Temiscaming green energy project: environmental benefits
The centerpiece of the project is an electrical turbine, driven by steam from a boiler that uses as fuel waste sulfite liquor, a residual of the pulping stage of specialty cellulose manufacturing. In brief, we turn waste into a valuable co-product – electricity – and extract full value from wood fiber. The steam is also used in our manufacturing process, reducing the need for fossil fuels, which acts on carbon and climate change. Finally, a new scrubber and environmental control equipment will reduce sulfur dioxide emissions by 70%. All this is above and beyond the project’s many business benefits.
Our biorefineries: good for us and good for you
In addition to producing bioenergy, our biorefineries in Temiscaming, Québec and Tartas, France produce specialty cellulose, which is derived from wood. Our specialty cellulose, which is highly refined, has few impurities and a high degree of brightness. Different grades of it are manufactured according to exacting customer needs. It can be used in a diversity of markets including pharmaceuticals, food, cosmetics, construction, inks and coatings. Our biorefineries also produce co-products such as lignins which can be used to create green energy and for a variety of applications such as animal feed, dust suppressants and construction.
Biogas: waste not, want not
The consumption of natural gas at our Temiscaming high-yield pulp plant has been reduced by approximately 40% since the startup of the anaerobic wastewater treatment plant. How do we do that? We remove organic pollutants from wastewater that are then converted by microorganisms to biogas, which is ultimately used to replace natural gas. We also have anaerobic treatment facilities at the Tartas, France, specialty cellulose facility and the Matane high-yield pulp mill.
