  Are we already utilizing the human excreta on large scale? I've seen it at individual level, but I don't know if its being utilized on large scale. It could be a decent source of bio gas that can be used in Electricity generation. We do have the man power here. 😁

  Also read about the water extracting method from fog.
  The large nets are used to trap the fog and extract water from it. It is useful for the drinking and irrigation purpose.

  I haven't seen it personally but read about many biogas plants like:
  Janta biogas plant
  Deen Bandhu biogas plant
  Khadi Village industry commission.

  Waste paper can be used to produce electricity. It's a way recycling waste products into more useful products.(but only at a small scale)
  Sony's bio battery turns waste paper into electricity - BBC News

  E-waste resources can be recycled, not all but monitors & CRTs, keyboards, laptops, modems, telephone boards, hard drives, floppy drives, Compact disks, mobiles, fax machines, printers, CPUs, memory chips, connecting wires & cables can be recycled.
  By recycling PCB, crt, Hg(mercury) etc which are dangerous can be removed, useful metals like copper, lead, gold are reused.

  Especially Pb acid batteries they are best when they are recycled if left unrecycled they become hazardous but if recycled activated Pb a catalyst is readily available for our disposal
