In most landfills in the Third World, crumbling remains very common. To the material recuperates can be added some poor who feed on the landfill in Brazil, some have even been suspected of consuming, after cooking, anatomical remains from a hospital), others take leftover food; some raise livestock on the site, others collect and take food for their animals. There are squatters who settle with their families, who store the collected materials there and who make them undergo, if necessary, a first transformation: pressing or another method to reduce the volume, washing, burning, etc.
The activity of adults is added to that of children. With regard to the initial deposit, the crumpling of streets has already resulted in a first creaming, or often already several successive creaming. Again, junk removal melbourne fl on the landfill, on what remains, some recover first, others in second, on ” the rest of the rest, “etc., following a ” cascade ” operation, associated with economic and social slopes, up to ‘under the most miserable conditions. in fact, what they are selling them is a ” right of first refusal ” which guarantees them the primacy of sorting. Collection operators, especially those who collect wealthy neighborhoods, thus find additional remuneration.

The application of these measures led to the virtual disappearance night dressers, partly for the benefit of said pickers ushers, who negotiated their place with the caretakers of buildings. Street ragging was then increasingly regulated, then banned; this prohibition was first more or less respected; then, gradually, ragging streets became a very marginal practice. The ban on ragging was based on various arguments: embarrassment for the municipal service, reasons of health and safety, and also property of the deposit, whose rag pickers are skimming.
However, it can be observed that those responsible for recycling centers are still obliged today to deal with certain groups (in particular gypsies); in order to avoid incessant deterioration, the managers look with them for a modus by letting them recover under certain conditions. In the past, countries in the North have experimented with technologies for the systematic, mechanized, or even automated sorting of raw household waste, that is to say, the subject of the unitary collection.
These attempts ended in failure, due on the one hand to the complexity of the processes, junk removal melbourne fl on the other hand to the soiling of the materials extracted for recovery purposes: moisture absorption of paper and cardboard, adherent materials, etc. , in the first place due to extensive compaction of the waste in the collection bins. A first alternative consists in carrying out, again on raw garbage (collected in the mixture), manual sorting, at least in part.
The industrial countries have gradually abandoned this route because, in addition to the soiling of recoverable materials, the poor sanitary conditions which result for the workers who carry out sorting. Since then, these countries have turned to selective collection upstream, which requires separation by the inhabitants, at the pre-collection stage. These are single-material collections, in particular for glass and in part paper and cardboard, which are the subject of voluntary contributions in specific containers, or multi-material collections, generally door to door, which mainly concern various types of packaging.
