Brita® pitcher filters are accepted at many Whole Foods locations for recycling, including the ones in Hingham and Weymouth.
Some of these programs have been curtailed or moved to Customer Service. A fresh list of locations will be available sometime in 2019.
Preserve (aka Recycline), based in Massachusetts, transforms these, as well as Stonyfield Yogurt containers and other clean #5 (polypropylene) plastics into toothbrushes, plates, cutting boards, etc.
