Four Amazing YPs Take Us On A Landfill Technology Journey

March 26, 2021

 

David Hostetter, Sam Rice, Joy Stephens, and Chris Woloszyn take us on a landfill technology journey in their recent EM Magazine article. It is amazing what these YPs are developing and implementing nationwide. The future looks bright!

 

Most equipment data and system data are collected manually for regulatory compliance; this process is time-consuming, expensive, and sometimes dangerous. Consequently, some sites only collect a few data points per day, which may not provide a complete picture of landfill operations. They also contend with the control and maintenance of remote equipment. These YPs explain how they’ve solved these challenges using RMC and SCADA systems.

Field technicians—heavily laden with instruments, printed data collection sheets, logbooks, clipboards, maps, and other gear—spend long days collecting immense amounts of data. Additional labor awaits supervisors and managers as they transcribe, digitize, or otherwise prepare the data for analysis. This team deciphers the information recorded on sheets and logbooks, often accompanied by leachate stains, mud spatters, and water damage. GIS provides a low-cost way to streamline data collection, track progress, visualize task completion, and analyze collected data to deliver an overview of the landfill’s status.

Beyond cameras, various sensors can be attached to a drone. These sensors range from infrared cameras to LiDAR sensors to gas identification tools. One such tool helps identify the presence of methane leaking out of a landfill. A drone pilot can maneuver over the entire landfill, sniffing out methane leaks and seeking out poor landfill-cover integrity, all in a matter of hours. Drones collect methane data quickly and accurately without the need for traversing the ground on foot or by vehicle.

Integration of additional automatic and manual data collection methods, such as quarterly or annual drone flights, RMC systems, and remotely monitored and controlled wellheads, provide a comprehensive view of landfill performance and overall condition. UAVs or drones allow for safe inspections, quick data gathering, and lower operating costs.

Advice from the Field: Plan for and design a landfill gas collection system with particular attention to landfill bottom liners.

November 21, 2017

We continue SCS’s Advice from the Field blog series with guidance from an article in MSW Magazine by Daniel R. Cooper, Jason Timmons, and Stephanie Liptak.

Planning a landfill gas collection system before collection is required can increase the long-term benefits for multiple stakeholders.

The authors of a recent article in MSW Management Magazine present engineering ideas that provide for more efficient construction of a GCCS.  Gas system operators will benefit by having fewer pumps to operate and maintain and shallower headers that are more easily accessible. Odor management will be easier along with other benefits.

Read the full article here to learn about the design elements for maximizing long-term benefits, impacting: bottom liners, location of the blower/flare station, leachate risers, extraction well targets, and external header piping.
