“…This process has been studied on a large variety of feedstock applying different torrefaction settings (e.g., temperature, and time) mainly on lab-scale [8] and most recently also in pilot scale plants [9]. Several technological innovations were made over the past years to bring the process to commercial scale [10] and techno-economic assessments assuming European and Northern American conditions were conducted [11,12]. In both cases, the now more homogenous, brittle and hydrophobic material is compacted to pellets and can be transported, stored for prolonged periods and delivered as a boiler fuel.…”

“…purchasing heater and installation are highly complicated. Biomass is highly labour concentrated than customary gas or oil establishments unless a container is used to keep it finished up with pellets or chips [15,16]. It's actually that bio-pellet boiler should get clean frequently after every use.…”

“…Based on previous literature (Pirraglia et al 2010b) and current models being developed (Pirraglia et al 2012b;2012c), the costs for producing wood chips, wood pellets, torrefied wood, and torrefied wood pellets have been assessed, and these costs include transportation (delivered cost) of the biomass to the facilities with a maximum transportation distance of 50 miles. Considerations for economies of scale are taken into account with the calculation of each production cost at factory gate.…”

“…In this sense, previous work performed by the authors indicate the necessity of adding either steam conditioning (treatment selected for the torrefied pellets described in this research due to its lower production costs), or binders (Distillers Dried Grains, feed corn, soybeans, etc.) in order to manufacture durable pellets that are adequate for transportation (Pirraglia et al 2012c), increasing the production costs of this pretreatment. The characteristics of this new technology and its combination with a pelletization process must be carefully assessed in its economic and technical aspects, as well as evaluating the selection of biomass for such a product.…”
