What's There Already Worth Billions
Thanks to rising oil prices, the value of all that plastic we've already absent-mindedly thrown into our landfills is really worth something. In Britain alone the landfills contain some 200 million tonnes of discarded plastic, which could be worth £60 billion ($111 billion) if recovered and recycled.
Chris Dow of Closed Loop London described the situation to Reuters,

But the insane thing is that we are talking now about investing millions into tapping into a resource under the ground, when the real tragedy is that every week we’re still dumping tonnes and tonnes of plastic into more landfills. It’s an act of vandalism against the environment.
