Evaluation of wood biomass utilization for the greenhouse industry in British Columbia
… greenhouse industry is considering the use of wood biomass, mainly wood pellets and wood residue, to decrease the natural gas demand. However, the long-term economic value, the air quality emission, and the long-term resource availability are the main barriers for the industry to convert into …

Catalystic Pyrolysis for the Production of Stable Phenol Rich Bio-Oil from Wood Biomass
Biomass studies over the last two decades shows its use as an alternate source for the production of chemicals and fuels. This can help in reducing our load on the conventional hydrocarbon use and be shared with renewable sources such as forest and agricultural wastes. In Saskatchewan, there is …

Torrefied-Hydrochar Blend Wood Biomass Improvement for Fuel Pellet Production: A Tree-to-Customer Analysis
… sale in the United Kingdom. This work focuses on wood biomass improvement using dry torrefaction in combination with a hydrothermal carbonization (HTC) binder made from the same feedstock for sale in the United Kingdom at a scale of approximately 100,000 metric tons per year. The primary mode of …

A Biosocial Case Evaluation of Wood Biomass Availability Using Silvicultural Simulations and Owner Intentions on Family Forests in Virginia and North Carolina
Interest in wood-based bio-energy systems in the United States is increasing and may play a part in future renewable energy initiatives (Dincer 2000). Family forests have potential to play an important role in supplying wood biomass for energy production. However, access depends mostly on the …

Differential Protein Expression and Butanol Production using <i>Clostridium beijerinckii</i>
… of butanol using discarded lignocellulose from biomass, specifically wood. The wood biomass (wood chip), is processed by treatment with high temperature and pressure, resulting in a hydrolysate consisting of free sugars and other breakdown products of cellulose and hemi-cellulose. We have been …

The productive reuse of coal, biomass and co-fired fly ash
… increase the worldwide practices of firing biomass and co-firing biomass with coal, which are both considered more sustainable energy sources than coal-only combustion. Reuse options for the by-products of these processes -biomass ash and co-fired fly ash -remain limited. Therefore, this …

Multiple ecosystem services in smallholder agriculture
… livelihoods in the tropics, the production of wood and livestock forage and the structure and fertility of soils were examined in grazed and improved fallows in western Kenya. The objectives were to investigate fine-scale interactions among ecosystem services, and the potential of fallow plant …

Dynamics of water, carbon, and nitrogen in forest and alpine tundra ecosystems in the Pacific Northwest and the Rocky Mountains of the U.S. under future climate change
… are largely affected by a reduction in foliar biomass resulting from severe air temperature and humidity stress to the forest in summer. Projected future decreases in foliar biomass in the old-growth Douglas-fir forest results in 1) decreases in transpiration and increases in summer and fall …
