NOVELTY - The compost ventilating apparatus comprises a compost heap (2) having compostable material, ventilation pipes (4) and an air moving unit (6), and an air treatment unit for treating the air drawn from the ventilation pipe to reduce odors in gas before the gas released to an atmosphere. The ventilation pipe comprises a connection end (10), a ventilation portion (12) and a pipe wall for gas. The ventilation portion comprises aeration holes (14) extending through the pipe wall. The ventilation portion is located within the compost heap and the connection end.    USE - The apparatus is useful for ventilating heaps.    ADVANTAGE - The apparatus provides improved ventilation of the compost heap, which avoids hot spots/areas of high or low aeration, and the ventilation of compost heaps and windrows to reduce odor of gas.    DETAILED DESCRIPTION - The compost ventilating apparatus comprises a compost heap (2) having compostable material, ventilation pipes (4) and air moving unit (6), and an air treatment unit for treating the air drawn from the ventilation pipe to reduce odors in gas before the gas released to an atmosphere. The ventilation pipe comprises a connection end (10), a ventilation portion (12) and a pipe wall for gas. The ventilation portion comprises aeration holes (14) extending through the pipe wall. The ventilation portion is located within the compost heap and the connection end, which is coupled to the air moving unit. The air moving unit causes movement of air through the aeration holes of each ventilation pipe when the unit is active. The ventilation pipe is extended vertically above the compost heap with the connection end. The ventilation portion is arranged at or adjacent to an end of the ventilation pipe or each ventilation pipe opposite to the connection end. The air moving unit draws an air from the ventilation pipe. INDEPENDENT CLAIMS are included for:    (1) a method of ventilating a compost heap using ventilation pipe and an air moving unit; and    (2) a ventilation pipe.    DESCRIPTION OF DRAWING(S) - The diagram shows the windrow compost heap:    Composting apparatus; (1)    Compost heap; (2)    Ventilation pipe; (4)    Air moving unit; (6)    Connection end; (10)    Ventilation portion; (12)    Aeration holes.
