“…As in the case of the N 2 O gas, the low solubility of CH 4 implies the necessity to operate the biofilters at high residence time values (2-30 minutes) [58]. For these reasons, nowadays, the interest has moved to remove the CH 4 directly from the liquid phase, before it is stripped to the atmosphere.…”

The operation of wastewater treatment plants results in direct emissions, from the biological processes, of greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as indirect emissions resulting from energy generation. In this study, three possible ways to reduce these emissions are discussed and analyzed:(1)minimization through the change of operational conditions,(2)treatment of the gaseous streams, and(3)prevention by applying new configurations and processes to remove both organic matter and pollutants. In current WWTPs, to modify the operational conditions of existing units reveals itself as possibly the most economical way to decrease N2O and CO2emissions without deterioration of effluent quality. Nowadays the treatment of the gaseous streams containing the GHG seems to be a not suitable option due to the high capital costs of systems involved to capture and clean them. The change of WWTP configuration by using microalgae or partial nitritation-Anammox processes to remove ammonia from wastewater, instead of conventional nitrification-denitrification processes, can significantly reduce the GHG emissions and the energy consumed. However, the area required in the case of microalgae systems and the current lack of information about stability of partial nitritation-Anammox processes operating in the main stream of the WWTP are factors to be considered.

“…Veillette et al (2012) for example describe how the system of biofiltration can substantially reduce emission of methane, but in Flanders and the Netherlands the economic viability of the system on a small scale, such as a farm, has been questioned (Van Dooren and Smits 2007).…”

Although several international carbon footprint (CF) calculation initiatives have been developed, studies that focus specifically on estimating the CF of pigmeat are rather limited. This paper describes the application of a CF methodology, based on lifecycle assessment of greenhouse gas (GHG) emissions, for Flemish pigmeat production using the Publicly Available Specification methodology (PAS2050, BSI 2011), which is at present the most developed method and relevant within the agricultural and horticultural sector. Both primary and secondary data have been used to model the meat system through a chain approach. The results are reported using the functional unit of 1kg of deboned pigmeat; and range from 4.8 to 6.4kg CO2 eq./kg of deboned pig meat. A sensitivity analysis has been executed on changes in herd and feed characteristics. The results have been compared with other studies on the CF of pigmeat in the European Union and with CF studies on milk and beef production in Flanders. Furthermore, two major hotspots in the CF have been defined: the composition and production of feed, and manure production and usage. It is important to mention that the CF is a good indicator for GHG emissions, but it is not an indicator for environmental impact in general. This paper helps to fill the void in the CF literature which existed around pigmeat products and to define a benchmark for CF of pigmeat

“…According to the literature related to biofiltration of exhaust air from animal houses, extremely large biofilter volumes would be required (Girard et al, 2011;Melse and Werf, 2005;Veillette et al, 2012). Melse and Werf (2005) state that this technology would not be a realistic option.…”

The performance of biofiltration to mitigate CH4 emissions from cow barns was investigated in the laboratory using two flow-through columns constructed with an acclimatized packed bed media composed of inexpensive materials and readily available in an agricultural context. The biofilters were fed with artificial exhaust gas at a constant rate of 0.036 m 3 h-1 and low inlet CH4 concentration (0.22 g m-3 = 300 ppm). The empty-bed residence time (EBRT) was equal to 0.21 h. Additionally, in order to simulate temperature changes under natural conditions and determine the influence of such cycles on CH4 removal efficiency, the upper part of the biofilters were submitted to temperature oscillations over time. The maximum oxidation rate (1.68 μg CH4 gdw-1 h-1) was obtained with the commercial compost mixed with straw. Accordingly, it was considered as packing bed media for the biofilters. The CH4 removal efficiency was affected by the temperature prevailing within the biofilters, by the way in which the cooling-warming cycles were applied and by the acclimatization process. The shorter the cooling-warming cycles, the more oxidation rates varied. With longer cycles, CH4 removal rates stabilized and CH4 removal efficiencies attained nearly 100% in both biofilters, and remained at this level for more than 100 days, irrespective of the temperature at the top of the biofilter, which was-at times-adverse for microbiological activity. The first order rate constant for CH4 oxidation kinetics of the entire system was estimated at 15 h-1. If such rate could be transposed to real field conditions in Canada, home to nearly 945,000 dairy cows, biofiltration may be applied to efficiently abate between 2 x 10 6 and 3 x 10 6 t yr-1 of CO2 equivalent (depending on how estimates are performed) from bovine enteric fermentation alone.
