Plastic cups and water bottles

Okay, as some of you have already know this, I'm a member of the Plastic cups committee of the Student Council of American International Middle School in HCM City, Vietnam. My school had thought about buying water bottles to sell in the school, but they turned down that decision and instead, continued using plastic cups. I don't know why the school kept on using plastic cups, since on average, producing ONE single plastic cup released 61 kg of greenhouse gases! That's a lot, eh? You know why? This is the process.

Factories melt polystyrene pellets and stretch the polystyrene into sheets of plastic. An oven will heat the sheets until they are soft to be shaped without breaking. Another machine will vacuum and push the sheets into the mold cavities. The molds get cut out of those sheets, which will be remelt and stretch into new sheets of plastic. The cups are stacked and push into a conveyer belt, which will transports the cups to a machine, which will roll the lips of the cups until they are round.

The Student Council created a committee to reduce the usage of plastic cups in the school to use bottles instead. There's also several classes that focused on global warming and reduced the usage of plastic cups.

Let me give u guys some tips about using bottles. Those regular old bottles from the vending machines, like the bottles from the brand Aquafina, or La Vie, have an expiration date on them. That doesn't mean that the drink expire. That means that when the plastic expired, harmful chemicals in the plastic will be released. U don't want to drink the drinks from an expired bottle.

So buy a bottle, or use a plastic cup for more than one day before throwing it away. Those bottle from the vending machines, you don't have to worry about them until a few years later. But I advise you to buy bottles that doesn't expire. You could use those bottles for your whole life!!
