Anaerobic digestion has thus emerged as an alternative waste treatment method to the aerobic digestion processes, mainly due to its higher organic matter degradation rate, with little sludge formed, and the production of energy through the synthesis of biogas, in addition to producing biofertilizers as an ending product (Mohama et al., ). Methods for stabilizing livestock wastes include composting, aerobic digestion, anaerobic digestion, lime stabilization, and heat drying. The stabilization process reduces the organic matter and water contents, unpleasant odors, concentrations of pathogenic microorganisms, and weed seeds. -Anaerobic Digestion of Organic Wastes - 5 1 Introduction to anaerobic digestion History of anaerobic digestion Historical evidence indicates that the anaerobic digestion (AD) process is one of the oldest technologies. However, the industrialization of AD began in with the first digestion plant in Size: KB. Anaerobic Digestion Wastes Characteristics. Anaerobic digestion feedstocks can vary widely based on their organic fraction, water content and biodegradability. Usually, it is expected that organic content of the feedstocks should be in the range of 70% - 95% of the dry matter content.
This laboratory study was initiated with the purpose of determining the aerobic and anaerobic digestion characteristics of livestock wastes. Hog, cow, and sheep manure were digested anaerobically in bench-scale digesters. First stage BOD and oxidation rate constants were measured for these same : Edgar A.

EC and by the University of Illinois under solid waste research grant no. EC was written by D. D. JONES, D. L. DAY, and A. C. DALE and has been reproduced as published by the University of Illinois. Anaerobic Digestion (AD), which is the most prominent bioenergy technology worldwide, is a profitable alternative that provides a sustainable solution to treat organic wastes and reduce greenhouse.

Anaerobic Digestion of Municipal Solid Waste is carried-out in so-called “MBT” plants on the organic fraction of the residual waste (i.e.”black bags”) collected from households, and businesses on behalf of Municipal Solid Waste Management bodies (I.e. local authorities and businesses). In the developed nations a significant amount of food waste is present. A major limitation of anaerobic digestion of FVW is a rapid acidification of these wastes decreasing the pH in the reactor, and a larger volatile fatty acids production (VFA), which stress and. ] AEROBIC TREATMENT OF LIVESTOCK WASTES 19 The sludge does not decompose well, however, because of the high degree of mineralization, as witnessed by the fact that only about half as much gas is produced in the digestion of the sludge as compared with sludge from a conventional activated sludge plant. Anaerobic digestion is an alternative solution to livestock waste management that offers economic and environmental benefits. This publication provides an introduction to the technology of bio-gas, digester design considerations, and system costs with discussion of the .
