Tupperware and other plastic containers are usually labelled with recycling code number 5, but certain types of plastic containers may consist of different resins.
When should Tupperware be thrown out?
Tupperware containers have a reputation for lasting years and decades – that’s why the brand name has become so synonymous with food containers. That being said, there will eventually come a time when it will have to be disposed of. Here are some signs that your Tupperware needs to be replaced:
- Heavy staining – Tupperware that is used to store foods like curries or spicy foods can absorb the colours, staining the plastic.
- Persistent odours – Tupperware can develop a nasty smell from all the types of food they’ve contained. Strong unpleasant smells can also be a sign of bacterial residue or growth, which makes the containers unsanitary for use.
- Deformation – Like any plastic product, Tupperware can warp and change in shape when exposed to high temperatures, which can happen in the dishwasher or when used for excessively hot foods. This can cause the container to lose the integrity of its airtight seal and become unsuitable for storage.
- Missing or damaged lid – Probably the most annoying thing about Tupperware is that there’s always at least one orphan lid or container in the drawer. Don’t hold onto it for years waiting for the lid to magically appear! Containers that don’t have a lid are not practical for keeping food fresh. In the same way, a crack in a damaged lid also compromises the seal of the container, causing it to be prone to contamination or spills.
How to recycle Tupperware and plastic containers
1. Give it a good wash and clean to remove any leftover food residue or oils and leave it to dry.
2. Keep the lids and containers together when you set them aside as they will usually be made of the same material.
3. Lastly, double-check the recycling symbol on them to make sure that they can be recycled.
