Forest-origin biomass estimates were made by FPInnovations for a location in Northern Alberta, largely following the process previously established for six BC Timber Supply Areas using FPInterface (2010 13). The biomass inventory was based on 20-year harvest and road network plans for Crown land provided by Alberta Agriculture and Forestry as well as local forest tenure holders.

Current forest management policy in many jurisdictions in North America manages excess woody debris by piling and burning it, mainly as a post-harvest fire hazard abatement obligation. This study highlights three key points to consider regarding utilization and disposal of waste wood piles:
1) Allocate most woody debris waste to the biofuels sector in a cost-effective manner;
2) Allocate a small portion of woody debris (e.g. 10-15%) to implement windrow habitats where necessary to maintain mammalian biodiversity on clearcuts;
3) Limit burning of waste wood to those sites near human activity (potential fire hazard) that do not have an opportunity for biofuels or windrow purposes.
Le présent rapport donne des estimations détaillées des coûts actuels, à destination, des bois ronds de qualité sciage et de qualité pâte, de même que des coûts de la biomasse forestière récoltée dans un système intégré à la récolte des bois ronds. Trois systèmes différents ont été étudiés: la récolte par arbres entiers jusqu'en bordure de route, la récolte par bois tronçonnés intégrés au déchiquetage d'arbres entiers, et la récolte par bois tronçonnés. Les études ont eu lieu dans deux types de sites représentatifs:un site résineux boréal et un site mélangé acadien. Les résultats sont présentés en $/m3 et en $/tmv (tonne métrique verte) pour les bois ronds ainsi que pour la biomasse et du taux d'utilisation des machines produisant la biomasse sont analysés. D'autres facteurs qui affectent la viabilité de la biomasse forestière comme source économique d'énergie font l'objet d'une discussion.
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.

Abstract
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.

This report presents the development highlights for the BiOS app completed in 2018-2019 by FPI. An updated methodology is defined to help FLNRORD fully integrate the BiOS app data point collection into the Forest BioGis web platform. A visual roadside pile volume estimator was also developed and implemented into the BiOS app. This visual estimator will need to be calibrated and further developed with roadside pile recovery trials performed in various BC conditions. Finally, a four-year development plan is proposed to have a fully validated set of tools in the Forest BioGIS web platform and the BiOS app.
Hardwood flour was biologically converted with 3 fungal species, and ammonium lignosulfonate was biologically modified with 3 enzyme cocktails.
Ten types of panels were made of bio-modified or unmodified wood flour and ammonium lignosulfonate. All panels were manufactured at target density (850 kg/m3), temperature (220°C), pressure (300 psi) and pressing time (220 sec) without any resin and additives.
Among all formulations, the biomaterials, consisted of bio-modified hardwood flour by the fungal specie 332A, or bio-modified ammonium lignosulfonate by enzymes extracted from 76A and 329A, were most effective and showed significantly higher internal bonding (IB) strengths.
Further investigation of the bio-modification of the kraft lignin for bio-composites is conducted in 2013-2014 financial year (ongoing) and will be reported in 2013-2014.
This study addressed biomass availability, harvesting, transportation, and chipping costs for the production of bioenergy in the Teslin region of Yukon. It revealed that significant volumes of standing timber below 20 cm in diameter at breast height (DBH) exist that could be utilized for bioenergy. These volumes, however, would sustain only small electricity generation capacities; however, a more efficient solution would be to utilize the biomass in district heating applications. The study also estimated harvesting, transportation, and chipping costs of low- and high-mechanized systems. These costs will have to be further validated and incorporated into an investment calculator to assess the feasibility of future bioenergy projects in Teslin.
