Cintas, which designs and manufactures corporate uniforms, has introduced a new uniform shirt, the Eco Polo, which is made from recycled plastic bottles and something the company calls "eco-charcoal." The coolest thing is that used Eco Polos can be recycled once more:

Used Full Circle Eco Polo shirts can be sent back to the company to be repurposed for other uses, which Cintas said is new for the uniform market. "The biggest thing is this is a closed-loop process," said Sarah Makeijus, a merchandising manager with Cintas. "There are not many people doing this today."

The Eco Polo is the latest in Cintas' sustainability efforts with respect to its uniform business.
