What materials are prohibited from being included in a cremation?

The prohibition of certain materials during the cremation process is primarily to ensure safety, efficiency, and environmental compliance. Non-combustibles and hazardous waste fall under strict regulations due to the potential risks they pose. Non-combustibles, like metals or any items that do not burn, can cause damage to cremation equipment and may interfere with the process, while hazardous waste can release toxic substances into the environment when cremated.

The cremation process requires careful consideration of what can be safely and effectively burned, which is why specific categories of materials are banned. Items that could potentially create harmful emissions or are difficult to manage during cremation are not allowed to ensure the safety of the facility and adherence to environmental standards.

Other options such as biodegradable materials are acceptable for cremation, as they do not pose similar risks. Similarly, non-metallic items might include many acceptable materials, and sentimental items can often be incorporated unless they fall into a prohibited category. Thus, the emphasis is strictly on avoiding any hazards or complications during the process, which is why the inclusion of non-combustibles and hazardous waste is the correct focus for prohibited items in cremation.
