Good news on the recycling market front! The polypropylene plastics (PP) market is strong here in the U.S., thanks to plastic recyclers like KW Plastics in Troy, Alabama. Most Massachusetts MRFs are sorting, baling and selling PP containers domestically (as opposed to exporting it.) KW Plastics converts it into a valuable manufacturing feedstock for new products. In 2018 they purchased 3.2 million pounds of polypropylene containers from Massachusetts MRFs.
What is polypropylene? It’s a versatile plastic that is used to make a variety of containers in many shapes and sizes. These include tubs and lids (think yogurt, margarine, sour cream, etc.), bottle caps and closures, take-out containers and plastic storage totes. Unlike some plastic resins, polypropylene can be injection-molded and blow-molded and still recycled afterwards since heating it doesn’t irreversibly change its chemical properties. The tubs and lids that you put in your recycling bins are made into plastic paint cans, razor handles, toothbrush handles, cosmetic tubs, and toys and more.
According to a recent report released by the Association of Plastic Recyclers – making products from recycled (instead of virgin) PP reduces greenhouse gas emissions by 71%! The take-away? Encourage your community to recycle their plastic bottles, jars, jugs & tubs – with the caps and lids attached – and forget about the numbers on the bottom. Not everything with a number is recyclable. By focusing on certain plastic resin numbers we end up with a lot of non-recyclable materials and may not capture items that are recyclable like tubs and lids!
