What reasoning do you have for avoiding plastic?
BPA and BPS, I guess.
- TheDong 4y agoYou're brewing coffee at <100°C, and all the plastic coffee brewers I've used have been BPA+BPS free (i.e. polypropylene) Is there still any known issue? If they meant BPA, surely they could just say that?
- schiffern 4y agoNot sure about polypropylene, but both nylon and PET are known to shed billions of micro/nano-plastic particles into 95 °C water. https://pubs.acs.org/doi/10.1021/acs.est.9b02540 https://pubs.acs.org/doi/10.1021/acs.est.9b02540 Note they studied mesh bags. Flat surfaces with less exposed area should have lower emission rates. Still not great. Edit: apparently polypropylene does too. https://www.theguardian.com/environment/2020/oct/19/bottle-fed-babies-swallow-millions-microplastics-day-study https://www.theguardian.com/environment/2020/oct/19/bottle-f...
