How waste paper turns into a valuable high-tech material

(ORDO NEWS) — Scientists from the National University of Singapore have developed a technique for converting paper into an incredibly lightweight material with high insulating properties. Most aerogels are made from silica, although there are some rather exotic versions made from graphene and gold. However, Singaporean scientists managed to come up with a method for obtaining airgel from waste paper. The process is surprisingly simple: paper is shredded and mixed…
