Restaurants and wineries in Oregon and California are now collecting wine corks for reuse. If you want to join in, you're probably out of luck. As of now, there are only three public collection points: two in Napa, California, and one in Oregon; they're keeping the program small while they work out the kinks.
Apparently one issue is that it may consume more energy to collect and transport the corks—it takes 300,000 wine corks to yield 1 ton of recycled material, which can be turned into a number of products such as flooring. Most cork product factories are made in Spain or Portugal, near where cork trees grow, so that might be part of the logistics problem. We're hoping they can work out the transportation issues or figure out a more local use for used cork, as there's certainly enough of it. The company behind ReCork America is Portugese cork producer Amorim Irmãos, and they make 3 billion corks each year.
