There are upper limits on the percentage of the world's newsprint that can be manufactured from recycled fiber. For instance, some of the fiber that enters a recycled pulp mill is lost in pulping, due to inefficiencies inherent in the process. According to the web site of the U.K. chapter of Friends of the Earth,<ref>[http://www.foe.co.uk/resource/briefings/paper_recycling.html Friends of the Earth]</ref> wood fiber can normally only be recycled up to five times due to damage to the fiber. Thus, unless the quantity of newsprint used each year worldwide declines in line with the lost fiber, a certain amount of new (virgin) fiber is required each year globally, even though individual newsprint mills may use 100% recycled fiber. Many mills mix fresh fibers along with recycled fibers to promote sustainability.
