Plastic-free food storage that actually works
Glass for anything you reheat, steel for anything that travels, and a plate on a bowl for most of the rest.
4 swaps, highest priority first
Reheating in plastic tubs → glass containers
Heating food in plastic is the single clearest route for plastic particles into what you eat. Glass fixes it.
Swap first · about 600 g of plastic a year
Cling film → lidded containers or beeswax wraps
Cling film is single-use plastic in direct contact with food. A plate on a bowl does the same job for free.
High priority · about 400 g of plastic a year
Plastic lunch box → stainless steel
Steel lunch boxes last for years, go in the dishwasher and don't stain or crack.
Worth doing · about 100 g of plastic a year
Freezer and sandwich bags → jars and tins
Single-use bags add up fast. Jars, tins and paper handle nearly every job.
Worth doing · about 500 g of plastic a year
