Unnatural resources (mining landfills)
Sarah Barmak, The Star (Canada)
Even as the price of commodities falls, landfill mining is becoming both more viable and increasingly sophisticated. Is the idea of trash-as-resource finally about to reach its tipping point?
Something curious is happening to one of the landfills used by the city of Rawalpindi, Pakistan. Filled with the refuse from a city of 750,000 over the past 20-odd years – plastic, old tires, food waste, and sand and stones swept from the city streets – the dump covers 1.5 square kilometres.

Mark Langan, The Guardian
We've seen the intricate cars, engines, bicycles and other machinations of civilization created out of cardboard by artist Chris Gilmour: bafflingly accurate and detailed for the imprecise medium. Artist Mark Langan, in contrast, creates sculptural works that are inspired by the form of cardboard itself, celebrating its grooves and textures. This work demands a kind of respect and awe for its material, which the artist collects from his own neighborhood...
