Greenpeace Philippines’ Zero Waste Campaigner Marian Ledesma said those microwaveable containers emit particles that humans can inhale, aside from the environmental effects.

“Sinasabihan tayo na huwag i-microwave yung mga plastic dahil it can lead to harmful effect. And a lot of doctors still say na kahit microwaveable yung plastic, huwag pa ring gamitin, i-transfer sa mga ceramic or glass na container. Because high heat does have an effect on plastic and a tendency to release it,” Ledesma said.
