Do metal lids go on the jar or separately?

Separately, and loose. Take the lid and ring off and put the metal in with other metals; a lid left screwed on will not be sorted correctly. Plastic lids, liners, and gaskets normally go in the trash. If the package tells you to replace the lid before recycling, follow your municipal program instead, since those on-pack instructions frequently conflict with local rules.

How clean does a jar need to be?

Clean enough that it does not smell or attract pests, not spotless. Scrape the solids out and rinse. Sticky residue in a bin causes real problems at a facility; a faint film does not. Do not run jars through a hot wash cycle for recycling's sake, since the water and energy outweigh the benefit.

Can I reuse pasta sauce jars for canning?

For dry storage and refrigerator use, yes. For actual home canning, no. The National Center for Home Food Preservation advises against reusing commercial food jars for canning because they are not designed for repeated heat processing and break at excessive rates in pressure canners. Use jars made for canning, such as Ball or Mason, which are built for it.

What do I do with candle jars?

Get the wax out first, since residual wax is a contaminant. Freezing the jar usually makes the wax pop loose, or you can warm it and wipe it out. Then check your local rules, because some programs exclude candle jars entirely regardless of how clean they are. If the wax will not come out, the jar goes in the trash.

Are jars worth more than bottles to recycle?

No, they are the same material and the same value. Color matters more than shape: clear flint glass is the most useful because color cannot be removed once it is in the melt. Both bottles and jars face the same collection problem, where glass gathered separately becomes new products far more often than glass thrown into a mixed cart.

Quick answer

Scrape them out, rinse, and take the metal lid off, recycling it loose with metals rather than screwed on. Labels stay. Jars are the same soda-lime glass as bottles and go the same route. Two catches: some programs exclude mason and candle jars, and a commercial food jar should not be reused for home canning.

Recycling route: Check locally

How to Prepare

1Check whether your program takes glass, and whether it excludes mason or candle jars specifically
2Scrape out food and rinse; clean enough not to smell, not surgically clean
3Unscrew metal lids and rings and put them loose in with metals, never left on the jar
