There were more than 100 innovative and diverse entries in this year’s competition, but ultimately one winner and runner-up stood out from the rest.
The winning solution proposed using recycled CRT glass as a component for vitrification of nuclear waste. Vitrification involves the melting of nuclear waste materials with glass-forming additives so that the final vitreous product incorporates the waste contaminants. There are significant volumes of nuclear waste currently planned to be vitrified, especially in the U.S. Dr.
The runner-up proposed a two-step solution: (1) conducting an extensive literature review on manufacturing processes for using CRT-related waste glass, including cost analysis (raw materials transport) and the impact on the environment; and, (2) creating an approach for developing a property/composition model for using CRT glass waste forms to treat nuclear wastes, by making chemical durable borosilicate glasses geologically stable. Dr.
“These award-winning ideas are the latest step in determining how to responsibly recycle billions of pounds of lead-heavy CRT glass as consumers switch from CRT electronics to liquid crystal, light-emitting diode (LED) and plasma displays,” said
“The innovative solutions provided by the CRT Challenge present a great opportunity to expand and develop new markets for recycled CRT glass and help recyclers as the industry transitions from CRTs to newer display technologies,” said
