NOVELTY - Process for handling a device for aerobic treatment of heaped or stacked material (12) involves providing a covering construction (10) having a cover comprising several support elements (22) which can be filled with fluid and are connected to one another at least in part, and waterproof and gas-permeable sheet (14) connected to support elements; erecting covering construction by filling the elements with fluid at a pressure which raises the sheet and forms a space (30); introducing the material into the space; and lowering the construction by emptying fluid from the support elements.    USE - For handling a device used for aerobic treatment of organics containing waste e.g. residual waste or domestic refuse in a compost heap.    ADVANTAGE - The covering construction forms a device which can be erected in a flexible manner for the aerobic treatment of heaped or stacked material in which the covering construction covers the material. The device has an erected state and a lowered state. The construction and flexible device makes an inexpensive, simple and gentle handling of the cover possible. The device combines the advantages of a closed system with the advantages of the known simple heap covering. Even in the erected state the device remains very largely closed off from the environment. This is because the sheet of the device is not only stretched out around the compost heap in the erected state but also lies on the compost heap or is piled around the heap in the lowered state, so that the heap is always-surrounded by the sheet. The polluted air thus remains within the device. An exhaust system can be installed for the first time in a heap covering, in order to capture by reduced pressure any emissions that might have been carried over by wheel loader traffic when the covering is in the erected state, and feed it to an adjacent exhaust air cleanup system. The device permits highly mechanized introduction and removal of the material to be covered involving minimum labor costs, since at most only one person with a wheel loader is required or the room is charged and emptied via automatic feed belts. The workers no longer come into direct contact with the material to be covered, which is an improvement in safety at work.    DETAILED DESCRIPTION - Process for handling a device for aerobic treatment of heaped or stacked material (12) involves providing a covering construction (10) having a cover comprising several support elements (22) which can be filled with at least one fluid and which are connected to one another at least in part, and at least one waterproof and gas-permeable sheet (14) connected to the support elements; erecting the covering construction by filling the support elements with at least one fluid at a pressure which raises the sheet and forms a space (30); introducing the material into the space; lowering the covering construction by emptying fluid from the support elements, where the sheet is lowered and the material is covered with the sheet; and removing the material from the space.
