Imagine spending days washing and processing tons of plastic bottles, only to have the buyer reject the entire batch. This is a common nightmare for recycling plant owners, and the most frequent culprit is hidden in plain sight: transparent polyvinyl chloride<\/a> (PVC).<\/p>\n\n\n\n

Visually, a clear PVC bottle looks exactly like a clear PET water bottle. However, allowing them to mix is like mixing salt into a sugar jar. Failing to control PVC contamination in PET recycling won’t break your washing machines<\/a>, but it will completely ruin the plastic material itself. To understand why we must avoid PVC at all costs, we need to look at what happens when your buyer tries to use the plastic flakes you sell them.<\/p>\n\n\n\n

Most recycling lines use sink-float separation tanks<\/a><\/strong> to clean the material. These water tanks work on a simple rule: light things float, heavy things sink. Plastic bottle caps are light, so they float to the top and get skimmed away. The trap here is that PVC and PET weigh exactly the same in water. Because both materials are heavy, they both sink straight to the bottom. Water cannot separate them.<\/p>\n\n\n\n
