<p>A method of treating waste animal materials comprises introducing the materials, preferably in comminuted form, into a vat (30), adding fly larvae, replenishing the waste materials as they are consumed by the larvae, adding fresh larvae when the existing larvae are mature, and repeating these steps until the vat is full. The remaining material, typically including bone and feathers, is then removed from the vat as a solid block, which can be broken up, dried and ground to particulate form for use as a fertilizer. A vat (30) with grooved inclined walls is preferably used, the mature larvae being thereby induced to migrate up the grooves for collection, leaving the newly-introduced larvae to consume the material in the vat.</p> |
