I disagree to the statement: "可分解的吸管可能會出問題。因為吸管在還沒喝完就已分解,吸不到了。況且,分解過程還可能在釋放出有毒的化學物質加料到飲料中。"
Current plastic container for the 1 gallon fresh milk in the US is all biodegradable. This container is stable for more than a year when kept in-door. It become fragile under the sun. Because a chemical double bond linking monomers can be broken by the Ultra-violet light from the sun. It also can be broken by the microbe in soil. There is no risk that the straw made with biodegradable plastics would break in use. 作者: 洛28 時間: 2018-12-23 01:32 PM
