  • Evaluation of initial collision-attachment efficiency between carbon dioxide bubbles and algae particles for separation and harvesting

    Microalgae have been regarded as a pollutant causing algal blooms in lakes or reservoirs but have recently been considered as a useful source of biomass to produce biofuel or feed for livestock. For the algae particle separation process, carbon dioxide (CO2), one of the main greenhouse gases, is dissolved into a body of water rather than being emitted into atmosphere. This study aims at ...

  • An Overview of Terrestrial Sequestration of Carbon Dioxide: The United States Department of Energy`s Fossil Energy R&D Program

    Abstract Increasing concentrations of CO2 and other greenhouse gases (GHG) in the Earth's atmosphere have the potential to enhance the natural greenhouse effect, which may result in climatic changes. The main anthropogenic contributors to this increase are fossil fuel combustion, land use conversion, and soil cultivation. It is clear that overcoming the challenge of global climate change ...

  • Simple models for carbon assimilation by plants

    The detailed processes in photosynthesis are complicated and hard to model. In many cases, however, it’s possible to simplify the model by focusing on one or more of the limitations to assimilation. Carbon Assimilation Simplified: Light and WaterIn simplest terms, carbon assimilation involves the chemical transformation of carbon dioxide and water to carbohydrate and oxygen within the leaves of ...

  • Gaseous emissions during concurrent combustion of biomass and non-recyclable municipal solid waste

    Abstract Background: Biomass and municipal solid waste offer sustainable sources of energy; for example to meet heat and electricity demand in the form of combined cooling, heat and power. Combustion of biomass has a lesser impact than solid fossil fuels (e.g. coal) upon gas pollutant emissions, whilst energy recovery from municipal solid waste is a beneficial component of an integrated, ...

  • How Carbon Trading Can Help Preserve Coastal Ecosystems

    Introduction The ocean is the largest long-term carbon sink on the planet, storing and cycling 93% of the earth’s CO2 . The ocean’s vegetated habitats, in particular mangroves, salt marshes, and seagrasses, comprise only 0.05% of the plant biomass, but store equal amount of carbon as terrestrial biomass per year, and thus stand among the most ...

  • Double exponential model describes decay of hybrid Bermudagrass thatch

    Empirical modeling helps understand decay processes. The objective of this research was to find a suitable model, and then use it to describe decay of thatch from hybrid bermudagrass [Cynodon dactylon (L.) Pers. x Cynodon transvaalensis Burtt-Davy]. The carbon dioxide–carbon released from ‘Tifdwarf’ and ‘Tifeagle’, each 24 h over 20 d, was plotted as percent C remaining vs. time. Four empirical ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...
