You should discard or replace a baking sheet if it develops rusted spots, has a non-stick coating that is peeling or deeply scratched, or is warped to the point where it rocks or cooks food unevenly. Otherwise, dark, stained, or slightly dented sheets are perfectly safe and work well.
If your cookie sheets are bent or cracked, they need to be replaced. Bent or cracked cookie sheets will cause your baked goods to bake unevenly. Even a dent in a cookie sheet can cause problems. If your nonstick cookie sheets are peeling or chipping, it's time for new ones.
Old pans: "Older pans are not as safe as new ones because of the increased wear and tear, which removes the natural oxide protective coating, and the higher amount of scratches can increase the chances of aluminum leaching into food," Le says.
Kitchen items and cookware
Reuse it: if it's in good condition, take it to a reuse drop off point. Or you can sell, donate, pass it on. All kitchen items and cookware (such as pots and pans, cutlery, utensils, baking trays, mixing bowls etc.) can be taken to your local recycling centre.

Because baking paper cannot be recycled, it is disposed of in the residual waste bin and then incinerated.
Non-recyclable items

Soft drink cans and canned food tins are made from aluminum, a material that can take between 10 and 100 years to decay, depending on the thickness, and which generates iron oxide. For this reason, it is important the waste recycling.
Here's why it matters: 1️⃣ Even Heat Distribution Light-colored, uncoated aluminum reflects heat instead of absorbing it — which helps your cookies bake evenly top to bottom. 2️⃣ No Burnt Bottoms Dark pans absorb heat and can cause the bottoms to brown or burn faster than the tops are done.
Let the Cookies Cool Before Removing
Cookies are more likely to break or stick when they're still hot and soft, so allowing them to cool slightly on the baking and cookie sheet is key. Cool for 2-3 Minutes: After removing the cookies from the oven, let them cool on the sheet for about 2-3 minutes.
