Are reusable plastic cups safe?
Reusable” cups aren’t necessarily much better when it comes to leaching, as they are often made of plastic; heat and wear accelerates leaching, and acidic drinks like coffee absorb chemicals more easily. Overall, drinking from plastic containers can have negative health effects due to the leaching of harmful chemicals. To minimize risks, opt for safer alternatives like glass or stainless steel.Disposable cups, lids, and straws are major contributors to plastic waste, causing detrimental effects on marine life and ecosystems.
