NUTRITIONAL STRATEGIES FOR IMPROVING THE SUSTAINABILITY OF SWINE FARMING
… impact, plays a significant role due to its nitrogen emissions, its high consume of feedstuffs in competition with human consumption, such as cereals, and its high reliance on soybean products, an ingredient characterized, especially in Europe because of the high amount imported, by a high …

The feasibility of a commercial-scale recirculating aquaculture system integrating sea urchins (Tripneustes gratilla) and seaweed (Ulva)
… allow for the accurate prediction of T. gratilla nitrogen emissions. The literature indicates that production of various urchin species is reduced when cultivated in deeper baskets, in contrast to shallower baskets. Thus, if and why basket depth has this effect was investigated and an ideal basket …

Emissions and Chemistry of Reactive Nitrogen in Wildfire Plumes
Wildfires are an important source of reactive nitrogen species to the atmosphere, accounting for approximately 25% of global annual nitrogen oxides (NOx). Emissions of wildfires are highly variable depending on factors such as fuel types and burning conditions, yet in situ measurements and …

Continuous aerobic processing of piggery effluent: a new approach to quantifying the fate of the nitrogen component
… for pig slurry, to quantify the various forms of nitrogen entering and leaving under different conditions. The purpose of this was to assess the effect of such treatment conditions in terms of the amount of polluting forms of nitrogen generated from the slurry. A laboratory scale reactor (designed …

Bioproducts and environmental quality: biofuels, greenhouse gases, and water quality
… is one oft-proposed solution to reduce GHG emissions because the feedstocks capture carbon, offsetting at least partially the carbon discharges resulting from use of the products. However, several life cycle analyses point out that while biofuels may emit less life cycle net carbon emissions …
