Alkaline hydrolysis and respect for the dead: an ethical critique.

Alkaline hydrolysis is an increasingly popular method of disposing of human corpses, which involves dissolving them into a solution of 95% water and 5% alkali, producing some bone residue and a liquid waste that can be flushed into the sewer system or otherwise hygienically disposed of. Favoured particularly by environmentalists for its perceived ecological advantages over traditional methods of inhumation and cremation, alkaline hydrolysis has been charged by some critics with being insufficiently respectful of the human corpse, and by implication the living human being whose body it once was. Following a discussion of the idea of respect for the dead and its cultural variability, it is argued that alkaline hydrolysis breaches no fundamental principles of respect for the deceased or their remains and that worries on this score are based on misunderstanding or prejudice. The question is raised whether alkaline hydrolysis might nevertheless be considered less respectful to the dead than traditional methods of burial and cremation. Three <italic>prima facie</italic> reasons in support of this claim are weighed and rejected. It is concluded that there are no sound objections based on considerations of human dignity to the adoption of alkaline hydrolysis as a disposal method for human bodies. [ABSTRACT FROM AUTHOR]
