HDPE
HDPE (High-Density Polyethylene) is one of the most common types of plastic used in everyday products and packaging. It's highly valued in the recycling industry because it can be easily recycled and turned into new products. Think of it as the plastic used in milk jugs, detergent bottles, and shopping bags. In recycling job descriptions, you'll often see HDPE mentioned alongside other plastic types like PET or PP. When someone lists HDPE experience on their resume, they're typically indicating they have worked with sorting, processing, or managing this specific type of plastic material in recycling operations.
