While at a short course last week, I won a prize for correctly answering a trivia question about per capita use of paper in the United States. My prize was a polo shirt made of recycled PET made by 8bottles.com. The company uses 8 soft drink bottles for each shirt (hence the company name). Even the buttons are made of recycled PET. The shirt is not dyed, and takes its color from the bottles. The shirt itself can be recycled once its service is over. New shirts cost $40.
