Paper can be recycled by reducing it to pulp and 1combine it with pulp from newly harvested wood. As the recycling process 2causes the paper fibers to breakdown, each time paper is recycled its quality decreases. This means that 3either a higher percentage of new fibers must be added, or the paper down cycled 4 into lower quality products. Any writing or coloration of the paper must first be removed by deinking, which 5also removes fillers, clays, and fiber fragments. Almost 6all paper can be recycled today, but some types are harder to recycle 7than others. Papers coated with plastic or alumium foil, and papers 8that are waxed, pasted, or gummed are usually not recycled 9because the process is too expensive. Gift wrap paper also cannot be recycled 10due to its low quality
