“…This was in line with several other studies that reported short-term CH 4 emissions immediately after organic fertilizer application, due probably to volatilization of dissolved CH 4 from the applied substrate Chadwick et al, 2000;Wulf et al, 2002b;Jones et al, 2005;Amon et al, 2006). The longer lasting CH 4 emissions observed after the first application event at the slurry treatment of the C org -high site might result from the degradation of volatile fatty acids by methanogenic bacteria (Chadwick et al, 2000;Wulf et al, 2002b).…”

“…Significantly higher NH 3 losses from treatments fertilized with biogas digestate were observed compared to those fertilized with cattle slurry. This is in line with several other studies (Messner, 1988, Döhler and Haring, 1989(cited in Döhler and Horlacher, 2010; Amon et al, 2006;Möller and Stinner, 2009;Pacholski et al, 2010;Ni et al, 2011), whereas Pain et al (1990), Rubaek et al (1996), Wulf et al (2002a) and Clemens et al (2006) found no differences between anaerobic digested slurries and other animal slurries. However, it has to be taken into account that the present results are based only on measurements from a single application event.…”

“…Therefore, we must assume that we have missed most of the fertilizer-induced CH 4 emissions. However, all studies from literature confirm the minor importance of CH 4 emissions from applied organic fertilizers in the GHG balance of agricultural grasslands (Wulf et al, 2002b;Amon et al, 2006;Dietrich et al, 2012).…”

Abstract.A change in German energy policy has resulted in a strong increase in the number of biogas plants in Germany. As a consequence, huge amounts of nutrient-rich residues, the by-products of the fermentative process, are used as organic fertilizers. Drained peatlands are increasingly used to satisfy the huge demand for fermentative substrates (e.g., energy crops, grass silage) and the digestate is returned to the peatlands. However, drained organic soils are considered as hot spots for nitrous oxide (N 2 O) emissions and organic fertilization is additionally known to increase N 2 O emissions from managed grasslands. Our study addressed the questions (a) to what extent biogas digestate and cattle slurry application increase N 2 O and methane (CH 4 ) fluxes as well as the mineral nitrogen use efficiency (NUE min ) and grass yield, and (b) how different soil organic matter contents (SOMs) and nitrogen contents promote the production of N 2 O. In addition NH 3 volatilization was determined at one application event to obtain first clues with respect to the effects of soil and fertilizer types. The study was conducted at two sites within a grassland parcel, which differed in their soil organic carbon (SOC) and N contents. At each site (named C orgmedium and C org -high) three plots were established: one was fertilized five times with biogas digestate, one with cattle slurry, and the third served as control plot. On each plot, fluxes of N 2 O and CH 4 were measured on three replicates over 2 years using the closed chamber method. For NH 3 measurements we used the calibrated dynamic chamber method. On an annual basis, the application of biogas digestate significantly enhanced the N 2 O fluxes compared to the application of cattle slurry and additionally increased the plant N-uptake and NUE min . Furthermore, N 2 O fluxes from the C org -high treatments significantly exceeded N 2 O fluxes from the C org -medium treatments. Annual cumulative emissions ranged from 0.91 ± 0.49 to 3.14 ± 0.91 kg N ha −1 yr −1 . Significantly different CH 4 fluxes between the investigated treatments or the different soil types were not observed. Cumulative annual CH 4 exchange rates varied between −0.21±0.19 and −1.06 ± 0.46 kg C ha −1 yr −1 . Significantly higher NH 3 losses, NUE min and grass yields from treatments fertilized with biogas digestate compared to those fertilized with cattle slurry were observed. The total NH 3 losses following the splash plate application were 18.17 kg N ha −1 for the digestate treatments and 3.48 kg N ha −1 for the slurry treatments (36 and 15 % of applied NH

“…Furthermore, AD nowdays is very attractive in Europe and the number of plants is increasing [11][12][13]. Anerobic digestion has many benefits-it produces biogas rich in methane, which can be used to produce electricity and hot water [14][15][16], and emits lesser greenhouse gases (e.g., CH 4 , N 2 O) and NH 3 [17]. In addition, during AD, the waste is converted to a valuable effluent that can be used in agriculture, because of its high nutrient as well as organic matter contents [14,18].…”

“…Thus, the biogas production cycle generates intertwined agricultural and environmental benefits, like renewable energy production, cheap and environmentally healthy organic waste recycling, lower greenhouse gas emission (i.e. CH 4 , N 2 O and NH 3 ), pathogen reduction through sanitation, improved fertilisation efficiency (Holm-Nielsen et al, 1997;Amon et al, 2006;HolmNielsen et al, 2009;Comparetti et al, 2013a;Cucchiella et al, 2014;Eriksson et al, 2014), less nuisance from odours and flies (Birkmose, 2007), economic advantages for farmers. The digested biomass is transferred to storage tanks, which are usually covered with a gas proof membrane, in order to reclaim the remaining biogas (Holm-Nielsen et al, 2009).…”

In Italy, the Organic Fraction of Municipal Solid Waste (OFMSW) is nowadays landfilled or processed through aerobic composting. The Italian towns currently support a high cost for OFMSW disposal and cause a high environmental impact, because of long distances travelled from towns to a few available landfills and fewer treatment places, as well as the used waste management methods. An interesting option for OFMSW is Anaerobic Digestion (AD), producing biogas and "digestate". In this survey a theoretical biogas plant was placed near a town of Sicily Region (Italy), centralised with reference to the area considered for producing OFMSW. The distances travelled every year to transport OFMSW from the nine towns considered to the nearest composting plant and the biogas one were calculated using QGIS software. Therefore, the energy balance was computed for each of the four considered scenarios. Within the implementation of Integrated Solid Waste Management (ISWM) method, AD resulted in an energy balance much higher than that of aerobic composting. In fact, differently from composting, AD can significantly contribute to energy recovery, while retaining the nutrients in the digestate produced and reducing Greenhouse Gas (GHG) emissions. The use of a rational network of towns for OFMSW collection and transportation results relevant, in terms of increased energy balance, only in the case of composting. Therefore, if AD would be implemented as OFMSW management method, by means of biogas plants, each of them placed in an area including some towns, e.g. that considered in this survey, it could highly reduce the cost and the environmental impact of waste disposal.
