It boils down to “don’t microwave plastics that aren’t microwave safe” What a fucking revelation
The main plastic the article calls into question is polypropylene. I’ve got bad news for you. Its used frequently in microwavable food products and sold as “microwave safe”. Polypropylene is recycle symbol #5.
Here’s a perfect example. That cup of rice is #5 plastic, polypropylene. You can see the package says right on it “Microwave for one minute”. This isn’t the only product I’ve seen with a polypropylene container. Here’s another one for BBQ pulled porkyou can even see on the package itself in the bottom right hand corner at the recycling symbol it says its polypropylene. And if you look at the preparation instructions it gives microwave directions.
I can’t speak to the science in the article, but it certainly is talking about a plastic that consumers are regularly told is safe to microwave.
