Mortician here! This is, luckily not true. Recomposition is already legal in several states and they've had massive success with it. The national and state forests that received the recomposted remains are thriving. The only downside (for some people) is that the person who passed cannot be embalmed, and in most states, that means it's illegal to have an open casket visitation to the public. Most states have laws that family can see their loved one without embalming if it's been less than 48 hours after death, but they need liability waivers. The public, however, cannot be a part of an open casket funeral, unless the deceased has been embalmed and sterilized. Closed caskets are fine at any stage. They make hermetically sealing ones that lock in the decomposition smell and keep people safe.
We have a break room, and some people pack food from home?
Morbid fact; if a decedent who has excess weight, gets cremated; the whole building smells like bacon. I remember walking in one day, (at my first job that had a crematory retort inside) and was so excited thinking our boss had bought us breakfast... nope... I gave up bacon for over 2 years.
