EREF Awards Three Projects with Grants for Solid Waste Research

The research that is conducted through these grants goes hand-in-hand with EREF’s mission to further advance sustainable solid waste management practices.

The Environmental Research & Education Foundation (EREF) Board of Directors has announced three new research grants for solid waste research in 2016. The research that is conducted through these grants goes hand-in-hand with EREF’s mission to further advance sustainable solid waste management practices.

The grant recipients are:

Assessing Accuracy of Tracer Dilution Measurements of Methane Emissions from Landfills with Wind Modeling

Investigators: Paul Imhoff, University of Delaware and Fotini Chow, University of California, Berkley

Award Amount: $93,069

The main objectives of this research are to:

  1. Develop a 3D land-atmosphere model for the Southeastern U.S. landfill, validating the model with tracer gas data in the field.
  2. Use this new model to simulate methane emissions and estimate measurement error for prior daytime field measurement campaigns at this site.
  3. Use the model to estimate emissions at night and during periods when field measurements were not performed.
  4. Assess the representativeness of methane emission data from limited measurements for calculating year-round methane emissions for any given landfill.

Mineralogy Optimization for Metal and Chloride Immobilization in Co-Disposed Flue Gas Desulfurization Brines and Bituminous Coal Fly Ash

Investigator: Ching-Hua Huang, Georgia Institute of Technology

Award Amount: $195,917

This project aims to optimize the immobilization of selenium and chloride in the co-disposed concentrated FGD brines and bituminous CFA by solidification/stabilization. Immobilizing these compounds will rely on chemical processes and the potential effects of temperature, pH, calcium oxide content, temperature and reactive aluminum oxide will be evaluated. The long- and short-term stability of the immobilized compounds will be tested using leaching tests under various conditions.

Developing Strategies to Recover and Treat Nutrients in the Landfill Leachate

Investigator: Ramesh Goel, University of Utah and Debra Reinhart, University of Central Florida

Award Amount: $141,704

The objectives of this project are to:

  1. Determine the optimal conditions to recover nitrogen and phosphorus from the anaerobic digester centrate and landfill leachates using chemical precipitation in the form of struvite.
  2. Characterize the recovered struvite to determine its fertilizer quality and check for the presence of other metals and hormones.
  3. Initiate and operate a two-stage treatment process to remove carbon from the residual liquid waste obtained after nutrient recovery.
  4. Conduct life cycle analysis of the proposed nutrient recovery and treatment scheme.
