“…Previous studies have used a wide range of delivered biomass prices depending on species and geographic locations (i.e., [14,33,[44][45][46]). We considered five biomass price values ranging from 35 to 55 $·t −1 increasing every 5 $.…”

This study used a spatially-explicit model to identify the amount and spatial distribution of economically feasible sites for establishing dedicated energy crops under various market and policy scenarios. A sensitivity analysis was performed for a biomass market with different discount rates and biomass prices as well as policy scenarios including propriety tax exemption, carbon offset payments, and the inclusion of farmland for biomass production. The model was applied to a four-county study area in Kentucky representing conditions commonly found in the Ohio River Valley. Results showed that both biomass price and discount rate have a can strongly influence the amount of economically efficient sites. Rising the biomass price by 5 $·t −1 and lowering discount rate by 1% from the baseline scenario (40 $·t −1 and 5%) resulted in an over fourteen fold increment. Property tax exemption resulted in a fourfold increase, a carbon payment on only 1 $·t −1 caused a twelve fold increase and extending the landbase from marginal land to farmland only slightly increase the economically efficient sites. These results provide an objective evaluation of market and policy scenarios in terms of their potential to increase land availability for establishing dedicated energy crops and to promote the bioenergy industry.

“…102 In the United States, the annual production of dry woody biomass from waste (14 million tons), mills (87 million tons), and harvest residues (64 million tons) is just a fraction of the total amount of lignin available. 103 For example, a joint study by the US Departments of Energy and Agriculture estimate the maximum amount of dry woody biomass that can be annually produced in a sustainable manner from forestlands (368 million tons) and agricultural lands (998 million tons) exceeds 1 billion tons. 104 Due to the projected availability of lignin, ''woody biomass is anticipated to be an important component of any future renewable energy portfolio.…”

This highlight discusses the recent progress aimed at maximizing the potential of biomass for commodity monomers and polymers. These efforts are no longer solely academic issues. In recent years, a variety of alkene, diene, aromatic, and condensation type monomers have utilized renewable resources, such as cellulose, lignin, plant oils, starches, and monoterpenes in commercial polymers. Generally, these multifaceted efforts involve pretreatment of biomass with thermal, chemical, or physical methods followed by a catalyst sequence that entails a combination of acid-catalysis, bio-catalysis, or metal-based catalysis. In this regard, synthesis strategies for ethylene, propylene, a-olefins, methylmethacrylate, 1,3-butadiene, 1,3-cyclohexadiene, isoprene, 1,3-propanediol, 1,4-butanediol, and terephthalic acid are discussed as well as opportunities for other renewable-based monomers.

“…To meet changes in global market competition, private forest land holders are shifting rapidly from extensive forestry to intensive forestry [1,4,5]. Concomitantly, what was traditionally left as biomass residue following either pre-commercial and commercial thinnings or regeneration harvests, are now under consideration as further streams of revenue and bioenergy from the burgeoning "green economy" [6]. The primary question for private forest land holders then becomes, how does intensive forestry, and perhaps utilization of harvest "waste" for bioenergy, affect long-term soil-site productivity and thus long-term net revenue?…”

Biomass harvesting for energy production and forest health can impact the soil resource by altering inherent chemical, physical and biological properties. These impacts raise concern about damaging sensitive forest soils, even with the prospect of maintaining vigorous forest growth through biomass harvesting operations. Current forest biomass harvesting research concurs that harvest impacts to the soil resource are region-and site-specific, although generalized knowledge from decades of research can be incorporated into management activities. Based upon the most current forest harvesting research, we compiled information on harvest activities that decrease, maintain or increase soil-site productivity. We then developed a soil chemical and physical property risk assessment within a geographic information system for a timber producing region within the Northern Rocky Mountain ecoregion. Digital soil and geology databases were used to construct geospatially explicit best management practices to maintain or enhance soil-site productivity. The proposed risk assessments could aid in identifying resilient soils for forest land managers considering biomass operations, policy makers contemplating expansion of biomass harvesting and investors deliberating where to locate bioenergy conversion facilities.
