Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Comprised primarily of methane and carbon dioxide, biogas originates from biogenic material and is a type of biofuel. It’s a product of the anaerobic digestion or fermentation of biodegradable materials such as manure or sewage, and can be used in CHP plants

Biogas is created in landfills. When organic matter such as compost or natural waste is buried without oxygen, it starts to create a gas. This is biogas and it can be contained and used to produce energy. A landfill that is properly designed will produce biogas for several years. This gas is released into the earth’s atmosphere, so it just makes sense that harnessing it and making use of it would be a better solution. As far as natural resources go, this might be one of the best.

For the most part biogas is made up of carbon dioxide and methane. However, quite often there are also varying quantities of hydrogen, oxygen, nitrogen and various other natural gases. Special wells have to be drilled in order to properly get biogas out of a landfill. It is a much more efficient way of capturing all of the gas. At this time there is a train in Sweden that is currently powered by biogas. The use of sewage and cow waste is the primary fuel source for that train. It has been determined that biogas has virtually no trace of toxic emissions in comparison with fossil fuels.

There are several great benefits to using biogas as fuel. Not only does it produce much needed energy but it also eliminates all of the organic waste in landfills by giving it a purpose. This in turn also improves conditions in landfills regarding insects and the reduction of pathogens. Reducing the amount of methane in the earth’s atmosphere is also a good idea which biogas helps with as well. Those that are interested in the benefits of biogas should do the necessary research in order to understand it better. As consumers and members of this earth, we all must do our part to make an educated choice.

There are a handful of disadvantages associated with biogas as well. The actual product value of biogas is incredibly low, which does not necessarily make it economically feasible. The process that is required to obtain biogas can also be quite expensive since special wells must be drilled. There is also reason to believe that some of the gases in biogas are corrosive to metal. This can be a problem because metal is a major component of automobile engines. Weighing the benefits and disadvantages is necessary in order to conclude if biogas will work for you.

Biogas is a mixture of about 60-70% methane (natural gas), 30-40% carbon dioxide and other trace gases, such as hydrogen sulfide. The heat content of this gas is based on the amount of methane it contains and is about 600 BTUs per cubic foot.

Anaerobic digesters produce biomethane along with electricity generation and saleable end product biosolids which allows animal production enterprises to become neighborhood and environment friendly, as well as producing another revenue flow for themselves.

Running a biogas plant on a dairy farm works best for farms which hold at least 800 cows. Economically viable ystems for dairies under 800 cow level are possible, but need evaluation on a farm by farm basis to decide whther there will be adequate cost effectiveness. No farm or combinations of farms is ever likely to be too large for such a system.

Whether a particular farm, your farm perhaps, would be suitable for a biogas plant depends on assessing the budget costs of the investment, against the potential earnings from generated electricity sales and from end product bio-solid sales. The economic return period for any farm can be estimated this way. If the return period is short enough and an investor can be found there is a lot to be said for going ahead.

Many people will ask you to demonstrate that the new plant does not have a negative impact on the surrounding environment. Let us assure you that a well designed and run biogas plant improves the environment significantly and is neither odorous nor dangerous. Such plants can be placed near production facilities which will often be the best customers for the power and heat produced.

Equipment is fitted to the digester plants to suit climate conditions. The bioreactors have thermal insulation and are heated by heating and also have a cooling system for summer use. In cold winters a biogas plant can consume up to 50% of its produced heat power.

The liquid that results from the anaerobic digestion process has solids which are separated out, composted, and sold to local gardeners, landscapers and farmers. Some farmers use the solids as bedding for their cows and sell it as bedding to neighbors. The liquids are returned to the farmer as nutrient rich natural fertilizer, which replaces imported nutrients and thereby cuts costs.

There is an issue, and it is a fallacy, going around that Anaerobic Diesters always smell. We would contest this. Anaerobic digesters actually tend to alleviate odor problems when on a well run, especially as suburban growth surrounds farms and introduces neighbors who complain about manure smells most often due to nearby farming activities and not the AD plant at all.

By installing an anaerobic digester, the conscientious farmer can actually solve odor issues to everyone’s satisfaction. Since the digesters are airtight, the smell stays within, and the liquids and solids coming out of the digester have only a very slight odor compared to the raw slurry.

Biogas is created during the breaking down of organic waste inside a landfill. It is called anaerobic digestion. Organic matter such as plant life releases the gas after it has been buried without any oxygen for awhile. A landfill will actually generate biogas for many years after the organic waste has been buried. This gas has been proven to be effective in producing energy that can be used to power cars. There are now landfills designed just for the purpose of creating biogas.

Biogas is actually made up of several different types of gases. The two primary gases found in biogas are carbon dioxide and methane. Along with that can be various traces of oxygen, hydrogen and nitrogen. The biogas does have to be put through a cleaning process before it can be used. Once it is ready though it could possibly power everything from cars to businesses. It can even be used for cooking.

Collecting biogas from the landfill is a pretty large task. It involves the use of gas wells which have to be drilled to properly obtain the biogas. The cost involved in this can be quite substantial which may be one of the downfalls to the use of this fuel source. Sweden is currently running a train solely on biogas between the cities Linkoeping and Vaestervik. The biogas used in the train is derived primarily from the waste of cattle and sewage. It certainly is interesting to see how waste can be made into something viable and useful.

Biogas certainly has other great attributes. It has far less carbon dioxide than diesel and gasoline. The emissions do not contain any of the same toxins and fossil fuels. If it could be obtained easier then perhaps it would be useful to the general public. However, even the best resources will have disadvantages. There are many pollutants that can be found in the burning of biogas which makes it an environmental risk. There is also a really high risk of bacteria because the management of it can be very sensitive. Production of biogas is not a simple process at all. The hard work involved does make biogas rather difficult to obtain.

Biogas simply is not common enough for public consumption at this point. Perhaps with more time and work it could become something that would be a great option that would also help the earth. Biogas remains a fantastic option that is still better than fossil fuels.
