Seems like a shame to throw away and must have a use.
Depending on where you live, this may be the start of your plastic-free/no-waste journey. (You’d obviously need a place where you can shop plastic-free somewhere near you )

One possibility is that, any of these jars that were vacuum sealed in the first place, they can easily be re-vacuum sealed with a cheap vacuum chamber/hand pump combo. it’s not an appropriate preservation method for all the kinds of things that originally came in the jars, but will keep dry goods from oxidizing/etc.
Nice collecion you have there! Just got my hand on a large cardbox worth of jars. Almost all of them have caps as well. My plan is to slowly clean and fill them up, just like you did! Also I recently found out (by a foodwaste prevention program) that I have plastic-free shop not too far away from me.
Even if you don’t have a place like that, it’s still worth it to put the stuff in jars to prevent maggots from ruining everything.
I’ve slowly been adapting to this! I love having all my jars, it’s like living in a lab with specimens
I know you were probably joking, but as a PSA I will add that you NEVER dip any ‘bits’ or any body part in plaster in a closed, rigid container! 😬 A mold should be made with alginate, silicone, or other resilient material. The plaster is what would be poured into the mold afterwards, to make a casting. thanks.

Glass recycling is pretty good. Near complete recovery of the material. Plastic is basically impossible to recover, but glass and metals are generally very recyclable.
Just put it in the bin. Let the city recycle it. You’ll get it back as a beer bottle or another glass bottle like this one, or something else entirely.

Cum jar?
One man one jar. Please don’t look it up.
So I went looking for the date 1 Man 1 Jar was released and I found out that it has an IMDB page with predictably silly reviews. Technically it’s NSFW but it’s all text.
But yeah you’re like 15 years too late for me lol.

Life, uh, finds a way.
I once saw a video or a guy had a jar. I’m going to leave it a surprise but he put it somewhere. Maybe you could do that?
I save them up all year, and come Christmas / Lunar New Year, I bake cookies then hand out jars filled with cookies to coworkers and neighbors.
It turns out that my wife and I consume exactly enough jam in a year to balance out the jar egress for the maximum number of social connections we can sustain.
If I have a spare, I might make mango chutney. It doesn’t need to be vacuum sealed if you just make one jar and eat it reasonably soon.
I suppose you could engineer them to be solar garden lights too. There ought to be enough room for the panel on top of the lid, a battery and circuit on the underside, and then you hang an LED in there.
Do you happen to have a recipe for that mango chutney?
Not exactly! I just sort of take finely chopped apples (for pectin), onions, mango, and dried raisins or dried apricots. Then I boil, adding (a little) vinegar over time until it looks like chunky jam. Then I flavor it with soup stock and cinnamon to taste. Some nutmeg too, if you like. Finally I adjust acidity and sweetness with more vinegar or some sugar – but that’s usually not necessary if I add things in slowly.
If it’s too acidic, boil it longer, adding a little water if it gets dry. Vinegar (acetic acid) is a gas and will evaporate out slowly this way.
Mix frequently.
Ya know, for a friend…

This is how I store my collection of randomly sized screws, nuts, and bolts.
Make one of those sealed jar terrarium ecosystems.

Wash it, pour boiling water over it, put hot jam or other preserves inside, it will hold all winter. Just make sure the lid is concaved when the jam cools down - that means it seals well.
Wait, wait, wait!?! Wash it, then pour boiling water over it? Then put jam or whatever in the jar and it will be fine?!?
I’m not sure you’ve got all the steps in the correct order.
Instructions unclear, jam stuck in penis.
The hot water is to kill bacteria, of course you remove the water before you put the jam in. I have apple jam from 2022 canned using this method and it still holds, no mold and good taste.
I’m wodnering what seems so odd in this procedure because that’s how I’ve been taught to do it
I use old mason jars to store my whole bean coffee in the freezer until I’m ready to grind and use it.
A coffee aficionado can probably chime in on why this is bad, but uts the best use I’ve found for the jars.
AFAIK the best thing you can do to improve your coffee-freezing process is to prevent moisture from getting into the beans when you thaw. If you let it, moisture from the air will condense on the cold beans. So keep the beans in a closed, airtight container until they come to room temperature. (Airtight because water vapor is air.) So yeah, jars are good for this. Or sealed freezer bags should work too.
Good to know! Thanks! I vacuum seal what I can’t get in jars and let it all thaw freezer > fridge > ground.
Freezing is okay and helps for storage of big bags, but freezing and taking them out and putting them back in every day isn’t good because of the condensation.
But even then, it’s probably fine.
I don’t do that. I only thaw and grind enough for about a month’s consumption at a time. I got ~6 pounds of coffee for Christmas and only have a cup a day usually.
I was just providing my process because it seems, unintentionally, well designed to avoid condensation.
Nice!
Speaking of coffee, cold brew! Although I have two large mason jars and a metal filter that are designed specifically for that purpose.
I use them for grease after cooking. Or for drinking glasses when I can’t be bothered to run the dishwasher.
