Paper made from rocks – Who couldn’t be intrigued? For nearly a thousand years, paper was made the same way from linen, cotton and hemp rag fibers. Then in the mid-19th century with the coming of the industrial age, paper manufacturers learned how to make paper from wood. It made paper cheaper but also of a lesser quality owing to the heavy use of acid to extract the cellulose fibers needed for the process. That acid has created a crisis for libraries, archives, and museums ever since, as it eventually turns the paper to dust. Today paper manufacturers have learned how to produce acid-free paper by adding calcium carbonate to neutralize the acid, but the industry remains a highly toxic one. It is said to be the third-largest industrial polluter in the U.S., a heavy user of energy and water, and a contributor to deforestation. While recycling paper helps the industry’s environmental impact, it still requires intensive industrial processes. Now the papermaking process is poised to undergo another revolution. Paper can be made by g...
