“…Pig and dairy cattle slurries are an important source of NH 3 volatilization in agriculture as these animals represent the largest livestock production sectors in Europe (FAOSTAT, 2014;Philippe et al, 2011). Reducing such emissions is important, to minimize the highly negative effects on the environment and the health of animals (Wang et al, 2014;Bayo et al, 2012). Furthermore, reducing the N loss increases the fertilizer value of these slurries, leading to higher yields (Hoeve et al, 2016).…”

“…As these composting approaches could generate a significant volume of leachates (filtered liquid manure), the need for wastewater treatment remained. Natural treatment systems such as constructed wetlands (Bayo et al, 2012;Vázquez et al, 2013;Borin et al, 2013) have been suggested as being combined with liquid manure filtration through compost or vermicompost (Li et al, 2008) in order to reach the water quality to be recycled. Both composting and constructed wetland systems could offer an integral solution for the recovery of fertilizer elements contained in pig manure and diverse locally generated solid wastes.…”

“…But, the effluents from biogas plants with high nutrient contents are frequently discharged to the local environment owing to the shortage of arable land nearby, which, consequently, causes significant environmental burdens. The need for proper manure management of pig farms has been raised (Bayo et al, 2012; Nguyen et al, 2012).…”

Driven by the growing numbers of intensified pig farms around cities in China, there are problems of nutrient surplus and shortage of arable land for utilising the manure. Hence, sustainable livestock systems with effective manure management are needed. The objective of this study is to compare the existing manure treatment of a typical pig farm in Beijing area (separate collection of faeces; 'Gan qing fen' system) with an alternative system and to identify the nutrients flow of the whole farm in order to quantify environmental burdens and to estimate the arable land required for sustainable nutrients recycling. Life cycle assessment is used for this purpose. Acidification potential (AP), eutrophication potential (EP) and global warming potential (GWP) are analysed in detail; the functional unit is the annual production of the pig farm. The results show that the cropland area demand for sustainable land application of the effluent can be reduced from 238 to 139 ha with the alternative system. It is possible to transfer 29% of total nitrogen, 87% of phosphorus, 34% of potassium and 75% of magnesium to the compost, and to reduce the total AP, EP and GWP of manure management on the farm by 64.1%, 96.7% and 22%, respectively, compared with the current system. Besides an effective manure management system, a full inventory of the regional nutrients flow is needed for sustainable development of livestock systems around big cities in China.
