Electric cremation is a modern alternative to traditional gas-fired cremation. Instead of burning fossil fuels (usually natural gas or propane), an electric cremator uses electric heating elements to create the high, even temperatures needed for cremation.

Because there is no open flame or on-site fuel combustion, electric cremation can dramatically reduce carbon footprint and greenhouse gas emissions compared with gas cremators, particularly when powered by a low-carbon or renewable electricity grid. Recent analyses indicate that electric cremators can reduce CO₂ emissions by approximately 50–80%, and in some designs up to 90%, compared with traditional gas units.

While every manufacturer is different, most electric cremators follow the same basic steps:

1. Preheating the chamber

High-temperature refractory bricks line the cremation chamber. Electric heating elements embedded around the chamber keep it at operating temperature. EverGreene’s system operates as “hot hearth,” staying warm between cremations to improve efficiency and shorten cycle times.

2. Placing the pet

The pet is placed in the cremation chamber on a refractory tray or hearth. In some pet cremation units such as ours, the chamber has separate doorways and a partition so that dual cremations can be completed while keeping remains physically separated further reducing energy use.

3. Controlled electric heating

• Electric elements supply steady, even heat without flame or burner roar.
• Sensors and a PLC (programmable logic controller) constantly monitor chamber temperature, time, and oxygen levels for optimal combustion of organic material. The state-of-the-art cremators use PLC-based touchscreen controls that automate cycle timing and log cycle data (temperatures, durations, alarms) for quality control and energy optimization.
• Because of improved efficiency, electric cremators generally operate at lower temperatures than standards cremators.
• The average electricity use per cremation decreases as the unit is used more consistently.
  

4. Emission handling

Gases generated during the cremation process are routed to a secondary chamber for additional thermal treatment to reduce particulate matter and odor. Following secondary treatment, emissions discharged to the atmosphere are composed primarily of water vapor and carbon dioxide, with only trace amounts of naturally occurring gases.

5. Processing the remains

Once the cremation cycle is complete, the subsequent steps follow the same careful process as traditional cremation. The remains are allowed to cool before being processed into a fine, sand-like powder, which is then placed into an urn container for the family.

*The cremated remains produced by this method are identical in appearance and composition to those from traditional flame-based systems but achieved through an improved environmental performance.

Electric cremators typically include:

Electric heating elements

High-output resistive elements provide controllable, even heat. There are no gas lines or burners.

Refractory-lined chamber

Thick refractory bricks retain heat, improving efficiency and protecting the metal shell of the unit. Load capacities and throughputs vary by model—many pet systems are designed for individual or small-batch loads with capacities up to a few hundred kilograms.

Automated digital controls (PLC / touch screen)

Modern pet cremators use PLC-based touch-screen controls that automate warm-up, cycle timing, and cooldown, and can log cycle data (temperatures, durations, alarms) for quality control and energy optimization.

Energy use

Per manufacturer specifications, our cremator will use 100 to 125 kWh per an 8-hour operating day. This is similar energy use as charging a single electric vehicle 1 to 1.5 times daily. When paired with renewable electricity such as solar panels, overall climate impact can be significantly reduced.

Because the system draws from the electrical grid, facilities may utilize renewable energy sources to operate with dramatically lower greenhouse gas output. Many countries already recognize electric cremation as a future-standard approach for compliance and sustainability leadership.

For clients who value an eco-conscious legacy for their pets, electric cremation stands apart.

Electric cremation offers a flameless, low-emission alternative to gas cremation that does not involve water or chemicals and can be powered by renewable electricity—often making it the most practical “green” method for many crematories today. This is cremation rethought for modern expectations.
