The forestry sector in BC is the largest in Canada. It is estimated that 10.5 million tonnes dry matter (tDM) of woody biomass are currently available for energy production in BC every year, including unharvested timbers within Allowable Annual Cut (AAC; i.e., the level of harvesting permitted by the province), trees killed by infestation of mountain pine beetle (MPB, a consequence of climate change), uncollected forest residues and sawmill residues (Wang, 2019). Of the forest and sawmill residues, 4.7 million tDM per annum are used in pulp, chip and pellet mills (British Columbia, 2019); the existing and potential trade in wood pellet fuel is discussed further in section 4.6 below. Exports of wood fuel amount to about 1.8 million tDM pa of pellets (British Columbia, 2018a) and 0.3 million tDM pa of chips (Natural Resources Canada, 2018), leaving 4.0 million tDM pa uncollected and potentially available for domestic use (Wang, 2019). In addition, at a rough estimate, about 4 million tDM of MPB-killed trees could be salvaged for energy production annually (Wang, 2019).

The engineers in Ontario Power Generation (OPG) reported their experience in modifying the existing coal pulverizer located in Atikokan power station to be compatible with wood pellet fuel on a commercial basis [2]. The OPG team reported that three critical issues must be considered in the case of using roll-race or ball-race pulverizers to crush wood pellets instead of conventional coal fuel.

The aim of this work was to study the torrefaction of pellets produced from different biomass wastes and to determine the conditions that produce an improvement in the pellet fuel quality without causing a significant degradation of their mechanical properties. MATERIAL AND METHODS

In general, the pellet fuel has been realized as pellet fuel tendency for reasons such as having less nitrogen and sulfur content possess than fossil fuels, as well as emissions and lower ash content (González et al. 2004). In this context, when looking at the pellet consumption worldwide it is seen that European countries are the biggest pellet users with 22.3 million tons. European countries with the highest pellet consumption are Sweden, Germany, and Denmark (Venturini et al. 2018). In addition, China Renewable Energy Association (CREIA) stated that in 2016 China used 9 million tons of pellets. In North American countries, this figure is about 2.4 million tons (mostly domestic heating) (Aebiom Statistical Report 2020).
