What type of container is not considered an alternative container for cremation?

In the context of cremation, an alternative container is designed to hold human remains for cremation and must meet specific criteria. A sealed metal casket with a lining is not considered an alternative container because it does not fulfill the requirements for cremation practices. Metal caskets are typically intended for burial rather than cremation, as they are durable and often lack the necessary combustibility needed for the cremation process.

On the other hand, materials that are readily combustible and designed specifically for the purpose of cremation—such as cardboard boxes, disposable containers made from wood, or other rigid containers made from combustible materials—qualify as alternative containers. These options allow for the safe and efficient cremation of remains while adhering to industry standards and regulations.
