The problem of not recycled garbage.
Despite the active development of waste sorting and processing, there are three big unsolved problems:
manual labor in sorting rubbish,
huge landfills that are virtually impossible to disassemble,
Jobs created by manual sorting of garbage - this is extremely harmful to health and low-paid work. In addition, the efficiency of this work is quite low.
This problem is likely to be solved in the next decade with the help of robotics.
The huge dumps of unsorted garbage that exist in all countries of the world, but especially in the countries of the "third world", can theoretically be disassembled. In the same third countries there is a lot of cheap labor ready to risk their health by rummaging in a landfill. The question is whether human civilization has the right to relate to representatives of its own species in this way. Well, if we care about cats and dogs, then people should be taken care of in the first place.
But there is a solution. And this decision applies both to the huge dumps of unsorted garbage, and the residual non-recyclable garbage that occurs at this stage with any, even the deepest sorting and processing.
And the solution is quite simple in technical terms.
You may have seen shots where utilized machines are converted into metal briquettes using huge presses and sent for re-melting.
Now imagine a mountain of unsorted rubbish or a mountain of residual rubbish, and maybe rock dumps in mines and open pits.
And imagine a very powerful press that is capable of compressing a mixture of various substances to a very high density, comparable to that of concrete, bricks, curbs or even metal.
Technically, this is possible.
A heavy-duty press into which unsorted or residual waste will be loaded can turn the waste into durable, very dense technical briquettes.
To prevent the release of any toxic substances from these briquettes, they will need to be lowered into molten plastic. The output will be hermetically and tightly packed garbage, safe for humans and nature.
Any, the most gigantic landfill will decrease in size by 2-3, or even 5 orders of magnitude when using this technology.
But that is not all.
From the press and bathtub with liquid plastic, humanity will receive building material.
It may not look very aesthetically pleasing, but there is no need to make facades or residential buildings out of it.
These briquettes can be used as a substrate, as a basis for asphalting of parking lots, roads, warehouses, airfields, ports and other industrial areas.
Briquettes can be used in the same way as the foundation for light buildings: hangars, gas stations, markets, garages, etc.
The presence of organic and liquid waste among unsorted waste does not prevent the creation of briquettes. Part of the liquid and organic waste will flow out of the press and will be treated by analogy with the treatment of sewage and wastewater. The other part remaining in the briquette will decay safely. The voids formed in this way will not be critical for the quality of construction. There are voids in concrete, and in bricks, and in the substrate of asphalt roads.
Additional advantages for people and the environment:
Dismantling landfills and garbage collection, by analogy with the collection of scrap metal, will turn into a source of income for the poor.
Creating spontaneous landfills will not be profitable. It’s better to give and receive money than to drop rubbish anywhere, and get a fine.
As a result, solve problems as:
safe waste disposal,
liquidation of waste recycling residues,
elimination of dumps (slags) of rocks.
As a result, 100% recycling of human waste will be achieved.
In addition, a new building material will appear that will replace those used, which will reduce the depletion of nature surrounding man.
