The only exception would be if it was the expressed wish of the deceased not to be cremated. The crematoria will also stipulate certain types of coffins can only be used. Many crematoria now accept cardboard, bamboo, and wicker coffins and we will guide you on those acceptable. Cremators burn a great deal of energy and are bound by legislation on very strict emission controls which will also mean certain materials cannot be placed within the coffin. We will discuss any concerns you may have with this.
