The Role of Landfills in US Sustainable Waste Managament
Navigating the Academic Job Search for Environmental Engineers: Guidance for Job Seekers and Mentors
This research sought to understand the behavior of engineered nanoparticles in landfill leachate by examining the interactions between nanoparticles and leachate components. The primary foci of this paper are the effects of ZnO
TiO2
and Ag nanoparticles on biological landfill processes and the form of Zn
Ti
and Ag in leachate following the addition of nanoparticles. Insight into the behavior of nanoparticles in landfill leachate was gained from the observed increase in the aqueous concentrations over background for Zn
Ti
and Ag in some tested leachates attributed to leachate components interacting with the nanoparticle coatings resulting in dispersion
dissolution/dissociation
and/or agglomeration. Coated nanoparticles did not affect biological processes when added to leachate; five-day biochemical oxygen demand and biochemical methane potential results were not statistically different when exposed to nanoparticles
presumably due to the low concentration of dissolved free ionic forms of the associated metals resulting from the interaction with leachate components. Chemical speciation modeling predicted that dissolved Zn in leachate was primarily associated with dissolved organic matter
Ti with hydroxide
and Ag with hydrogen sulfide and ammonia; less than 1% of dissolved Zn and Ag was in the free ionic form
and free ionic Ti and Ag concentrations were negligible.

Emerging contaminants: Nanomaterial fate in landfills
This research sought to compare the effectiveness of three landfill enhanced treatment approaches aimed at removing releasable carbon and nitrogen after anaerobic landfilling including flushing with clean water (FB 1)
leachate recirculation with ex-situ treatment (FB 2)
and leachate recirculation with ex-situ treatment and in-situ aeration (FB 3). After extensive treatment of the waste in the FB scenarios
the overall solids and biodegradable fraction were reduced relative to the mature anaerobically treated waste. In terms of the overall degradation
aeration did not provide any advantage over flushing and anaerobic treatment. Flushing was the most effective approach at removing biodegradable components (i.e. cellulose and hemicellulose). Leachate quality improved for all FBs but through different mechanisms. A significant reduction in ammonia–nitrogen occurred in FB 1 and 3 due to flushing and aeration
respectively. The reduction of chemical oxygen demand (COD) in FB 1 was primarily due to flushing. Conversely
the reduction in COD in FBs 2 and 3 was due to oxidation and precipitation during Fenton’s Reagent treatment. A mass balance on carbon and nitrogen revealed that a significant fraction still remained in the waste despite the additional treatment provided. Carbon was primarily converted biologically to CH4 and CO2 in the FBs or removed during treatment using Fenton’s Reagent. The nitrogen removal occurred through leaching or biological conversion. These results show that under extensive treatment the waste and leachate characteristics did meet published stability values. The minimum stability values achieved were through flushing although FB 2 and 3 were able to improve leachate quality and solid waste characteristics but not to the same extent as FB 1.

Evaluation of Leachate Dissolved Organic Nitrogen Discharge on Wastewater Effluent Quality
To understand the applicability of the termination indicators for landfill municipal solid waste (MSW) with low initial lignin content
four different accelerated landfill stabilization techniques were applied to anaerobic landfilled waste
including anaerobic flushing with water
anaerobic flushing with Fenton-treated leachate
and aerobic flushing with Fenton-treated and UV/H2O2-treated leachate. Termination indicators
including total organic carbon (TOC)
ammonia-N (NH4+-N)
the ratio of UV absorbance at 254 nm to TOC concentration (SUVA254)
fluorescence spectra of leachate
methane production
oxygen consumption
lignocellulose content
and humus-like content were evaluated. Results suggest that oxygen consumption related indicators used as a termination indicator for low-lignin-content MSW were more sensitive than methane consumption related indicators. Aeration increased humic acid (HA) and (HA + FA)/HyI content by 2.9 and 1.7 times compared to the anaerobically stabilized low-lignin-content MSW. On the other hand
both the fulvic acid (FA) and hydrophilic (HyI) fractions remained constant regardless of stabilization technique. The target value developed for low-lignin-content MSW was quite different than developed countries mainly due to low residual biodegradable organic carbon content in stabilized low-lignin-content MSW.

Pump and Treat Aerobic Flushing Bioreactor Landfill Project\nConventional landfilling will leave the majority of waste constituents for later release; bioreactor landfilling will leave significantly less
but recalcitrant organics and ammonia remain problematic. The proposed Pump and Treat Aerobic Flushing Bioreactor Landfill (PTAFBL) will reduce the potential for pollutant leaching
dramatically shortening the post-closure care period and reducing the potential for long-term adverse environmental impact. The goal of this proposed research is to define the technological requirements of a PTAFBL as a means of sustainable landfilling of municipal solid waste through laboratory-scale simulation of the process. Results will permit quantification of the economics
pollution reduction potential
and energy consumption of the process in comparison with traditional and bioreactor landfills.\n\nFate of Nanomaterials in Municipal Solid Waste Landfills\nResponsibilities include evaluating the fate of engineered nanoparticles in municipal solid waste landfills and proposal writing. Specific research focus is on the implications of nanomaterials on aerobic and anaerobic landfills processes
speciation of nanomaterials under landfills conditions
and effects of emerging contaminants on leachate treatment.
