Flushing the Dead down the toilet

From the brave new world

THE EU is studying proposals from Belgian undertakers to dissolve corpses in caustic solutions.

The departed could then be flushed into the sewage systems of towns and cities to be recycled at water processing plants.

Can you guess what the motivation behind this new body disposal method is?

Here's a hint

Known as resomation, the process significantly reduces the 260 kilograms of carbon dioxide that the burning of a body spews into the air.
