'''Biosolids''' is the name preferred by the lobby association for U.S. sewage treatment plants, the [[Water Environment Federation]] (WEF), for [[sewage sludge]], a word chosen through an Orwellian PR contest. (See: [[You say biosolids, I say sewage sludge]].)
The WEF, with the support of the [[Environmental Protection Agency]], turned to the disposal of sewage sludge on land after the imposition of bans on ocean disposal and incineration.
