In papermaking, a slurry of wood fibres, which are approximately 2 millimetres long and 30 microns in diameter, is drained through a forming fabric. In this drainage process the fibres get trapped by the fabric as the water drains through it. The actual drainage process is obviously highly complicated because the forming fabric geometry is […]

The three main components in wood chips are cellulose, hemicelluloses, and lignin. Traditionally, cellulose is the main constitute of pulp, which is the product of pulp mills and is used as the main raw material for paper production in paper mills. The lignin, however, is mainly burned to supply the heat requirement of the pulp […]

The management of ash residues has been a major problem for pulp and paper mills worldwide due to their characteristics and the large amounts generated. The combination of increased generation of ash residues, stringent landfill policies and increased cost is pushing mills to search for innovative ways to manage their ash residues. As a result, […]

  AV Nackwai is part of a new and innovative group of companies (AV Group), which are focused on producing specialty pulp products to service the textile and paper industry. The blow heat recovery systems, more popularly known as “The Black Hole,” is one popular area where the pulp and paper industry has utilized the […]

BCTMP (Bleached chemi-thermo-mechanical pulp) or HYP (high-yield pulp) is an important sector in the Canadian market pulp business, and most of them has been exported to Europe and Asia and over half of it is used as middle-ply furnish in Folding Boxboard (FBB). FBB requires high bending stiffness for crush resistance, z-directional strength for preventing […]

Extractives and various polymers found in wood pulp have deleterious impacts on a number of industrial processes, as well as on papermaking productivity. Such impacts have to be considered too in the emerging field of biorefining (production or extraction of high value products from forest biomass). The main partner to this project (Buckman Canada) has […]

Lake Utopia paper mill as part of the J.D. Irving, Limited (JDI) is believed to be one of the leading mills in preserving the environment. Specifically water quality is very essential for the mill since the waste water of the mill is currently depleted to the Letang estuary after treatment. The mill production has been […]

Hemicellulose is the second most abundant renewable polysaccharide, and the HMCbased microgels have great potential in the application in various industries of surface coating, oil recovery, printing, and diaper industry. In this project, the HMC obtained from FPInnovations’ novel fractionation process will be used as the raw material to prepare HMC-based microgels. The fundamental properties, […]

Two interns will collaborate with Neucel Specialty Cellulose (Neucel), which is located in Port Alice, British Columbia. Neucel is one of the leading global manufacturers of dissolving pulp, which has very high alpha-cellulose content (90 percent and over). The mill has identified the big variation in the solids content in its concentrated red liquor fed […]

AV Nackawic is part of a new and innovative group of companies (AV Group), which are focused on producing high-quality dissolving pulp and other products. For dissolving pulp, the pulp reactivity in the subsequent converting process is an important parameter, which ultimately determines the quality of the product. This internship will investigate the solutions to […]

This project will support improvements to deer management in Nova Scotia. Improved management and conservation of Nova Scotia’s most important big game species supports wildlife habitat conservation by NS DNR, but is also of importance to the forestry industry, and stakeholders such as the NS Federation of Anglers and Hunters, and the Fur Institute of […]

AV Cell, located in Atholville, New Brunswick, produces high-quality specialty cellulose (dissolving pulp). As an integral part of the manufacturing process, it operates a modern internal circulation (IC) anaerobic reactor system that handles the mill effluent while producing bio-gas that feeds to the boiler. The objective of the project is to enhance the performance of […]
