Wisconsin senators approved a bill earlier this week allowing dead bodies to be dissolved in a chemical bath and disposed like sewage. The bill, Senate Bill 228, authorizes a practice called alkaline hydrolysis, or “water cremation,” which liquifies the human body using a mixture of water, heat, and chemical agents, leaving only bones behind. The liquid is then dumped into the sewage system or boiled off, and bones can be crushed and deposited in an urn. The Republican-led Senate passed the legislation without debate on Tuesday over the objection of the Catholic bishops of Wisconsin.
