Abstract
The absence of commercial facilities to recycle or recover value from wood treated with metal-based wood preservatives at the end of its service life is one of the most significant negative points in the generally positive life cycle analysis of treated wood. Wood treated with carbon-based preservatives (metal-free) may be far easier to recycle or recover value from since the preservatives are relatively vulnerable to thermal, chemical and biological breakdown. As a result they might be destroyed by kraft pulping, combustion or composting of treated wood. The present research evaluates the use of carbon-based preservative-treated wood in these processes. Kraft pulps produced from wood freshly treated with recommended loadings of carbon-based preservatives contained significant quantities of didecyldimethylammonium carbonate (DDAcarbonate), propiconazole and tebuconazole. However, lower preservative concentration in the wood and intensive pulping may be able to produce pulps without detectable preservatives. The azoles were also detected in significant quantities in the black liquor (DDAcarbonate was not analysed in black liquor). No azoles were found in the ash produced from combustion, but significant quantities were detected in the filtered smoke. DDAcarbonate was not detected in the filtered smoke. Analysis of DDAcarbonate in ash was inconclusive. A composting experiment has been set up and is in progress. Data on preservative breakdown during composting is expected next year.

Abstract
Recent work at FPInnovations within the Transformative Technologies program has focused on developing information to assist the Canadian Wood Preservation industry to transition to carbon-based preservation systems. One of the aims of the research is to identify ways of processing wood treated with carbon-based preservatives at the end of its service life. There is also concern regarding biodegradation of carbon-based preservatives during the service life leading to premature failure. This review summarizes what is currently known about the biodegradation of carbon-based actives and identifies knowledge gaps to guide future work in this area.

Abstract
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

Abstract
It is well known that the forest biomass used to supply the energy sector must meet the quality standards of energy production facilities. These standards relate to moisture content (TH), particle size, fine particle content and degree of contamination. Customers have their own requirements, which sometimes differ from each other, and the supplier must meet them. The development of a payment system based on quality criteria and energy value seems obvious, but not everything is the obvious, but it is not that simple.
Abstract
Devant l’enjeu des changements climatiques, tous les secteurs d’activités sont appelés à faire leur part afin de diminuer les émissions de CO2. Il en est de même avec les activités en forêt. Les différents groupes de recherche en opérations forestières chez FPInnovations se sont penchés sur la question et proposent diverses options d’atténuation. Parmi celles-ci, on compte l’adoption de méthodes plus écoénergétiques de conduite de machinerie, l’utilisation de biocarburants et la réduction des résidus de coupe laissés en forêt. Mais comme on ne contrôle bien que ce qu’on mesure, ils ont tout d’abord mis au point des outils permettant de calculer les émissions de carbone issues des opérations forestières.

Abstract
Forest biomass is a source of of renewable energy source of energy that reduces carbon emissions to the to the atmosphere. However, there is a variable period of time before bioenergy can be considered carbon neutral or as carbon neutral or beneficial in terms of in terms of carbon reduction. What is this time horizon needed to achieve benefits to the benefits to the atmosphere in terms of the amount of of carbon emissions avoided? This is what this will be discussed in this paper, using the example of a biomass heating project biomass heating project conducted by the Petite Nation Forestry Cooperative.
Abstract
La biomasse forestière est une source d’énergie renouvelable permettant de réduire les émissions de carbone à l’atmosphère. Toutefois, il y a une période de temps variable avant que la bioénergie puisse être considérée comme carbo-neutre ou bénéfique en termes de réduction de carbone. Quel est cet horizon de temps nécessaire pour obtenir des bénéfices à l’atmosphère en termes de quantité d’émissions de carbone évitées? Voilà ce dont il sera question dans ce texte, en prenant l’exemple d’un projet de chauffage à la biomasse mené par la Coopérative forestière de Petite Nation.

Abstract
Lacking the UV protection provided by copper, carbon-based preservative-treated wood used in many above-ground applications will require coating to meet consumer demand for weather resistance. While earlier metal-based preservatives were true solutions, many of the formulations of carbon-based preservatives rely on surfactants for solubility or dispersion in water. These surfactants can potentially react badly with the dispersion agents in the existing coatings on the market. The present work investigates the performance of six selected coatings on white spruce heartwood and ponderosa pine sapwood untreated and treated with one of three carbon-based preservatives. After 500 hours of artificial weathering there were few differences in coating performance between untreated and treated samples. Further weathering should be completed to potentially detect more subtle effects that these preservatives may have on coating performance.

Abstract
The absence of commercial facilities to recycle or recover value from wood treated with metal-based wood preservatives at the end of its service life is one of the most significant negative points in the generally positive life cycle analysis of treated wood. An experiment was initiated to determine whether wood treated with carbon-based preservatives could be degraded by composting without residual preservative contamination. After one year the concentration of triazoles remained high, while the concentration of DDAcarbonate was greatly reduced. This report describes the depletion of carbon-based actives from compost mixtures after a further six months of storage. Triazoles remained at high concentrations in the wood, while the concentration of DDAcarbonate was reduced. Overall, composting wood treated with carbon-based preservatives, under the conditions present in this study, was neither wholly effective nor efficient in breaking down these preservatives.

Le plan canadien sur le changement climatique prévoit une réduction des émissions de gaz à effet de serre (GES) de 17 % entre le niveau de 2005 et celui de 2020. Pour ce faire, différentes options sont envisagées: 1)l’augmentation de l’efficacité énergétique; 2) la conversion des énergies fossiles en énergies renouvelables; 3) l’adoption de plans de gestion forestier et agricole améliorés et 4) des incitatifs fiscaux pour les émetteurs de GES. Sous le contrôle de l’État, ces derniers peuvent soit réduire leurs émissions sous le niveau permis ou acheter des crédits de carbone compensatoires à ceux qui réduisent leurs émissions significativement sous le niveau permis.

Abstract
Some black stain fungi are known to exhibit resistance to carbon-based preservatives. However, the cause of this resistance is unclear. The fungi may have mechanisms to tolerate these chemicals, or they may be able to degrade and detoxify them. Fungi capable of degrading carbon-based preservatives are of interest for possible bioremediation of carbon-based preservative-treated wood at the end of its service. Moreover, such fungi could potentially facilitate the colonization of carbon-based preservative treated wood by decay fungi. Two strains of Aureobasidium pullulans and two strains of Epicoccum purpurascens were evaluated for their ability to degrade three commonly used carbon-based preservatives: propiconazole, tebuconazole, and DDAC. At low and medium concentrations propiconazole and tebuconazole were found to be vulnerable to degradation by one of the Epicoccum purpurascens isolates. Where biocides are needed to control the growth of black stain fungi on wood, a combination should be used to minimize the risk posed by resistant strains.
