From Harper’s magazine, November 1998:

Ø       'The true origin of "biosolid" can be traced back to a Name Change Task
> Force created by the sewage industry to improve the image of its main
> product, sludge. In 1990, the task force sponsored a contest to come up
> with a more marketable name. Rejected candidates include "all growth,"
> "purenutri," "biolife," "bioslurp," "black gold," "geoslime,"
> "sca-doo," "the end product," "humanure," "hu-doo," "bioresidue,"
> "urban biomass," "powergro," "organite," and "nutricake." '

Here are the ones I would have submitted:
