I personally do not do separate collection of garbage. For what I need it. Tariffs for the removal of garbage are huge and there are no discounts for those who are engaged in sorting. Therefore, you correctly say, the state should interest people to do this.
In my city just starting to enter the sorting of garbage. People are not used to doing this and do not want to sort it.
If the authorities do not come up with measures to stimulate separate collection of garbage, then this will continue.
We have in some shops began to appear machines for collecting plastic bottles, for the delivery of bottles people are paid money. And in the store drinks in these bottles have an added value. I think this is a good example of a way out of the situation with the accumulation of garbage.
Paying people money for the given secondary raw materials is a very good method of stimulating sorting and garbage collection.
This is the only way to achieve sorting of garbage. To encourage environmental protection is stupid. People are accustomed only to consuming resources. Therefore, it is necessary to develop stimulation measures.
