Collection and processing will use up more fuel than can be produced.

I've always wondered how much recycling programs actually save what with the
big, diesel burning trucks they use to collect everything.

   I think you may be missing the point.  The collection of vegetation
typically happens indepedently of any recycling activity.  What the
cecycling does in reduce landfill requirements, and "hopefully" returns
nutrients and biomass to the ecosystem.  My county has a huge mulching
program, which digests this stuff and outputs something that looks like rich
soil.

Not really. I was addressing Frank's "Collection and processing will use up
more fuel than can be produced." line.


Valid points. Personally I spread my lawn clippings on the garden or feed
them to my cattle (NO lawn chemicals).
