Pulps with residual lignin ranging from 6.4-27.4% (w/w) were prepared mixed softwoods using a proprietary biorefining technology (the Lignol process) based on aqueous ethanol organosolv extraction. The pulps evaluated for bioconversion enzymatic hydrolysis of the cellulose fraction to glucose and subsequent fermentation ethanol. All readily hydrolyzed without further delignification. More than 90% in low (< or =18.4% lignin) was 48 h an enzyme loading 20 filter paper units/g cellulose....
The potential of forest-based bioenergy to reduce greenhouse gas (GHG) emissions when displacing fossil-based energy must be balanced with forest carbon implications related biomass harvest. We integrate life cycle assessment (LCA) and analysis assess total GHG over time. Application the method case studies wood pellet ethanol production from reveals a substantial reduction in due production. For all cases, harvest-related reductions associated initially exceed avoided fossil fuel-related...
The use of coal is responsible for 1/5 global greenhouse gas (GHG) emissions. Substitution with biomass fuels one a limited set near-term options to significantly reduce these We investigate, on life cycle basis, 100% wood pellet firing and cofiring in two generating stations (GS) Ontario, Canada. GHG criteria air pollutant emissions are compared current hypothetical natural combined (NGCC) facilities. utilization provides the greatest benefit kilowatt-hour reducing by 91% 78% relative NGCC...
Abstract The production costs of a lignocellulosic ethanol process, both currently and projected for 2020, were compared to corn determine its economic competitiveness. A techno‐economic model was used estimate the current base‐case, 50 ML yr ‐1 softwood facility, as well providing basis cost‐reduction test cases assessing different feedstock, scaling, enzyme, coproduct options. progress ratio indicated that could be competitive with by based on volumes mandated 2007 EISA. However, cost...
Challenges and opportunities for paints coatings.
This research quantifies the economic value of ecosystem services by land cover type, using a case study approach and data localized to southern Ontario, Canada. The cumulative different per unit area can be valuable ecological indicator for guiding use decision-making environmental planning. Literature values were used ascribe provisioning, regulating, cultural, supporting classes. Data describing classification from two time periods understand changes on landscape before after protected...
