Paper waste converted into eco-friendly aerogel

Known as "frozen smoke" because of their milky translucent appearance, aerogels are among the world's lightest solid materials. Consisting of 99.8 percent air, they're highly heat-resistant and are an excellent form of insulation. Now, scientists at the National University of Singapore (NUS) have used paper waste to create one.Read More

Urine-powered socks get transmissions flowing

Peeing in one's socks may not be everyone's first choice for powering their mobile devices, but apparently it could be an option. A team of researchers from the Bristol BioEnergy Centre at the University of the West of England is experimenting with a pair of socks that use urine to generate electricity via miniaturized microbial fuel cells. Results have already started to trickle in, with the system used to run a transmitter to send wireless signals to a desktop computer.Read More

Slaughterhouse waste could be made into yarn

Ever since the late 19th century, people have experimented with making textiles from natural-source-based gelatine, as a cheaper and less allergenic alternative to wool. Although the emergence of synthetic fibers largely put an end to that, a new technique may yet allow gel-based yarn to see the spotlight. The fiber is said to have an insulation quality similar to that of Merino wool, and the collagen used to produce it can be obtained from waste at animal-processing facilities.Read More
