You can’t yourself, but if you heat the compost it’s possible.

Our city takes bones as well as dog and cat poo as well as a host of other stuff you can’t compost personally since it’s a heated above 55c and breaks down all that extra stuff.

Municipal compost is put through a tub grinder, which masticates everything to a fine degree. So even there, it’s not really the heat. They are just grinding it to the point where you can’t distinguish it from other bits of rock and silica in the soil.

Also, I’ve gotten my home compost over 160 degrees F which is considerably hotter. I mean the same pile that these bones have survived.

Municipal compost shouldn’t be accepting those items if it’s not heated since it doesn’t break down, nor does it kill pathogens off that can be deadly if used for vegetable gardens.

Heating it in specially designed containers with controlled environments is a little different than the center of the pile getting that hot for a few hours during a hot day.

It’s a stare of the art facility that’s brand new, they’re a little different than most other municipalities.

I’m not saying the facility doesn’t get hot. It is for sure hot. I’m saying it is not the heat that breaks down bones, but the masticators they use.

Without the heat it still takes months to years to break down, with the heat it can done in the 21 day cycle.

It’s a culmination of everything, which is why it’s not really possible to do yourself.

When I say my pile was 160 I do not mean for a few hours on a hot day as you said. It was over 140 for a period of 3 weeks and peaked at 160 for about 5 days. Bones came out of that intact.

Heat + bacteria will not make bones disappear in 21 days or 210 days.

Maybe read the resource I sent you? Thats factually incorrect, bones do break down, why do you think there’s not trillions of bones all over the earth right now? Because they break down…. The heat exacerbates the break down cycle from months and years to weeks. You lacked the right conditions, that’s why you still had bones, it’s not because they don’t break down, they do. YOU can’t do it, but it absolutely is possible dude.

You seriously think your anecdotal experience is proof when there’s lots of actual physical proof they do break down….? Seriously dude …?

And no, your pile wasn’t that hot, it’s physically impossible for the entire pile to be a consistent temperature throughout its entirety, that’s only the center of the pile. You need the entirely of the pile to be consistent temp for the right conditions. Which again, almost impossible to do without sealed containers and specialized equipment you can’t really get yourself. But you can.

The incredibly ironic thing is, too much heat also kills off the good bacteria… so yeah you really don’t k ow what you’re doing or why if you’re letting it get that hot in it’s core anyways.
