Denim: the last straw in insulation

I've blogged before about using straw as insulation, and straw construction is still in the news. But Habitat for Humanity is putting an even more unusual organic fiber to use in new houses: denim. The charitable organization has been recruiting college kids in drives to collect used jeans -- for example, in West Virginia, South Dakota, and Kentucky (see photo) -- which are then recycled into insulation. Check out this article on the program in Agweek, and the campaign's official site. And, surprise surprise, the denim drive is co-sponsored by the Cotton Inc. people: good press for cotton companies, and warm houses for the poor. The denim is made into insulation by Bonded Logic.
