What to do about old peanut butter jars?

What's up! I wanna find out if there are any sustainable ways to use old peanut butter jars for every day use.  One thing I could use it for is to use them to pins and stuff. Any other ideas? Please drop some examples in this forum. Thanks!

I reuse them for dry food storage.

I reuse glass jars for preserves - jams, chutney and bottled fruit.

Twist top replacement lids can be easily purchased separately for 300g; 500g and 750 gr jars and they are safe for water bathing the preserves if required.

Like Pearl, I use the larger jars for storing dry goods.

Glass or plastic? The glass ones I get I often use for putting leftovers in the fridge in, along with the suggestions others already made. We have a few straight tall ones that are particularly good for pouring broth in to get the fat off the top.

Plastic is harder - most plastic P-butter jars are too low temp to even go in the dishwasher. I would hesitate to put anything hot in them.
Also, plastic lets gasses through more than people think - I used some for dried fruit and it picked up a lot of humidity.

However, I cut holes in one side to make feeders for my friend's banty chickens. Their houses aren't that big, and yet they needed enough feed capacity that they could last between her visits to feed them.

I only have plastic right now. How I use this stuff for preserving food, etc?

I fill peanut butter jars with bone broth.

I don't even bother with washing the leftover peanut butter out.

So my bone broth is "broth with peanut butter flavor".

Bone broth? What I do with it?

My dogs would love that

In plastic, dry storage is safest. Wash and dry the jars well, use them for dry things like beans, grains, flour, salt, etc. Fill them tightly, screw the lids on tight. they are airtight and I have never had bugs or moisture get in them.

Basic recipe for bone broth

Collect up bones from meals - chicken carcasses, pork bones etc and freeze if you don't have enough
When you have enough, put them in a large pot/slow cooker with water to cover and any of the following:
3 dandelion leaves,
a few herb leaves like sage, oregano, marjorum, parsley or thyme - fresh or dried
onion skins
bits of celery
carrot tops

Let it simmer covered for 4-6 hours, then remove the cover so it starts to thicken for another 4 hours.
Strain it to remove all the bones.
Thicken more depending on what you plan to use it for.

USES
1. Just drink it as a hot drink instead of coffee - it's full of calcium and other bone strengthening ingredients and lots of micronutrients.
2. Mix some into the water you're cooking rice in - it will make the rice more nutritious and give it a nice flavor.
3. Use it as a base to make soup. If you're making a commercial canned or packaged soup, replace some or all of the water with bone broth.

It can be frozen - just freeze it in quantities you're likely to use. I freeze mine in a mix of 1 or 2 cup measures, but my friend also freezes some in ice cube trays then bags the cubes for when she's making Korean version cup-a-soup.

We use them to put what we are going to compost we have 2 and once they fill up we take them to the composter site. Works great when you want to compost but too busy in the mornings to do everything before leaving for work.
I use the rest of the plastic jars and prescription bottles to store craft supplies, seeds, or dry leaves (mint, celery, thyme etc that I deshidrate during spring summer)
