• This method can be carried out particularly advantageously by a device according to the present invention.
• the invention is based on the finding that it is particularly advantageous to collect and compact waste if the compaction is not only carried out by sucking the air out of the waste bag, but in particular by additional simultaneous mechanical compression of the waste bag and pressurizing the same with compressed air. This leads in a simple way to waste with a particularly small space requirement and thus the best possible use of resources.
• the device according to the invention for collecting and compacting waste comprises a container for receiving a waste bag.
• Typical containers are known in the art and are typically generally cuboid or cylindrical in shape.
• the container comprises an opening, typically the top side, which is preferably complete, and side walls, typically the 4 side walls of the cuboid or the lateral surface of the cylinder, and a container floor.
• the container is airtight when the opening is closed. This means that the side walls and the container floor or the sliding floor panel form an airtight space inside the container if the opening were closed airtight.
• Suitable materials are plastics or metals, in particular glass fiber reinforced plastics, e.g. GRP 30 or GRP 40, PEEK plastics, PA6, as well as stainless steel or aluminum.
• the container of the device according to the invention also has a first seal at the opening, typically on a surface of the top of the container perpendicular to the side walls (and parallel to the container floor).
• the seal is at the opening Circumferential, that is, encloses the entire opening of the container.
• This seal is capable of providing an airtight seal to the opening of a typical waste bag when interacting appropriately with the second seal on the lid. Suitable sealing materials are known in the prior art.
• suitable sealing materials are generally known to the person skilled in the art, typical materials include silicone, silicone foam, EPDM, NBR, CR, cellular rubber, foam rubber, fluoroelastomers, e.g. Viton®, fiber seals based on aramid fibers, e.g. KLINGERSIL®, PTFE (Teflon®), polyurethane (Vulkollan®), PVC and PMMA.

• a clamping frame is attached to the container by means of a hinge, for example, and encloses the entire opening of the container.
• the opening is freely accessible, so that a rubbish bag can be placed in the container, with the rubbish bag coming into contact with the first seal at the opening.
• the clamping frame or the clamping clamps are then closed and are thus able to fix the waste bag to the container.
• the first seal, with the covering waste bag is not or only partially covered by the means for fixing a waste bag, and in particular remains essentially accessible for interaction with the second seal of the lid.
• the first seal is contacted by the means for fixing a waste bag, via the waste bag if this is inserted, and in the closed position also lies completely between the first seal on the container opening and the second seal on the lid.
• the use of a clamping frame has the advantage that the waste bag can be placed neatly over the first seal on the container opening when it is inserted and fixed to the container using the means for fixing a waste bag, preferably the clamping frame or the clamps. This leads to high tightness when the second seal on the lid in the closed position comes into contact with the waste bag and possibly with the means for fixing a waste bag.
• the container of the device has a sliding base plate inside, which is typically essentially planar.
• the base plate is designed as a kind of piston that is movable within the container, ie perpendicular to the surface of the base plate, along the side walls, slidably arranged.

• the container is opened, it is hermetically sealed by the side walls (these are also airtight) and either by the base plate or at least by the container base.
• the container is said to be airtight if, with the opening closed, the container maintains a negative pressure of 500 mbar (absolute pressure inside) for at least 30 minutes below 800 mbar (absolute pressure inside).
• the container has an inlet opening for compressed air, which can be pressurized, preferably controlled by an inlet valve, with compressed air that is made available by the means for generating compressed air. Compressed air can thus be introduced into the interior of the container, which is airtight, via the inlet opening.
• a rubbish bag is slipped over the container opening and with interacts with the first seal, either via the means for fixing a waste bag or via the second seal of the lid in the closed position, the space between the waste bag and the container is hermetically sealed. Introduction of pressurized air into the space between the waste bag and the container and with the lid in the closed position thus leads to compression and thus compaction of the contents of the waste bag.
