Waste as a whole is more than ever a global problem. Consumer society has encouraged the use of raw materials to manufacture various objects, which are then either thrown into the sea (the 7th continent of plastic in the Pacific) or buried (in disused quarries or landfills) without any thought of reusing them.
This waste can be inert, non-hazardous, or hazardous, even highly hazardous, and is always bulky.
The eternal question is: how do we want to leave the planet to our children? It is a question to which we ALL must provide a quick and valid answer.
For several years now, there has been talk of landfill, then treatment (at waste production sites or specific locations); this raises the issue of waste transport, hence the problem of illegal dumping. Regulations are advancing, and as raw materials become scarce, there is talk of waste recovery (since some types of waste are becoming valuable). A logical chain is being created: waste production (production waste, demolition waste, etc.), waste sorting (on site or at specific locations), final waste going to destruction, treated waste gaining value and returning to use.
All of this will make up the life of a piece of waste... But above all, isn't the best waste the waste we don't produce?
