Current recycling is far from optimal. A company could exploit this and raise recycling to a whole new standard.

Its raw material costs would be zero or very low, its logistics costs would be high, but by using technology and automation it could definitely become (very) profitable.

And to take on the task of retransforming, by extensive chemical engineering, all the discarded products into vanilla raw material, and to exploit the non-renewable rest as a source of energy for the whole system by burning it.

Any other ideas, guys ?
