CINCINNATI – Plastic or … a different plastic?

Procter & Gamble said Tuesday that it has started producing some of its shampoo bottles from a plastic made from sugar cane because it’s a renewable resource.

Customers won’t notice a difference, the company said, but the environment will: Most traditional plastics are petroleum-based.

The company is starting small with the sugar-cane bottles, replacing the traditional plastic in Pantene’s Nature Fusion collection in first Western Europe and then spreading to the rest of the world over the next two years.

Last month, PepsiCo Inc. unveiled a new plastic bottle made from switch grass, pine bark, corn husks and other natural materials.

Procter & Gamble has said it hopes to replace 25 percent of its petroleum-based materials with renewable materials by 2020.
