Arizona Alternative Materials is one of the largest processors of PC4 in the United States. When recycling post-consumer carpet, it typically undergoes a deconstruction process to separate the valuable face fiber from the other components. Polypropylene is used for primary and secondary backing for carpet and calcium carbonate for weight. Regardless of how efficient the carpet recycling process is, it is virtually impossible to completely separate components that come together to make carpet. Once the face fiber and polypropylene have been separated and recovered, the residual material is classified at PC4. It is made up of mostly calcium carbonate but also residual face fiber, polypropylene, latex and adhesive.
