A team led by Dr. Avraam Isayev, Professor of Polymer Engineering at University of Akron, Ohio has developed a technique called 『ultrasonic devulcanization.』 It allows for no longer used rubber to be reprocessed, which was virtually impossible to do before.

This significant discovery was the recipient of 2011 Advanced Materials Innovation Award by NorTech, a USA non-profit technology centered development organization.

Congratulations, Dr. Avraam Isayev and colleagues, on your green invention and award.
May more such Earth-loving creations benefit all beings on our shared planet.
