Senior Environmental Engineer
Why I am a member of the IWWG?
I am responsible for US EPA research which has greatly benefitted from the connections that I have made through the IWWG. Leveraging expertise and funding leads to more sound science and more impactful research products. The IWWG fosters an environment where research is discussed in an independent forum not centered around promoting any one business or technology. Early in my career, I was aware of the benefit of leveraging international science and expertise. I tended to look outside of traditional approaches, for example using of life cycle assessment to evaluate solid waste management. I sought kindred spirits that were interested in detailed dialogue to develop a methodology that provides a more holistic and credible approach to evaluating solid waste management with the goal of optimizing energy and resources. Now there are tools including our Municipal Solid Waste Decision Support Tool (MSW DST) to evaluate the economic and life-cycle environmental tradeoffs to collect, transport, recover, process, recycle, compost, digest, combust, and landfill waste. These tool helps communities develop more sustainable programs for materials management.
I work in other areas as well including quantifying emissions (especially fugitive methane emissions). Some of the very best sessions anywhere in the world are the sessions at the International Waste Management and Landfill Symposium on quantifying landfill gas emissions. There are always several sessions on this topic with top researchers in the world presenting their work. It is not uncommon to see full sessions even during the 6-8pm time slots. I am grateful to those presenters willing to share their experiences and failures where we can all learn from. The IWWG promotes an open and respectful dialogue for scientists and engineers to present their research. And there is time for questions either during the sessions or on the coffee (or tea) breaks.
I am also work to develop and validate leaching methods (i.e., Leaching Environmental Assessment Framework) that will eventually be the primary method for determining the leaching of constituents of potential concern from waste disposal (on land), waste treatment, and “beneficial” use of industrial by-products including coal ash. Although we want use of “waste” materials, our primary focus is protection of human health and the environment. One of the principals on this research is Hans van der Sloot who has given many workshops at IWWG events on leaching. The methods are now in use in the U.S., Europe, China, Australia, and Israel.
Throughout my research, I have benefitted from IWWG colleagues and the symposia that brings us together. It has been an invaluable connection for me in vetting ideas and getting critical feedback on our research.
I am proud to be part of the IWWG and to serve on the board.
