Scrapping a Bentley is blasphemy for most enthusiasts, but if circumstances do require such action, they’re quite recyclable.

The British luxury automaker said Thursday that materials in its current line of Continentals are 85 percent recyclable, for a recovery rate of 95 percent. The company was recognized by the German Motor Transport Authority with Europe-wide certificates for the accomplishment at a ceremony in Berlin.

“Our environment policy is based on sustainable principles, and we take a holistic view of the whole process,” said Arno Homburg, head of whole vehicle development at Bentley. “At the design stage, we consider the environmental impact of all components over the entire life of the car.”

That being said, 70 percent of all Bentleys ever built are still in existence. They usually end up in the hands of collectors or museums, rather than a scrap yard.

Also green, and certainly mean, is the 621-hp turbocharged W12 Continental Supersports unveiled at the Geneva motor show. With a top speed of 204 mph, it’s hardly a hybrid. But it is the first Bentley to be biofuel compatible, and it can run on either gasoline or E85. It is the most powerful and fastest production Bentley ever.

By 2012, the company said all of its models will be capable of running on flex fuel. Bentley also is working to develop a powertrain that will use 40 percent less fuel, and wants to cut the overall carbon-dioxide footprint of its fleet 15 percent by 2012.
