The only difference about Bamboo is that is is cheap to grow and it grows fast. Processing the bamboo into other products takes as much energy and chemicals as it does any other. So to me it would seem more power and chemicals are used because bamboo grows faster to have more to process.
That's like organic foods use more harmful chemicals than the regular chemicals that are being used on non organic foods. It's easy to search for that. The media won't report those facts those.
