‘Smart Trash’ cash for recycling concept

By - November 2, 2009
If the benefit to our environment isn’t enough to get some people to recycle, Georgia Tech’s Valerie Thomas has come up with the concept of offering a cash incentive enabled by “Smart Trash”. The concept involves a scanner integrated into a trash receptacle that automatically records what is being disposed of using Universal Product Codes (UPC) or radio frequency identification (RFID) tags attached to the trash. This would not only allow recyclers to better sort the waste but could also provide a cash back channel to consumers recycling goods of value. Read More

Magnetic leaves indicate levels of air pollution

By - October 19, 2009 2 Pictures
Measuring the level of magnetism of tree leaves could be a powerful tool to monitor the air quality of streets. A new study has shown that leaves along bus routes were up to ten times more magnetic than leaves on quieter streets. The magnetism comes from tiny particles of pollution, such as iron oxides from diesel exhaust, that float through the air and either stick to the leaves, or grow right into them. Read More
