Scientists Turn Paper Waste Into Aerogel (inhabitat.com)
Kristine Lofgren writes: A team of scientists have successfully turned paper waste into aerogel. Aerogels are used in insulation, and they are usually made out of polymers and silica. But a research team at the National University of Singapore managed to make the highly sought-after product using recycled paper, which could have huge implications not only for the rate at which we are filling up our landfills, but also for the amount of chemicals that we are producing and releasing into the environment.
Recycled paper is already used to make cellulose insulation, and has been for many years. By necessity it is full of flame retardants. It is nothing new.
The actual article only mentions insulation in passing, in the picture it looks more like a standard foam product. Nothing like cellulose insulation. They hope to initially use it for cleaning up oil spills.
Nope, very easy in fact. Shredded paper is one of the best roof insulations you can get and it is treated with boric acid to make it fire retardant. Here is a link to someone hitting Cool or Cosy (a brand name version of shredded paper insulation) with a blow torch.
