Case Studies - Bones

Mike Callicrate (Ranch Foods Direct) a rancher and meat processor from Colorado Springs had a problem with disposing of cattle bones left over from meat production.
He wanted to know if it was possible to pyrolyse the bones, crush them and then add the crushed carbonised bones to the soil as biochar.
As we were travelling to the USA anyway, It seemed like an ideal opportunity to meet Mike.
Mike flew to Ohio with a box of bones and using the first licenced machine to be built in the States, we added the bones together with some wood to one of the trial burns.
The bones completely carbonised, even the teeth. The photo shows Mike holding a carbonised skull.
A further burn using only deer bones (no wood) was equally succesful.
Although the bone charcoal burns well on a BBQ, we think there may be some customer resistance.
