The growing demand for high performance energy storage devices, coupled with more aggressive environmental policies, will only increase the opportunity for bio-sourced materials such as lignin to be applied successfully in the energy storage market in Canada and worldwide. The Canadian forestry industry, as a leading producer of lignin resources, is particularly poised to benefit economically from developments within this field.
The following presentation discusses oxy-fuel combustion for the Pulp & Paper sector, specifically for the power and recovery boiler systems in a typical kraft mill. The primary objective is to produce a purified CO2 stream that is suitable for transportation and/or utilization to achieve net-zero or negative emissions. The presentation considers and discusses the pros and cons of oxy-fuel combustion in terms of boiler operation, flue gas treatment, and performance changes. Key observations on oxy-fuel combustion are discussed, including operation mode, effects of O2 concentration, and operating pressure, with a comparison to air-fired benchmarks with and without post-combustion amine capture. Major knowledge gaps are defined to deploy oxy-fuel combustion systems, including potential next steps using models and machine learning tools (TEA and LCA) being developed as part of the National CCUS Assessment Framework.

Lime kilns are an important unit operation in the kraft pulp mill, part of the recausticing cycle essential for making pulp. Oxy-firing is a potential retrofit for the lime kiln to produce a sequesterable CO2 stream without negative impact on the lime quality. We look at the effect of switching from air-firing to oxy-firing with recycle on combustion, heat transfer, and calcination. We summarize the relevant work done in Europe for the cement kiln and its implications for the lime kiln.

CCUS for the Pulp and Paper Industry Webinars – Session 1 Video 1, a presentation by Professor Naoko Ellis
The targets set at COP26 in Glasgow call for urgent action around the world to alleviate the disastrous impact of climate emergency. Carbon Capture, Utilization and Storage (CCUS) is unanimously recognized around the world, at international and national levels, as a key pillar necessary to achieve net-zero emissions alongside energy efficiency, electrification, hydrogen and biomass. CCUS can reduce emissions from a broad range of processes, and can also compensate those emissions in hard-to-abate and hard-to-electrify processes with negative emissions through bio-energy Carbon Capture and Sequestration (BECCS). The high-level overview of the CCUS in BC will provide a framework on how to consider CCUS and some contextual issues associated with CCUS in BC

Brief overview of the storage of carbon dioxide in the form or carbon as well as carbon dioxide. Carbon dioxide can be captured more or less easily, albeit at a cost, from any process that releases carbon dioxide from the chemical processes underway. This includes fossil fuel and biomass combustion and cement production. Once captured, it must be transported to a storage location. Western Canada is a good place to store CO2. Many aspects of the nature of our geology make us a first-class storage location – much of Alberta, southern Saskatchewan and northeastern British Columbia, although central BC has some potential. A second way of very long term storage is the use of biochar (essentially pure carbon) mixed into soil. Mixed in the soil, literature suggests a half-life of at least 550 years. Depending on soil type, the biochar has numerous benefits to the soil. The porous nature of the biochar is a good substrate for beneficial micro-organisms in the soil, it holds water reducing the wilt index for plants, it can help reduce N2O emissions, store nitrogen (reducing fertilizer requirements), extract contaminants and reduce soil density in more clayey soils. As a secondary area of interest, biochar mixed with compost is a good way to move the fertilizer to the soil. Biochar can also be used as animal feed to improve growth and reduce methane emissions.

CCUS for the Pulp and Paper Industry Webinars – Session 2, Video 3, a presentation by Philippe Navarri
The urgency of climate change mitigation and the increased interest in circular economy are driving interest in opportunities to capture CO2 from industrial sites or the atmosphere for sequestration or the development of sustainable products. It is now well admitted that carbon capture, utilization and storage (CCUS) is an essential option to achieve our 2050 net-zero emissions objectives. Because the majority of CO2 emissions in pulp and paper mills is biogenic, capturing this CO2 is considered a net CO2 removal from the atmosphere. Therefore, the pulp and sector can play a critical role in helping Canada achieve its net-zero emission objective. Although CCS has the potential to deliver much larger CO2 emissions reductions, CCU is expected to play a critical role where there is limited storage capacity, in decarbonizing of hard-to-abate sectors such as aviation and maritime transportation, and in the production of "greener" products as an alternative option to replace products that would otherwise be fossil-based. A wide range of CO2 utilization technologies exist to produce a variety of value-added products including chemicals, fuels, polymers and construction materials that are often seen as a new revenue stream for the industry. In this webinar, a review of CO2 utilization opportunities to produce value-added "green" products (e.g. alcohols, fuels etc.) will be presented, their attractiveness assessed, and key aspects to consider for their implementation will be discussed.

CCUS for the Pulp and Paper Industry Webinars – Session 3 Video 1.
The following presentation discusses CO2 purification for the Pulp & Paper sector. The primary objective is to produce a purified CO2 stream that is suitable for transportation and/or utilization in an effort to achieve net-zero or negative emissions. The presentation considers and discusses the pros and cons of a variety of flue gas treatment, CO2 capture, and compression/liquefaction options for the major CO2-containing streams in a typical kraft mill. Key observations on post-combustion CO2 capture and purification approaches are discussed, including alternative strategies, such as flue gas stream blending and oxy-firing, to lower costs and improve capture efficiencies. Major knowledge gaps are defined to deploy CO2 capture and purification systems, including potential next steps using models and machine learning tools (TEA and LCA) being developed as part of the National CCUS Assessment Framework.

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.

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.
