Turning crop wastes and
other biomass into charcoal and spreading it on tropical soils can sequester carbon and boost crop productivity
While popular catalysts called zeolites could help turn paper manufacturing waste and
other biomass into fuel, the catalyst crumbles after just two days in hot water.

other biomass into sugars may be applicable to the production of sustainable biofuels,» Professor Lo concluded.
Turning trees, grass, and
other biomass into fuel for automobiles and airplanes is a costly and complex process.

In
other words, «
biomass» describes the mass of all biological organisms, dead or alive, excluding biological mass that has been transformed by geological processes
into substances such as coal or petroleum.
«The idea is to demonstrate that the combination of our pyrolysis and our upgrading technology provides superior economic returns for people who own
biomass and want to turn it
into transportation fuels,» Rekoske says — an effort that could be useful on
other islands or even the U.S. mainland.
Tropical forests convert more carbon from the atmosphere
into biomass than any
other terrestrial ecosystem on Earth.
«Maybe if we can transfer the genetic information to make these oils
into quicker growing organisms like
other algae that grow a lot quicker or a land plant that can produce large amounts of
biomass, we can have them produce oil for us.»
The new analysis found that conventional crops such as corn had the highest yield of
biomass that can be turned
into biofuel on marginal lands, although their ability to reduce CO2 is harmed by tilling, fertilizing and
other CO2 - producing activities necessary to turn them
into fuel.

INTO CHARCOAL Wood or
other biomass heated slowly in a chamber without oxygen will transform
into charcoal that does not decompose for thousands of ye
into charcoal that does not decompose for thousands of years.
When storms, fires, or
other disturbances kill a great number of trees, the dead
biomass is decomposed by fungi, insects, and the like, releasing carbon dioxide
into the atmosphere.
Like its cousins, common forms of algae, cyanobacteria suck in huge amounts of carbon dioxide from the environment and convert it
into other materials, such as
biomass.
Some technologies focus on improved ways of breaking down
biomass for conversion
into fuel, some on engineering plants with the characteristics most advantageous for biofuels, and still
others on creating co-products that can help make advanced biofuels economically viable.
By combining the cellulose - breakdown and sugar - conversion steps, we are very close to a single - step method of converting raw
biomass into a new platform chemical — a chemical you can readily turn
into a transportation fuel or for synthesis of plastics and
other useful materials,» said PNNL geochemist and study coauthor Jim Amonette.
The problem is that the transformation of CO2
into biomass, its absorption by the oceans and all the
other sinks (except for geologic processes that take a VERY long time) is a storage, not a true transformation.
Up to 9 % of the incoming short wave radiation (400 - 700nm) is incorporated
into biomass by photosynthesis, admittedly requiring
other nutrients in optimal abundance.
Converting
biomass into other chemicals is often costly or inefficient, due to the many production steps needed.
When storms, fires, or
other disturbances kill a great number of trees, the dead
biomass is decomposed by fungi, insects, and the like, releasing carbon dioxide
into the atmosphere.
And closer study of
biomass burning is calling
into question the «carbon - neutral» assumption: that growing wood or
other biomass captures the same amount of CO2 that subsequent burning for electricity generation releases.
Instead of sending that CO2 back
into the atmosphere when the
biomass is burned, BECCS facilities capture the emissions and either store them or use them for some
other purpose.
This is because the majority of wood processors today recycle their waste wood off cuts either
into other products or for
biomass, often in replace of fossil fuels.
To date, renewable hydrocarbon - based fuel substitutes have required the complex, multi-step conversion of algal or
other agricultural
biomass feedstocks
into fuel pre-cursors, and subsequent chemical upgrading.
Therefore the production of energy from
biomass releases carbon dioxide
into the air — unlike the use of
other renewable energy sources such as solar or wind.
The main natural sinks are the oceans and plants and
other organisms that use photosynthesis to remove carbon from the atmosphere by incorporating it
into biomass.
This robotic mower uses an electrically driven bar cutter to mow the grass, instead of the standard rotating blade found in most
other mowers, and then feeds the grass
into a pelletizer, producing
biomass pellets that are used in an onboard gasifier to power the device's engine.
In
other words whereas 52 coal fired power stations would meet the average (scenario 2) demand, they will probably need around 200 GW of wind plus PV plus solar thermal plus
biomass - gas - electrical generating capacity, when all energy costs and losses are taken
into account.
We have experience counseling clients through the risks and opportunities, and myriad development, financial, and regulatory documents to comply with green standards, and we assist with incorporating green financial incentives, including renewable energy and
other tax credits (such as wind, solar, and
biomass)
into these programs.
