Coffee Bags Special Instructions Coffee bags can be placed in the compost cart or the landfill cart – depending upon what it is made out of. If your coffee bag is made out of plastic, it must be placed into the black landfill cart. If your coffee bag is made out of paper, then it can be put into your brown compost cart. Ways to Reduce Buy Coffee in Bulk Instead of buying single bags of coffee, buy coffee beans from the bulk section of your supermarket. Bring an empty coffee bag or jar into the store for your coffee instead of using a brand new container every time. Ways to Reuse Upcycle Your Coffee Bag You can turn a plastic coffee bag into a planter or vase, or you can turn several into a reusable tote bag.
