ASHES TO ASHES – DUST TO RECYCLING The small Danish company Afatek has a world record in recovering valuable metals and minerals from ashes. Ramboll helped make the process even more efficient. By Michael Rothenborg
irector Jens Kallesøe from Afatek grabs a ballpoint pen and starts to dismantle it. “This ordinary ballpoint pen contains four different materials: On the outside is a belly belt and a clip, both made of stainless steel. Two pieces of plastic tubing hold it all together. Inside is an ink tube made of plastic. One end has a stainless steel spring, and the other a small brass piece, where the ink comes out. So we found two types of plastic and two types of metal with sizes down to 1 mm,” he says, now with four different pen pieces in his hands.
