Just don't toss it in the recycling bin

  Ugh. It’s hard to accept that the likes of this stuff (sludge) is going on the ground that grows my food.

But what are the alternatives? If we want to be — must be — a sustainable society, we have to do something with our waste besides bury it or throw it in the ocean. What else can we do with it? Process it for biofuel, perhaps. Recover the valuable chemicals and heavy metals for reuse? I hope someone with some know-how and resources is thinking about it.
