composting is encouraged and even mandatory for office buildings in san francisco

If it came from the earth, return it to the earth.

I also have a hypothesis that composting saves 'compressible' material from settling in landfills.. and... since san francisco is mostly built on landfill, well, we don't need any more settling.

do eeiiiit.  you'll feel better about yourself, and the planet we all share --
