Dumping sewage onto landfill trash sounds like a bad idea; one would think that combining the two waste streams would produce something even worse. Not so, says Viridis Waste Control LLC. They have developed a process that turns this unlikely combination into a green solution.
It turns out that you can make landfill garbage biodegrade more quickly when you over it with septage (the material that is pumped out of septic tanks… let’s not be any more specific). Faster garbage biodegradation means a longer lifetime for the landfill, which saves land which would otherwise be lost to landfill use.
This is also a better use for septage, which is often applied to agricultural fields. This can lead to contamination of crops, livestock, and the water table. The septage may also accelerate methane production, which is a benefit if the landfill is set up to capture landfill gases for power production.
Looks like sometimes two negatives really do make a positive.

But the overall scheme makes some sense (based on my trips to the dump).
Lots of nitrogen from the sludge, carbon from the dump, and happy microbes eating away. The mark of a good compost pile.

Compostables such as yard trimmings and food scraps (and food soiled papers) should be diverted from the waste stream and composted.
And, of course, bottles, can, and paper should be diverted for recycling.

To other people on here, your complaints can be put down with "DER" I doudt anyone is saying lets just dump crap alll over our current landfills. everyone knows that landfills leech and pollute, and if this idea were introduced, properly altering landfills to help with gas release and leeching are an OBVIOUS given.
this is how your argument would work against solar:
guy 1: we should buy some solar panels for out house!
guy2: psh, you dont even have a way to connect solar to your house, hippie idiot...
**obviously it will have to be connected, and I doubt guy 1 is proposing just throwing solar panels onto the roof like a lost frisbee...
