What is the main reason to modify operational instructions when cremating larger bodies?

Modifying operational instructions when cremating larger bodies primarily aims to avoid emissions problems. Larger bodies require specific adjustments in the cremation process to ensure that the combustion is complete and efficient. This is particularly important because larger mass can lead to incomplete combustion, which may produce more smoke, particulates, and potentially harmful emissions if not properly managed.

The combustion process generates gases and particulates, and failure to adequately manage these for larger bodies can lead to environmental and regulatory compliance issues. This necessitates adaptations such as adjusting the fuel supply, temperature, and air flow within the cremation unit to ensure that the emissions stay within legal limits and meet health and environmental standards.

While reducing cremation time may seem relevant, the primary focus is on effectively managing the emissions produced during the process. Similarly, enhancing the appearance of ashes or fulfilling family requests does not directly address the technical requirements and environmental considerations that arise from cremating larger bodies.
