Plastic grocery/retail bags have many post first-time uses ("Bag it, City Council," Nov 11). We use many of them along with an inner paper bag as liners for our house garbage cans. They are efficient and easy to handle. Once thrown into the garbage, they are hauled away to the Baltimore waste-to-energy plant to be converted to electricity. The energy content of these bags, by the way, is equivalent to that of oil. Said bags are also used as packing cushioning or bags for other household items where spillage might be an issue.
