Researchers reveal Volkswagen defeat system that succefully circumvented standard emission testing for at least six years.
Diesel apparently pollutes air much more than what is originally thought. Part of the problem is the defeat devices installed to lower emissions during testing.
Using its original breakthrough tyre recycling technology, Australian startup company Green Distillation Technologies (GDT) ingeniously recycles end-of-life tyres into an oil that when mixed into minute amount of diesel produces high-quality biofuel that cuts emissions without compromising engine performance. GDT also turns old tyres into carbon and steel, leaving nothing wasted. It even uses some of the recovered oil as the heat source.
The Arctic is rapidly changing. Scientists found that sea salt could be contributing to local air pollutants in the Arctic.
A team of students from the University of California, Riverside's Bourns College of Engineering developed an innovative roof tile coating that, when applied to a typical residential roof, can clean the air by breaking down smog-causing nitrogen oxides.
