The Environmental Impact of ZipLoc Bags

Week 36

Plastic storage bags, often referred to by well known brand name, ZipLoc, are a staple in in nearly every household. In fact, most estimates show that the average American family uses 500 ZipLoc bags every year. Though commonly found in the kitchen, they are equally useful around the home and on the go. Unfortunately, their convenience comes at a price. So, this week, we are swapping these disposable baggies for something that won't inevitably end up in our landfills or waterways.

Why are ZipLoc bags a problem?

Plastic storage bags are made of either low-density polyethylene (or LDPE) or high-density polyethylene (or HDPE) that fall under the category of plastic film. According to the EPA, 4.2 million tons of plastic bags and films were generated in 2018 and 3.04 millions tons ended up in a landfill. Like all plastics, they are made from crude oil, a non-renewable resource, which is problematic for two reasons: manufacturing generates significant pollution and the product is not biodegradable. As put it, "they are difficult to produce and nearly impossible to get rid of once produced".

Most plastic bags take a minimum of 400 hundred years to break down. If that fact doesn't get your blood boiling, think of it this way...every plastic bag that's ever been sent to a landfill still exists. It gets worse. According to, plastic bags cause over 100,000 sea turtle and other marine animal deaths every year when animals mistake them for food.

Are plastic storage bags recyclable?

Technically, most plastic zipper storage bags are recyclable. However, since they are considered a plastic film, they should never go into your curbside recycling, as they can clog the machinery at recycling facilities. Many grocery stores offer plastic film recycling drop offs near the front doors, but the bags should be clean and contain no food remnants. If yours doesn't, use this link to search for a drop off location in your area. Or, consider sending them to Terracycle for recycling.

What can I use instead?
