Is Your Water Bottle Really Made From Recycled Plastic?

A green accounting method called “mass balance” certifies that something was manufactured with recycled plastic — just not necessarily much of the bottle making the claim.

The plastic CamelBak bottles displayed in a Target in East Hanover, N.J., offer a promise to ecologically conscious buyers. On the front of each is a bright blue sticker with the words “Tritan Renew made with 50% recycled material.”

In reality, however, the amount of recycled plastic that went into making the bottles may be nowhere near 50 percent.

Eastman Chemical, a company with $9.2 billion in annual revenues based in Kingsport, Tenn., introduced the durable plastic called Tritan Renew four years ago, telling manufacturers it was made with “up to 50 percent recycled content from waste plastic.” It quickly caught on with companies trying to reach their sustainability goals or eager to appeal to consumers who want to keep plastics out of landfills and oceans.

Dozens of brands now use the material. CamelBak and Nalgene use it in sports water bottles. Ferragamo offers Tritan Renew sunglasses. Stanley Black & Decker even made a new power tool line called Reviva from the plastic. But there is no guarantee that any particular bottle, power tool or pair of sunglasses actually contains recycled plastic.

“It could be a very low percentage that is physically in there; it could be a high percentage,” said C. Jason Pierce, a senior technical leader for the Circular Economy and Life Cycle Assessment at Eastman Chemical, when asked this spring about the amount of recycled plastic in Tritan Renew that is used to make water bottles sold by CamelBak and others. “You can’t know how much.”

So how does Eastman make its claim that Tritan Renew contains up to 50 percent recycled material? It uses a green certification system called “mass balance.”
