“…On the other hand, various systems have been proposed to reduce NH 3 emissions from livestock farms [2]. Several relevant aspects of these measures were investigated in early studies, such as the theoretical effectiveness on emission reductions [3][4][5], energy use efficiency [6,7], and economic impact to the farms [8]. However, information on the NH 3 reduction efficiency of these systems in practice is still limited due to insufficient or unreliable monitoring.…”

Ammonia emissions are an important issue in livestock production. Many mitigation measures have been proposed in order to reduce the environmental impact of livestock farms, and reliable field measurements are required to evaluate the amount of released or reduced ammonia while applying these measures. Following the guideline of the Verification of Environmental Technologies for Agricultural Production test protocol, five commercially available gas analysers, i.e., INNOVA 1314, Picarro G2103, Rosemount CT5100, Gasmet CX4000, and Axetris LGD F200-A, were validated as alternative methods to the wet-chemistry method (reference method) for measuring ammonia in livestock houses. High correlations ( r > 0.99 ) were found between the analysers and the reference method. The measurement errors of the tested analysers were below 2 ppmv or 10%. Equivalence to the wet-chemistry method was demonstrated for the INNOVA and Rosemount analysers without a recalibration and for the Picarro and Axetris analysers with a recalibration. The Gasmet analyser was seemingly subjected to an interference from carbon-dioxide and, after compensating for the cross-sensitivity, the equivalence to the wet-chemistry method could also be demonstrated. Calibration curves that were based on a certified gas cylinder were inconsistent with that based on wet-chemistry measurements, which suggested that field calibration might be necessary for optimal measurement accuracy.

“…In addition, the sensitivity analysis showed that the contribution of other economic activities to nitrogen deposition must be taken into account, since the level of background deposition will affect the compensation area of single power plants. Strong emission reduction measures, which may be taken by for example the agricultural sector (Van der Heyden et al, 2016), can result in a strong reduction of this background deposition. The affected nature areas by single power plants will not change, but compensation areas and associated costs may be reduced considerably.…”

Environmental reporting by companies is becoming increasingly important for measuring sustainability performance, but biodiversity impacts are still largely unaccounted for due to the complexity of assessing such impacts. Energy production by power plants causes nitrogen emissions that may affect nature areas. To assess the impact of power plants on the biodiversity of Natura 2000 areas and to estimate compensation costs, we developed an analytical framework and applied it to four single power plants in the Netherlands. These plants differed according to production capacity and fuel source (natural gas and biomass). The plants affected between 77 and 537 km 2 of Natura 2000 nature areas. To estimate cost of biodiversity loss and compensation, three approaches were applied: costs of restoration, 'insetting' costs incurred by creating new nature areas within the current Natura 2000 network, and offsetting costs, including land purchase of former agricultural land. Depending on the nitrogen exceedance levels of vegetation, compensation areas ranged between 6.5 and 23.6 ha. The estimated total cost per power plant varied from V 38,430 to V 1,753,261 annually. Depending on the cost method applied, biodiversity cost of energy production by single power plants ranged from 0.06 V.MWh À1 to 1.65 V.MWh À1. This cost largely depends on the type and location of the vegetation affected, which indicates that a spatial analysis is needed to measure the biodiversity footprint of business operations in environmental reporting.

“…The reported descriptions of air cleaning systems such as air scrubbers and biofilters, have used wet packing media to purify the air from livestock buildings. Their filters remove pollutants (PM, NH 3 , H 2 S, and others) from outlet air through absorption in the media, followed by chemical and/or biological conversions and the removal of end products [104].…”

Mitigation Strategies of Air Pollutants for Mechanical Ventilated Livestock and Poultry Housing—A Review

et al. 2022

The fast development of large-scale intensive animal husbandry has led to an increased proportion of atmospheric pollution arising from livestock and poultry housing. Atmospheric pollutants, including particulate matter (PM), ammonia (NH3), hydrogen sulfide (H2S), and greenhouse gases (GHG), as well as other hazardous materials (e.g., gases, bacteria, fungi and viruses), have significant influences upon the local atmospheric environment and the health of animals and nearby residents. Therefore, it is imperative to develop livestock and poultry housing mitigation strategies targeting atmospheric pollution, to reduce its negative effects on the ambient atmosphere and to promote sustainable agricultural production. In this paper, we summarize the various strategies applied for reducing outlet air pollutants and purifying inlet air from mechanical ventilated livestock and poultry housing. This review highlights the current state of knowledge on the removal of various atmospheric pollutants and their relative performance. The potential optimization of processes and operational design, material selection, and other technologies, such as electrostatic spinning, are discussed in detail. The study provides a timely critical analysis to fill the main research gaps or needs in this domain by using practical and stakeholder-oriented evaluation criteria.
