Big Bertha is hot and loud: the giant green machine emits bangs and mighty shudders as it grinds up a pile of broken electrical goods. The oversized blender, which can reduce up to 100 fridges an hour to tiny pieces, is a key part of online electrical goods retailer AO World’s plan to turn old appliances into new items for sale, and deal with part of UK’s hefty pile of unwanted electrical waste.
Boss John Roberts grins as he inspects the works. He’s wearing trainers and a belt bearing the company’s logo – in the same bright green as Bertha and most of the rest of the building’s machinery.
