Hmm.
“The Glass Packaging Institute recently announced that its members will aim to use at least 50 percent recycled glass in their jars or bottles by 2013. Currently the institute estimates that the average recycled content in glass containers is about 25 percent (but 60 percent for Europe, which is better at recycling). Some states mandate it: in California, all glass beverage containers must include 35 percent recycled glass, and 50 percent in Oregon, according to the Institute.
Recycled glass goes into an array of things, like jewelry and even colorful mulch.
Plenty of glass also goes into making more wine bottles. The Gallo Glass Company, a California bottle maker, uses 35 to 55 percent recycled glass in its clear bottles, and up to 80 percent for dark green bottles. One benefit is that recycled glass “doesn’t take as much energy to turn it back into molten glass,” according to Mike Ball, a technical specialist there. Green glass, he said, is able to use more recycled content because it is darker, whereas clear (or “flint”) glass with high recycled content is prone to streaking — “like somebody has taken a crayon” to the bottle, he said.”

“Anchor Glass Container’s Kathy Richter told ISRI’s meeting in Las Vegas last March, “Our plants aren’t getting enough and we want to buy more. At glass container plants, we want color-sorted, contaminant-free post-consumer bottles and jars.” Currently, there are 69 glass container plants in the U.S., each using cullet to make new bottles and jars.”
