“…Figures 3 and 4 present, respectively, the profile of methane and carbon dioxide concentrations, observed during the biodigester monitoring (12 samples along 80 days of biodigestion). The methanogenic phase, after the acid phase in the biodigestion process, is characterized by presenting methane concentration at a 50 to 60% level, with a decrease in the concentration of carboxylic acids and consequent increase in pH of the environment (Barlaz et al, 1989). Through Figures 3 and 4, it can be seen that, as the methanogenic phase advances, the methane concentration increases, while the carbon dioxide decreases, basically in the same proportion.…”

-This work focuses on monitoring the generation of biogas by biochemical methane potential (BMP) assays, commonly used to assess anaerobic biodegradability of solid and liquid wastes under controlled conditions. The experiment employed 5 g of substrate of both refuses (fresh and one-year-old wastes), digested with 250 mL of inoculum in 1 L flasks as bioreactors (all of them in triplicate, operating under batch conditions at ± 35 ºC). Despite the difference of age of both refuses evaluated, there was no significant differences in volume (near 1800 mL) and composition (55% methane) of biogas generated in 80 days of incubation under mesophilic conditions. The important parameters of both refuses (such as moisture content, volatile solids and chemical oxygen demand) also showed very similar initial values.

“…(a) Paper shows "a high level of biodegradability in a microbial dynamic condition" and huge decay can happen in a matter of weeks [1-3, 21 and 29]. The real constituents, cellulose and hemicellulose, are promptly separated when conditions are appropriate [1,32]. Disintegration is by and large slower in paper that is gotten from mechanical mash [20, 21 and 10], which contains a high extent of lignin -a "characteristic plastic" which is "gradually utilized by microorganisms in air" however is "organically dormant without sub-atomic oxygen" [28,32].…”

This study hired a spreadsheet model to simulate the greenhouse gas emissions (GGEs) from the newspaper production and intake system. The GGEs made by newspaper in Australia during 1994/95 were equal to about 13.5Mt of CO 2 , related to almost 2.5% of Australia's emission total. Over fifty percent of the amount contains CH 4 emissions from landfilled waste material paper. Misuse management options effective in minimizing GGE emissions from the newspaper life-cycle include incineration with energy restoration (most reliable), newspaper recycling, landfill gas restoration and composting. These studies can be expanded to other wood-based and organic and natural wastes.

“…Methane generation may be unpredictable and variable; production starts within a year of landfill filling and capping, and peaks 5-7 years after completion (Barlaz, Ham et al 1989). Methane production eventually slows to a fraction of the peak and is not longer usable for energy production.…”

“…Bioreactors use a design similar to sanitary landfills but enhance biodegradation by recycling leachate. Added water (gray water or sewage can be used) increases the rate of degradation by transferring nutrients and optimizing the growth conditions and therefore and metabolism of methane producing bacteria Barlaz, Ham et al 1989). Increased degradation rate produces more methane and increased degradation rate produces more settling.…”

Sustainable municipal solid waste management at military solutions necessitates a combined approach that includes waste reduction, alternative disposal techniques, and increased recycling. Military installations are unique because they often represent large employers in the region in which they are located, thereby making any practices they employ impact overall waste management strategies of the region. Solutions for waste sustainability will be dependent on operational directives and base location, availability of resources such as water and energy, and size of population. Presented in this paper are descriptions of available waste strategies that can be used to support sustainable waste management. Results presented indicate source reduction and recycling to be the most sustainable solutions. However, new waste-to-energy plants and composting have potential to improve on these well proven techniques and allow military installations to achieve sustainable waste management.
