The Merchandise Mart is featuring a "Green Product Gallery" on the main floor featuring some very innovative and creative products. Even the banners advertising the display are biodegradable.
Here's the text from the images in case it's a little hard to read:
Second from bottom: EcoGen™ marks the start of a new ecological generation. The average plastic container will last a million years after disposal. EoGen™ products are 100% biodegradable and will decompose in six to nine months when properly composted.
Bottom Image: Printed on BIOflex™, a completely biodegradable PVC material
You can get more information on BIOflex™ at http://www.ultraflexx.com.
It's great to see these products getting some floor space at the Merchandise Mart. Hopefully they'll be getting more in the future not only at the Mart but on store shelves.
