Pet aquamation, also called water cremation or alkaline hydrolysis, is a modern and environmentally friendly method of final care. It uses a gentle warm water bath and alkali salt to break down organic material, mimicking natural decomposition but in a fraction of the time.

Unlike traditional flame cremation, aquamation uses water instead of fire. This process is:

• Eco-friendly: It uses 90% less energy and produces no harmful emissions.

• Gentle and respectful: Your pet’s remains are handled with the utmost care.

• Cleaner: The resulting ashes are pure and free of carbon residue.

Yes! Aquamation is one of the most sustainable aftercare options. The process does not produce any greenhouse gases and leaves behind a nutrient-rich liquid that is safely returned to the environment. It significantly reduces your pet's carbon pawprint compared to other aftercare methods.

After the aquamation process, we dry and finely process the remaining bone material into soft, white ashes. For individual cremations, these ashes are returned to you in an urn of your choice. For group cremations, the ashes are respectfully scattered on a private property in the mountains of Conifer, Colorado.

At Green Heart, we prioritize respectful, personalized care for every pet, which takes time. The aquamation process is slow and gentle, typically taking 24-36 hours to complete. Afterwards, the cremation ash is allowed to air dry for a few days before being respectfully placed into the urn of your choice. Your pet's ashes are usually ready to go home within 7-10 days.

Absolutely. We offer a range of memorial keepsakes including clay paw prints, framed ink paw and nose prints, resin fur hearts, memorial pendants and keychains, and memorial stones.

We serve pets of all sizes, including dogs, cats, rabbits, ferrets, hamsters, birds, reptiles, and other small animals. Because aquamation is so gentle, it is the preferred method of cremation for small pocket pets. Most animals up to 250 pounds can be safely and respectfully cremated at Green Heart.

Both flame cremation and burial can carry negative environmental impacts. Flame cremation releases greenhouse gases and mercury emissions, while traditional burial may introduce chemicals into the soil and groundwater which can harm the environment and wildlife.

Aquamation offers a gentler, greener alternative. It’s the perfect choice if you’re looking for:

• Environmentally friendly aftercare – Aquamation uses 90% less energy than flame cremation and produces no harmful air emissions.

• A gentle and natural process – This water-based method mirrors the way the body naturally returns to the earth, without flames or smoke.

• A positive impact on the planet – By choosing aquamation, you honor your pet’s memory while also making a sustainable choice for future generations.

For many families, water cremation feels like a loving way to say goodbye that reflects the same care and respect they gave their pet in life.

We understand this is a deeply personal decision and that every family's journey with loss is unique. Aquamation is ideal if you value sustainability and want to give your pet a respectful, eco-friendly farewell. Our compassionate team is here to guide you through the process and answer any questions you may have.
