We don’t recommend the recycling of the Black Berkey® Purification Elements, PF-2s or PF-4s. The shells of the Berkey® PF-2™ and PF-4™ are made of Polypropylene, which is Recycle Code 5. Uses of Polypro (for short) include catsup bottles, yogurt containers, margarine tubs & medicine bottles. However, there is no recycle code for the Berkey PF™ elements. As we understand it, a recycle code cannot be assigned since the element is sealed and contains material inside for arsenic & fluoride reduction. To recycle, one would have to cut the element open and remove the material before recycling the plastic shell.
The same issue applies to the Black Berkey® Purification Elements. The complex matrix of materials involved in the manufacture of the BB9 elements does not allow the elements to be easily classified by a single recycle code. In addition, with both of these types of elements, there is no way of knowing what contaminants are in the media after use.
