What is an anaerobic lagoon?
to the E.P.A., an anaerobic lagoon is a deep impoundment, essentially free of dissolved oxygen, that promotes
anaerobic conditions. The process typically takes place in deep earthen basins, and such ponds are used as anaerobic pretreatment systems.
Anaerobic lagoons are not aerated, heated, or mixed.
The typical depth of an aerated lagoon is greater than eight feet, with greater depths preferred.
Such depths minimize the effects of oxygen diffusion from the surface, allowing anaerobic conditions to prevail. In
this respect, anaerobic lagoons are different from shallower aerobic or facultative lagoons,
making the process analogous to that experienced with a single-stage unheated anaerobic digester, except that
lagoons are in an an open earthen basin. Moreover, conventional digesters are typically used for sludge stabilization in a treatment process, whereas lagoons typically are used to pre-treat raw wastewater. Pretreatment includes separation of solids that will settle, digestion of solids, and treatment of the liquid portion.
lagoons are typically used for two major purposes:
1) Pretreatment of high strength industrial wastewaters.
2) Pretreatment of municipal wastewater to allow preliminary sedimentation of suspended solids as a pretreatment process.
Anaerobic lagoons have been especially effective for pretreatment of high strength organic wastewaters.
Applications for anaerobic lagoons include industrial wastewaters and rural communities that have a significant organic load from industrial sources.
Biochemical oxygen demand (BOD) removals up to 60% are possible. The effluent cannot be discharged due to the high level of anaerobic byproducts remaining.
are not applicable to many situations because of large land requirements, sensitivity to environmental
conditions, and objectionable odors. Furthermore, the anaerobic process may require long retention times, especially in cold climates, as anaerobic bacteria are not effective below 15° C. As a result, anaerobic lagoons are not widely used for municipal wastewater treatment in northern parts of the United States.
An anaerobic lagoon is a deep earthen basin with sufficient volume to permit sedimentation of solids that will settle, to digest retained sludge, and to anaerobically reduce some of the soluble organic substrate.
Raw wastewater enters near the bottom of the pond and mixes with the active microbial mass in the sludge blanket. Anaerobic conditions prevail except for a shallow surface layer in which excess undigested grease and scum are concentrated. Sometimes aeration is provided at the surface to control odors.
impervious crust that retains heat and odors will develop if surface aeration is not provided. The
discharge is located near the side opposite of the influent. The effluent is not suitable for discharge to
receiving waters. Anaerobic lagoons
are followed by aerobic or facultative lagoons to provide required treatment.
anaerobic lagoon is usually preceded by a bar screen and can have a Parshall flume with a flow
recorder to determine the inflow to the lagoon. A cover can be provided to trap and collect the methane
gas produced in the process for use elsewhere, but this is not a common practice.

An anaerobic digester is a system that takes an organic waste stream and through the process of anaerobic digestion (meaning without oxygen), microorganisms break-down the waste stream which generates biogas in the process. The biogas cannot be used due to the large amount of impurities it contains, so the biogas must cleaned through a biogas to biomethane process after which, the clean biomethane, often referred to as "renewable natural gas" is used just as natural gas, methane or CH4.
The right anaerobic digester and "feedstock" are critical components to optimum production of biomethane which can fuel your own cogeneration or trigeneration power plant.
there are many different types of anaerobic
digesters, three designs (below) are the most common found in the
U.S., which are:
1. Anaerobic Lagoons
2. Plug Flow Digesters
3. Complete Mix Digesters
Anaerobic digestion is the bacterial decomposition of organic waste in the absence of oxygen. The two main products of anaerobic digestion are biogas and a solid residual material.
Food scraps, manure, biosolids, as well as Fats, Oil, and Grease (FOG) can all be "digested" anaerobic digesters and the biomethane (cleaned-up and purified biogas) used to fuel a cogeneration power plant.
Benefits of an Anaerobic Digester:
Food and other organic materials disposed of in landfills decompose to create methane, a lethal greenhouse gas with a global warming potential that is 21 times greater than carbon dioxide. Diverting food scraps from landfills to anaerobic digesters reduces methane emissions from landfills.
Fats, Oil, and Grease (FOG) accumulate and can clog pipes and pumps both in the public sewer lines as well as in wastewater treatment facilities. Diverting FOG from the wastewater infrastructure to anaerobic digesters prevents combined sewer overflows (CSO), thereby protecting water quality and saving money.
Anaerobic digesters provide a management method for manure that; improves the quality of water, improves air quality, reduces methane emissions from manure lagoons and storage ponds and minimizes odors.
Using the solid residual as a soil amendment can reduce the need for chemical fertilizers, improve plant growth, reduce soil erosion and nutrient run-off, alleviate soil compaction, and help improve soil water retention.
How Anaerobic Digesters Produce Biomethane:
The Greenest of all Biofuels!
Anaerobic Digesters recover valuable biomethane from animal manure through a process called anaerobic digestion. The following information highlights the process of how Anaerobic Digesters work.
Biomethane and Anaerobic Bacteria
Biomethane or "Renewable Natural Gas" is practically the same as is a gas that contains molecules of methane with one atom of carbon and four atoms of hydrogen (CH4 ). It is the major component of the "natural" gas used in many homes for cooking and heating. It is odorless, colorless, and yields about 1,000 British Thermal Units (Btu) [252 kilocalories (kcal)] of heat energy per cubic foot (0.028 cubic meters) when burned.
or methane, is a fossil fuel - was created hundreds of thousands of years ago by the anaerobic
decomposition of organic materials (primarily algae). It is often found in association with oil
same types of anaerobic bacteria that produce natural gas also produce biomethane
today. Anaerobic bacteria are some of the oldest forms of life on
earth. They evolved before the photosynthesis of green plants released large
quantities of oxygen into the atmosphere. Anaerobic bacteria break down or
"digest" organic material in the absence of oxygen and produce
as a waste product. (Aerobic decomposition, or composting, requires large
amounts of oxygen and produces heat.)
decomposition occurs naturally in swamps, water-logged soils and rice fields,
deep bodies of water, and in the digestive systems of termites and large
animals. Anaerobic processes can be managed in a "digester" (an
airtight tank) or a covered lagoon (a pond used to store manure) for waste
treatment. The primary benefits of anaerobic digestion are nutrient recycling,
waste treatment, and odor control. Except in very large systems, biomethane
production is a highly useful but secondary benefit.
produced in anaerobic digesters
consists of methane (50%–80%), carbon dioxide
(20%–50%), and trace levels of other gases such as hydrogen, carbon monoxide,
nitrogen, oxygen, and hydrogen sulfide. The relative percentage of these gases
depends on the feed material and management of the process. When
burned, a cubic foot (0.028 cubic meters) of
yields about 10 Btu
(2.52 kcal) of heat energy per percentage of methane composition. For example,
composed of 65% methane yields 650 Btu per cubic foot (5,857
decomposition is a complex process. It occurs in three basic stages as the
result of the activity of a variety of microorganisms. Initially, a group of
microorganisms converts organic material to a form that a second group of
organisms utilizes to form organic acids. Methane-producing (methanogenic)
anaerobic bacteria utilize these acids and complete the decomposition process.
variety of factors affect the rate of digestion and Biomethane
most important is temperature. Anaerobic bacteria communities can endure
temperatures ranging from below freezing to above 135° Fahrenheit (F) (57.2°
Centigrade [C]), but they thrive best at temperatures of about 98°F (36.7°C) (mesophilic)
and 130°F (54.4°C) (thermophilic). Bacteria activity, and thus
production, falls off significantly between about 103° and 125°F (39.4° and
51.7°C) and gradually from 95° to 32°F (35° to 0°C).
the thermophilic range, decomposition and biomethane
production occur more
rapidly than in the mesophilic range. However, the process is highly sensitive
to disturbances, such as changes in feed materials or temperature. While all anaerobic digesters
reduce the viability of weed seeds and disease-producing
(pathogenic) organisms, the higher temperatures of thermophilic digestion result
in more complete destruction. Although
operated in the mesophilic
range must be larger (to accommodate a longer period of decomposition within the
tank (hydraulic retention time), the process is less sensitive to upset or change in
optimize the digestion process, anaerobic digesters
must be kept at a
consistent temperature, as rapid changes will upset bacterial activity. In most
areas of the United States, digestion vessels require some level of insulation
and/or heating. Some installations circulate the coolant from their
engines in or around the digester to keep it warm, while others burn part of the
heat the digester. In a properly designed system, heating
generally results in an increase in
production during colder periods.
The trade-offs in maintaining optimum digester temperatures to maximize gas
production while minimizing expenses are somewhat complex. Studies on digesters
in the north-central areas of the country indicate that maximum net
production can occur in
maintained at temperatures as low as 72°F
factors affect the rate and amount of biomethane
output. These include pH,
water/solids ratio, carbon/nitrogen ratio, mixing of the digesting material, the
particle size of the material being digested, and retention time. Pre-sizing and
mixing of the feed material for a uniform consistency allows the bacteria to
work more quickly. The pH is self-regulating in most cases. Bicarbonate of soda
can be added to maintain a consistent pH; for example, when too much
"green" or material high in nitrogen content is added. It may be
necessary to add water to the feed material if it is too dry or if the nitrogen
content is very high. A carbon/nitrogen ratio of 20/1 to 30/1 is best.
Occasional mixing or agitation of the digesting material can aid the digestion
process. Antibiotics in livestock feed have been known to kill the anaerobic
bacteria in digesters. Complete digestion, and retention times, depend on all of
the above factors.
Sludge or Effluent
material drawn from the anaerobic digester is called sewage
sludge, or effluent.
It is rich in nutrients (ammonia, phosphorus, potassium, and more than a dozen
trace elements) and is an excellent soil conditioner. It can also be used as a
livestock feed additive when dried. Any toxic compounds (pesticides, etc.) that
are in the anaerobic digesters'
feedstock material may become concentrated in the effluent.
Therefore, it is important to test the effluent before using it on a large

digester. The material moves through the digester either mechanically or by the
force of the new feed pushing out digested material. Unlike batch-type
digesters, continuous digesters produce biogas without the interruption of
loading material and unloading effluent. There are three types of continuous
digesters: vertical tank systems, horizontal tank or plug-flow systems, and
multiple tank systems.

growing number of these operations are placing floating covers on their lagoons
to capture the biogas. They use it to run an engine/generator to produce

and the associated "balance of
plant" can vary widely. Systems can be put together using
off-the-shelf materials. There are also a few companies that build system
components. Some sophisticated systems have been designed by professionals whose
major focus is research, not low cost.
Before you install one or more anaerobic digesters on your farm or ranch, food processing plant, or facility, you should explore its economic value and potential benefits. You will also want to consider an anaerobic digester "feasibility study" that specifically reviews your operation and requirements.
digester usually requires manure from more than 150 large animals to
cost effectively generate electricity. The anaerobic
digester and associated biogas production
can also reduce overall operating costs where costs are high for sewage,
agricultural, or animal waste disposal, and the effluent has economic value.
In the United States, the availability of inexpensive fossil fuels has limited the use of digesters solely for biogas production. However, the waste treatment and odor reduction benefits that anaerobic digesters provide are receiving increasing interest, especially for large-scale livestock operations such as dairies, feedlots, and slaughterhouses.
Multiple Environmental and Economic Benefits for Installing Anaerobic Digesters:
Anaerobic digesters generate numerous economic and environmental dividends:
practically free Biomethane (also
referred to as Renewable Natural Gas)
from waste streams. The Biomethane
can then be used as fuel for an onsite power plant such as a cogeneration
or trigeneration power plant.
the free Biomethane
onsite to produce "green energy" qualifies your facility for
additional revenue streams in the form of a Renewable
Energy Credit, Carbon
Dioxide Credits and/or other Greenhouse
Gas Emissions credits.

in nitrogen in wastewater by over 50%
in phosphorous in wastewater by over 50%
and significant reductions of odors, pollution of surface and groundwaters
and nutrient runoff from dairy farms (and other Concentrated Animal Feeding
Operations), wastewater treatment plants.
Better neighbors.... facilities that have installed Anaerobic Digesters have fewer complaints from their neighbors as a result of the reduction or elimination of odors.

What is FOG?
FOG stands for “Fats, Oils and Grease.” FOG is generated in homes and businesses, including anywhere there is a kitchen, cooking, restaurant, animal operation, wastewater treatment plant, car dealership or where machinery and heavy equipment operate.
Many of the foods we eat contain FOG, including; meats, sauces, vegetable oils, salad dressings, deep-fried food (chicken, french fries, fish, etc.), cookies, pastries, butter and many others.
Animal fats and food scraps that go down a sink contribute to FOG problems in sewers. FOG accumulations in the city's sewer system causes obstruction by constricting flow of the sewer pipes, and interfering with the normal operation of your community wastewater treatment system.
FOG is a community problem!
FOG is a major community problem as well as a health hazard from the standpoint of sewage collection, transmission and treatment. FOG is given special significance by the EPA and state environmental agencies due to its inability to mix with water, and its tendency to separate from liquid in the sewer system.
When FOG is released into the sewer lines in any amounts it can seriously degrade the collection system’s ability to remove waste from the city or community. FOG is deposited directly on pipe walls, thus decreasing pipe capacity and, therefore, requiring an increased frequency of cleaning, maintenance, and replacement.
FOG, and in particular, "grease" (grease is a fat that is solid and stable at room temperature) when dissolved in a warm and/or soapy liquid which may NOT appear to be harmful. However, when grease is released into the sewer system - it cools and then the grease solidifies when the grease and fats come out of the solution, which then adhere on the sewer pipe's surfaces.
Sewer lines meet at "lift stations" which are normally positioned in neighborhoods where small amounts of FOG collect and can become a problem. The FOG solidifies and creates huge grease "mats" on the surface of our sewer lift stations which interferes with the efficient functioning of removing sewage effluent from your home or business. These mats of FOG can actually shut the lift station down and if the problem is serious enough, the sanitary sewer lines can backup even to the point of threatening your home or business.

There may still be a solution which could include our Biogas Plant solution for your operation as well as several others in your area, whereby we collect and haul your FOG to our plant
How does our city or community solve FOG buildup problems?
Never pour grease down sink drains or into toilets!
Scrape all grease and food scraps from your plates, pots, pans, utensils, and grills and other cooking surfaces either into a coffee can or trash for pick-up.
Pour fats, oils and grease into a container such as an empty jar or coffee can.
put grease down your garbage disposal! Place a strainer in your sink's
drain to catch food scraps and other solids, and empty the drain
baskets/strainers into the trash for disposal.
What is Biomethane?
Biomethane is "renewable natural gas" made from organic sources - which starts out as "biogas" but then is cleaned up in a process called "Biogas to Biomethane" which removes the impurities in biogas such as carbon dioxide, siloxanes and hydrogen sulfides (H2S).
Biomethane is soon to be re-classified from the category of "Low Carbon Fuels" to "Super Low Carbon Fuel" due to it being the greenest of all biofuels!
and ready for use in an onsite cogeneration or
trigeneration power plant, the Biomethane could also be
sold to a pipeline company and completely replace the
"natural gas" that is typically transported to markets via the vast
underground pipeline system.
Biomethane will some day replace much of the "methane" or CH4 that is sold by natural gas utility companies.
Biomethane has an unlimited supply, whereas the methane sold by gas companies has a limited supply. Biomethane is renewable, whereas the methane sold by your gas utility company is not renewable. Biomethane recovery, use and production generates "Greentags" or a "Renewable Energy Credit" for the owners and is GOOD for our environment.
Biomethane is "naturally" produced from organic materials as they decay. Sources of Biomethane include; landfills, POTW's/Wastewaster Treatment Systems, and every tree or agricultural product that is no longer living. Biomethane is also generated from animal operations where manure can be collected and the Biomethane is generated from anaerobic digesters where the manure decomposes.
Biomethane, after installation of the Biomethane equipment is essentially free, as opposed to buying natural gas, presently costing around $10.00/mmbtu.
Methanogenesis is the production of CH4 and CO2 by biological processes that are carried out by methanogens.
Unlike the price of natural gas, which has been very unstable, and wildly fluctuating from $5.50 to as much as $17.00/mmbtu this past year, Biomethane prices will tend to be more stable over the years. As more and more Biomethane is produced, and produced in reliable and sustainable methods that can fuel our energy needs now and for.
It Comes to Energy Independence,
Biomethane, Not Coal, is America's "Ace in the Hole"
and One of the Greenest of All Biofuels

NOT Coal, is America's True "Ace in the Hole" when it comes to our
energy future, economics, the environment, sustainability and America's
“Energy Independence.” And biomethane is also receiving recognition as one
of the greenest of all biofuels.
years now, the coal industry has been touting "coal is America's 'Ace in
the Hole'" when they discuss the abundance of our coal reserves here in the
U.S. and the role they hope coal will play in America's energy future.
coal is far from being the “Ace in the Hole” the coal lobby would have
everyone believe. That’s due to
the proverbial “black eye” not to mention the “black lungs” and other
problems that are inherent with “dirty coal.”
there may be a place for coal in America's energy future, coal must become
"clean" for America to value it as a possible energy resource. Plans
or building 18 new Coal fired power plants were cancelled in Texas last year due
to the fact that coal isn't clean, and utilities aren't interested in investing
the extra costs for building power plants that use "Clean Coal
Technology" or "Integrated Gasification Combined Cycle" power
plants that also now need to include "Carbon Capture and
Sequestration" technologies to remove the carbon dioxide emissions from the
stacks. Plans for many other coal fired power plants are being cancelled. And
even now, owners of coal fired power plants (pulverized coal) are switching from
coal, to biomass, and biomass gasification technologies, as the writing is on
our society relishes the thoughts of moving back to the caves, and using
candles, and foregoing our modern-day comforts, we need to move forward with
renewable energy technologies such as biomethane, as the alternative is power
shortages and blackouts.
believe biomethane represents the best and greenest of all biofuels. There are
no supply problems with biomethane, and we have a virtually unlimited supply for
using biomethane wherever natural gas is presently used as a fuel.
should be pointed out that biomethane is chemically no different than natural
gas from the "fossil fuel" form of natural gas or CH4.
one important distinction between biomethane and the fossil-fuel variety of
natural gas, is that the production and use of biomethane is “carbon
neutral” in that the greenhouse gas emissions from biomethane use do not add
any new net greenhouse gas emissions.
starts out as “biogas” but must be cleaned and purified before it can be
used as a renewable fuel. The
process of cleaning and purifying the biogas is called “biogas to biomethane.”
The impurities that are found in biogas include hydrogen sulfides,
siloxanes, and carbon dioxide. When the impurities are removed from biogas, it
is then referred to as biomethane and available for use as a clean fuel, just as
the fossil-fuel form of natural gas is used.
Biomethane reserves and supplies, unlike fossil-fuel natural gas, are virtually unlimited. Biomethane is produced from many sources including anaerobic digesters, wastewater treatment systems, landfills and most agricultural and forestry operations. Last year, the first Biomethane NGV refueling station was opened in Eugendorf, Austria. Like a gas station provides gasoline for cars, the the NGV Biomethane station in Eugendorf provides biomethane for NGVs (Natural Gas Vehicles). Presently, the station provides a blend of biomethane and natural gas. Eventually, they hope to provide 100% biomethane for natural gas vehicles. Companies and researchers in Germany and Austria have determined that “Cellulosic Biomethane” is the greenest of all biofuels, and the least expensive biofuel to produce. Germany and Austria are now planting vast amounts of a form of Kentucky Bluegrass which will be harvested for use in producing “Cellulosic Biomethane,” through anaerobic digesters and fermentation.
from around the world, starting in Austria, are finding that grasses such as
Kentucky Bluegrass are easily converted into biomethane as well as organic
fertilizer. Cellulosic Biomethane production doesn’t require the fermentation
of sugars or starches - as the first generation of liquid biofuels – requiring
grains and oilseeds from food crops. As the Austrian Cellulosic Biomethane
project shows, biomethane can be produced from a cellulosic biomass feedstock
like grass. Yield estimates from the Austrian Cellulosic Biomethane research
indicate that one natural gas vehicle can travel 10,000 to 15,000 miles on just
one acre of Kentucky Bluegrass that was processed into biomethane.
a Jan. 8, 2009 public workshop held by the California Natural Gas Vehicle
Coalition, they documented the superior benefits and potential of biomethane as
a clean, renewable energy resource. The
California Natural Gas Vehicle Coalition stated that Biomethane should be
classified as a "Super Ultra Low Carbon fuel."
Super Ultra Low Carbon fuel is defined as providing at least an 82
percent reduction in greenhouse gas emissions - based on the California Air
Resource Board’s analysis of biomethane from landfill gas.

67.9 for natural gas
95.8 for diesel
96.7 for gasoline

diesel transportation fuel used - almost immediately.
to the California Energy Commission and the Biomass Collaborative, landfills,
wastewater treatment, and dairy waste sources - which are "developable
today" and can start producing Biomethane almost immediately, with low
investment/high returns, could yield 121 billion cubic feet of Biomethane. At
$8.00/mmbtu, that's a $1 billion market opportunity in California alone.
The 121 billion cubic feet of Biomethane equals about 860 million gallons
of petroleum diesel. California alone uses about 3 billion gallons of diesel
annually for transportation. Emerging biomass gasification and Biomethanation
technologies could more than double Biomethane supplies.
- like natural gas from "fossil fuels" - can be compressed or
liquefied. And using "Compressed Biomethane" is a significantly better
choice as a transportation fuel than traditional "natural gas."

and the economy than natural gas. Biomethane, when "vented" to the
environment, is 21 times more hazardous to the climate than carbon dioxide
emissions which are the only emissions (and water vaport) from compressed
natural gas vehicles' engines when used as a fuel.
we are reminded that Biomethane is the same chemical compound as natural gas:
CH4, and completely replaces and substitutes for natural gas. Engines, turbines,
boilers and every other natural gas appliance can use Biomethane without any
adjustments or modifications - just like natural gas.
supplies, as opposed to natural gas supplies from the fossil fuel industry, are
available in an unlimited supply.
forward with a “Biomethane Infrastructure” is the direction our country
needs to be moving as one of our fuel choices as we become energy-independent.
Every MCF of Biomethane that we use displaces about 8 gallons of gasoline
and creates jobs that will never be outsourced or downsized.

The Renewable Natural Gas & Greenest of all Renewable Fuels!
The Unlimited Potential for Biomethane and Renewable Natural Gas
Sweden is now leading Europe and the rest of the world in the pursuit of biomethane.
recent studies by researchers, professors and universities in Sweden, biomethane
is significantly more economic and less energy intensive to produce today than
any biofuel (i.e. E100
Ethanol and B100 Biodiesel, etc.).
If the U.S. were to similarly emphasize the production of biomethane as Sweden is now doing, the U.S. could significantly increase the supply of Biomethane - a renewable, clean fuel with an unlimited supply.
can be produced from landfill gas, sewage and animal and crop waste. Besides supplementing
our existing natural gas supplies, Biomethane
would provide huge greenhouse gas emissions reductions.
Based on an analysis conducted for the Department of Energy in the 1990's, it appears that at least 1¼ quadrillion BTUs of methane could reasonably be produced using exiting landfill gas to energy sites, wastewater treatment systems and animal waste sources - Concentrated Animal Feeding Operations alone.
If the Biomethane produces in the U.S. were used for natural gas vehicles, it would displace approximately 10 billion gallons of gasoline, per year! This is 10 times the amount (1 billion gallons of gasoline) per year projected for natural gas (the fossil fuel) in the Annual DOE outlook.
Regarding Greenhouse Gas Emissions and
Biomethane/Renewable Natural Gas vs. Gasoline
In the U.S., it is now feasible to capture and use about 1.25 quadrillion Btu's of Biomethane from landfills, animal waste and POTWs (wastewater treatment systems) alone. This is equivalent to about 6% of all of the natural gas presently used in the U.S.
Other Benefits and Incentives of Biomethane:

Equal to 2.0 cents per KWH (approximately $5.66 per MMBtu) for electricity produced on-site from

Biomethane technologies such as Anaerobic
Digesters and Biomass
Gasification development increases and becomes even more commonplace, one of
the fundamental questions is: what is the size of the potential biomass resource
supply in the U.S.?
In April 2005, the DOE and the U.S. Department of Agriculture (USDA) co-published a report assessing the potential of the land resources in the U.S. for producing sustainable biomass: Biomass as Feedstock for a Bioenergy and Bioproducts Industry: The Technical Feasibility of a Billion-Ton Annual Supply. Looking at forestland and agricultural land, the two largest potential biomass sources, this study estimates that the U.S. can sustainably produce up to 1.3 billion tons of biomass feedstock by mid-century. This would be enough feedstock to produce 60 billion gallons of B100 Biodiesel and E100 Ethanol with today's technologies.
This study doesn't address the opportunities for Biomethane production from biomass feedstock or Biomass Gasification technologies. Some recent estimates indicate that Biomethane could replace up to 50% of present natural gas consumption in the U.S. and in some countries, such as Iceland, Biomethane already provides 100% of the natural gas requirements.
are many assumptions in the Billion Ton Study report that impact these
estimates, but we believe the estimates reasonably reflect the potential
availability and impact of biomass resources.
Of the total estimated resource, the study suggests that forestlands in the contiguous United States can produce approximately 368 million dry tons annually. This projection includes 52 million dry tons of fuelwood harvested from forests and woodlands, 145 million dry tons of residues from wood processing mills and pulp and paper mills, 47 million dry tons of urban wood residues including construction and demolition debris, 64 million dry tons of residues from logging and site clearing operations, and 60 million dry tons of biomass from fuel treatment operations.
Biomass to Biofuels
By "converting" biomass wastes – such as municipal solid waste, sewage sludge, crop residues, energy crops, and manure – into biofuels, this will resolve the energy, environmental and political problems in an economical and environmentally sound manner - that will produce over one million new jobs.
to Jeff Seisler, Director of the European Natural Gas Vehicle Association,
an outstanding potential as a multifaceted solution to multifaceted social
problems: urban and agricultural waste management, water purification, and clean
air. Urban and agricultural waste can be processed into usable methane, as can
the sewage during the water purification process. Cleaning and compressing the
gas for use in vehicles then provides cleaner air than petroleum-consuming
Continuing, Mr. Seisler states about Biomethane; "this environmental 'closed loop waste-to-energy-to-fuel used in vehicles that again truck the next load of waste to the energy processing plants-substitutes fossil fuels with a renewable resource and reduces greenhouse gases 100% as compared to over gasoline vehicles (on a well-to-wheel basis).
to Peter Boisen Chairman, of ENGVA, "various well respected European
research institutes now estimate more than three times better fuel output per
hectare of land used than if going for ethanol or biodiesel. Sweden currently
has a 51% Biomethane
and Switzerland 37%. France, Norway, Germany and Austria use smaller amounts for
vehicles. Iceland, completely without natural gas, uses 100% biomethane in its
NGVs," Boisen says. Continuing, Boisen adds, "China, India,
Korea, the Ukraine, Spain and Italy are other examples of countries now starting
up projects where Biomethane
will be used as a vehicle fuel."
"With the energy efficiency of the gas production process at 50% to 70% it's hard to think of a more socially acceptable and economic energy value for the transportation sector," Boisen says.
"Governments need to get out of their liquid fuel paradigm to refocus and balance their policies and communications to support the development of a Biomethane infrastructure. In Europe Biomethane has the potential to replace 20% of the petroleum consumed in the transport sector by 2030."

Ends the worst economic depression of all time
“spending hundreds and hundreds and hundreds of billions of dollars every year for oil, much of it from the Middle East, is just about the single stupidest thing that modern society could possibly do. It’s very difficult to think of anything more idiotic than that.”
~ R. James Woolsey, Jr., former Director of the CIA
According to R. James Woolsey, for Director of the Central Intelligence Agency, “The basic insight is to realize that global warming, the geopolitics of oil, and warfare in the Persian Gulf are not separate problems — they are aspects of a single problem, the West’s dependence on oil.”
