Every year, we use over four billion trees to make paper the industry is the world’s fifth highest energy consumer.
Finally, the reusable paper is here. It uses colour-changing nano-particles instead of ink.
By using UV light prints on the paper in seconds, the words will remain readable for over five days. You can then erase the page with heat.
The same paper can then be reprinted up to eighty times.
In the next few years, researchers are now working on cost-effective printers with hope to sell the paper to the market.
