Denimite repurposes blue jeans into a "green" material

As evidenced by our friend carbon fiber, composite materials get a big boost in strength when fibers are part of the recipe. Examples include composites made with plastic, wood pulp, and flax fibers. Husband-and-wife design team Jen Carlson and Josh Shear have taken this concept to a funky new level, by using shredded old blue jeans to create a denim fiber composite known as Denimite. Read More

Old CDs to gain new lease of life in ... sewage treatment?

A team of Taiwanese researchers is to demonstrate a method of treating sewage using old optical disks such as CDs. The disks are used as a platform to grow minuscule nanorods of zinc oxide, a known photocatalyst capable of breaking down organic matter. By spinning the disks, sewage water spreads into a thin layer through which light can pass, exciting the nanorods into action. Read More

But what about a robot that eats buildings? Omer Haciomeroglu of Sweden’s Umeå Institute of Design has come up with the concept ERO concrete de-construction robot, which uses high-pressure water jets to strip concrete from rebar and recycle it on the spot.
