Existing dumpster lids are difficult for a user to lift and also leak some water into the container. The lids also tend to become bent when dumping into a full garbage truck, as the lid presses against the mound of trash. The present invention provides a waste container and lid assembly comprising a lid having a pivot arm which operates on a pivoting surface attached to the side of the container and having a fulcrum. The pivot arm has first, second and third pivot points on its lower surface in order to move the pivot point as the centre of gravity of the lid shifts during opening to keep the centre of gravity ap- proximately over the pivot point. The lid is connected to the container by a two-piece hinge which swings the pivot arm clear of the supporting plates when the container is inverted. This alows the lid to swing freely on the two- part hinge which also permits the lid to move up or down while hanging in order to avoid damage to the lid if a solid mass is struck. The lid when closed is also able to slide forward to permit automatic unlocking.
