“…According to the 2016-billion-ton report reference scenario (that assumes low growth in biomass for energy and moderate growth in housing starts), about 84.5 million dry metric tons of forest residues (including biomass from clearcutting harvesting and thinning operations) will be available in 2022 [21]. The WTW project identified a few logistics options, technologies, and processes that utilize these residues for high-value wood-based products that could help offset the forest restoration and fuel reduction treatments costs, while providing rural jobs [9,22,23].…”

This study assessed the environmental impacts and economic feasibility of generating heat using wood-briquettes (WBs), and heat and electricity using torrefied-wood-briquettes (TWBs). WBs and TWBs were manufactured from forest residues using portable systems and delivered to either residential consumers or power plants in the United States. An integrated cradle-to-grave life-cycle assessment (LCA) and techno-economic analysis (TEA) approach was used to quantify environmental impacts and minimum-selling prices (MSPs) of heat and electricity, respectively. Results illustrated that 82% and 59% of the cradle-to-grave global warming (GW) impact of producing heat resulted from the feedstock preparation in WBs and torrefaction in TWBs, respectively. About 46–54% of total cost in the production of heat were from labor and capital costs only. The GW impact of electricity production with TWBs was dominated by the torrefaction process (48% contribution). Capital cost (50%) was a major contributor to the total cost of electricity production using TWBs. The GW impacts of producing heat were 7–37 gCO₂eq/MJ for WBs, and 14–51 gCO₂eq/MJ for TWBs, whereas producing electricity using TWBs was 146–443 gCO₂eq/kWhe. MSPs of generating heat from WBs and TWBs were €1.09–€1.73 and €1.60–€2.26/MJ, respectively, whereas the MSP of electricity from TWBs was €20–€25/kWhe. Considering carbon and pile-burn credits, MSPs of heat and electricity were reduced by 60–90% compared to the base-case.

“…Site improvement or revegetation projects on these lands result in large amounts of the removed woody material (Redmond et al ). This wood waste represents an ideal source material for a soil amendment to aid revegetation because it is already on site, which limits purchase and hauling costs (Sasatani & Eastin ). On‐site sourced amendment applications can include chipping the woody material and either applying the chips on the soil surface or incorporating them into the soil through tilling (Benigno et al ).…”

Amendments, such as woodchips or biochar, may improve success of arid and semi‐arid wildland revegetation limited by unpredictable and insufficient rainfall as well as low soil water holding capacity. In an 116‐day greenhouse experiment simulating a nearby savannah, response to four amendment treatments (no treatment, incorporated biochar, incorporated woodchips, and surface woodchips) was tested across two field soils (Chiricahua and Hathaway) and four simulated precipitation treatments (100, 80, 60, and 40% of average) in a replicated design. Soil type, amendment treatments, and simulated precipitation all had significant (p < 0.01) effects on aboveground biomass. The surface woodchip treatment averaged the highest biomass production of the amendment treatments (489 kg/ha) and the incorporated woodchips had the lowest (298 kg/ha). Aboveground biomass decreased with decreasing precipitation (533, 468, 350, and 216 kg/ha, respectively). Biochar amended soils averaged 5–10% higher volumetric water content than the woodchip amendments and controls through a 28‐day dry down. Microbial nitrogen and phosphorus acquiring activities were higher in Hathaway soils while carbon activities were higher in Chiricahua soils. The surface woodchip treatment resulted in a different species composition than the other amendment and control treatments (p < 0.01). None of the amendment treatments ameliorated low precipitation conditions for plants. Contrary to expectations, carbon and phosphorus exoenzyme activities were highest in the lower precipitation treatments (60 and 40%) and nitrogen exoenzyme activities remained high in Hathaway soils regardless of precipitation. Surface application of woodchips increased vegetation as well as carbon and phosphorus exoenzyme activities while incorporating woodchips suppressed vegetation.
