Environment friendly plastic bottle

Coca-Cola Co. is developing a new type of bottle that could replace at least some of the
environmentally harmful plastic.It and other beverage-makers now use with more Earth-friendly material made from sugar cane and molasses. They call this project "PlantBottle".
A Coca-Cola spokeswoman said
"the PlantBottle is one of many methods the company is exploring to make its packaging greener."
Lisa Manley said
"We're interested in developing the packaging of the future, which we think is going to be in some ways derived from either plants or something else that is a naturally occurring resource that's not under stress like petroleum."

Coke's new type of bottle would be made from a blend of petroleum-based materials and up to 30 percent plant-based materials. It's initially being made with sugar cane and molasses, a byproduct of sugar production, but other plant materials are being explored.
The blend could make the recycling process easier and cheaper, and reduce the time discarded bottles sit in landfills.
Plastic bottles today are made from a petroleum-based resin known as polyethylene terephthalate. PET bottles are recyclable, but the process can be relatively expensive and complex. PET bottles that aren't recycled can take years to decompose.
Coke is one of the biggest producers of plastic bottles, which are a bane of environmentalists. Consumers drain about a billion PET bottles every week, and only 18 percent to 23 percent are recycled, says the Container Recycling Institute, a nonprofit advocacy group in Washington.
