and most energy sources, even others based on biomass, contribute to the problem. That s because, Price said,
burning the biomass releases the carbon back into the atmosphere. By comparison, because there s no combustion in All Power Labs gasification process,
Rather, it is pulled from the biomass and converted into charcoal. Thanks to gasification and the fact that that charcoal can be put back into the ground
One reason for that growth is that dense biomass is everywhere. Think about America s heartland,
And while the system can t convert every form of biomass, Price said that one of the company s biggest aims is to make it possible to use any organic material.
and leaf litter biomass builds up on the forest floor and frequently causes wildfires. In addition many of Madagascar's plants have evolved defenses against large herbivores such as spines
The satellite called BIOMASS will use long range radar to pierce through clouds and collect data from forested regions inaccessible from the ground such as the boreal forests of Russia and the Amazon rain forest.

Ahead of the Thanksgiving holiday 41 leading scientists sent a letter to the U s. Environmental protection agency (EPA) calling on the agency to protect U s. forests from the growing sucking sound created by biomass power plants.
or other plant materials known as biomass to generate electricity. The biomass industry argues that because trees grow back biomass offers a carbon neutral form of energy.
But not all biomass is created equal. Trees are not the same as perennial grasses or harvest residues that can either regrow quickly would otherwise be burned in the field
or are needed not for other purposes. And the latest science reveals that burning whole trees for energy results in more carbon emissions than burning coal for decades.
That's because trees are less energy-dense than coal and harvesting them for fuel means foregoing the carbon they would have absorbed from the atmosphere if left standing.
The agency issued to biomass-burning plants a three-year exemption from permitting requirements under the Clean Air Act (basically a requirement that each new and modified industrial source gets a construction permit before starting to build showing that it will use the best available control
and could result in regulations that distort the marketplace towards greater use of unsustainable sources of biomass with significant risks to our climate forests

where forests contain less biomass, says co-author Greg Asner, a scientist with the Carnegie Institution of Science in Stanford, California.
Now people are moving north and west into the higher biomass forests. The results underscore the danger posed by deforestation,
We have to monitor biomass, he says. Driven in large part by agriculture, deforestation in the Amazon averaged about 1. 6 million hectares annually from 2001 to 2007,
who in 2007 produced the most comprehensive biomass maps of the Amazon. We were surprised that nobody had done this before,
Saatchi says that earlier biomass maps had only coarse resolution and were often based on models.
They then extrapolated to build a biomass map of the Amazon basin circa 2000; the results were published in Global Change Biology. 2 It basically provided a benchmark map of the biomass carbon in the Amazon,
Saatchi says. He calls the Carnegie analysis very simple and neat and says his team is conducting a similar analysis on the impacts of fire.
The researchers behind the study say that biomass production for fuel or electricity generation will have the biggest impact on landscape and habitats.

Satellites beam in biomass estimates: Nature Newswhatever agreement emerges from the climate meeting in Copenhagen,
the first satellite-based estimates of the biomass contained in the world's tropical forests. Current biomass estimates for the tropics are gathered based on data by the Food and agriculture organization of the united nations (FAO),
and their quality varies greatly from country to country. As a result, baseline figures for biomass are some of the biggest uncertainties in calculating emissions from deforestation and forest degradation,
recently estimated to be around 15%of global carbon emissions (G r. van der Werf et al. Nature Geosci. 2, 737-738;
But Saatchi says that the study provides additional information about biomass levels at regional and national levels.
You need to know how biomass is distributed and how it's changing over time, almost everywhere, with some resolution and accuracy.
Also at Copenhagen, researchers at the Woods Hole Research center in Massachusetts presented another pantropical biomass assessment,
Richard Houghton, a biomass expert at Woods Hole says that it is good news that multiple teams are tackling the big-picture question of tropical forest biomass.
We need a couple of independent estimates just to see how well they match, he says. Anybody can make a map.
Asner has developed also a system for assessing biomass at finer resolution, which will be necessary if forests are going to be linked to international carbon markets.
The new pantropical biomass maps from Saatchi and Woods Hole won't accomplish that goal, but they can provide scientists and policy-makers with a better understanding of carbon trends.
Asner has found that deforestation in Brazil is moving into higher biomass areas in the interior of the forest.

Oregon, could eventually sequester 9 million tonnes of carbon in their combined biomass. He compares it to planting trees.
and accumulate that as biomass. Whales take carbon out of the system through their food,
there could still be a substantial increase in total biomass owing to the difference in size between whales
any given food source (such as krill) can support a lot more biomass in a whale than in a small animal such as a penguin.
And even though all of these animals'biomass combined represents a small fraction of total human carbon emissions,
The large Brazilian ethanol producer ETH Bioenergia announced on 18 february that it would take over the debt-ridden Brazilian Renewable Energy Company (Brenco) to create a world-leading company to make ethanol from biomass.
adds that Chinese farmers could also leave dead crop biomass on the fields to help rebalance the soil.
but ground data provides clear evidence of biomass loss and an increase in tree deaths.
The change in the growing season may mean there is less grassland biomass available for grazing says Xu.
Cellulosic ethanol producers are trying to generate fuel from biomass such as leaves and branches. These feedstocks have the advantage that they are plentiful
Like most forests, peat-swamp forests store large amounts of carbon above ground as biomass
Koh and his colleagues calculate that this conversion led to the release of about 140 million tonnes of carbon from biomass above ground
The 9 may study examined the future of six renewable energy sources (biomass, hydro, wind, solar, geothermal and oceans).

and transporting the biomass. Scalability remains the big problem: people have farmed seaweed for hundreds of years,
biomass stoves, brick kilns and coke ovens. Other measures would reduce the burning of agricultural waste
and biomass maps to model the change. The difference is in large part due to a natural lag as carbon stocks slowly decay
A direct conversion of that lost biomass into carbon would suggest a drop in annual carbon dioxide emissions from more than 1. 1 billion tonnes of CO2 in 2004 to 298 million tonnes of CO2 a reduction of nearly 74%.
and aerial studies to create more accurate maps of forest biomass, which can then be used to calculate emissions.

dried grasses and other indigestible plant matter could greatly improve the efficiency of converting waste biomass to fuel.
But most of the biomass produced in agriculture and forestry lies unused in more-complex chains of sugars, for example lignin and cellulose.
"I think there is a great potential for this approach in biomass processing, says Harvey Blanch, a bioenergy researcher at the Joint Bioenergy Institute in Emeryville, California,
director of biomass applications at enzyme company Novozymes, based in Raleigh-Durham, North carolina. But Luterbacher says that his team's enzyme-free process has plenty of potential for improvement."
By contrast, GVL is made easily from biomass, and easily recovered from a mixture of dissolved sugars.
or applying extremely high temperatures to break down biomass into syngas (hydrogen and carbon monoxide). Claire Curry, a bioenergy analyst at the information firm Bloomberg New Energy Finance, expects that some 50 million to 60 million gallons of cellulosic ethanol could be produced commercially worldwide this year up from just a few
Tapping the storehouse of biomass left after the harvest is much less controversial. Ethanol made from corn stover produces at least 60%less greenhouse-gas emissions than petrol,
The process requires the biomass to be ground up and pretreated with acids. A cocktail of enzymes must then be applied to chop up the tough biological polymers inside all before the yeast is added to the resulting sugars.
In a new program the U s. Forest Service is fueling a biomass power plant in Colorado with trees killed by a pest called the mountain pine beetle Greenwire reports.
Supporters say the beetle trees-to-biomass program is environmentally friendly but not all groups agree.
Biomass power plants do use a renewable fuel but nevertheless contribute to global warming because they put greenhouse gases into the atmosphere.
Some environmental groups such as the council are worried also about the Forest Service encouraging logging for biomass plants.
Forest biomass currently comprises about 75 percent of global biofuel production. The study appears in the journal Global Change Biology-Bioenergy.
Formed from the incomplete combustion of fossil fuel biofuel and biomass it is emitted directly into the atmosphere
The area currently has little vegetation biomass due to heavy degradation but has an excellent climate for tree growth
and cool because highly flammable dead biomass is allowed not to accumulate for many years at a time. This gives animals ample escape routes
and the carbon contained therein was transported into the microbial biomass. For these kinds of residues we can give the all-clear signal
and therefore valuable supplies of biomass across the globe by reducing the need for biofuels Based on our analysis this freeing up of biomass is one of the key system-wide consequences of electrifying transport says Mccollum.
Available biomass could then be used for example in plastics manufacturing or steel production which are otherwise challenging to decarbonize.
rdenas head of the Project said that the intention is to implement a permanent monitoring system with the help of satellite images to quantify the biomass
The specialist at Centro Geo indicated that satellite images allow to monitor different biophysical variables including forest biomass.
rdenas explained that currently the most popular method for measuring trees biomass is by field sampling by the Forest National Commission

However the expected long-term and larger market for Miscanthus is in digesting the celluloses in the biomass to sugars for fermentation to ethanol
If the stand has experienced high mortality caused by bark beetles it can be thinned more heavily without sacrificing timber biomass or volume increment and plant diversity.
Teasing apart the complex relationship between soil fungi and plants is likely to have an impact on improving biofuel production from plant biomass.
One-year-old wheat straw and new hay had the lowest levels of weed biomass compared with new wheat straw and the no-mulch control.
The experiments also proved that the thickness of the mulch affected weed control with mulches applied in two layers resulting in significantly less weed biomass than those applied in one layer.
and sent them to 289 preselected forest plots to measure the number of trees tree girth and biomass per hectare.
and equipment community members with limited education can accurately monitor forest biomass--previously thought to be the domain of highly-trained professionals.

The researchers determined that strawberry biomass nitrogen accumulation showed a consistent pattern across fields with limited N accumulation from fall transplanting through March followed by a consistent rate of crop N uptake through the rest of the production season.
Up until now it has been underutilised as a biomass residue and waste material. These were the conclusions of a study conducted by the TLL (Thueringian regional institute for agriculture) the DBFZ (German biomass research center) and the Helmholtz Center for Environmental Research (UFZ.
According to them from a total of 30 million tons of cereal straw produced annually in Germany between 8 and 13 million tons of it could be used sustainably for energy or fuel production.
Enhancing expression of these genes resulted in vastly increased oil content in leaves the most abundant sources of plant biomass-a finding that could have important implications for increasing the energy content of plant-based foods and renewable biofuel feedstocks.
The idea behind Xu's studies was to find a way to reprogram plants to store oil in their more abundant forms of biomass.
Burning plant biomass with such energy density to generate electricity would release 30 to 40 percent more energy
and the nutritional value of feed made from such energy-dense biomass would also be enhanced greatly.
Xu is now collaborating with Brookhaven biochemist John Shanklin to explore the potential effect of overexpressing these key genes on oil production in dedicated biomass crops such as sugarcane.
and because the total biomass of animals is vastly lower than the plants that they rely upon
And these indirect effects can be quite huge--and disproportionate to the biomass of the species that are instigating the change.
Genetically enhanced tobacco could be an alternative source of biomass in areas like Extremadura and Andalusia the traditional tobacco producers.
or wheat As cereals are currently being used as the raw material to produce bioethanol genetically enhanced tobacco could be an alternative source of biomass
and phosphorus in the soil and has increased rhizome production and aboveground biomass which in turn facilitates its spread and establishment.
But now there is a lot of interest in using sorghum for other things such as growing sweet sorghum in areas where they grow sugarcane and growing biomass sorghum for bioenergy through combustion or cellulosic technology.
and use the genes that we bred for in grain sorghum over the last hundred years and move them into sweet sorghum and biomass sorghum.
or biomass sorghum researchers will need to bring in some of the genes from grain sorghum for traits like seed quality or early-season vigor.
But the bigger problem with biomass sorghum right now is the moisture content of the biomass.
Because biomass sorghum is grown annually growing until frost comes when it is harvested it has a high moisture content.
When we cut it down there's tons of biomass. I don't know that there's anything else that can match it in the area
but the biomass is really high moisture. For the existing cellulosic idea as it stands now that is not very useful he said That's one of the roadblocks to biomass sorghum right now he said.
Sweet sorghum where you squeeze the sugary juice out like sugarcane may be closer on the horizon.
In addition to his work on the bordered pits in wood Goodell works in the area of advanced engineered composites fabrication and in biomass bioconversion.
which some day may be used in biomass conversion processes for energy and sustainable biomaterials production. His study of the brown rot fungi led him to study tree defenses at the nanostructure scale.
Using a new satellite-based vegetation monitoring system researchers found that about 12 percent of the biomass has disappeared in this country that's more than twice the size of Texas
Related research has found that heavy grazing results in much less vegetation cover and root biomass and an increase in animal hoof impacts.
%The team also determined that at most of the sampling points the oil content in the biomass of the male tree was greater than that in the biomass of the female tree.
#Sharing the risks/costs of biomass cropsfarmers who grow corn and soybeans can take advantage of government price support programs
but similar programs are not available for those who grow biomass crops such as Miscanthus. A University of Illinois study recommends a framework for contracts between growers
The current biomass market operates more along the lines of a take-it -or-leave-it contract
and promote a more sustainable stable biomass supply a new kind of contract needs to be created said Jody Endres a U of I professor of energy and environmental law.
If we get these considerations into the contracts those who finance this new biomass crop industry will have more certainty to invest.
The study identifies considerations that should be included in the framework for a biomass contract including a control for moral hazard risk incentive tradeoff existing agricultural practices
The perennial nature of biomass crops also makes developing contracts challenging. We're in a unique environment
Crop insurance is not currently available for farmers who grow biomass crops so they take on additional risk.
and do not want to be locked into a multi-year contract with a lessee to grow a perennial biomass crop.
although sustainability requirements are important having an adequate supply of biomass is important as well. We're trying to envision a future in
which we have a lot of biomass and one way to secure that is to recognize all of the risks
A newly forming biomass standards group in which Endres holds a leadership role is looking at how the value of sustainability practices can be measured at the watershed eco-shed or air-shed level rather than on the scale of individual farms.
