“…Compared to the management system without the treatment plant, the system with treatment reduced GWP by 70% and AP by almost 50%. These results are in line with [8,62]. The GWP reduction obtained with the treatment system was greatly influenced by the renewable energy production achieved by AD (−35%), by the low CH 4 emissions (6% from the treatment plant and 34% from farm storage), by the low N content of treated effluent in the final storage, and by the land application of treated AD digestate.…”

“…The treatment plant was monitored following the common evaluation and monitoring protocol developed in the European Union-sponsored LIFE +MANEV project (LIFE09 ENV/ES/000453) [8]. Monitoring covered 5 years of steady operation of the treatment plant (January 2011-December 2015).…”

“…Most of them treat swine slurry achieving higher performances in the reduction of TKN and TP than digestate, probably because swine slurry has a lower TS content and a higher TAN /TKN ratio that make them easier to treat. For example, [8] studied various full-scale integrated treatment plants consisting of solid-liquid separation, coagulation-flotation, and NDN, and reported 91% TKN removal and 89% TP removal. The researchers reported similar performance (85% TKN removal; 86% TP removal) for a Sharon-SBR biological treatment process that was preceded by AD and solid-liquid separation.…”

The aim of this 5-year study was to evaluate the technical, economic, and environmental performances of a collective-based integrated treatment system for bioenergy production and nutrients removal to improve the utilization efficiency and reduce the environmental impact of land applied livestock manure. The study involved 12 livestock production units located in an intensive livestock area designated as nitrate vulnerable zone with large N surplus. The treatment system consisted of an anaerobic digestion unit, a solid–liquid separation system, and a biological N removal process. Atmospheric emissions and nutrient losses in water and soil were examined for the environmental assessment, while estimated crop removal and nutrient utilization efficiencies were used for the agronomic assessment. The integrated treatment system achieved 49% removal efficiency for total solids (TS), 40% for total Kjeldahl nitrogen (TKN), and 41% for total phosphorous (TP). A surplus of 58kWh/t of treated manure was achieved considering the electricity produced by the biogas plant and consumed by the treatment plant and during transportation of raw and treated manure. A profit of 1.61 €/t manure treated and an average reduction of global warming potential by 70% was also achieved. The acidification potential was reduced by almost 50%. The agronomic use of treated manure eliminated the TKN surplus and reduced the TP surplus by 94%. This collective integrated treatment system can be an environmentally and economically sustainable solution for farms to reduce N surplus in intensive livestock production areas.

“…The process was monitored for two years (1/1/2014-31/12/2015) and data about the amount of manure treated, the characteristics of the manure in the different stages and energy consumption were determined based on García-González et al [25]. The monitoring activity included the transportation of manure to and from the treatment plant in order to assess the energy and emissions associated with the operation.…”

Collective manure processing facilities to reduce nutrient loads and produce renewable energy are often proposed as feasible solutions in intensive livestock production areas. However, the transferring of effluents from farms to the treatment plant and back to farms, as well as the treatment operations themselves, must be carefully evaluated to assure the environmental sustainability of the solution. This study evaluated the global warming potential (GWP) and acidification potential (AP) of a collective treatment plant for bioenergy production and nitrogen removal as an alternative strategy to conventional on-farm manure management systems. Two manure management scenarios were compared: manure management on individual farms and management by a collective treatment plant. Data were collected at a collective processing plant and at the individual farms of the consortium to estimate emissions of CO2, CH4, N2O, NOx, NH3 and SO2. The plant receives manure from 21 livestock production units, treating 660 tonnes day−1 of manure. The GWP and AP indicators were calculated to evaluate the potential impact of the two management solutions. The collective solution reduced both GWP (−52%) and AP (−43%) compared to manure management separately by each farm. Further improvement might be obtained in both indicators by introducing mitigation techniques in farm manure storage and manure application to soil.
