Tiny Trash Factories

摘要

NOT ALL WASTE HAS TO GO TO WASTE. Most of the world's 2.22 billion tons of annual trash ends up in landfills or open dumps. Veena Sahajwalla, a materials scientist and engineer at the University of New South Wales in Sydney, Australia, has created a solution to our massive trash problem: waste microfactories. These little trash processors - some as small as 500 square feet - house a series of machines that recycle waste and transform it into new materials with thermal technology. The new all-in-one approach could leave our current recycling processes in the dust.
