Cremation is the process of using extreme heat to break down the body. Your loved one would be placed into a retort or crematorium chamber in a casket or cremation container. A controlled chamber is typically between 1800 to 2000 degrees Fahrenheit during the cremation process but can get as warm as 2500 degrees Fahrenheit+.
The chamber is constructed of a metal exterior, an interior concrete floor, wall comprised of a hard brick near the base and a soft brick near the top. The hard brick provides durable lower walls while the soft brick will retain the heat through out the process. The chamber is designed to contain the intense heat and control the process.
Family members can be present during the start of the cremation process. They can assist the Crematorium Operator in placing their loved one in the retort and have the option of pressing the button that begins the process.
The entire process can take anywhere from 2 to 6 hours, depending on several factors such as;
– The Casket
– The heat of the chamber before the cremation starts
– The individuals bone density and size
Following the cremation process in the chamber, your loved one is brought to a processing station. It is here where any metals, such as screws from the casket, will be magnetically removed. Following this they are mechanically processed and placed in their urn.
Alkaline hydrolysis, sometimes referred to as Water Cremation, takes place in a chamber similar to a crematorium retort. The chamber for Alkaline hydrolysis is a metal air and watertight chamber. Your loved one would be placed in the chamber without a casket. If they are dressed, they must be wearing natural fibers such as wool, leather or silk.
The process uses water, alkaline chemicals, heat, and occasionally pressure and agitation, to accelerate natural decomposition. This takes approximately 2 to 3 hours but can vary depending on several factors such as;
Following this, bone fragments and a neutral liquid called effluent, remain. The effluent is discharged with all other wastewaters. Because the process uses water, the remains are required to dry before being processed further and placed in their urn.
The process results in approximately 32% more cremated remains than flame-based cremation and may require a larger urn.
Early studies show alkaline hydrolysis to be more environmentally friendly. It uses significantly less fuel and has an overall lower carbon footprint than both traditional cremation and burial. Cremation results in carbon dioxide (CO2) emissions that can contribute to greenhouse gases, and earth burial requires a large amount of space and equipment, such as an excavator.
In Canada, Alkaline Hydrolysis is legal in Saskatchewan, The Northwest Territories, Ontario, Quebec, and Newfoundland & Labrador.
