This article/study seems like FUD that was written squarely by the plastics industry. I think the lesson here is to use better bottle caps.
It is a public administrative body reporting to the Ministries of Health, the Environment, Agriculture, and Labour.
Regardless, the headline seems to be literally accurate. Microplastics are indeed found in larger quantities in glass-bottled drinks than in plastic-bottled drinks. Those microplastics in glass-bottled drinks come from the paint on the designed-for-glass-bottles bottle cap.
