Washington, September 13 ANI: A company, based in Chicago, US, has produced 100 per cent tree free paper, which implies paper made without any usage of products from trees. According to a report in ENN Environmental News Network, the company in question is GPA, a Chicago paper company, which has produced 'Ultra Green paper' - a 100 per cent tree free paper.Ultra Green is made from inorganic mineral powders derived from limestone and calcium carbonate, with a trace amount of non-toxic resin and high density polyethylene HDPE as a binding agent, and no usage of chlorine.GPA said that the paper combines the printability of a traditional paper product with the durability of a plastic sheet. It does not require special inks or manufacturing processes.Some advantages of the paper are that it won't yellow or become brittle, no matter how long it's exposed to sunlight. The paper is resistant to scuffing, water, grease and oils and can be used outdoors without being at risk from decomposing. Also, it offers antimicrobial protection and conforms to FDA standards for food contact, and due to the water and energy savings made in its manufacturing process, Ultra Green paper is priced 30 to 40 per below than regular synthetic paper and film.According to Environmental Defense's paper calculator, replacing one ton of traditional paper with one ton of Ultra Green paper saves 20 trees. It also eliminates 42 lbs of waterborne waste, 7,480 gallons water/wastewater, 167 lbs solid waste and 236 lbs carbon emissions. ANI
