Abstract
A refuse compression apparatus for reducing the volume of a thermal elastic refuse includes a telescopic refuse container which is covered by a bag and is housed in a cylindrical housing and suspended on the top of the cylindrical housing. A top cover box is coupled with the telescopic refuse container and the cylindrical housing so that the bag divides the inner space of the cylindrical housing into a free space inside the bag and an airtight space outside the bag. An air pump provided to connect the airtight space and the outside of the cylindrical housing operates to pressurize the airtight space and cause the bag to press the telescopic refuse container upwardly. Thus, the refuse placed in the telescopic refuse container is pressed against the lower surface of the top cover box and is compressed.
