Paper Recycling

WPS Home : Research : Research Centers & Initiatives : Paper Recycling

The Department of Wood & Paper Science at NC State (WPS) has long been active in research involving the recycling of paper, pulp and fibers. Current projects focus on recycling techniques related to de-inking, the removal and effects of stickies, repulping of wax-containing paper and automated, high-speed sorting of recovered papers.

We have also been involved in understanding how new types of surfactants based on renewable materials (sugar and protein-based surfactants) can be used effectively in ink removal from recycled paper via flotation deinking. By applying green chemistry approaches we aim to minimize the environmental impact of deinking agents and also to open an avenue for a number of products that are to be generated from the utilization of biomass.

Our laboratories for paper recycling are extensive, including lab-scale pulpers, screens, cleaners, washers, flotation cells, dispersers, handsheet molds, etc.  Characterization of recycling operations and recycled paper quality can be performed with our extensive paper testing labs. Optical properties and contaminant counting (microscope and flatbed scanner types) equipment is available. Adhesive contaminant detection equipment such as the Pira Deposition Tester and other methods such as TAPPI Standard Test Method T277 can be performed.  Fundamental studies of recycling operations can be conducted with our extensive surface and colloid equipment.

Our pilot plant facilities include all of the major recycling operations as well as a paper machine. 

We continue to offer cutting edge research, technical service and education in the field of paper recycling for the world.
