Read the passage below and decide whether the statements are TRUE or FALSE?

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