Previously, this brigade only accepted stackable yogurt cups. I'm happy to announce through the upcoming Dairy Tub Brigade, we can now collect any kind, including non-stackables (like Yoplait, 4- and 6-packs, etc.). This information is not yet updated on the Yogurt Brigade page, so don't be misled that it only says stackable there. What can be TerraCycled in this category? Answer: any brand, size, and shape of yogurt container What does this waste get used for? Our yogurt cups are made into recycled plastic products that can themselves be recycled into more useful items!
