Oops, your mistake. Cremated remains still need to be buried.
Did you read the article?
At the local RC cemetery, it's required that cremains be in a RC approved container and the cost of opening and closing a grave for cremains is virtually the same as for a coffin, which is ridiculous. Also, there are headstone foundation and headstone requirements. Naturally, the RC cemetery makes money for all these "required" things.
In fairness to the RC church, it's not required that Roman Catholics be buried in a RC cemetery. However, it is required that any burial meet RC "requirements".
