Which method is a final disposition option in Oregon that uses water-based chemical dissolution?

• A. Burial
• B. Cremation
• C. Alkaline hydrolysis
• D. Natural Organic Reduction

Answer: (C)

Alkaline hydrolysis is a final disposition option that uses water-based chemical dissolution. In a specialized vessel, the body is combined with water and an alkaline agent (such as potassium or sodium hydroxide) and heated under controlled conditions to accelerate decomposition, producing a sterile liquid effluent and mineral bone fragments. The bone is processed into a powder for return to the family, similar to cremated remains, while the liquid effluent is treated before disposal according to regulatory standards. This method is often highlighted for its lower energy use and reduced emissions compared with flame-based cremation, making it a more environmentally friendly option. In Oregon, this process is available as a final disposition choice alongside traditional burial and cremation. Traditional burial involves placing the body in the ground, cremation uses combustion, and natural organic reduction uses composting-like natural processes in soil, not water-based chemical dissolution.
