The objective of this Forest Service study was to evaluate the environmental impacts associated with converting post-harvest forest residues left to air dry into renewable bioenergy products: briquettes and torrefied briquettes. Near-woods operation of bioconversion technologies were investigated to overcome the logistic challenges of forest residue availability as biofuel. Data were generated as a part of the Waste-to-Wisdom project through a pilot scale near-woods integrated operations of torrefier and briquetter units. Life cycle assessment tool was used for environmental sustainability assessment, evaluating the entire supply chain of production using a cradle-to-grave approach. Substituting torrefied briquettes and briquettes for fossil fuels revealed notable decreases in greenhouse gas emissions. In addition, valorization of low-value forest residues to produce bioenergy carriers resulted in considerable environmental advantage from avoided pile-and-burn emissions. The study showed that forced drying to the desired moisture content for processing into final products had considerable contribution to the global warming impact although most drying of the feedstock occurred naturally while drying in the forest before collection. Therefore, use of high-efficiency dryer systems and using field-dried feedstock with lower moisture content would have crucial impact on the overall system sustainability and be necessary to achieve optimal reduction in greenhouse gas emissions.
