>>11264595That computer or smartphone you're posting on right now? It can't be effectively recycled.
Got anything made of carbon fiber composite? It can't be recycled either.
Most plastics can't be effectively recycled, not for less than the cost of producing new plastic instead.
We'd have to go back to everything being made of metal or glass, or maybe wood. Those, really, are the only materials that can be effectively recycled.
Take for example a car tire. Can't be recycled at all. You can't separate out the materials it's made from effectively enough to do anything with it, not unless you're willing to spend several times what it cost to produce to do it. No company is going to be bothered.
In the end if you want to 'recycle' everything 100%, then we have to scale back our entire civilization to the point where we're basically back to being agrarian/subsistence farming, and everything we have and use are made from natural materials and are simple things. Essentially, living in Amish World. No high-tech anything.
The only other way out of it is to go at least as far in the opposite direction: energy/matter conversion technology, or some sort of synthesis technology that allows us to construct/deconstruct objects an atom at a time. Think Star Trek 24th century federation replicator technology, or the future envisioned by Neal Stephenson in 'The Diamond Age'.
