In the ongoing narrative of environmental conservation, few adversaries are as concerning as methane gas emissions from landfills. This potent greenhouse gas poses a substantial threat to both our climate and community health, demanding immediate attention and sustainable solutions.
Landfills contain several different gases and volatile organic compounds (VOCs) caused by the breakdown of waste, with methane and carbon dioxide making up over 90% of them (health.ny.gov). Once waste breaks down and forms landfill gas and particulates, it can potentially spread to nearby buildings or structures through openings like cracks, windows, or ventilation systems and settle in areas of poor ventilation like basements or crawl spaces (health.ny.gov).
Landfill sites have long been recognized as significant contributors to methane emissions, and from advanced gas extraction technologies to precision measurement instruments, the toolkit for combating methane emissions is expanding.
Moreover, as methane is a flammable and combustible gas, it is important to ensure adequate flow to prevent build-up within the landfill or nearby buildings.
Using a flow sensor, like the Dwyer Instruments Series DS, and ensuring an efficient and controlled airflow, not only aids in the responsible extraction of methane but also prevents the accumulation of poisonous gases, safeguarding both the environment and public health. This solution features a 304 stainless steel sensor Pitot tube, designed to resist corrosion in the harsh landfill environment. Pitot tubes are an extremely reliable, proven technology that have been an industry staple for many years. When combined with a differential pressure gage or transmitter, it is possible to monitor the airflow and take corrective action if needed.
We suggest pairing the Series DS with one of the following:
- Series 2000 Magnehelic® Gage
- Series 3000MR Photohelic® Switch/Gage
- Series 4000 Capsuhelic® Gage
- Series MSX Magnesense® Transmitter
- Series 3100D Explosion-Proof Transmitter
- Series DHC Digihelic® Controller
In addition to monitoring the flow of landfill gases, it is also necessary to ensure that dangerous particulates do not build up in neighboring buildings (NIH.gov). Utilizing a particulate matter transmitter, such as the Series PMI, allows for the effective detection and monitoring of VOCs and other particulates. The Series PMI can measure particles as small as 0.3 µm, making it an essential component of any indoor air quality monitoring system.
