The Effect of Phosphogypsum on Reducing CO2, CH4, and NH3 Emissions During Composting of Cattle Feedlot Manure: Comparing Aerobic and Anaerobic Composting Open
Phosphogypsum (PG) amendments have been explored as a strategy to enhance composting efficiency while mitigating greenhouse gas emissions and nitrogen losses. This study investigated the effects of PG at different concentrations (3%, 8%, a…
The Impact of Aerobic and Anaerobic Processes on Gas Emissions During Co-Composting of Specified Risk Materials and Cattle Manure Open
A series of experiments were conducted using a pilot-scale column reactor to investigate the effects of aerobic and anaerobic biological activities on gas emissions during the co-composting of Specified Risk Materials (SRM) with cattle man…

Systematic Literature Review of Ecological Discourse Analysis From 2014 to 2023 Open
One of the crucial foci of contemporary linguistics is upon the complex human-nature relationship within the Anthropocene. An essential methodology of eco-linguistics is Ecological Discourse Analysis (EDA), a field which combines linguisti…
Impedance properties of biomass in support of practical mensuration in rain gardens Open
Impedance microbiology was explored to provide insights into how a sensor that can monitor the growth of bacteria in vegetated bioretention systems (rain gardens) may be designed for in situ , real-time use. The impedance properties of Pse…
Sensors for Biomass Monitoring in Vegetated Green Infrastructure: A Review Open
Bioretention cells, or rain gardens, can effectively reduce many contaminants in polluted stormwater through phytoremediation and bioremediation. The vegetated soil structure develops bacterial communities both within the soil and around t…
Impact of Landfill Gas Exposure on Vegetation in Engineered Landfill Biocover Systems Implemented to Minimize Fugitive Methane Emissions from Landfills Open
Engineered landfill biocovers (LBCs) minimize the escape of methane into the atmosphere through biological oxidation. Vegetation plays a crucial role in LBCs and can suffer from hypoxia caused by the displacement of root-zone oxygen due to…
Natural Source Zone Depletion (NSZD) Quantification Techniques: Innovations and Future Directions Open
Natural source zone depletion (NSZD) is an emerging technique for sustainable and cost-effective bioremediation of light non-aqueous phase liquid (LNAPL) in oil spill sites. Depending on regulatory objectives, NSZD has the potential to be …
Changes in BNR Microbial Community in Response to Different Selection Pressure Open
This study investigated structural changes in microbial community of biological nutrient removal (BNR) in response to changes in substrate composition (ammonium and phosphate), redox condition, and morphological characteristics (flocs to g…
The Efficacy of Whole Oyster Shells for Removing Copper, Zinc, Chromium, and Cadmium Heavy Metal Ions from Stormwater Open
This research investigates the use of a common food waste product for removing four different types of metals typically found in stormwater. Whole, unprocessed oyster shells are explored for use in stormwater management infrastructure that…
A Velocity Meter for Quantifying Advection Velocity Vectors in Large Water Bodies Open
A velocity meter was designed and built in order to meet market needs for an affordable instrument that measures the range of velocity magnitudes and direction experienced in medium- to large-sized water bodies. The velocity meter consists…
A Review of Green Roof Applications for Managing Urban Stormwater in Different Climatic Zones Open
Many regions have turned to low impact development technologies (LIDs), which are implemented to restore the changes in stormwater runoff that have resulted from urbanization. Green roofs are one typical type of LID. Until now, many studie…
Passive evaporation of source-separated urine from dry toilets: UES optimization and dry product accumulation over time Open
A urine evaporation system (UES) was optimized and evaluated in a laboratory by adding 5 L of urine at the same time each day for 65 days. The UES consisted of a wooden box that is open at the front only with tracks for 22 vertically stack…
