“…The transportation model combined time‐based ($29 hr −1 ) and distance‐based ($0.75 km −1 ) transportation costs, assuming operation of a 28‐megagram (Mg) chip van. Details assumed for chipping and loading costs are provided in Richardson et al . (2011).…”

Bioenergy development can offer beneficial ecological and economic synergies through the expansion of ecological restoration projects. Such synergies are demonstrated by means of a case study conducted in central Washington State, where a 52.4-ha ecological restoration site on the Yakama Reservation generated 34 megagrams (Mg) of invasive tree biomass per hectare, costing $988 ha -1 . A geospatial model of transportation costs estimated that extracted invasive tree biomass can generate revenues throughout 1103 803 ha when delivered to a proposed bioenergy facility in White Swan, Washington, providing 53 000-180 000 Mg of biomass per year for several decades. Thermochemical analyses revealed that the elevated nitrogen, sulfur, and ash content in two prolific invasive trees -Russian olive (Elaeagnus angustifolia) and salt cedar (Tamarix spp) -will limit demand for either of these invasive species. We compare our regional data to national estimates, and show the broader potential for expanding ecological restoration activities and biomass supplies through the revenues generated by the sale of invasive tree wood-waste into bioenergy markets.

“…Residue-to-grain ratios are taken from [58] since they are the most recent and comprehensive and have been derived from empirical research conducted in Ontario (Table 3). Following [38,46], this study takes a conservative approach to residue extraction and assumes that only 30 per cent of theoretically available residues are able to be diverted toward bioenergy production. Residue extraction is restricted to areas that consistently demonstrate yields above 150 bu/ha (150 bu is converted to tonnes in Table 4 for specific crop types) which is considered to be a conservative baseline at which residue removal is sustainable [54].…”

“…In other words, only land identified by the ARI as abandoned or idle is included in the spatial and numerical assessment of potential dedicated energy crop production. Land under hay and fodder corn is also excluded from the study as these crops are economically unavailable in the region due to competing uses in the food industry [56,58] (see also [38]). Residues from soybean production are difficult to harvest and are typically low-yielding in Ontario [58] and are therefore also excluded from the study.…”

“…Increasingly, GIS-based resource assessments are integrating geo-information related to forestry and agricultural activities (e.g., [35][36][37][38][39][40]). In the rare case that this occurs, however, discussions of technological options for bioconversion are generally limited to electricity and heat (but see [39]); and opportunities for synergy between available biomass resource options are not explored.…”

Local bioenergy will play a crucial role in national and regional sustainable energy strategies. Effective siting and feedstock procurement strategies are critical to the development and implementation of bioenergy systems. This paper aims to improve spatial decision-support in this domain by shifting focus from homogenous (forestry or agricultural) regions toward heterogeneous regions-i.e., areas with a presence of both forestry and agricultural activities; in this case, eastern Ontario, Canada. Multiple land-cover and resource map series are integrated in order to produce a spatially distributed GIS-based model of resource availability. These data are soft-linked with spreadsheet-based linear models in order to estimate and compare the quantity and supply-cost of the full range of non-food bioenergy feedstock available to a prospective developer, and to assess the merits of a mixed feedstock stream relative to a homogenous feedstock stream. The method is applied to estimate bioenergy production potentials and biomass supply-cost curves for a number of cities in the study region. Comparisons of biomass catchment areas; supply-cost curves; resource density maps; and resource flow charts demonstrate considerable strategic and operational advantages to locating a facility within the region's -transition zone‖ between forestry and agricultural activities. Existing and emerging bioenergy technologies that are feedstock agnostic and therefore capable of accepting a mixed-feedstock stream are OPEN ACCESS ISPRS Int. J. Geo-Inf. 2014, 3 210 reviewed with emphasis on -intermediates‖ such as wood pellets; biogas; and bio-oils, as well as bio-industrial clusters.
