Polypropylene is a recyclable plastic. However, less than 1 percent of polypropylene-made post-consumer products are recycled in the United States every year, according to About.com as of 2014.
Found in products such as yogurt containers, maple syrup bottles and straws, polypropylene has a decomposition time of two to three decades. The recycling process for polypropylene involves cleaning the waste then melting the plastic into products such as manhole covers and plastic lumber. The intensive recycling process, which includes heating the product to high temperatures and creating harmful gas byproducts, creates challenges for encouraging consumers to recycle their polypropylene waste products.
The plastic is also known as resin code number 5 or PP.
