Dear Sandra, the major part of bones consists of minerals which can be used for making a high quality ceramic material called bone china.. But the the cavities in the bone itself are full of organic fermentable material. One can crush the bones and introduce them directly into a biogas plant but one must also have a mechanism to remove the residual bones from the digester. By boiling the crushed bones, one can recover the water soluble part from them. Yours A.D.Karve
