A Comparative Sustainability Study For Treatment Of Domestic Wastewater: Conventional Concrete And Steel Technology Vs. Vegetated Sand Beds (Vsb’S) And Their Relative Differences In Co2 Production, Alicia M. Milch
Masters Theses
Conventional wastewater treatment in the U.S. is an energy dependent and carbon dioxide emitting process. Typical mechanical systems consume copious amounts of energy, which is most commonly produced from fossil fuel combustion that results in the production of CO2. The associated organic load is also metabolized by microorganisms into CO2 and H2O. As the desire to reduce CO2 output becomes more prominent, it is logical to assess the costs of conventional treatment methods and to compare them to alternative, more sustainable technology. Vegetated Sand Bed (VSB) and Reed Bed (RB) systems are green technologies …
Calculating The Campus Nitrogen Footprint, Allison Leach, Jennifer Andrews
Calculating The Campus Nitrogen Footprint, Allison Leach, Jennifer Andrews
NECSC Conference 2015
Many universities interested in sustainability have calculated their carbon footprint. The carbon footprint is well-established and understood: it tells us how much carbon dioxide and other greenhouse gases are emitted to the atmosphere as a result of university activities. While important, this calculation addresses just one part of a university’s environmental impact. Universities that want to expand their approach to sustainability can now also calculate their nitrogen footprint.
Nitrogen footprints connect entities, such as individuals or universities, with the reactive nitrogen (all species of nitrogen except N2) lost to the environment as a result of their activities. While necessary to …
