“…Nuisance complaints related to swine production are generally highest during slurry removal and subsequent land application. The objective of this paper is to report on the emission of NH 3 , H 2 S, and odors before, during, and after slurry removal from two identical deeppit swine finishing facilities located in the midwestern part of the United States over two annual slurry removal events.…”

It is a common practice in the midwestern United States to raise swine in buildings with under-floor slurry storage systems designed to store manure for up to one year. These so-called "deep-pit" systems are a concentrated source for the emissions of ammonia (NH 3 ), hydrogen sulfide (H 2 S), and odors. As part of a larger six-state research effort (U.S. Department of Agriculture-Initiative for Future Agriculture and Food Systems Project, "Aerial Pollutant Emissions from Confined Animal Buildings"), realtime NH 3 and H 2 S with incremental odor emission data were collected for two annual slurry removal events. For this study, two 1000-head deep-pit swine finishing facilities in central Iowa were monitored with one-year storage of slurry maintained in a 2.4 m-deep concrete pit (or holding tank) below the animal-occupied zone. Results show that the H 2 S emission, measured during four independent slurry removal events over two years, increased by an average of 61.9 times relative to the before-removal H 2 S emission levels. This increase persisted during the agitation process of the slurry that on average occurred over an 8-hr time period. At the conclusion of slurry agitation, the H 2 S emission decreased by an average of 10.4 times the before-removal emission level. NH 3 emission during agitation increased by an average of 4.6 times the before-removal emission level and increased by an average of 1.5 times the before-removal emission level after slurry removal was completed. Odor emission increased by a factor of 3.4 times the before-removal odor emission level and decreased after the slurry-removal event by a factor of 5.6 times the before-removal emission level. The results indicate that maintaining an adequate barn ventilation rate regardless of animal comfort demand is essential to keeping gas levels inside the barn below hazardous levels.

Insects as human food; from farm to fork

et al. 2018

View full text Add to dashboard Cite

Over the course of the last few years, the consumption of insects, known as entomophagy, has sparked increasing interest amongst scientists and environmentalists as a potential solution to the inevitable global food security and sustainability issues humans will be facing in the coming years. Despite the fact that insects have been an integral part of over 2 billion people's diet worldwide, the concept of eating insects is still new to Western culture. As a result, there are many unknowns regarding insects as a food source, and this has led to a number of studies and investigations being done in recent years to create more knowledge and awareness around this new concept in the food industry. This review discusses some of the key topics and new developments published over recent years, such as the nutritional benefits, food safety concerns, functional properties, potential product concepts and the current ideas and attitudes towards insects as a food source in Western culture. © 2017 Society of Chemical Industry.
