What is the status of plastic and fiberglass caskets regarding cremation?

Plastic and fiberglass caskets are considered not suitable for cremation due to the materials they are made from. Unlike traditional wooden or cardboard caskets, which can burn completely and leave minimal residual material, plastic and fiberglass can emit harmful toxins when heated during the cremation process. This can not only damage the crematory equipment but also potentially harm the environment. The emissions from burning these materials can result in pollution or safety hazards for the personnel operating the cremation facility. Therefore, many crematories have policies in place that require plastic and fiberglass caskets to be refused for cremation to maintain operational safety and adherence to environmental regulations.

In contrast, some alternatives may be acceptable depending on specific guidelines set by individual crematories, but these generally involve natural or biodegradable materials that pose fewer environmental concerns.
