The plastic-free kitchen: what to swap first
Heat is what turns kitchen plastic from a waste problem into an exposure problem. Start with anything that gets hot.

Start with anything plastic that gets hot or gets cut. Heat and abrasion are the two things that release the most plastic into food, and the kitchen has plenty of both.
The three swaps that matter most
- Stop reheating in plastic tubs. Use glass, or reheat on a plate with another plate on top. See reheating in plastic → glass.
- Replace your plastic chopping board with hardwood. Knives cut plastic fragments straight into food. See plastic board → hardwood.
- Retire nylon utensils for wood or steel. Hot oil softens them. See nylon utensils → wood or steel.
Then look at pans and kettles
Non-stick coatings are PTFE, a fluoropolymer plastic. They wear out, and when they do, replace them with stainless steel, cast iron or carbon steel rather than another non-stick pan. See non-stick → steel or iron.
Plastic kettles boil water several times a day. Many "steel" kettles still have plastic in the water path, so check the lid interior, filter and water window. See plastic kettle → steel.
What not to worry about yet
Plastic handles, knobs and appliance casings that never touch food are low priority. Don't replace working items early just to remove plastic that doesn't touch what you eat — use them until they wear out.
Hidden plastic to watch for
- Bamboo boards and tableware — usually glued or bound with plastic resin.
- Silicone — spatulas, bakeware and seals are silicone, which counts as plastic under our definition.
- "Ceramic" non-stick — a coating, not solid ceramic.

Top swaps in kitchen & cooking
Plastic chopping board → hardwood board
Knives cut tiny pieces off plastic boards and into your food. A hardwood board avoids that and lasts for years.
High priority · about 200 g of plastic a year
Nylon spatulas and spoons → wood or steel
Hot oil and pans soften plastic utensils. Wooden and steel ones don't melt, chip or leach.
High priority · about 60 g of plastic a year
Plastic kettle → steel kettle with no plastic in the water
Boiling water in plastic several times a day is one of the most frequent heat-plus-plastic contacts in a home.
