Abstract
- This section provides answers to questions concerning paper and the paper industry. A paper's brightness is defined by the percentage of light it reflects. Papers with a higher brightness allow colors to stand out, while lower-brightness papers are easier on the eyes for reading or extended viewing. A brighter sheet usually is more expensive to make. Fillers and chemicals, such as fluorescent dyes and optical brighteners, are needed to create the paper's brighter appearance. The U.S. Environmental Protection Agency recommends paper with a minimum recycled content of 30 percent post-consumer waste (PCW) for uncoated papers and 10 percent PCW for coated papers. A lot of high quality mills offer paper that meets or exceeds these standards. Forest Stewardship Council (FSC)-certified papers are another option. This worldwide organization certifies sustainable forestry practices and encourages the use of FSC-certified paper. As for bleaching, ensure that the paper is process chlorine-free (PCF). PCF indicates that fiber is recycled and is unbleached or bleached with non-chlorine compounds. PCF papers cannot be considered totally chlorine-free because of the unknown bleaching process of its recycled content.
