Abstract
Abstract The arrangement for the pre-sorting of household garbage comprises replaceable garbage sacks which consist of at least two sectional sacks having different distinguishing marking and forming separate garbage compartments which can be separated from each other. As a result of these steps it is possible to pre-sort resulting refuse consumer-just even more carefully and extensively in order to then dispose of the garbage components through recycling, decomposition and more ecologically-favourable incineration.
