A gas sorbing system is formed by gas sorbing components which are dispersed in a polymeric matrix which is porous or permeable to the gases to be sorbed. It is a quarter-wave coating with a predetermined reflectivity, preferably between 0 and 10% and consists of or comprises SiNx:H. As a result, refuse is dumped further into the container or vehicle hopper, which minimizes the number of packing cycles required as multiple refuse carts are emptied.
