WMU Paper Pilot Plants and Valmet have partnered to install a Valmet IQ Quality Control System (QCS)
Valmet's quality control system uses intelligent scanners, precise integrated or standalone measurements, and advanced control applications for monitoring and optimizing end-product quality in board and papermaking. Adding the IQ Scanner at the pilot plant will give WMU students hands-on educational experience with this latest automation technology.
Identification and characterization of sticky contaminants in multiple recycled paper grades

Abstract Organic sticky contaminants represent one of the biggest technical challenges in the paper recycling process. These contaminants reduce paper strength, cause plugging of wires and felts, and stick to or deposit on machine parts affecting the runnability of the paper machine. The removal of these sticky contaminants is difficult to achieve along the process due to the heterogeneous nature of these organic contaminants. In this study, the nature of sticky contaminants in multiple wastepaper grades was analyzed and characterized using screening, solvent extraction with subsequent analysis such as FT-IR, GC-MS, and SEM. The content of stickies in wastepaper varies among different paper grades and their recovery methods. The wastepaper from curb side collection contains nearly 4 times the amount of stickies than most of the wastepaper grades collected from a local paper recycling mill. Polyvinyl acetate polymers, styrene butadiene rubber (SBR), paraffin waxes and polyamines are the major components in the extracted sticky contaminants. In addition, these stickies deposit heavily on fibers surface leading to high negative charge in fibers suspension ranging between 2 and 4.5 μeq/L. It is expected that these findings will assist addressing the knowledge gaps in understanding the nature of stickies and their behaviors, and to eventually develop highly efficient technologies for contamination removal in the paper recycling process.
Hemp Innovation Foundation Funds Hump Recycles Research Study
Hemp Innovations Foundation (HIF), a nonprofit sister organization of the National Hemp Association (NHA), has awarded a grant to fund the Hemp Recycles research project. The goal of the project is to determine the viability and sustainability of using hemp fibers for paper making versus traditional wood paper pulp, and to create “regional hemp fiber and pulp supply chains with local farmers, thereby invigorating the domestic economy from field to sheet,” according to a press release. Hemp Recycles is conducting the project in partnership with Western Michigan University.
