“…As seen in Table 1, the CV of the dry GM was only about 13 MJ/kg on a dry basis, which was relatively lower than the data (i.e., 15-20 MJ kg −1 ) on biomass residues and cattle manures [18,20]. According to the study by Jenkins et al [19], each 1% increase in ash translates roughly into a decrease of 0.2 MJ/kg of CV.…”

“…Renewed interest on using animal manure for fuel is due in part to the necessity of disposing large amounts of manure [103,104,105,106]. Studies on using dairy manure for heat production, as an alternative to AD or composting, have been reported in several publications [103,104,105,106,107,108,109,110,111,112,113,114,115,116,117].…”

One of the consequences of the increase of large dairy concentrated feeding operations (CAFOs) is the abundance of dairy manure that needs to be disposed of or used in some way. CAFOs can become bio-refineries, harnessing the manure for heat, power, fuel, chemicals, fertilizers, fiber, wood composites, and biochar for production of multiple value-added co-products. The objective of this paper is to review options for using dairy manure fiber and its corresponding anaerobically digested (AD) fiber. Bedding for cows remains a common choice for employing the separated AD fiber. However, research has shown that AD fiber has potential for using it as a component of growth substrates used in container plant production systems, for producing composite materials, or as a feedstock for both chemical and thermochemical operations. Potential uses of AD fiber such as composite materials and liquid fuels are proposed based on experiences employing the manure and its fiber (both without a previous AD step and after AD). Thermochemical processing (e.g., liquefaction and pyrolysis) of AD fiber for fuels and chemicals has been conducted at laboratory level and still needs further study at larger scale. Gasification of AD fiber is a promising option since there is potential for integration of current methane production with methane produced from thermal gasification.

“…They include on-site gasification, fluidized beds, 5 and circulating fluidized beds. 4 A few of the technologies met with success, but the projects were complicated by the highly variable properties of manure. Anaerobic digestion is a slow process, resulting in emissions over a longer period of time; it requires liquefaction and the use of precious water, and does not result in complete conversion of the solids into gas.…”

Powerplants spend nearly 50 billion dollars a year on fuel cost, and coal accounts for over 55% of the fuel used in the utility industries. The fuel cost could be reduced by supplementing coal fuels with alternative renewable fuels such as the byproducts of industries located in the vicinity of the powerplants. One of the byproducts of feedlots is manure, a biosolid fuel that is cheaper than coal, on a tonnage and heat-value basis. Coal-manure blend or, more simply, "blend" technology is proposed as a beneficial use of manure for powerplants located near feedlots. Experiments were performed in a small-scale boiler burner facility with coal only, and then for 80:20 blends on a wet-weight (as-received basis). Data were taken during the warm up, gasification, and combustion. Three types of feedlot manure were examined for blending: raw feedlot, partially composted feedlot, and finished composted feedlot. A summary of the findings is as follows: 1) Manure contained up to 80% volatile matter (VM) on a dry ash-free basis, which was twice the VM of conventional coal. 2) Combustion efficiency was slightly higher with the coal-manure blend than with coal. 3) NO A emission increased from 420 ppm at 80% burned fraction (BF) to 550 ppm at 95% BF for coal, whereas corresponding numbers for the blend were 620-550 ppm. 4) SO* increased from 30 to 180 ppm for coal, whereas for the blend it was nearly 0 ppm up to 90 % BF, but increased to 10 ppm at 95% BF.
