Research by David House says that 1000lbs of human waste can produce 0.6 cubic meters of biogas. The most common types of biogas digesters are wet biodigesters. For a wastewater with a temperature of 20 o C and a COD of 20 g/l, the production of biogas yields around the same amount of energy required to raise the temperature of the liquid to 35 o C. Thus, for low and medium strength wastewaters, treatment only at ambient temperatures is practical. Biogas has a high energy content which is not less than the energy content of the fuel fossil [6]. In addition, there are almost 12,000 minor facilities (less than 1 MGD in size), and only a small number of these operate anaerobic digesters. However, not all waste is created equalsome materials are naturally more adept than others at generating biogas. Biogas fuel is a flammable substance that burns in a similar fashion to liquefied petroleum gas (LPG), and as such, biogas energy can be utilized as an alternative to fossil fuels.Biogas production is often achieved using a biogas plant, which is a system that "digests" organic matter to produce gas. The U.S. Energy Information Administration (EIA) estimates that in 2020 about 256 billion cubic feet (Bcf) of landfill gas was collected at 327 U.S. landfills and burned to generate about 10 billion kilowatthours (kWh) of electricity, or about 0.3% of total U.S. utility-scale electricity generation in 2020. It is a renewable gas which gives a lot of flexibility for utilisation. . But, only 45.2% of this energy went towards cooking and heating. . And the residue, dried and charred, could produce 2 million tonnes of charcoal-equivalent fuel, curbing the . Biogasabout 60 percent methanecan be produced by having bacteria break down human feces. The calorific value of biogas is variable (depending on methane content) at 20-26 MJ/m3 (5.6-7.2 kWh/m3) [22]. The World Bank and the United Nations actively encourage its use as a cheap, clean energy source. Biogas from cow manure with 1 kg produced as much as 40 liters of biogas,while chicken dung with the same amount produced 70 liters. Biofertilizer can be sold to farmers and gardens or used on-site for gardens and landscaping. Answer: Well it does vary according to the type of crop and moisture content, type of pre-treatment used and total carbohydrate, Lignin, etc in the raw material. Compared to controls that contained no powdered chicken feathers, the biogas produced when the feathers were co-digested with the human waste contained, at minimum, 68% less nitrogen and 73% more methane. Nearly two-thirds of the 3,200 major WWTPs in the U. S. (those greater than 1 MGD) do not send solids to anaerobic digestion and produce biogas.
