Every year, New Zealand produces about 50,000 tonnes of chicken feathers. In the past the only options for these feathers were to process them into low-grade animal feed, incinerate them or store them in landfills. But the feathers are now being sought as extra support for biodegradable plastics. An example of this concept was announced in March 2011, when American scientists including Dr Yiqi Yang demonstrated that they could make chicken-feather-based thermoplastics which remained stable in water. A little over a year later, at the University of Waikato, a similar incident is occurring. [ + ]
