DESCRIPTION:
BRIEF SUMMARY
The invention concerns a method for collecting and disposing of wastes, in particular household wastes, in which the waste is collected separately, on the basis of material recycling criteria, in plastic-film receptacles which can be distinguished from one another by corresponding markings, and the plastic-film receptacles are taken to a central collection point for final storage and/or further use and there sorted according to their markings.
New laws and ordinances concerning the avoidance, reduction, reprocessing, and reutilization of garbage demand frugal use of packaging material, utilization of reusable packaging, and especially appropriate sorting, for recycling, of wastes which are produced. For this reason, there have already existed for some time containers, set up centrally by communities, into which end users can dump their waste paper and used glass.
Garbage sorting also takes place in households, a three-part separation into organic wastes, plastics, and other wastes usually being performed. Although this garbage separation contributes to savings in reusable materials, it entails problems with regard to "garbage hygiene." In other words, the distribution of garbage into different bins greatly increases the residence time of the garbage in the household, since the individual bins containing wastes of various kinds are emptied only at relatively long intervals. With organic garbage in particular, it has been found that storage of food residues in organic waste bins can lead, after only a few days, to contamination with spores, bacteria, maggots, etc. In addition, unpleasant odors can develop relatively quickly.
Furthermore, garbage separation as usually performed today also requires special garbage transport vehicles with chambers, separated from one another, for the various wastes, is such a way that must each be capable of being loaded with garbage and individually emptied. Garbage transport vehicles are accordingly of relatively complex configuration, and thus expensive. Alternatively, the bins containing the various kinds of garbage can also be picked up separately. This is, however, also complex and therefore expensive.
To eliminate this problem, it is proposed in EP-A-0 537 771 that the different garbage fractions be collected in correspondingly marked garbage bags, and the garbage bags be disposed of together with the garbage. The result of this feature is that the various garbage fractions can be carried off in a garbage vehicle but the latter does not need to be equipped with separate chambers, since the garbage fractions can easily be separated once again on the basis of the markings of the garbage bags when the garbage vehicle is unloaded. Problems nevertheless still occur with regard to garbage hygiene, since the individual garbage bags containing different types of waste are emptied only at relatively long time intervals.
It is therefore the object of the invention to configure a method of the kind cited initially for collecting and disposing of household wastes in such a way that, while retaining the requisite garbage separation, hygienic and less complex collection and disposal of household wastes is possible.
This object is substantially achieved, according to the invention, by the fact that:
a) the waste is packaged in portions, at the place where it is produced, by the fact that a plastic-film receptacle for the waste is produced, in the respective desired size, from a tubular film; and after filling, the plastic-film receptacles are heat-sealed and vacuum-packed; and
b) the heat-sealed and vacuum-packed plastic-film receptacles containing the various kinds of waste are temporarily stored, unsorted, in at least one common collection vessel before being taken, also unsorted, to the central collection point.
While with the known method the garbage is collected in relatively large garbage bags, which in single-family houses are generally located in the garage and in multi-family houses are provided at a central garbage collection point, and are sealed only in order to be carried
