One common application of positive displacement blowers is in the recycling industry. Used plastic packaging–from large industrial manufacturers all the way to households that toss their plastic waste into curbside bins–is taken, sorted, and processed down into small pellets or flakes that can then be reused for new goods. These three pressure packages will be used to convey two different types of plastic pellets: HDPE (high-density polyethylene) and PP (polypropylene).
