What is plastic-shredding machinery?

• A. Extinguishing systems for plastic fires.
• B. Devices for inspecting plastic quality.
• C. Equipment for molding plastic into bottles.
• D. Machinery that breaks plastic waste into smaller pieces for easier processing.

Answer: (D)

Plastic-shredding machinery is equipment designed to reduce plastic waste into small pieces. It uses blades or cutters to tear or grind plastic into uniform chips or flakes, which is essential because smaller pieces have more surface area for cleaning, sorting, and melting. This size reduction makes recycling more efficient and economical, since the shredded plastic can be washed, separated, and melted or pelletized more easily and with less transport volume.

Extinguishing systems for plastic fires are for safety and suppress flames, not processing material. Devices for inspecting plastic quality are measurement tools used in quality control, not breaking down waste. Equipment for molding plastic into bottles refers to forming processes that create products, not dismantle waste.
