Extract from The Telegraph Online:
"Devised by Graham Wiles of the Green Business Network, the ABLE Project, based in Wakefield, near Leeds, began by involving disadvantaged people in cardboard recycling. What it evolved into, however, is a system that mirrors a natural process: the "circle of life", in which each living thing, or its waste, provides the food for another.
"First, the young people involved started shredding the discarded paper and selling it as bedding for horses. Wiles then had the idea of collecting the soiled bedding and composting it in a wormery. He established a fish farm to raise Siberian sturgeon and ornamental Koi carp, feeding them on the worms. This year, the sturgeon produced their first batch of caviar.
"The chain doesn't end there. Wiles has now planted willow trees, fed on composted sludge from the local sewage works, which will be used to fuel a biomass boiler, to provide the optimal growing temperature for the fish. The waste from the fish tanks will then fertilise an orchard, tree nursery and vegetable plot. As Pawlyn explains, the ABLE Project "demonstrates the potential to turn a waste material into a high value product while yielding numerous social, economic and environmental benefits."
