A subsurface system for collection of refuse comprising various independent modules according to the type of refuse to be collected, comprising a cover and a post with an input bin on the surface connected with the cover located at a height suitable to the waste deposition, the cover supporting a paving wherein the cover opens up to 90 degrees by means of one or more electric or electro-hydraulic cylinders of the subsurface system combined with gas cylinders of the subsurface system, an underground bunker, said gas cylinders and said electric or electro-hydraulic cylinders are attached to the underground bunker and to the cover and having a drive action system electrically fed to allow the automated opening and closing of the lid up to 90 degrees, an internal platform fixed to the underground bunker and a container located inside the underground bunker liftable by means of a side loading lifter of a collection truck, wherein the container has two mechanisms installed on two opposite sides, characterized in that each one of said mechanisms consisting of - one movable arm with a pin connectable with the side loading lifter and a roller installed in the top of the movable arm, said roller movable on channels installed in the cover and - a fixed arm with another pin also connectable with the side loading lifter; wherein between the fixed arm and the movable arm of each of the two mechanisms is installed a spring in the interior of the said fixed arm responsible for the mechanism movements; wherein the rollers of the movable arms are movable on the channels due to opening or closing of the cover, respectively extending or compressing the springs and translating vertically the movable arms out of the underground bunker or into the inside of the underground bunker allowing the container to be extract or introduced in the underground bunker, wherein the lifter of the truck is configured to be connected to the pins installed in the movable arms and the internal platform is composed of two movable elements positioned between the walls of the underground bunker and the walls of the container, a gas shock absorber attached to the underground bunker and to each of the two movable elements, two electromechanical locks attached to each of the opposite sides of the underground bunker, wherein said gas shock absorber is configured such that the two movable elements swing into horizontal position due to the force of a gas shock absorber and approach to the two electromechanical locks when both of said elements are in horizontal position. - one movable arm with a pin connectable with the side loading lifter and a roller installed in the top of the movable arm, said roller movable on channels installed in the cover and - a fixed arm with another pin also connectable with the side loading lifter; wherein between the fixed arm and the movable arm of each of the two mechanisms is installed a spring in the interior of the said fixed arm responsible for the mechanism movements; wherein the rollers of the movable arms are movable on the channels due to opening or closing of the cover, respectively extending or compressing the springs and translating vertically the movable arms out of the underground bunker or into the inside of the underground bunker allowing the container to be extract or introduced in the underground bunker, wherein the lifter of the truck is configured to be connected to the pins installed in the movable arms and the internal platform is composed of two movable elements positioned between the walls of the underground bunker and the walls of the container, a gas shock absorber attached to the underground bunker and to each of the two movable elements, two electromechanical locks attached to each of the opposite sides of the underground bunker, wherein said gas shock absorber is configured such that the two movable elements swing into horizontal position due to the force of a gas shock absorber and approach to the two electromechanical locks when both of said elements are in horizontal position. wherein between the fixed arm and the movable arm of each of the two mechanisms is installed a spring in the interior of the said fixed arm responsible for the mechanism movements;
