Human Waste Project was an American alternative metal band from Huntington Beach, California. It was formed in December 1993 by bassist Jeff Schartoff and guitarist Roman Marisak, and after going through several shifts in personnel, the band's lineup solidified in 1994 with Schartoff, drummer Scott Ellis, vocalist Aimee Echo and guitarist Mike Tempesta.

Human Waste Project signed with Hollywood Records in June 1996, and released their debut (and only) album, E-lux, in September 1997. Although poor promotion of the album prevented it from becoming a commercial success, it received warm reviews from critics, and relentless touring and strong support from Kerrang! magazine helped Human Waste Project cultivate a cult following in the United Kingdom. The band also managed to make an appearance on second stage of Ozzfest UK in June 1998, after being dropped by Hollywood two months prior.

Shortly after the band's performance at Ozzfest, Aimee Echo quit Human Waste Project due to creative differences, and the band played its final show in July 1998. Between 2008 and 2009, the members of Human Waste Project had a few partial reunions, although the band never formally reformed.
