For reasons of environmental protection, the carefully directed collection and further processing of wastes is absolutely necessary in order, on the one hand, to minimize the amount of waste being created and, on the other hand, to facilitate a removal which protects the environment. Thus, demands made on the suitable collecting containers have also increased. The collecting containers must thereby be in particular adapted to the type of waste and must be adjusted to the waste.
In former times, waste removal was done such that the waste or garbage was collected in very simple containers (garbage cans) and was transported unsorted. In the meantime, special designs for waste-collecting containers have been developed, which in particular are adapted to the respective waste-removal vehicles in order to enable at least a partially automatic emptying of the containers. At this point the different container shapes are being pointed out. Furthermore, special collecting containers were developed for some raw material types, for example to collect old paper, old glass, and others.
In the course of the desires to minimize the volume of waste, tests have been conducted which revealed that among others, the average household waste includes well over 40% of compostable material which, among others, in view of the limited capacities of dumping sites, however, also for environmental protection and recycling reasons, should rather be subjected to a composting process in order to allow these waste materials to decompose in a natural cycle. The conventional collecting containers are not suited for collecting compostable wastes since the waste materials become too moist, rot and/or decompose in some other manner in the known containers so that, on the one hand, a composting cannot take place and that, on the other hand, bothersome effects, in particular odors occur.
The collecting of compostable wastes in common composting containers used in gardens or on farms is not possible for waste removal since often there is no space available for such containers and since these containers cannot be emptied using common waste-removal vehicles.
