AI Technical Summary

Technical Problem

Existing methods for tissue dissolution, such as alkaline hydrolysis, result in significant residual waste and require extensive treatment facilities due to high biological oxygen demand, with incomplete dissolution times exceeding 18-24 hours.

Method used

The use of ethanolic potassium hydroxide solutions at controlled temperatures (155-200°F) significantly reduces dissolution time to approximately two hours, followed by neutralization with nitric acid to form a crystalline material suitable for direct disposal, reducing biological oxygen demand and facilitating soil application.

Benefits of technology

The method achieves rapid tissue dissolution with minimal residual waste, enabling efficient disposal and potential soil application of the resulting products, thus reducing the need for extensive waste treatment facilities.

Abstract

Methods forth chemical dissolution of human and other cadavers, such as pets as an example, using ethanolic potassium hydroxide (KOH) or ethanol-water solutions of KOH at atmospheric pressure are described. After acid neutralization, to a neutral pH range, the resulting solutions may be applied to the earth for disposal as fertilizer, or further treated using hydrogen peroxide. Use of ethanol has been found to reduce the dissolution time of the cadavers to approximately two hours for high concentrations of KOH.
