Polyurethane waste is filling up landfills, but scientists recently had a possible solution: They developed a way to degrade polyuretha.
"Millions of tons of polyurethane are produced every day worldwide for use in foam, plastics, sneakers, insulation and other products," said Ephraim Morado, a doctoral student who presented the research at the conference, "but people typically throw away these when they're done using th.
Of course, Morado isn't the only scientist looking for ways to reuse polyme.
The key difference between regular urethane and Morado's urethane is that Morado's urethane has hydroxyacetal added as one of the monome.
Morado has invented a new type of acetal that can be incorporated into unconventional polyurethan.
Morado has also invented other acetal-containing polyurethanes that trigger degradation when exposed to lig.
In addition, the team is working on how the polyurethane degrades under milder conditions (reaction with vinega.
