Try as we might, not all of our plastic food containers are recyclable. But instead of tossing the plastic you can’t recycle, considering using it again in replace of those eco-unfriendly Tupperware containers. One quick rinse (remember that it’s best to hand-wash plastics as opposed to running them through a dishwasher, which uses extremely hot water that can result in unwanted exposure to Bisphenol A) and your old containers are good as new. Worried about confusing one food product for another? Use a strip of paper tape to cover old labels and record contents and date.
