Tupperware is easy to use, easy to wash, and fairly easy to store. But enough use can wear down your Tupperware like anything else. So, what do you do with your Tupperware when it no longer serves it’s purpose – is Tupperware recyclable?

In this article we cover exactly what you can do with your old Tupperware, when to throw away Tupperware, whether it is recyclable or not, Tupperware alternatives, and more.

Does Tupperware expire?

The majority of Tupperware will expire. Although, the lifespan of your Tupperware will vary based upon frequency of use and type of use. Foods that are high in acidity, such as garlic or tomatoes, can penetrate the Tupperware easier and weaken it.

The average homeowner can expect to get around 10 years of use out of their Tupperware before having to give it a new home. It’s more than possible to get 20 years of use out of your Tupperware containers, but given enough time all products will lose their shape and function.

There are several signs that it could be time to replace your plastic Tupperware containers:

  • Hard Stains: The years’ worth of food that was stored in your Tupperware will undoubtedly leave a mark – even if you always washed it diligently. If you aren’t able to scrub out harsh stains from your Tupperware, it’s a sign that food residue has seeped into the pores of the Tupperware material.
  • Off/Odd Smell: Weird smells in old Tupperware often come from the food residues of the hard stains. These stains and smells aren’t exactly pleasant – it’s almost like your Tupperware is telling you to get rid of it!
  • Warping: If your Tupperware has warped to the point where it’s become difficult to fit the lid on, it’s probably time to replace it. Years of use and microwave heat will eventually make almost all Tupperware warp to some degree or another.
  • Cracking: Normal wear and tear alongside aging can sometimes cause Tupperware containers to crack. Cracks not only break the airtight seal your container had, but also may lead to leaking and a messy refrigerator.

Is Tupperware BPA free?

BPA, Bisphenol A, is present in some plastic Tupperware containers. Bisphenol A is a chemical used in the production of many plastics and epoxy resins. There has been research since the 1960s showing that BPA may contribute to the onset of certain diseases such as diabetes, multiple cardiovascular diseases, and cancer. It’s also been linked to infertility and hormone disruption. [2]https://universityhealthnews.com/daily/nutrition/is-tupperware-bpa-free/

If your Tupperware was manufactured before 2010, it almost certainly contains BPA, as almost all major brands used the chemical to make polycarbonate plastic up until that date. Most Tupperware containers manufactured today are BPA free. You can be certain your container doesn’t contain BPA if it’s marked by a number 1,2, or 5.

Is Tupperware recyclable? – old Tupperware warning

Some plastic Tupperware containers are recyclable. Whether your Tupperware is recyclable or not will be dictated by a few numbers and symbols on the bottom of the container. You’ll know for certain that you can recycle your container if there is a recycling symbol on it – a triangle made up of three arrows – accompanied by a number 1,2 or 4.

On the other side of things, if your Tupperware container is marked by a 5 or 7, it’s unlikely you’ll be able to recycle it. Number 5 and 7 plastics are not generally accepted at recycling centers, so be sure to check your containers before recycling them. If you can, reach out to your local recycling facility to find out what number plastics they accept beforehand.

The numbers located on the bottom of your plastic containers each denote a certain material:

  1. PETE (Polyethylene Terephthalate): used in some Tupperware containers. Is recyclable.
  2. HDPE (High-Density Polyethylene): used in some Tupperware containers, plastic wraps, and plastic bottles. Is recyclable. 
  3. PVC (Polyvinyl Chloride): used in a variety of plastic products, not Tupperware.
  4. LDPE (LowDensity Polyethylene): used in some Tupperware, sandwich bags, and grocery bags. Usually non-recyclable.
  5. PP (Polypropylene): used in many Tupperware containers and other hard plastic containers. Select recyclability.
  6. PS (Polystyrene): used in Styrofoam and other disposable packaging materials. Can’t be recycled.
  7. All other plastics: May be in any product. Almost never recyclable.

Is old Tupperware dangerous?

There are a number of different factors that may make your Tupperware unsafe to store food in or eat out of. As we went over, if BPA is present in your Tupperware, it can be dangerous to use because BPA has been linked to the onset of several diseases and health complications.

Old Tupperware can sometimes just be dangerous in the sense that it’s “old.” If your Tupperware was made during or before the 1980s, there is a good chance contains more than just BPA. Until recent years, manufacturing processes were allowed to go unwatched by the eyes of certain regularity organizations. This means that dangerous chemicals, such as arsenic, lead, and mercury could be present in some vintage Tupperware containers.
