How plastic is recycled ? / How recycled plastic granules are made ?

1. Collection and Sorting:

• Plastic waste is collected from homes, businesses, and recycling centers.

• These materials are then sent to a Material Recovery Facility (MRF) or Plastic Recovery Facility (PRF) for sorting.

• Sorting can be done manually or with automated equipment like optical sorters that identify different types of plastics.

• Manual picking is used to remove large items and sort out any non-plastic materials.

• Optical sorting machines use infrared measurements to identify plastic types.

2. Cleaning and Shredding:

• Once sorted, the plastic waste is washed to remove any dirt, food residue, or other contaminants.

• The cleaned plastic is then shredded into smaller pieces or flakes.

3. Melting and Pelletizing:

• The shredded plastic is melted down in an extruder, and the melt is pressed through a filter to purify it.

• The liquefied plastic is then cooled and processed into small pellets, also known as "nurdles".

4. Manufacturing New Products:

• These recycled plastic pellets are then sold to manufacturers who use them to create new products.

• These products can include things like clothing, containers, bins, and even infrastructure components.
