The invention claimed is: 1. Waste container for mechanical waste collection comprising a generally rectangular body (1) with a closed bottom end and an open upper end, a lid (2) correspondingly shaped to fit onto therein of said open upper end of the waste container for a tight closure thereof whilst in a closed condition, a foot operated lever (3) being provided at the bottom of the container with pivotal connections (4) at the rear of either one of the lateral sides of the waste container and an upwardly linearly projecting pedal (5) at the frontal side thereof, said foot operated lever (3) being pivotally connected at an intermediate location (6) thereof to upwardly extending connecting rods (7) at each one of the lateral sides of the waste container, said upwardly extending connecting rods (7) thereby transmitting movement of said foot operated lever (3) to a lid control device, characterised by that said lid control device enabling a 90° swinging movement of said lid (2) during opening or closing operation thereof, said lid control device having located in each one of the lateral sides of the waste container a first frontal rod (10) extending from a frontal point of pivotal connection (12) at a frontal protrusion (2a) of said lid (2) to a rear point of pivotal connection (8) to said upwardly extending connecting rod (7), said first frontal rod (10) being further rotatably mounted onto the body of the waste container (1) at a fixed junction (9) in proximity to said rear point of pivotal connection (8) to said upwardly extending connecting rod (7) and a second rear rod (11), said rear rod (11) having an L section configuration extending from an upper point of pivotal connection (13) at a rear protrusion (2b) of said lid (2) to a lower point of pivotal connection (14) to a rear protrusion (1a) of said waste container (1), said fixed junction (9) of the frontal rod (10) to the body of the waste container (1) acting as a fulcrum for the rotation of said frontal rod (10), wherein a downward movement of connecting rod (7) in response to a single instantaneous pressing of said pedal (5) of the foot operated lever (3) exerts a pulling action on said frontal rod (10) and causes a clockwise rotation thereof and a swinging movement of said lid (2) simultaneously around said fixed junction (9) of said frontal rod (10) to the body of the waste container (1) and around said upper point of pivotal connection (13) and said lower point of pivotal connection (14) of said rear rod (11), a compression spring (18) being provided for a decelerated return of said lid (2) during a predetermined final arc of the anticlockwise rotation thereof prior to arriving at the closed position, one end of said compression spring (18) being mounted onto said rear rod (11) of the lid control device and another end of said compression spring (18) being free to come in contact with the rear surface of the body of the waste container (1) during said predetermined final arc of the anticlockwise rotation of the lid prior to arriving at the closed position, said final arc of angular displacement of the lid being equivalent to approximately two tenths of the overall angular displacement thereof, said compression spring (18) thereby decelerating and averting possible accidents due to interposing of a hand or head in the course of closing of the lid, said waste container further including means of securing said lid (2) at the fully opened condition to facilitate mechanical waste collection operations. 2. Waste container according to claim 1, wherein said means of securing said lid (2) at the fully opened condition to facilitate mechanical waste collection operations is a manually operated hooking means (21) at the rear of the waste container that connects said lid (2) to the body of the waste container (1). 3. Waste container according to claim 1, wherein said means of securing said lid (2) at the fully opened condition to facilitate mechanical waste collection operations is a manually operated lever (22) provided as an extension of said foot pedal (5) that blocks said foot operated lever (3) as the waste container is overturned for emptying the contents thereof and thereby maintains the lid thereof in the opened condition, wherein said manually operated lever (22) may further be adapted to work as a hand operated lever for effecting the lid opening and closing operations. 4. Waste container according to claim 1, further comprising a spiral return spring (15a) fixedly mounted between positions (19), 20 on the body of the waste container (1) and on the frontal rod (10) of the lid control device, wherein exertion of pressure upon said pedal (5) of the foot operated lever (3) results in the performance of a rearwardly clockwise swinging movement of 90° of said lid (2) from the closed to the fully opened position, whilst release of said pedal (5) of the foot operated lever (3) results in the performance of a forwardly anticlockwise swinging movement of 90° of said lid (2) from the fully opened to the closed position under the action of said spiral return spring (15a). 5. Waste container according to claim 1, wherein an end of stroke position during pressing downwards of said foot pedal (5) corresponding to the bottom dead center of said foot operated lever (3) is an intermediate position of unstable dynamic equilibrium of said lid (2) during a clockwise rotation thereof in the direction of opening and equivalently during an anticlockwise rotation thereof in the direction of closing, said intermediate position of unstable dynamic equilibrium being the position at which said points (6, 8) of pivotal connection of said upwardly extending connecting rod (7) lie along the same line with said fixed junction (9) of pivotal connection of said frontal rod (10) to the body of said waste container (1), wherein a rearwardly clockwise swinging movement of said lid (2) in the direction of opening is initiated upon pressing downwards of said pedal (5) of said foot operated lever (3), the stroke of said foot operated lever (3) being terminated as the lid (2) arrives at said intermediate position of unstable dynamic equilibrium wherefrom said lid (2), due to the acquired momentum and to the pivotal connection of the rear end thereof to said rear rod (11), continues the swinging movement thereof in the same direction until it eventually reaches the fully opened condition having completed a swinging movement of 90°, whilst said foot operated lever (3) returns to the top dead center thereof and wherein a reverse forwardly anticlockwise swinging movement of said lid (2) in the direction of closing is initiated upon pressing downwards of said pedal (5) of said foot operated lever (3), the stroke of said foot operated lever (3) being again terminated as the lid (2) arrives at said intermediate position of unstable dynamic equilibrium wherefrom said lid (2), due to the acquired momentum and to the pivotal connection of the rear end thereof to said rear rod (11), continues the swinging movement thereof in the same direction until it eventually reaches the fully closed condition having completed a swinging movement of 90° whilst said foot operated lever (3) returns to the top dead center thereof and may be used again in the direction of opening said lid (2). 6. Waste container according to claim 5, wherein the selection of specific locations for said pivotal connections (9, 12) of said frontal rod (10) and (13, 14) of said rear rod (11), as well as the selection of specific locations for said pivotal connections (4, 6) of said foot operated lever (3) and pivotal connection (8) of said connecting rod (7) to the frontal rod (10) is such as to obtain non obstructed movement of the lid during the 90° swinging movement thereof from the open to closed position and vice versa and further obtain preferred operational characteristics of substantially similar energy requirements both in the direction of opening and closing of the waste container and a practically equivalent stroke of said foot operated lever (3) and foot pedal (5) in the corresponding subsequent arcs of displacement of the lid from the opened condition to the intermediate position of unstable dynamic equilibrium and henceforth from the intermediate position of unstable dynamic equilibrium to the fully opened condition and vice versa. 7. Waste container as claimed in above claim 6, further comprising an arrangement of elastically loaded resilient spring means (15) being fixedly mounted and extending between said pivotal connection (12) of said frontal rod (10) to lid (2) and a point (16) onto the body of said waste container (1), a flexible end portion of said resilient spring means (15) being provided at the proximity of said fixed junction (9) of pivotal connection of said frontal rod (10) to the body of said waste container (1), said flexible end portion of the resilient spring means (15) lying in between a pair of shaft protrusions (17a) and (17b) located onto the frontal rod (10) and alternatively interacting with either shaft protrusion (17a) when the lid (2) is fully opened or with shaft protrusion (17b) when the lid (2) is closed, wherein interacting of said flexible end portion of said spring means (15) with shaft protrusions (17a) or (17b) is manifested as tension being imposed onto said spring means (15) due to a pressure exerted onto said flexible end portion thereof by either shaft protrusion (17b) when lid (2) is closed or by shaft protrusion (17a) when lid (2) is opened, torsional and/or bending stresses being exerted upon said resilient spring means (15) whilst said lid (2) moves past the point of unstable dynamic equilibrium either in the clockwise direction of opening or in the anticlockwise direction of closing, thereby leading to counter acting moments being built as the lid approaches the fully opened or closed position thereby facilitating the return thereof in the direction of closure or opening respectively, said counter acting moment applied during closure of the lid further having the beneficial effect of decelerating the lid and averting possible accidents due to interposing of a hand or head in the course of closing thereof, said lid control device presenting substantially identical energy requirements both in the direction of opening and closing of the waste container and practically equivalents strokes of said foot operated lever (3) and foot pedal (5) in the corresponding subsequent displacement of the lid (2) from the opened condition to the intermediate position of unstable dynamic equilibrium and henceforth from the intermediate position of unstable dynamic equilibrium to the fully opened condition and vice versa.
