[USCC] Landfill

Hello Myron, There are digesters on the market and operational in Europe
that semi-digest the waste material, remove the methane and put the
semi-digested material out for final digestion into stable compost. The
drawback of these units is their cost of around $ 20,000,000. and the
undying dream of cheap places to hide waste.
My concern of adding anything to landfill is not a slight reduction in
available material for composting but the increase in the volume of toxic
leachates that run everyday, for who knows how long, from every landfill.
Although our company has been very sucessful in treating this leachate it is
an expensive and complex arrangement.
As many of us embraced composting as part of a wholelistic solution to no
more landfills in the future, I think a few pennies of poor quality dirty
methane will soon run its coarse in the history of dumb ideas.
