Involvement in the Toxic Sludge Industry

Casella is engaged in the production and marketing of toxic sludge, the euphemistic PR term for which is "biosolids."

A list of just some of the hazardous chemicals and pathogens found in sludge can be found in the article Sludge contaminants. Sludge contaminants include Dioxins and Furans, Flame Retardants, Metals, Organochlorine Pesticides, 1,2-Dibromo-3-Chloropropane (DBCP), Naphthalene, Triclosan, Nonylphenols, Phthalates, Nanosilver, and thousands more substances. "Sewage is the mix of water and whatever wastes from domestic and industrial life are flushed into the sewer. ... We must note that, though the aim of sewage treatment is to produce clean water, it is never to produce 'clean' sludge. Indeed, the 'dirtier' the sludge - the more complete its concentration of the noxious wastes - the more the treatment has done its job. ... very waste produced in our society that can be got rid of down toilets and drains and that can also be got out of the sewage by a given treatment process will be in the sludge. Sludge is thus inevitably a noxious brew of vastly various and incompatible materials unpredictable in themselves and in the toxicity of their amalgamation, incalculably but certainly wildly dangerous to life."
