Bioenergie La Tuque (BELT) has targeted the production of renewable liquid hydrocarbon fuels (mostly diesel and aviation fuel) from forestry residues. The production of this type of biofuel is an important and necessary factor enabling Canada to meet its greenhouse gas emission reduction targets. Its importance rests on the potential inherent in the utilization of abundant and sustainable lignocellulosic feedstock, which does not compete with food as well as its complete compatibility with existing transportation fuel markets. BELT’s technology assessment team employed a systematic approach to identify mature technologies with the potential to meet the needs of BELT’s proposed biorefinery. A stepwise approach was used to sift through a wide range of biomass conversion technologies. The first fourteen (14) technologies were selected from a list of over 600 technologies by eliminating those that were not appropriate for the required conversion, lacked the necessary technological maturity, or were defunct.
FPInnovations was approached to investigate the extraction of tannin from tree bark in British Columbia (BC). FPInnovations has been working on bark extraction over the last few years and
proposed to focus this study on Western Hemlock which showed high tannin content in previous work. The extraction method developed by FPInnovations uses chemicals and elaborate
equipment that requires the work to be conducted under strongly controlled conditions, such as a chemical laboratory. This report aimed to find a simpler extraction protocol that could potentially be used by coastal First Nations communities or other parties interested in extracting tannin from bark at a relatively small scale.
