Methane monitoring and more technologies for landfills. This image shows a drone path and a plume from a satellite, with details of the problematic wells.

 

The U.S. Environmental Protection Agency USEPA Landfill Technology Workshop will highlight the state of advancing technologies, including their ability to detect and quantify methane and discuss how these technologies might fit into a regulatory framework. SCS Engineers’ Phil Carrillo will participate in the workshop and experts Melissa Russo, Andy Sheppard, and David Greene will be available to answer questions.

Registration is closed, but if you were not able to register before the deadline, please contact Nan Albaladejo by email () or by phone (703-705-4438) to be registered manually (if space is available). Since the workshop appears fully booked, below are some resources regarding the proven and emerging landfill methane detection and measurement technology that could work for you and the challenges they help address.

Compounded by rising labor costs and regulations, the three major challenges for landfill owners and operators are mitigating toxins, liquids, and greenhouse gases. Landfills and solid waste operations across North America use drones and remote monitoring and control applications to optimize operations and address these major challenges, including surface emissions monitoring.

Combine sensors with SCS drone-based technologies to monitor landfill gas (LFG) emissions and detect leaks, eliminating a significant portion of the manual effort from quarterly compliance while performing operations more safely and accurately. Captured emissions data is useful for optimizing well fields, tackling odor issues, and quantifying emissions for renewable natural gas projects.

In the videos below and USEPA Landfill Technology Workshop, a 2-day meeting sponsored by the agency focuses on developing (and benefits associated with) advanced methane monitoring technologies applied to landfill monitoring. SCS Engineers expert Phil Carrillo will participate in the Technology Panel Discussion, and expert Melissa Russo will attend and be available to answer questions.

USEPA Landfill Technology Workshop covers these topics as follows,

  • How does your method compare to EPA Method 21? How does it demonstrate an advancement over the current approach? Could it be used instead of EPA Method 21 for monitoring surface emissions?
  • How do you manage variable winds and other complex environmental conditions?
  • How do you manage complicated terrain?
  • Is your resolution sufficient to distinguish between allowable emissions (working face) and those that are not allowed?
  • Has the technology been tested for any potential chemical interferences from other species present in emissions from landfills, and if so, what were the results?
  • What are the similarities between advanced technologies that detect methane from landfills and those employed in the oil and natural gas production field? Are there significant differences that EPA should be aware of?
  • How could this technology be incorporated into the current NSPS and EG? How could the technology be used to reduce emissions from the landfill?
  • What are the required environmental conditions (wind conditions, topography, etc.) for your technology to be useful?
  • Explain the financial feasibility of landfill emission monitoring technology.
  • What are the results of the uncertainty analysis of the technology?

Free, on-demand video resources

Drones, sensors, LiDAR, weather, and IoT, our landfill technology experts demonstrate how technologies work together to investigate gas collection and control systems (GCCS), liquids, airspace, stormwater, weather, wellheads, flares, pumps, temperature, and other equipment. Technology can help reduce labor and reaction time by automating what once took many hands in the field.

Video: 2024 Landfill, RNG, and Compost Monitoring Technologies Based on successful client installations, the SCS RMC team shows how landfill and facility owners/operators can respond in hours to satellite imagery of methane plumes, adjust operations to control odors based on weather conditions and collect methane emissions data in a fraction of the time it takes with traditional ground monitoring.

Video: Optimizing Landfill Technologies for Greater Efficiencies Part 1. Using drones and GIS integration for managing landfill gases and liquids. These combinations of technologies can even help you see underground conditions. It’s like having x-ray vision to manage GCCS and support leachate management while maximizing well-field pull.

Video: Optimizing Landfill Technologies for Greater Efficiencies Part 2. Panelists explain which technology is best for what and when integrating these technologies better serves your purpose and budget.

SCS Engineers Vice President, Betsy Powers, is one of the industry leaders who will teach at the University of Wisconsin’s Solid Waste Landfill Design Short Course, March 27-30, at UW campus in Madison.

Learn about the critical factors of solid waste landfill design, operations, evolving industry issues, and economics. Learn from expert and diverse course faculty (top-flight researchers, owners at the cutting edge of evolving practice, industry experts). Get a firm grasp of the background and design specifics to compete in this industry, including industry-leading information on the principles and practices of solid waste landfill development, design, construction, operations, and management. Understand practical emerging technologies including:

  • financial management of solid waste systems and airspace management
  • polymer-based bentonite composites in geosynthetic clay liners
  • landfill gas containment and management for emission control and regulatory drivers
  • value-added design of gas-to-energy and gas-to-fuel projects
  • waste relocation and expansion
  • evolving issues with “hot” landfills
  • the latest in geosynthetic products for geoenvironmental engineering
  • performance-based and life cycle-based design

Betsy Powers will teach about Landfill Drainage and Runoff Control on Day 3 in the Evolving Topics in Landfill Management, Operations, and Risks Track.  Betsy will cover runoff amounts; open channel flow and culverts; and sedimentation/detention basins.

This course will guide you through the development process of a successful solid waste landfill, from cradle to grave. Industry experts will share critical factors and insights. Interactive discussion and idea exchange will be emphasized. It is intended for the gamut of industry professionals from civil engineers and landfill designers to landfill owners and operators, as well as local, county, and state regulatory agencies; public works professionals; facility managers; contractors and estimators; geosynthetic manufacturers and reps; planners; and everyone in between.

Qualifies for CEU and PDH credits.
