Office parties and picnics are always a problem for the ecologically minded--we'd rather not use disposable paper plates & cups. The biodegradable ones carried by the coop are an interesting option, but they have to be discarded in compost, not regular trash, as they won't biodegrade in a landfill.
Here's something new & interesting -- cups made of jello that can be used at parties or picnics, and eaten after you drink from them. While we're not trying to endorse Jello in particular, the idea is clever, and we'd like to see more innovations like this. BTW, the company says this product is vegan, made without the animal products found in most gelatins. Read about more it here.
