very high-quality plastics. 

 

Challenges in Plastic Recycling
