All items that TerraCycle accepts to upcycle into new products will now be collected at five Walmart stores on the East Coast, the first retail outlets to test the new collection system, according to Green Biz. All told, the new collection system will accept 28 types of trash that can’t be recycled and would otherwise go to landfills, which TerraCycle turns into new products such as tote bags, plant pots, backpacks, pencil cases and portable speakers.
