Instead of throwing away perfectly good Ziploc bags, save them for future use. As long as the bag is clean and dry, you can use it multiple times. I especially make sure to save the gallon size bags since they seem to last longer than smaller ones. This go green tip is simple but effective. I also re-use aluminum foil when possible. There's just no need to throw these type of items away when you can use them again. You'll save money and will help do your part to keep less trash out of the landfills.
