The negative environmental impacts of agricultural waste typically draw attention. However, agricultural waste has beneficial uses as an energy source, chemical recycling agent, and chemical adsorbent. This review examines the characterization, reuse, treatment, and management (minimization) of agricultural waste. Agricultural Water Pollution. Pierantozzi et al. (2012) examined physicochemical, toxicological, and genotoxicological properties of olive mill wastewater, olive wet husk, and olive brine. The results showed that olive wastes' inhibitory effects on seed germination and seedling growth, and the direct use of olive wastes for other agricultural processes should be limited because of their possible chemotoxic, phytotoxic, and antimicrobial effects.

“…Therefore, the methane production shown from Day 107 to Day 260 was caused by the decrease of the activity of methanogens due to temperature. Yuan et al (2012) evaluated the methane production characteristics of cattle carcasses through anaerobic digestion [9]. According to the results, the methane production of a reactor with the addition of anaerobic sludge increased 1.8 times more than that of the control.…”

“…Livestock carcasses are biodegraded under anaerobic conditions. The leachate produced from the burial sites contains relatively high concentrations of contaminants compared to groundwater and has been reported to be a potential cause of contamination of soil and groundwater [6][7][8][9]. The gas generated from burial sites consists of mainly of methane and carbon dioxide, and its contents are affected by seed microorganisms [10].…”

Characteristics of Pollutants and Microbial Communities Obtained in Simulated Lysimeters of Swine Carcasses

Abstract:This study was performed to investigate the characteristics of pollutants and microbial communities obtained in simulated lysimeters and to evaluate the effects of anaerobic sludge and water on the biodegradation of swine carcasses. The leachate production rates of Lysimeters 2 and 3 with the addition of anaerobic sludge were higher than that of Lysimeter 1 (control). The methane production rate of Lysimeter 3 with anaerobic sludge addition and increased water content was higher than those of other lysimeters. The result of microbial community analysis revealed that the relative abundances of Proteobacteria including pathogens in Lysimeter 3 were lower than those in other lysimeters. Overall, this study demonstrated that the proper operating conditions of lysimeters accelerated the stabilization of swine carcasses and could contribute to sustainable land use.

“…Some studies on GHG emissions of other animals' carcasses have been reviewed. For example, a recent experimental study on cattle carcass management methods in the US (Yuan, Saunders and Bartelt-Hunt 2012) estimated that a single cattle carcass of average weight (500 kg) released 50 m 3 (36 kg) of methane and 14 m 3 (25 kg) of carbon dioxide at a standard temperature and pressure, which corresponded to approximately 720 kg CO 2 equivalent. Other researchers have focused on co-composting of animal carcasses with their manures under a controlled environment such as a landfill or a composting system (e.g.…”

Camel culling and carbon emissions in rangelands in central Australia

Culling feral camels will impact on the carbon emissions from them. Culling of feral camels stops their long-term continuous methane emission, but emits carbon from their carcasses in the short term. Through on-site monitoring of the decomposition process of camels that have been shot dead, this paper models the pattern of carbon emissions during the decomposition of these camels in Central Australia, and analyses the contribution of the camel culling programme to carbon emission mitigation on the rangelands. A 'carbon royalty' payment mechanism is also suggested to encourage local participation in carbon markets through an involvement in natural resource management.
