DescriptionThis review summarizes patents related to paper recycling that were issued during the first 6 months of 2001. Two online 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 post-consumer paper. Only brief summaries of individual inventions constitute this review. For more complete information, readers will need to access the full text of a specific patent. The patents are organized into the following broad categories of recycling: equipment and related processes, chemicals and related processes, products made from recycled paper, and products designed to be more recyclable.
