They have been filming funerals at Respect Green Burials site at Laughton.
The company also has a burial site at Scrooby, near Bawtry.
Three one-hour programmes are scheduled to be shown this autumn.
Respect owner Gordon Tulley said: “It is good timing because people are wanting now to have more involvement in arrangements for funerals and to have the time to do it.”
“There is a dissatisfaction with having a standard black funeral, people want to get back to the old way and put something together that’s meaningful for them.”
The TV crews filmed the funeral of a man whose coffin, featuring a picture of a wild flower meadow, was carried by pony and cart to the burial. Family and friends wrote farewell messages and doves were released as a final send-off.
They also interviewed a woman with a life-limiting illness who is planning a living wake.
