Angie, according to what the newspaper and our coverage here, it sounds like some type of coating is put on that insulated the cups (chemical application resulting in them not being as biodegradable)
I mean Obama has the right idea, new and better cups for hot drinks, and reuseable pichers and drink bottles that are washed and reused for water consumption. And great that they are starting a garden. But I am not so sure that buying new instead of finishing the rest of the already available coffee/tea cups.
