The first step is the collection and sorting of plastic waste. This is crucial because not all types of plastic can be recycled. Proper sorting increases the efficiency of the recycling process and enhances the quality of the resulting plastic resin.

Plastic waste is typically collected from recycling centers, supermarkets, and residential areas. Once collected, plastics are sorted by resin identification codes (usually labeled from 1 to 7) to facilitate proper processing.

2. Cleaning and Processing Waste

After sorting, the plastics must be thoroughly cleaned and processed. This involves removing impurities, dirt, and other contaminants. Cleaning is a critical step — if not done properly, leftover impurities can compromise the quality of the recycled plastic.

This cleaning process may involve hot water, chemical solutions, or even ultrasonic waves to ensure all contaminants are completely removed.

3. Shredding and Recycling

Once cleaned, the plastic waste is shredded into smaller pieces. Shredding increases the surface area, making the recycling process more efficient.

The shredded plastic is then fed into a recycling machine, where it is melted down and reformed into recycled plastic pellets. Temperature control during this stage is essential to preserve the chemical properties of the plastic and ensure product consistency.

Additives and Final Product Finishing

Finally, once the plastic pellets have been formed, additives are often introduced to enhance their properties. These additives can improve durability, UV resistance, or the flexibility of the resin.

After additives are incorporated, the recycled plastic pellets are packaged and distributed to the market. These finished products can then be used across various industries, from packaging to construction.
