Instead of hauling out the backhoe or firing up an incinerator to dispose of human remains, funeral directors could offer a method called alkaline hydrolysis or “bio-cremation.” This technique uses hot water, pressure, and potassium-sulfate (the strongly basic chemical often referred to as lye) to break down the body’s tissues into simple molecules in a matter of a few hours. Proponents of bio-cremation say it’s the eco-friendly death option.
