The iameco computer, made by the Dublin company MicroPro Computers, is built from biodegradable wood panels manufactured using waste products from the lumber and pulp industry.

They say they can implant the seeds of native-tree species into the wood panels. "One advantage of iameco is that when the components are buried in landfill the wood gets wet, breaks down and new plants begin to grow from old computers," says the Managing Director of MicroPro.
