I’m slightly surprised this hasn’t seen more coverage (as far as I’m aware it’s never been reported outside of the council’s formal meetings) since it’s a fairly innovative way of dealing with household waste – although apparently it’s been used on submarines for years.
Pyrolysis, essentially (and unscientifically) is burning without oxygen so there is no fire. The process creates a dust that can be washed away with waste water through the drains. Remaining items, like glass and metal can be recycled. This has potentially huge environmental benefits, from reducing the number of refuse vehicles on the road, through to minimising the amount of landfill needed.
The two test sites were a success, proving that it is a viable technology but identifying a few problems or issues that need to be resolved. It’s now for the manufacturer, PyroPure, to go away and work up their prototypes into a commercial product.
