    This review summarizes patents related to paper recycling that were issued during the last six months of 2001. Two on-line databases, Claims/U.S. Patents Abstracts and Derwent World Patents Index, were searched for this review. This semiannual feature is intended to inform readers about recent developments in equipment design, chemicals and process technology for recycling paper, and alternative products derived from postconsumer paper. Only brief summaries of individual inventions are given in this review. For more complete information, readers will need to access the full text of a specific patent.
