How recyclable is a yogurt cup? A report recently stated that polypropylene (PP) the material for which yogurt cups are made, was not recyclable. The reason for this statement was strictly based on the difficulty of separating PP from the similarly ubiquitous material, polyethylene. Polypropylene and polyethylene are not miscible materials, meaning that when blended, the subsequent blended product is not usable due to the two-phase nature of the blend. (9) Processors that use recycled material would prefer not to deal with the contamination and thus discourage the introduction of PP to their material stream. Simply stating that polypropylene is not recyclable is not true. Anyone familiar with polymer processing knows that you can simply reduce the particle size of the yogurt cup, feed it back into the melt process of your choice, and remake the yogurt cup. But that does come at some cost, but at what cost? How many times can that cup be reprocessed, and it still preform as intended? This study seeks to shed some light on that question.
