Plastic recycling, HDPE, LDPE, and PET are key types of plastics with distinct uses and recycling potentials. HDPE, known for its strength, is used in bottles and pipes, and is easily recyclable. LDPE, found in plastic bags and films, is more flexible but challenging to recycle due to contamination. PET, widely used in beverage bottles and packaging, is highly recyclable and often repurposed into new products. Effective recycling of these plastics plays a crucial role in reducing plastic waste and promoting sustainability.
