    I was curious, so I did a little searching. I was surprised to see that there are actually eco-friendly biodegradable cold drink cups that are made out of corn. I guess it's true that you learn something new every day.

    Cornstarch-based packing peanuts have been around for almost 20 years now.

    So the right question to ask here is: what will happen if temperature exceeds 105 degrees F or under direct sunlight? Is there any harmful chemical will be released under this condition? How long is the longest trace study of this material in direct human contact?

    It's been a long time since I've thought about the biodegradable packing peanuts. When they first became available, I put some into a bucket of water just to see what would happen. They started to break down immediately.

    I wasn't aware that they've been making clear drinking cups out of a corn-based formula. I guess if there are any trace studies being conducted, they probably haven't been going on for long.

    The original question was about eco-friendly cups for cold drinks. The temperature of a cold drink shouldn't get high enough to melt the cup or make it start to break down, unless the customer leaves the drink out in the sun or in a hot car - which you shouldn't do with plastic bottles or cups anyway.

    I would much rather see cafes use these eco-friendly cold drink cups, instead of letting a customer bring in their own cups to re-use.

    Here is another place that sells the cups:

    I just don't want them compromise human health/lives for ANYTHING because even compromise human lives for other human is WRONG!

    You already know biodegradable packing peanuts will break down immediately in water, so they must use something to hold those cups together under the same condition. What that thing is? Is it safe to consume? 105 is a very low temperature: what if you use this kind of cups right after you eat hot food/drink? Your lips temperature will be higher than 105 at that time.

    I don't think a person's lips would be higher than 105 degrees after eating hot food or drinking a hot beverage.

    A person's normal body temperature is 98.6 degrees F. Drinking a hot beverage can cause an immediate mean temperature elevation of 2.6 degrees. So, at less than 101 degrees, there would be no problem. The person's lips would cool off fast because of the temperature in the room, and the cold beverage that they are drinking would cool the lips instantly. There would be no risk of the cup degrading at that point.

    The cups would be safe as long as they are shipped, stored, and used in an environment that is less that 105 degrees. I wonder how they are working out for the businesses who are currently using them.

    The right question to ask is what will happen when temperature exceeds 105 degree.

    For plastic water bottles, people already did extensive study. For example, they are exposed to 39F (4C), 77F (25C), and 158F (70C) and levels of BPA and antimony were checked after one, two, and four weeks. Antimony concentrations in the water from plastic water-bottles averaged 3.18 ng/L at 39.2F (4C), and 6.88ng/L at 77F (25C). At 158F (70C) (about the temperature in a car on a hot summer day), levels of antimony in water increased significantly to 38.5 ng /L. Levels of antimony in one of the sixteen water bottles increased to 2604 ng/L. In other words, you know exactly what you will get if you expose them to higher temperature. But can you say the same about those "bio-friendly" cups?

    Now why they didn't do the same tests on those "bio-friendly" products? Does this have anything to do with the stupid political propaganda? Then why they don't treat all products equally?

    I've been using Green Strip cold cups / lids / straws for YEARS (7-... every once in a while I will get some lids that are bit brittle that must have received some heat. Otherwise I have no issue with these at all. You do have to keep them away from sunlight or heat. For example, when I just have ice left in my drink and I leave it in my hot car - it will shrink - kinda like shrinky dinks for those who know what those are

    The only, and also the most important information missing on any of these "bio-friendly" cups/products is FDA approval!

    While all other food related products, including regular plastic cups and even the parts used in your coffee machine, all have to be FDA approved.

    Interesting, isn't it?

    Musicpan,

    I'm glad the Green Strip cold cups are working out for you. Did you experiment with them before you decided to use them full time? I probably would have taken one and given it a blast with a hair dryer just to see what would happen.

    I remember Shrinky Dinks .... and after doing a Google search a few minutes ago, I discovered that they still sell them.

    If a grocery store sells none FDA approved food and they know those are not approved, can they be sued when people find out?

    If a restaurant uses none FDA approved equipment to prepare food and they know those are not approved, can they be sued when people find out?

    Can they use "bio-friendly" as defense in American courts?
