Scientists Have Invented ‘Rewritable’ Paper

Even though we are living in a digital age where technology innovations and trends are an inseparable part of people’s lives, still we all rely on paper and ink. In order to reduce this waste, with the help of advanced technology, scientists have created new, low-cost and Eco-sustainable type of paper, which requires no ink. Renewed scientist and electrical engineer Oded Kariti reminds that paper waste is currently one of the biggest environmental issues, and highlights the meaning of coming up with a solution for this global matter. Using UV light, which causes electrons from the titanium oxide to move to the dye in the nano-particle, will allow scientists to print this paper. Any writing or image can last for up to five days and can be erased by heating at 120-150˚C. This new, rewritable paper can be reused up to 20, 40 or even 80 times. Apart from environmental reasons, Oded Kariti asserts that this type of paper will be extremely useful for the increasing deforestation.
