Re: [GreenYes] energy (and other) savings through recycling
Please excuse a lurker, but I felt I had to respond to part of this.

This is NOT recycling. This is burning waste for fuel.

There are many concerns about these ideas, and we have a long way to go before
waste-to-energy become a safe and feasible idea.

For example, landfill gas is not just methane, and it's not the equivalent of
natural gas (which is not just methane either). Landfill gas may contain
highly variable amounts of all sorts of unknown and unpredictable gasses and
volatiles. This makes it very hard to design a clean and efficient burner.

Some folks say buring tires for fuel in specially designede burners may work
well, others say tires contain chlorinated organics, which makes burning them
highly problematic.

And I'm not sure what is meant by using wood chips, forestry  and ag waste to
fuel biomass plants. Does this mean burning the stuff (sounds inefficient), or
deriving other forms of fuel (methane, ethanol, etc.) and burning that?

Please don't trade one problem for another.
