Anaerobic digester cost is expectantly high because this process is a proven and highly mature technology. The digester can produce natural gas or methane fuel using several organic waste materials, like manure and sludge. The technological capability is not questionable in the least. The economic benefit is also top class, hence the expected huge cost. However, you may not have to bear the cost except you need to go into mass production of methane fuel, which will enable you to recoup your expenses.
Even if you have to buy the digester, you should first consider the economic benefits regarding greenback, and also find out if buying it makes any economic sense before you ever buy. Find out about the system before placing your hard earned money on it. The anammox bacteria are the main organism used by the fuel system in digesting the various organic substances fed into it. Anammox is an acronym for Anaerobic Ammonium Oxidation, which represents the process the bacteria undergoes. The process is part of the very popular nitrogen cycle, which is one of the processes involved in the formation of fertilizer for agricultural processes. The bacteria were first identified far back in 1999, giving something unique for the scientific world to brood over.
There are certain scenarios that may prompt you to want to buy the digester. You need first to find out if the anaerobic digester cost will have a marginal benefit at such a time before placing your money on it. If the marginal benefit is nothing to write home about, then it will be unwise to invest in it. The methane produced by the digester is undoubtedly a source of energy. However, you need to find out if you would need the fuel generated at high quantity, which will determine if the setup will be financially beneficial or not. The digester may be useful in generating grid-ready electricity too, aside from being used in generating fuel for local uses.
One other factor that makes the anaerobic digester cost substantial is the fact that the process involved in fuel generation is entirely natural every step of the way. Aside from methane gas generation from organic waste, the digester can also generate carbon dioxide, which is also referred to as biogas. The anammox bacteria are group name for several bacteria. These bacteria are responsible for digesting the organic materials, and the digestion process takes place in step one after the other. The bacteria involved are anaerobic bacteria, which mean they can act even at low oxygen or where there is no oxygen at all. The first set of bacteria will prepare the way for the next one and so on until the process is completed.
The first set of bacteria is referred to as first-stage bacteria. Their function is to break down carbohydrate in a process called bacterial hydrolysis; this will lead to the production of various soluble materials, like amino acids and sugars. These sugars and amino acids are used by the next set of bacteria involved in the process. These new set of bacteria are responsible for consuming the biomass and converting it to other substances like ammonia, hydrogen, carbon dioxide and miscellaneous organic acids. The final product of the entire process is the production of methane gas. The mechanical aspect, rather than the processes involved, is responsible for the substantial anaerobic digester cost.
