One of the most effective solutions is to implement the uses of renewable energy sources. In particular, biomass, which can be further converted into biofuel, is normally derived from plants.
However, it brings several drawbacks which may directly threaten the sensitive species. To alleviate these, biogas production from poultry manure wastewater was explored in the current work. Its usage to produce biogas was considered as a triumph to the concept of waste-to-wealth. The main objective of this research study was the optimization of biogas production from poultry manure wastewater by soil mixed culture. The poultry manure collected was gone through characterization and pre-treatment processes to remove excessive ammonia-N which cause inhibition to the biogas production.
The optimization was analyzed by central composite design CCD. Previous studies have screened out five processing parameters, which were agitation speed, reaction time, substrate to inoculum ratio, process system and type of substrate. Significantly, it had been identified that agitation speed and reaction time were the most crucial parameters. The best screening condition obtained from previous studies was rpm agitation speed and 3 days of reaction time.
Consequently, there were two factors involved in current research study, which are agitation speeds ranged from rpm to rpm; and reaction time ranged from 2 days to 5 days. The biogas production was collected by water displacement experimental set up.
Lastly, the experiment was designed and analyzed by Design Expert V7. The biogas production performance was evaluated on the basis of biogas yield from initial COD and was found ranging from 0.
Estimates used currently suggest that cows are currently about 16 times more efficient than the best modern biogas plants! So, the biogas production industry has some way to go yet! Because biogas can make a positive contribution to multiple goals in government programmes, it has the potential to increasingly become one of the most efficient and economical sources of renewable fuel with anaerobic digestion an economically viable technology for both small-scale rural applications in developing countries and for a range of scales in the developed world IEA Bioenergy, Task 37, Despite this some experts believe biogas will have limited use worldwide, with more potential in hydrogen fuel cells or electric motors.
These experts seem to miss the point in this regard as hydrogen fuel cells always need recharging and that energy can readily come from biogas.
In Europe and worldwide, production and use of biogas has increased considerably as a result of increasing demand for renewable energy as a substitute for fossil energy. And, also in order that nations can comply with their commitments to reduce carbon emissions in-line with the Paris Accord of In Germany, a new market study by Ecoprog concluded that 2, MW of new biogas will be constructed by , and that Europe will remain the most important market for new biogas plants.
This will to enable them to draw up robust business plans and strategies for investment in biogas facilities. So, that in the future a very large volume of biogas output, will be integrated into the European farming systems. We have run out of space now, without even mentioning the many advantages of biogas to communities, and the waste disposal merits for farming and how the process can provide great respiratory health benefits by avoiding the need for open fires in the homes of those in the developing nations.
Nor have we discussed how home AD plants can release women in developing nations from spending many hours daily collecting firewood. Those, and yet more benefits, are covered in our other pdf formulated eBooks, and in our website articles.
Biogas can be produced on a large scale commercially, and at all scales down to the very small scale for household use, mainly for cooking, lighting, and water heating. Rapid development has taken place in the development of biogas technology to optimize the efficiency of biogas processes. This work only started in earnest in the mid s and yet already promises big advances in the total yield, and rate of yield of the methane gas, while also maintaining and improving process stability and up-time for AD plants.
On the large scale, new methods in development which are using pre-treatment for more rapid hydrolysis and the introduction of the large scale use of enzymes, and even industrial style microwaving of feedstocks, are showing great promise. These efficiency gains in conjunction with the effect they are having in releasing far more organic waste previously thought of intransigent as a biogas fuel, as material for bio-digestion such as chicken litter.
On the small scale, the idea of home biogas plants which for so long has been only possible in hot developing nations, seems to be opening up for the wealthy countries too. Looking into the future, it looks increasingly unlikely that water resources can forever continue to be found for wet-flushing toilets in western nations, but guess what?
To couple that with a home biogas plant could provide energy to self-power the toilet wipe clean mechanism and operate the biogas plant itself with energy to spare for use in the the home. We hope you have found this biogas pdf useful, and that you will go away as convinced as we are, that the future of this technology has only just begun!

Advanced Technology for the Conversion of Waste into Fuels and Chemicals: Volume 1: Biological Processes presents advanced and combined techniques that can be used to convert waste to energy, including combustion, gasification, paralysis, anaerobic digestion and fermentation.
The book focuses on solid waste conversion to fuel and energy and presents. DBA Journal eBook We are incredibly satisfied…. Apart from being very informative about the topic with a very deep coverage, it is very easy to understand and easy to find what you are looking for. I also very much like your distance from the whole topic without losing depth.
It is very funny to read and easy to understand. Hopefully we can contribute to forthcoming editions of this bible of biogas. A business development expert creating alternative energy projects and biogas plants worldwide.
Almost 30 substrates— digestible plant wastes, manure and so on— are discussed and known research about them is presented in considerable detail:. Taking the lower figure, a ton of cornstalks would furnish gas for people for one day, allowing 25 cubic feet per capita per day. From the data given by Weber for yields from regions where 30 percent of the land is planted to corn, an area with an 8-mile radius will produce enough cornstalks to supply a city of 80, inhabitants continuously.
In other words, the cornstalks from one acre will produce the gas for one person for a year. Biogas research has occurred using pig manure as a substrate because of the economic importance and the large population of pigs. Therefore, information specifically about pig manure is available whereas information about llamas , peacocks, gerbils, elephants , gnus, large herds of wild voles and the like is totally absent.
Chapter Manure Substrates , pg. This book offers extensive information about all aspects of biogas production, and details some small-scale designs. For example, the design for a simple, low-cost test generator is provided, and other novel design ideas based in solid research are offered:. If you achieve this kind of production from the two-barrel methane module of the proposed hybrid generator, it would produce about 3, liters of biogas per day, or nearly 2, liters of methane per day respectively, and 95 cubic feet.
In terms of the energy in that much methane, 2.
