ABSTRACT:
In a composting process, a heat conductive ventilation hood overlying a compost pile undergoing active composting. The hood is shaped so that process air emanating from the pile contacts the undersurface of the hood while ambient outside cool air is caused to traverse the upper surface of the hood. As a result of this heat exchange arrangement process air is dehumidified while concomitantly the ambient air is heated. The hood is pitched to cause condensate to run down its surface and not to drip. Warmed ambient air is used to heat the composting facility and dehumidified process air and condensate is reused in the composting process.
