Compacting device for inorganic solid urban waste

A compacting device for inorganic urban solid waste for reducing sizes and volumes of hollow and bulky bodies, the compacting device having a modular-type construction and comprising:

• a collection and compaction container for receiving a package;
• a compacting unit removably assembled to the collection and compaction container, the compacting unit including waste compressor means positioned against a stationary striker wall of the compaction container, the compressor means comprising at least one double-acting linear actuator having a rod carrying a compression plate, said compression plate cooperating with an opposite stationary striker surface formed on an opposite side of the collection and compaction container, the compacting unit further comprising a tubular jacket member coaxially movable inside a package in the collection and compaction container in a filling direction thereof, the jacket member being superimposed to an inner side of a peripheral wall of the package when the jacket member is inserted in the package, thereby forming a waste compaction chamber which is not in direct contact with the walls of the package, the compression plate being movable inside the jacket member and capable of remaining inside the package during withdrawal of the tubular jacket member for keeping compacted material in place in the package.
