Effects of Forest Fuel Production Strategies on GHGEmissions in Bioenergy Generation
Short Introductive summary
This study investigates the carbon and energy balance of forest fuel production, handling, and storage strategies using logging residues (LR) for domestic heat generation in Sweden. The aim was to evaluate the impact of various supply chain practices on greenhouse gas (GHG) emissions, particularly CO2, and to identify strategies for minimizing dry matter losses (DML). Thirteen different supply systems were modeled, incorporating variations in storage time, sieving of chips into an accept fraction (chips with larger piece size and with high storability) and reject fraction (fines with low storability), and covering storage piles of LR and wood chips. The analysis considered emissions from machine operations (incl. transportation of chips), storage DML, and combustion, using both higher-and lower heating values. Results indicated that combustion was the primary source of emissions, accounting for approximately 93% of total emissions, while storage and machine operations contributed 6% and 1%, respectively. Significantly, systems implementing sieving and covering of accept fractions showed reduced storage emissions compared to business-as-usual strategies.
