The Process of Cremation

Definition and Explanation

Cremation is the process of reducing a deceased body to its essential elements by exposing it to high temperatures, usually between 1400 and 1800 degrees Fahrenheit, in a specially designed chamber called a cremation retort. During the process, the remains are transformed into ashes and bone fragments, which are then further processed to create fine particles known as cremains. These cremains are typically placed in an urn and returned to the family as a way to memorialize their loved one.

Energy Consumption

Cremation requires a significant amount of energy to achieve the high temperatures necessary for the process. The cremation retort is heated using either natural gas or propane, both of which are fossil fuels. According to research, the energy consumption can vary depending on factors such as the size of the body and the efficiency of the Cremation equipment. On average, a single cremation can consume approximately 28 gallons of fuel, releasing significant amounts of carbon dioxide into the atmosphere during the process.
