If you're new to the idea of alkaline hydrolysis, here's how it works. A 300°F solution of a strong base, in this case lye (sodium hydroxide), is sprayed on a body at 60 pounds of pressure per square inch in what looks sort of like a body-shaped stainless steel pressure cooker. The base hydrolyzes the tissues, leaving a syrupy brown liquid and some bone residue. The bone residue could be collected and dried, if desired, similar to the collection of cremated remains. In the case of animal carcasses, the solution is washed down the drain. There are two medical centers using the equipment for research cadavers (University of Florida in Gainesville and the Mayo Clinic in Rochester, MN). They flush the remains, too. Although the solution has a strong odor, it is sterile and does not pose a threat to the water supply.
The equipment for alkaline hydrolysis is a little more expensive than what you need for cremation, but the process may be more environmental friendly than cremation, which releases carbon dioxide and mercury from dental amalgams. The sodium hydroxide solution may be less troublesome than the blood and leftover embalming fluid washed down the drain when a body is prepared for burial.
