The biomass yield per hectare predicted for the Dawson Creek TSA is 32.3 oven-dried tonnes per hectare (odt/ha) from harvest residues. The biomass ratio, which is the ratio of recovered biomass to recovered merchantable roundwood, is estimated at 19.2%. Over the next 10 years at total of 1.59 million odt of available biomass are predicted to be generated by harvest in the Dawson Creek TSA, or approximately 160,000 odt/yr. Of this, approximately 1,242,000 odt in total, or 124,000 odt/yr, is expected to be available at the economic price of $60 per oven-dried tonne. Approximately 98% of the total predicted volume is expected to be available at $90/odt: a total of 1.56 million odt, or 156,000 odt/yr.
The average harvest residue biomass yield per hectare predicted for the Fort St. John TSA is 31.5 oven-dried tonnes per hectare (odt/ha). Over the next 10 years, a total of 2.99 million odt of available biomass are predicted to be generated by harvest in the Fort St. John TSA, or approximately 300,000 odt/yr. Of this, approximately 269,000 odt in total, or 27,000 odt/yr, is expected to be economically available at a price of $60 per oven-dried tonne. Approximately 75% of the total predicted volume is expected to be available at $90/odt, representing a total of 2.25 million odt, or 225,000 odt/yr.
Biomass sampling and analysis play decisive roles in determining the characteristics and value of the woody biomass fuel used in bioenergy systems in Canada. Sampling and analysis standards help harmonize the procedures that are used to monitor biomass quality. Because there are no Canada- wide biomass sampling standards, facilities that produce and use woody biomass have developed and implemented in-house sampling procedures of varying degrees of complexity. Given that the use of woody biomass in Canada is predicted to increase, the ability to ensure the quality of biomass will become increasingly important in order to control costs and maximize system efficiency.

L’échantillonnage et l’analyse de la biomasse jouent un rôle décisif dans la détermination des caractéristiques et de la valeur des combustibles de biomasse ligneuse utilisés dans les systèmes de bioénergie au Canada. Les normes d’échantillonnage et d’analyse contribuent à harmoniser les méthodes utilisées pour évaluer la qualité de la biomasse. Il n’existe pas de normes d’échantillonnage pancanadiennes; les usines qui produisent ou utilisent la biomasse ligneuse ont donc élaboré et appliqué des méthodes d’échantillonnage maison de niveau de complexité variable. Comme on prévoit une augmentation de l’utilisation de la biomasse ligneuse au Canada, les compétences permettant de garantir sa qualité deviendront de plus en plus importantes pour limiter les coûts et maximiser l’efficacité des systèmes.

Checking, mold and decay cause major problems for wood utilization and market value. About one third of wood products were used to replace old building materials that failed due to these problems caused by fungal infection. Products currently used for protecting wood materials from mold, decay and checking damages are mostly toxic chemicals. Development of a new generation of natural pesticides is urgently needed for meeting new regulatory requirements. Lignin produced by plants and chitosan from crustaceans have both natural antifungal and antibacterial properties. Combining both natural compounds to synergize a natural bio-protectant against molds, decay and checking is the major objective of this project.
The approaches of this project include formulate lignin and chitosan into a harmonized coating mixture for using as a bio-renewable and eco-friendly bio-protectant against fungal infection in different applications such as:
End coating on logs and green lumber against fungal attack and checking;
Protective coating on wood siding materials against fungal infection and weathering.
The results showed that chitosan and Kraft lignin are compatible. After mixing the 2 materials by stirring, it formed a homogenized brownish coating material without any precipitation. Fifteen formulations with different concentration and ratio of lignin and chitosan were evaluated. Based on the texture, color, uniformity, efficacy against fungi and economic criteria, 4 formulations were finally selected for the tests at 6% solid content of lignin: chitosan ratios of 2:1 & 1:1 and 9% solid content of lignin: chitosan ratios of 2:1 and 3.5:1.
As a log end coating, the 4 formulations were tested to protect freshly-cut sugar maple and lodgepole pine against mold, stain and checking in an outside storage for 8 weeks. On both wood species, the effectiveness of the best lignin/chitosan coating formulation was similar or better than the currently used commercial chemical product Anchorseal.
After exposure of lignin/chitosan coated or uncoated black spruce wood samples to a high humid condition for 2 weeks, the uncoated wood samples started to grow molds with 100% infection rate. Slight mold infection was found on wood samples coated with 3 formulations after 4 weeks and no mold growth was found on wood samples coated with 1 formulation (LC921) until the end of the test of 8 weeks.
After exposure to the 4 lignin/chitosan formulations coated black spruce wood samples to white-rot and brown-rot fungi for 16 weeks, the formulations LC611 and LC921 were moderately resistant to decay, as effective as using currently chemical wood preservative by dipping treatment.
The lignin/chitosan coatings were able to prevent wood fiber erosion, but they are photo degradable. However, the formulations LC611 and LC921, that contained 3% of chitosan, are more resistant to weathering than the formulations LC621 and LC972 that contained 2% of chitosan.

This preliminary study addresses the life cycle sustainability analysis subproject of the Woody Biomass Innovative Project, which proposed to assess the future bioenergy potential for British Columbia from a broad perspective that includes energy, greenhouse gas considerations and climate change, impacts on soil and biodiversity, and socio-economic sensitivities and to consider the need for guidance and policy development. This preliminary study reviews currently available assessment methodologies and proposes a framework for a life cycle sustainability assessment of current and emerging wood-based biofuel products used in three sectors (i.e., residential, institutional, and industrial) in British Columbia. In addition, this study defines data requirements and data availability for a detailed assessment, and outlines the possible policy implications that might be drawn from a detailed study.
The main objective of this project was to introduce NCC into the phenolic resin system as a reinforcing agent for improving the resin’s bond quality and durability in the manufacture of oriented strand board (OSB). The approaches adopted in this project can be outlined as follows: Develop a procedure or a new process technology to uniformly incorporate NCC into the phenolic resin system including phenol-formaldehyde (PF) and lignin-based PF resin; Develop new formulations for the NCC-phenolic adhesive system in both liquid and powder forms; Characterize NCC-PF and NCC-lignin-PF resins with differential analytical techniques; Manufacture OSB panels with NCC-PF and NCC-lignin-PF resins; Quantify the performance improvement of OSB panel by evaluating the resulting panel for physical and mechanical properties.

Canada’s wood products industry has long played an important role in the Canadian economy. It is a diverse industry, producing both commodity and value-added products in every region of the country.
This energy use status report focuses on five commodities produced within the broadly defined wood products sector: softwood lumber, softwood plywood, oriented strand board (OSB), particleboard (PB) and medium density fibreboard (MDF).
The study, conducted by FPInnovations – Forintek Division, takes a different approach than other Canadian Industry Program for Energy Conservation (CIPEC) reports. It does not focus solely on gross facility manufacturing energy use, but also puts this energy use in context by relating it to upstream energy required to procure raw material and energy inputs. In addition, the study tracks direct and indirect greenhouse gas (GHG) emissions by fuel type and accounts for the carbon sequestered in wood products and thus, presents a carbon balance for each finished product at the plant gate.
Using a life-cycle analysis approach, this report documents the cradle-to-gate energy use in the production of the five commodities, so each industry segment can better appreciate how it draws upon and uses materials and energy resources and how it may reduce its energy use in the future.
Chapters include resource extration, forest managemetn, resource transportation, softwood lumber manufacture, softwood plywood manufacture, oriented strand board manufacture, composite panel board manufacture, gross energy and carbon balance summary and energy use reduction potential in wood product manufacturing.
