Cascades invests in cellulosic sugar technology at Cabano

April 15, 2015 - Cascades Inc. will replace the pulping process at its Norampac Cabano facility with a hot water pulping process that will allow the plant to extract hemicellulose, a cellulosic sugar with high value-added potential, from wood chips. It will be the first time this innovative process is used in Canada.
This $26-million project is a step forward for biorefining in Canada. It is backed by a $10-million investment from Natural Resources Canada’s Investments in Forest Industry Transformation (IFIT) program and an additional $4.4 million from the Québec Ministère des Forêts, de la Faune et des Parcs.
The Cabano plant, located in Témiscouata-sur-le-Lac in Eastern Quebec, manufactures corrugated medium from virgin and recycled fibres. Cascades will replace the plant’s current process – the production of sodium carbonate-based chemical pulp – with what it describes as a more environmentally friendly and economical process that was developed in conjunction with a U.S. partner.
The hot water pulping process will be used to extract hemicellulose from deciduous woodchips.
Hemicellulose is a natural polymer found in plant cell walls. A fact sheet from the IFIT program explains that with this hot water pulping process, Cascades will be able to extract the hemicellulose from hardwood chips at the beginning of the pulping process (referred to as pre-extraction). This process will result in a new value-added product, a concentrated hemicellulose stream, that can be sold as a concentrated form of wood-extracted sugars. This new product has various commercial applications, including bioenergy and a sweetening agent in food and beverages.
“This project represents a unique advance in biorefinery technological development. This new process will enable improvements in the efficiency and competitiveness of our Cabano plant’s current corrugated paper production process, thus making existing jobs more secure,” said Mario Plourde, president and CEO.
Laurent Lessard, Quebec’s Minister of Forests, Wildlife and Parks, commented: “These are the kind of technological advances that will enable our forest industry to differentiate itself and that will also create prosperity for our regions.”
Cascades produces, converts and markets packaging and tissue products that are composed mainly of recycled fibres.
