Abstract:

Bioenergy is the most relevant renewable energy source today. Many technologies and concepts are implemented to provide heat, power and transport fuels. While biomass is a limited resource, so bioenergy provision needs integration, not only in the energy system but also in sustainable supply systems. The use of residual and waste materials will increase and needs mobilisation strategies and utilisation technologies. Due to diﬀerent biomass potentials, energy infrastructure and energy strategies in diﬀerent countries, even under the transformation towards more and more renewable energy-based en

Abstract:

Understanding willingness to harvest (WTH) is essential to assessing the social availability of woody biomass from private land. Currently, the only economically feasible way to harvest woody biomass is in conjunction with sawlogs. We examined WTH sawlogs and woody biomass from owners of family forests using data from a survey of Missouri forest owners. While their WTH increased with revenue expected from woody biomass, revenue expected from sawlogs was a stronger influence. Incentive payments for woody biomass thus are unlikely to increase its supply, and the social availability of woody biom

A comparison is made between the different models of the biomass size spectrum proposed by a number of authors.

The simplest model does not consider the complexities of food webs over food chains, somatic growth, or the continuous nature of the size spectrum. Comparison with the more complex models, however, shows that these omissions do not seriously affect the slope of the size spectrum. For example, one model predicts that the effects of so

Abstract:

Many traditional biological methods for the treatment of wastewater cope poorly with toxic, volatile organic compounds. The extractive membrane bioreactor is a novel process for the treatment of industrial wastewaters containing such compounds which combines extraction across a silicone rubber membrane with biodegradation. Previous work has shown that there is a problem in this system with excess biofilm growth on the membrane surface, resulting in reduced flux of organic substrate across the membrane. The work presented here shows that addition of sodium chloride to the biomedium increases th

Abstract. In the North Atlantic Ocean north of 40∘ N, intense biological productivity occurs to form the base of a highly productive marine food web. SeaWiFS satellite observations indicate trends of biomass in this region over 1998–2007. Significant biomass increases occur in the northwest subpolar gyre and there are simultaneous significant declines to the east of 30–35∘ W. These short-term changes, attributable to internal variability, offer an opportunity to explore the mechanisms of the coupled physical–biogeochemical system.

Abstract:

Roots and rhizomes play diverse roles in the response of coastal wetland ecosystems to climate change through hydrobiogeomorphic and biogeochemical processes. The accumulation of living and dead belowground biomass contributes significantly to surface elevation gain, redox status through root oxygen loss and exudates, and plant transport of greenhouse gases to the atmosphere. Yet, responses of belowground biomass to global climate stressors are difficult to measure and remain poorly understood. Here, we report on the response of individual components of belowground biomass to 12 years of CO2 e

Biomass, due to its neutrality in terms of greenhouse gas emissions into the atmosphere during its life cycle, is considered an interesting renewable source for energy production as an alternative to the use of more polluting fossil fuels.

The aim of this work was to estimate the economic and global warming potential (GWP100a) generated along the thermal energy supply chain of wood pellets, starting from the production of raw biomass from dedicated popla

Although the VAR model did not improve the estimation of bolewood biomass, it significantly improved the estimation of live branch and leaf biomass, and provided less biased estimates of bolebark and current twig weights relative to the CAR model.

Cellulose, hemicellulose, and lignin make up the majority of biomass energy, which is a sustainable and renewable feedstock.

Separating lignin from cellulose in biomass before converting it to biofuels or bioproducts is a crucial pre-treatment step. Alkali acid can be used to extract lignin from non-food components that remain following agricultural processing. As a result, we achieve the required lignin by the above procedure was used.

Abstract:

Abstract Three mature loblolly pine stands in north Louisiana were sampled to determine the dry weight and nutrient content of both the understory hardwoods and the pine biomass that would remain following a conventional harvest. Approximately 52 t/ha of understory hardwoods and 22 t/ha of pine residues were estimated to exist in these stands. Combined, this biomass contained 208, 16, 114, 215, and 40 kg/ha of N, P, K, Ca, and Mg. Potential removal of these quantities in a fuelwood harvest would not appear to greatly diminish soil pools of the same elements. Forest Sci. 32:3-9.

Anaerobic digestion of microalgae and cyanobacteria was first proposed as a destination for algal biomass accumulated on stabilization ponds since it could not be disposed of directly in the environment. Now, the versatility of algal biomass makes them a suitable candidate to produce biofuels and other biomolecules in biorefineries. Anaerobic digestion of biomass is advantageous because it does not require the extraction of specific cellular constituents or drying of the biomass. Nevertheless, challenges remain regarding biomass concentration and their resistant cell walls, which are factors t

The composition of the flue gas consists of combustion products of rice husk which are mainly CO2, CO, N2. A little volatile in the rice husk, which could not burn completely, residual oxygen and dust will fly in airflow. The amount of dust in the outlet gas is a combination of un-burnt amount
