"Worm food for thought"

This episode concerns the use of earthworms to recycle organic waste into fertiliser, a process known as vermiculture. Is this ingenius or what? Sunburst Biotechnologies takes in over 90,000 tonnes of waste a year and produces 45,000 tonnes of certified high-grade fertiliser known as vermicast... which is basically worm excreta (poo!), and according to David Ellery fruits and veggies grown using vermicast is much more juicier!
90,000 tonnes is a lot alright, but that equals just over a week of waste Hong Kong produces.
