Ziploc bags can be recycled just like other plastic bags can.
Some stores have places where you can drop off old Ziploc bags that are clean and ready for being recycled.
However you should reuse the Ziploc bag as many times as you can before it wears out.
You can wash and reuse Ziploc bags more than a few times and use them over and over until they wear out instead of just throwing them out after one use.
Simply turn them inside out and wash them with soapy water and allow them to dry before reusing them.
You can even put them on the top rack of your dishwasher and clean them that way.
Ziploc-brand bags and other sandwich bags can be recycled with other types of film plastic, including shopping bags, dry-cleaning bags and produce bags.
The best place to find recycling centers for these products is your local grocery store.
Many retailers offer bins right inside the door that collect film.
