Some areas are at least trying... Our local county just instituted curbside recycling; one container takes paper, cardboard, glass, plastic containers, etc.
Easy to do, no separating.
Reduces the amount of "garbage" trash by about half.
Years ago, I saw plans for a method to not only get rid of garbage but to produce fuel. Essentially, you dig a big hole and put in a plastic liner. Garbage goes in, methane gas comes out to be burned as fuel. When the pit finally fills with solid waste that won't break down further, it's essentially stable and can just be covered over.
