This is especially the case for hot food which can cause chemicals to leach from the plastic container into the food. You can buy canning jars and re-usable screw-on lids, or even better, wash out jam, peanut butter, or spaghetti sauce jars and use them for storing leftovers. They are also great for storing food items that you buy in the bulk section, like dry pasta, dried beans, and rice. Another advantage to glass for storage is that you can see the contents so that you can remember what leftovers need to be eaten (link to other tip). When your glass jars are no longer useful, recycle them at the Swarthmore Recycling Center.
