In the past month or so, you may have noticed that some iconic red Coke bottles have a new little green stamp on the label. That's because Coca-Cola (KO) has launched a new green line of beverages in bottles with up to 30% plant-based material.

Though the name isn't very creative -- PlantBottle is the best Coke could do? -- the concept is a groundbreaking move for one of the world's biggest corporations. When a truly global brand like Coke rolls out a product like this, it forces the entire landscape of the industry to adapt.

I'm not naive about the move -- the bottom line definitely has as much as or more to do with the PlantBottle as with the consciences of higher-ups. But as consumers focus more and more on eco-friendly products and their carbon footprints, the biggest companies in the world have taken notice.

Here are three other recent eco-innovations from big-name blue chips in the same vein as Coke's plant-based bottle.

Compost-Friendly Sun Chips Bag: Coca-Cola's main rival, PepsiCo (PEP), owns the Frito-Lay brand and all the snacks under that umbrella -- including Sun Chips.

As a whole-grain snack with a name that evokes the great outdoors, it's natural to think that PEP would look to build on the green image of this snack. But a bag that can be composted? That's above and beyond. The bag is due to hit your local snack food aisles on Earth Day 2010.

100% Recycled Printer Paper: This seems like a no-brainer, but the sheer popularity of recycled paper is worth noting. All the heavyweights in office supplies from Staples (SPLS) to Office Depot (ODP) carry printer paper made from 100% post-consumer content. That means this isn't stuff from the factory floor, but actual junk mail and old newspapers repurposed for office use. Oh yeah, and the stuff is chlorine- and acid-free.

Clorox Greenworks Products: When you think Clorox (CLX), you think bleach -- and some people think of harmful chemicals. So in a bold move in 2009, the company pushed ahead with the Greenworks line of products, which feature plant-based, biodegradable cleaning agents. The products include everything from all-purpose cleaner to detergent to wash clothes.
