Method of recovering byproduct heat during composting

A method of recovering byproduct heat from a compost stack while the compost stack is in a bacteria active stage, the method comprising the steps of:

• a) providing a composting system comprising:
• 1) a plurality of aeration plates to receive the compost stack thereupon;
• 2) a support surface to provide for receiving the aeration plates in a single layer;
• 3) a perimeter barrier surrounding the single layer of aeration plates;
• 4) a manifold conduit area between the support surface and the single layer of aeration plates and at least partially surrounded by the perimeter barrier;
• 5) numerous air passages from the manifold conduit area through the single layer of aeration plates;
• 6) air flow means to provide for moving air flow within the manifold conduit area;
• b) providing heat recovery means to provide for transferring heat from beneath the compost stack to an external usage;
• whereby the compost stack produces heat as a byproduct of the bacteria active stage and the heat recovery means transfers the heat for the external usage.
