What is plastic-shredding machinery used for?

• A. Machinery that breaks plastic waste into smaller pieces for easier processing.
• B. To melt plastic into liquid form.
• C. To compress plastic into pellets.
• D. To separate plastics by type.

Answer: (A)

Plastic-shredding machinery is designed to physically break plastic waste into smaller pieces. This size reduction starts the recycling process by producing uniform fragments that are easier to handle, wash, sort, and feed into downstream equipment like extruders or mixers. Smaller pieces also improve processing efficiency, reduce energy use, and help transport and storage. Other tasks—melting plastic into a liquid, compressing it into pellets, or sorting by type—are carried out by different machines specialized for those functions, not shredders.
