Improving Life Cycle Assessments for Sustainable Solid Waste Management Decision Making

Dr. Wendy Wang developed a state-of-the science life-cycle assessment (LCA) model for a regulatory compliant municipal solid waste landfill in the US. She found that while landfill gas emissions contribute 50–99% to global warming, ozone depletion, and smog impacts, the production of materials required for construction and operation of the landfill contribute 68–75% to toxicity impacts. This is important because many landfill LCAs do not fully consider the materials used in the landfill, and this result shows that their inclusion is critical for understanding toxicity impacts from landfills. This regulatory compliant landfill LCA model has been implemented to investigate the impact of plastics’ biodegradabilities as disposed in landfills on GHG emissions. Additionally, the first comparison of the effects of using dynamic versus static global warming potentials (GWPs) on estimates of the global warming impacts associated with long-term emissions from landfills. It was found that in general using dynamic 100-year GWPs will not change alternative rankings compared to static GWPs. However, that does not hold when using 20-year GWPs, and the dynamic GWPs show the change in radiative forcing over time in a way that static GWPs inherently cannot. Wendy developed methods for reducing the time, costs, and data required to develop meaningful LCAs of solid waste management systems. This streamlining LCA framework helps facilitate the use of LCAs proactively in the early design and planning stages of solid waste strategy development where most of the decisions related to environmental sustainability occur. The streamlined framework proved to reach similar conclusions to full life-cycle assessments while substantially reducing the time and data requirements of conventional LCAs.

Interpreting the seasonality of atmospheric methane

The amount of methane (CH4), a greenhouse gas with a global warming potential 80 times that of CO2 on 20-year time scales, has been growing in Earth’s atmosphere during the last decade, and scientists disagree about which methane sources and sinks are responsible for the growth. One clue into understanding methane’s sources and sinks is their seasonality – their month-to-month cycles that happen every year. Measurements of atmospheric methane taken at the Earth’s surface and using satellite instruments show a steep increase each summer in the Northern Hemisphere that is not replicated when methane is simulated in a global chemical transport model, indicating missing information about source and sink seasonalities. To investigate, we use the GEOS-Chem global chemical transport model to simulate 24 representations of methane’s largest source, emissions from wetlands, and 22 representations of its largest sink, chemical loss by the hydroxyl radical (OH). We find that OH is unlikely to cause the summer increase and model bias. Instead, global wetland emissions drive the summer increase through their amount, spatial distribution, and seasonal cycles. We suggest that these characteristics are linked to the underlying mechanisms determining wetland area and methane production in wetland models. The results unveil the role of global wetlands in driving methane’s seasonality and inform analyses of methane’s long-term trends.

“Two-Eyed Seeing" investigation of the air quality and health concerns of Pictou Landing First Nation, Nova Scotia, Canada - a story of environmental injustice.

Study indicating impacts of a pulp and paper mill’s effluent dumping into the estuary of Boat Harbor (BH) and Pictou Landing First Nation (PLFN), near Nova Scotia, Canada. The project in 2013 used a Two-Eyed seeing approach (combination of traditional and Western wisdom and science) to investigate the environmental health concerns of PLFN to demonstrate how air quality around the BH and PLFN were significantly impacted.

URBAN INFILL BROWNFIELDS REDEVELOPMENT TRENDS

Virtual via Zoom

Tuesday, March 15

Hosted by the RTP Chapter 

Learn the latest on Brownfields redevelopment trends both at the North Carolina and Federal level. This presentation will provide a brief overview of the Brownfields redevelopment process and associated regulatory requirements to support safe reuse of contaminated properties. Now that a number of the easier less-contaminated properties have been purchased and redeveloped, a trend toward redevelopment of technically challenging urban infill sites has emerged including landfills and highly contaminated sites. These sites have been dormant and underutilized for years, have raised safety concerns and have impacted local communities. Learn how these properties are redeveloped to be protective of human health and the environment and to support economic growth. Case studies will be used to highlight the Brownfields redevelopment process, including how cleanup strategies and technical approaches are developed and implemented to promote safe reuse of Brownfields sites and the regulatory requirements behind the process.
