The KFC Reusable Side Container has the right idea. Instead of simply making packaging more eco-friendly, why not create something that can be used again and again? So simple and ingenious, this concept recently won the 2010 Greener Package Awards.
In addition to the KFC Reusable Side Container, "KFC will reduce its use of foam by 62% and total plastic use by 17%," according to their website. With the launch of their ‘Reuse. Renew. Rejoice’ microsite, you can keep tabs on the rest of their eco ventures.
