This is an interesting product. I'm not so sure if the claim that it does "no damage to the environment" can really hold true, because lots of common household items that might end up being recycled in this machine could contain any number of potentially harmful chemicals. For example, one would think that a book would be fine to turn into energy by burning (it's mostly cellulose), but the glue that keeps the pages together is actually pretty harmful. So I find it inevitable that people will create toxic or harmful emissions from this product. Still, it's very nice for certain uses!
