Bioenergy and greenhouse gas emissions: the figures tell a story
We’re making impressive headway with reducing greenhouse gas emissions. According to the Forest Products Association of Canada (FPAC), its pulp and paper members, including Tembec, have reduced greenhouse gas emissions by 84% since 1990. Many of our facilities use biomass (such as tree bark and sawdust), pulping liquor, and treatment plant sludge to produce bioenergy for our plants. This reduces our dependence on fossil fuels used to produce heat and steam. As well, our green electricity is either used internally or sold to utilities.
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. Ethanol is another co-product used in a wide variety of products including white vinegar, pharmaceuticals, liquid detergents, and various personal care products such as hand sanitizers and body sprays.
Biogas: waste not, want not
The consumption of natural gas at our Temiscaming high-yield pulp plant has been reduced by 45% (2003 compared to 2010) as a result of anaerobic production of biogas and other improvements. 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. A third anaerobic treatment facility is also now under construction for the Matane high-yield pulp operation.
