Alkaline Hydrolysis Legal States 2026

Alkaline hydrolysis is an alternative method of disposing of human and pet remains. It has become an alternative to traditional burial and cremation. This is a cremation method that uses lye and heat to dispose of the body. It is based on the principle of alkaline hydrolysis.

Using this method, the body is placed in a vessel that has a tremendous amount of pressure. Then, it is heated to a temperature of about 160 degrees C, or 320 F, at that high pressure. The goal of the pressure is to prevent the body from boiling. The entire process takes between four and six hours to complete. If the temperature is reduced, the process will take a few extra hours. The more fat there is, the longer the process will take.

Legal Status of Alkaline Hydrolysis by State

Alkaline hydrolysis is legally recognized in 29 U.S. states. However, in five of those states—Idaho, Kansas, Maryland, Vermont, and Wyoming—the process is legal but not currently available through licensed funeral providers.

In 22 states and the District of Columbia, no legislation or regulations currently address alkaline hydrolysis. New Hampshire is the only state where the practice is explicitly illegal. Because funeral and disposition laws are regulated at the state level, availability and regulatory clarity vary quite a bit across the country.

States Where Alkaline Hydrolysis Is Legal but Not Available

In five states—Idaho, Kansas, Maryland, Vermont, and Wyoming—alkaline hydrolysis is legally permitted but is not offered by licensed funeral homes or cremation providers. In these states, statutes or regulatory definitions allow the practice, but no facilities have implemented the equipment or obtained the necessary approvals to perform it.

This is an important difference between legal recognition and practical availability – even where authorized by law, alkaline hydrolysis may require specialized equipment, regulatory approval, and consumer demand before services become operational.

Religious and Cultural Considerations around Alkaline Hydrolysis

As with traditional cremation, alkaline hydrolysis is viewed differently across religious and cultural communities. Some religious traditions discourage any form of cremation or non-burial disposition, while others respect individual preference.

Because funeral practices often reflect deeply held beliefs, individuals considering alkaline hydrolysis may wish to consult religious leaders, family members, or cultural authorities before making a final decision.
