You can alternatively make bone broth out of your bones. After several hours of boiling your bonesthem, you’ll have a mineral and nutrient-rich broth in addition to significantly softer bones that are easier to decompose. Some people put the bonesthem through two rounds of boiling at which point the bones crumble in your hand (which when salted become chewy calcium snacks for both canine and children). The crumbled bone are now easily compost-able.
