The technique uses a low-toxicity “catalyst” to dissolve the plastic molecules through exposure to sunlight, said Assistant Professor Soo Han Sen, who led a team of five scientists on the project.
At a press conference on Wednesday (Dec 11), Asst Prof Soo said the process resulted in formic acid – a highly versatile natural chemical that can be used as a food preservative, antibacterial cleaning agent or in fuel cells for hydrogen energy.
“The market for formic acid is millions of tonnes every year,” said the chemist from NTU’s School of Physical and Mathematical Sciences.
