What is BioMethane, BioMethanation and
generated from organic materials as they decay. Sources of
BioMethane include; landfills, POTW's/Wastewaster Treatment Systems, and
from animal operations where manure can be collected and the BioMethane is
generated from anaerobic digesters where the manure decomposes.
after installation of the requisite equipment, is essentially free,
as opposed to buying natural gas, presently costing around $6.00/mmbtu.

Gasification and BioMethanation Technology
process of Biomass Gasification produces BioMethane. BioMethane is also
produced in anaerobic digesters, in the process called anaerobic
digestion. BioMethane is a renewable energy resource, as opposed to
natural gas (methane), which is a non-renewable energy resource.
BioMethane has similar qualities of methane and both are used in
interchangeably, and each may be a substitute for the other.
The production and disposal of large quantities of organic and biodegradable waste without adequate
or proper treatment results in widespread environmental pollution. Some waste streams can be treated by conventional methods like aeration. Compared to the aerobic method,
the use of anaerobic digesters in processing these waste streams provides
greater economic and environmental benefits and advantages.
As previously stated,
Biomethanation is the process of conversion of organic matter in the waste (liquid or solid) to
BioMethane (sometimes referred to as "BioGas) and manure by microbial action in the absence of
air, known as "anaerobic digestion."
Conventional digesters such as sludge digesters and anaerobic CSTR (Continuous Stirred Tank
Reactors) have been used for many decades in sewage treatment plants for stabilizing the activated sludge and sewage solids.
Interest in BioMethanation as an
economic, environmental and energy-saving waste treatment continues to gain
greater interest world-wide and has led to the development of a range of anaerobic reactor designs. These high-rate,
high-efficiency anaerobic digesters are also referred to as "retained biomass reactors" since they are based on the concept of retaining viable biomass by sludge immobilization.
Biomass Gasification and the Production of BioMethane
Biomass is a renewable energy resource which includes a wide variety if organic resources. A few of these include wood, agricultural residue/waste, and animal manure.
Biomass Gasification is the process in which BioMethane is produced in the BioMass Gasification process. The BioMethane is then used like any other fuel, such as natural gas, which is not a
Historically, biomass use has been characterized by low btu and low efficiencies. However, today biomass gasification is gaining world-wide recognition and favor due to the economic and environmental benefits. In terms of economic benefits, the cost of the
BioMethane is essentially free, after the cost of the equipment is installed.
BioMethane, probably the most important and efficient energy-conversion technology for a wide variety of biomass fuels.
The large-scale deployment of efficient technology along with interventions to enhance the sustainable supply of biomass fuels can transform the energy supply situation in rural areas.
It has the potential to become the growth engine for rural development in the country.
Principles of Biomass Gasification
Biomass fuels such as firewood and agriculture-generated residues and wastes
are generally organic. They contain carbon, hydrogen, and oxygen along with some moisture. Under controlled conditions, characterized by low oxygen supply and high temperatures, most biomass materials can be converted into a gaseous fuel known as producer gas, which consists of carbon monoxide, hydrogen,
carbon dioxide, methane and nitrogen. This thermo-chemical conversion of solid biomass into gaseous fuel is called biomass gasification. The producer gas so produced has low a calorific
value (1000-1200 Kcal/Nm3), but can be burnt with a high efficiency and a good degree of control without emitting smoke. Each kilogram of air-dry biomass (10% moisture content) yields
about 2.5 Nm3 of producer gas. In energy terms, the conversion efficiency of the gasification process is in the range of 60%-70%.
Multiple Advantages of Biomass Gasification in Methane Production
Conversion of solid biomass into combustible gas has all the advantages associated with using gaseous and liquid fuels such as clean combustion, compact burning equipment,
high thermal efficiency and a good degree of control. In locations, where biomass is already available at reasonable low prices (e.g. rice mills) or in industries using fuel wood,
gasifier systems offer definite economic advantages. Biomass gasification technology is also environment-friendly, because of the firewood savings and reduction in CO2 emissions.
Biomass gasification technology has the potential to replace diesel and other petroleum products in several applications, foreign exchange.
Applications for Biomass Gasification
Thermal applications: cooking, water boiling, steam generation, drying etc.
Motive power applications: Using producer gas as a fuel in IC engines for applications such as water pumping
Electricity generation: Using producer gas in dual-fuel mode in diesel engines/as the only fuel in spark ignition engines/in gas turbines.
Publicly Owned Treatment Works ("POTW's")
or Wastewater Treatment Systems
More and more,
cities, counties and
municipalities are faced with greater environmental compliance issues relating
to their municipally-owned landfills, Publicly Owned Treatment Works ("POTW's")
or Wastewater Treatment Systems.
A city's landfill and/or POTW provides an excellent
opportunity for cities to reduce their emissions as well as provide an
additional revenue stream. These facilities may have valuable gases
that our company recovers and pipes to one of our clean,
environmentally-friendly cogeneration or trigeneration energy
company provides economic and ecological
solutions for cities and municipalities
with environmental liabilities (air emissions) associated with POTW operation
and provide a new cash flow simultaneously. We offer turn-key
solutions for cities that includes the preliminary feasibility analysis,
engineering and design, project management, permitting and
commissioning. We provide very attractive financing packages for
cities that does not add to a city's liability, yet provides a valuable
new revenue stream. And, we are also able to offer a turn-key
solution for qualified municipalities that includes our company owning,
operating and maintaining the onsite power and energy plant.
At the heart of
the system is a (Bio) Methane Gas Recovery system similar those used in Flare Gas Recovery or Vapor Recovery
Units. Methane Gas Recovery, Flare Gas Recovery,
Vapor Recovery, Waste to Energy and Vapor Recovery Units all recover valuable
"waste" or vented fuels that can be used to provide fuel for an
onsite power generation plant. Our waste-to-energy and waste to fuel
systems significantly or entirely, reduces your facility's emissions (such
SOx, H2S, CO
, CO2 and other Hazardous Air Pollutants/Greenhouse Gases) and convert
these valuable emissions from an environmental problem into a new cash
revenue stream and profit center.
and vapor recovery units can be located in hundreds of applications and
locations. At a landfill, Wastewaster Treatment System (or Publicly Owned
Treatment Works - "POTW") gases from the facility can be
captured from the anaerobic digesters, and manifolded/piped to one of our
onsite power generation plants, and make, essentially, "free"
electricity for your facility's use. These
that are generated from municipally owned landfills or wastewater
treatment plants have low btu content or heating values, ranging around
550-650 btu's. This makes them
unsuitable for use in natural gas applications. When burned as fuel to
generate electricity, however, these gases become a valuable source of
"renewable" power and energy for the facility's use or resale to
the electric grid.

cogeneration or trigeneration system into the project and provide some, or
all, of your hot water/steam requirements. Similarly, at crude oil
refineries, gas processing plants, exploration and production sites, and
gasoline storage/tank farm site, we convert your facility's "waste
fuel" and environmental liabilities into profitable,
