If you're a jet set environmentalist you'll be glad to see this new product. Sustainable Cards has been working with the hotel industry to offer key cards made from wood...sustainably harvested wood from PEFC certified forests in fact. Not only do the cards have a great design and feel, they are biodegradable so they also reduce the over 1,300 tons of plastic waste that traditional hotel key cards generate in the U.S. annually which is equal to the volume of seven 777 airplanes. The wooden card has been used in Europe for several years now but is just now making its debut in the US. With over 70,000 hotel guests using them during the 2008 Democratic Convention in Denver, the little key cards are creating a big buzz. Next time you're on the road, as the front desk if they will be making the switch too.
