There is a pretty good video on YouTube from a younger person recycling HDPE plastic. It is pretty easily formable at 350F, so can be melted in a common oven.

Do you need to worry about offgassing if you do this or is it generally safe as long as you melt it rather than burning it?

I love that the kid is using his parents actual oven :D

Someone recommended using my home oven for baking open my headlamp enclosure. The idea is to melt the glue holding the lens in place so you can e.g. add bmw halo lights to your headlamp. Problem is that glue is likely toxic then you’re cooking food in it later. So I wouldn’t try that, esp when an old electric stove w/ oven can be had for $50 that can run in your backyard

When my dad had a shop that is what we did, got an old electric oven. Had it setup so we could take off the door and use thermal blankets to cover large metal pieces we'd treat that were larger than could fit in one bake.

Well done narrative and video. Thank you for sharing this.
