The 600 million year old technology beneath our feet | Michael Quintern | TEDxTauranga

How do you process hundreds of truck loads of "muck" and industrial waste and not affect the environment.?

The solution lay in the earth itself. Earthworms eat their body weight a day, they can double their population within two months, and compress waste into 80% of what it was. If they were pretty they’d be everyone’s favourite creature. Michael owns and operates NZ's largest farm of 1,700,000,000 earthworms to turn industrial sludge into organic, fertiliser. He is a soil scientist who found himself employed to solve the problem of industrial waste and the baren lands left behind by forest harvesting. This is the story of turning muck into gold.

Excellent lecture and approach! I wonder how the muck is deposited to the wormed disposal site so that it is easily aquired by the worms and worms are not killed during the disposal process. You need dump it into a huge pile which then takes a long time for worms to enter/reproduce/process evenly? Also what holding pit/field design is used to contain the smelly muck?
I picture a huge field with huge tanker trucks with hoses to spray the muck onto new areas constantly and repeating in layers giving time for some planted/deposited worms to reproduce/spread throughout. I see worms drowned after rain so is this an issue addressed?
