The recycling process for plastic bottles has evolved with technology, making it more efficient and eco-friendly. Modern recycling methods involve grinding the bottles into flakes, which are then thoroughly washed. Here’s where the cap comes into play. Caps are usually made of a different type of plastic than the bottle itself, and they have a tendency to float during the washing process, while the bottle flakes sink. Separating them is like a sorting puzzle, and it requires extra time, energy, and resources. By keeping the cap on, you’re helping recycling facilities streamline their operations. It’s a small change that can make a big difference in the efficiency of the recycling process. And it’s not just about convenience—it’s about sustainability.
