“…These new revenues could foster the creation of context-driven sustainable solutions aligned with local social, environmental and economic characteristics, using an integrated biorefinery approach [49][50][51][52][53][54]. Looking at an integrated value chain, ethanol production from willow represents a real opportunity for CO 2 reduction depending on the carboneutrality of the electricity grid [55]. Lower selling prices for biomass and new potential revenue streams could foster the development of other valorization streams, such as bioproducts or secondary metabolites for willow phytofiltration biomass to fit integrated biorefinery [11].…”

Wastewater treatment is a necessary step to avoid environmental impacts of water consumption and usage. Traditional approaches are expensive and are limited to developed countries. Phytofiltration using fast-growing trees and shrubs like willows potentially offer an alternative. This paper aims to determine if wastewater treatment using phytofiltration can provide complementary environmental and economic benefits for rural communities in a Nordic climate such as the province of Québec, Canada. It looks at different perspectives of the wastewater treatment solution in a local and rural context. Based on life cycle analysis (LCA) and life cycle cost analysis (LCC), we found that, for an exemplar Québec municipality, the conventional wastewater treatment scenario impacted more on climate change, ecosystem quality and human health than the two phytofiltration of wastewater scenarios studied, where impact is highly dependant on the biomass valorization. The net present cost of the phytofiltration scenarios were lower than typical conventional treatment in Québec. For a biomass producer, conventional biomass production had the highest environmental impact on ecosystem quality, while biomass production from phytofiltration had the highest environmental impact on climate change, human health, and resources. We demonstrate that the phytofiltration is a viable and multifunctional technology that could provide good incentives for a local biomass value chain. it allows to both alleviate wastewater treatment burden and provide affordable biomass for bioenergy development for rural communities. Mobilizing local stakeholders will be key to make phytofiltration an alternative solution for both environmental burden alleviation and rural economic development.

“…Ethylene can also be produced from biomass via ethanol dehydration. , Most of the ethanol produced in the United States is from corn grains, but a promising low carbon pathway for ethanol is from agricultural residues, such as corn stover, or dedicated energy crops, such as poplar wood. Ethanol produced from these materials is referred to as cellulosic ethanol, and it has been shown that this can be a carbon-neutral, or nearly carbon-neutral, fuel. , In 2019, 142.7 billion gallons of motor gasoline were consumed in the United States. According to the current regulation, the maximum percentage of ethanol in motor gasoline is 10%, reaching an ethanol “blend wall” of 14.3 billion gallons.…”

We describe a novel route for producing alkenes and cycloalkanes via the oligomerization of ethylene with a novel Ni-SIRAL catalyst. We report the production of liquid products (ambient conditions) at 50, 100, and 200 °C with subcritical and supercritical ethylene using Ni-SIRAL catalysts with nickel loadings varying from 0.4 to 6.9 wt %, operating at both single-and dualreactor configurations. The highest liquid yield, 43 wt %, with a single reactor, was obtained at supercritical conditions (65 bar), at 200 °C, with a nickel loading of 2.8%. Under supercritical conditions, at 200 °C, the liquid yield increased from 43 to 80 wt % after the addition of a second oligomerization reactor using the Ni-SIRAL catalyst with 2.8 wt % nickel. The ethylene oligomerization under subcritical conditions (40 bar) led to a much lower yield for liquid products than the yield obtained at supercritical conditions at both reactor configurations (single and dual). The dual-reactor configuration proved to be the better configuration for the production of cycloalkanes, with a yield of 7 wt % at subcritical conditions and 10 wt % at supercritical conditions. We proposed a reaction pathway consistent with the experimental data.

“…This can aid in better understanding of climate impacts of bioenergy as biomass systems capture and emit carbon at different points in time. Several LCA studies have assessed Salix cultivation for bioenergy utilization [17,32,33,[36][37][38][39][40]. However, studies looking at the magnitude of impact of differences between Salix varieties on the overall bioenergy system are rare.…”

Short-rotation coppice (SRC) Salix plantations have the potential to provide fast-growing biomass feedstock with significant soil and climate mitigation benefits. Salix varieties exhibit significant variation in their physiological traits, growth patterns and soil ecology—but the effects of these variations have rarely been studied from a systems perspective. This study analyses the influence of variety on soil organic carbon (SOC) dynamics and climate impacts from Salix cultivation for heat production for a Swedish site with specific conditions. Soil carbon modelling was combined with a life cycle assessment (LCA) approach to quantify SOC sequestration and climate impacts over a 50-year period. The analysis used data from a Swedish field trial of six Salix varieties grown under fertilized and unfertilized treatments on Vertic Cambisols during 2001–2018. The Salix systems were compared with a reference case where heat is produced from natural gas and green fallow was the land use alternative. Climate impacts were determined using time-dependent LCA methodology—on a land-use (per hectare) and delivered energy unit (per MJheat) basis. All Salix varieties and treatments increased SOC, but the magnitude depended on the variety. Fertilization led to lower carbon sequestration than the equivalent unfertilized case. There was no clear relationship between biomass yield and SOC increase. In comparison with reference cases, all Salix varieties had significant potential for climate change mitigation. From a land-use perspective, high yield was the most important determining factor, followed by SOC sequestration, therefore high-yielding fertilized varieties such as ‘Tordis’, ‘Tora’ and ‘Björn’ performed best. On an energy-delivered basis, SOC sequestration potential was the determining factor for the climate change mitigation effect, with unfertilized ‘Jorr’ and ‘Loden’ outperforming the other varieties. These results show that Salix variety has a strong influence on SOC sequestration potential, biomass yield, growth pattern, response to fertilization and, ultimately, climate impact.
