How Scentroid’s CTair Assisted Landfill in Environmental Litigation

Scentroid’s CTair ambient air quality monitor and GD600 gas dilution calibration device played a pivotal role in a recent court case involving a landfill in Michigan. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) filed a lawsuit against the landfill, alleging that the company did not comply with government regulations and standards for hazardous air pollutants in municipal solid waste landfills. Among other things, the lawsuit claimed that the landfill failed to control methane concentration, which could have been a serious risk to public safety.

As part of the suit, the landfill was required to employ six Scentroid CTair units as part of their Perimeter Emissions Monitoring Program. These devices continuously monitored landfill emissions, ensuring pollutants remained within government regulations. By utilizing Scentroid’s devices, the landfill demonstrated its commitment to environmental responsibility and avoided costly litigation.

Scentroid’s CTair ambient air quality monitor is a highly advanced device that provides accurate and reliable air quality data.

Breaking: Scentroid DR1000 Used in Landfill Methane Study

A recent study was conducted by the Michigan Department of Environment, Great Lakes, and Energy which utilized the Scentroid DR1000. The study aimed to investigate the impact municipal solid waste landfills have on atmospheric methane. This remains a major contributor to global warming. Several methods of tracking methane were currently deployed – however, they held an uncertainty of approximately 50%.

For this project, the Scentroid DR1000 was equipped with a Tunable Diode Laser Spectrometer with a methane sensor (lower detection limit of 0.4 ppm). The sampling rate frequency was maintained at 2Hz with a resolution of 10 ppb. The DR1000 was also equipped with a GPS to receive data from several global navigational satellite systems. An onboard pressure sensor was included to measure altitude. While flying, the DR1000 recorded position, altitude, temperature, humidity, and ambient methane concentration.

“The quantification of landfill gas emissions requires measurements not only of ambient methane concentrations, but also of meteorological parameters such as the prevailing wind speed and direction, temperature, and pressure.”

Results found that emissions from both the active landfill face and the leaking gas collection systems are important sources of landfill emissions. This was a surprising development – Reported methane emissions from landfills typically do not account for contributions from the active face. Thus, greenhouse gas emission inventories are unfortunately downplaying landfills’ role in climate change.

Scentroid’s SM100 used in Odour Monitoring Pilot Project

What happens to a thriving city when faced with a near-insurmountable odour nuisance? They request Scentroid’s assistance and our SM100 Odour Monitoring technology!

The City of London, Ontario is a bustling metropolis of over 500,000 residents, nestled in Southwestern Ontario. London is a regional centre of both healthcare and education. It serves as home to Western University and several hospitals and research facilities. Its economic activity is dominated by education, medical research, and information technology.

There’s only one slight problem. In the city’s south end lies a landfill, biogas facility, and a composting facility, all within 5-15km of each other. It can pose quite the odour problem, especially during warmer summer months.

From 2007 to 2017, the Ontario Ministry of the Environment received over 1500 complaints regarding odours emanating from these facilities. Through a joint project between StormFisher Environmental, OrgaWorld Canada, and the city of London, Scentroid was contacted. We were requested to provide training and the SM100 Odour Monitoring device to assist with tracking the odour nuisance.

Scentroid’s SM100 Odour Monitoring allows users to accurately quantify ambient odour strength in OU/m3. It offers an easy-to-use cost-effective alternative to estimating odour strength or using odour measuring laboratories.

The SM100 draws a sample of ambient air via Venturi pump and dilutes it using odourless air from a tank. The operator uses an adjustable sliding valve to control the ratio of fresh to ambient air, which is then fed through a sliding valve into the PTFE face mask. The valve position indicator displays the sample strength (Dilution to Threshold or OU).

The Environmental Protection Act (EPA) gives the Ministry of the Environment, Conversation and parks the authority to respond to odour concerns. The City is planning on deciding the next steps in odour management based on the monthly results.

Reported Increase in Nitrogen Based Fertilizers

Nitrogen based fertilizers have always been an easy solution with farming. They are not only incredibly effective, but they are also readily available and a cost-effective method of enhancing crops. Unfortunately, Nitrous Oxide (N₂O) is created as a bi-product of these fertilizers. N₂O is 265 times more effective at trapping heat in the atmosphere than carbon dioxide. This results in it contributing to the depletion of our ozone layer. In a paper published recently in Nature Climate Change, global emissions are higher and growing faster than are being recorded.

With the current level of technology available at hand, it’s important that we stay vigilant. We have to monitor the weight of our own ecological footprint. Scentroid carries an advanced non-dispersion infrared Nitrous Oxide sensor. We can help monitor your facility, plot the best course of action, and connect you with the latest mitigation solutions – before the regulatory framework is placed on your operation. Remember, sudden change can be both difficult and expensive. Be proactive, not reactive – Let’s figure out the best solution for you, together.

What’s that Smell? Ask the Scentroid Odour Experts!

Case Study: A feedlot and compost facility in rural Alberta had been receiving odour complaints from nearby residents. Located within the surrounding community on the outskirts of a major city, the feedlot’s complaints were numerous and collected quickly. Over a short period of time, the local Government demanded immediate action or the feedlot may face potential closure.

Upon being contacted, Scentroid completed an immediate odour impact assessment. Employing the use of the scentroid SM100 and odotracker, olfactometric and analytic measurements throughout the site were taken. Data points were collected within the interior of the site and along the fence line. This allowed Scentroid to model the data, which displayed the severity and extent that the odour air plume could extend. This resulted in a staggering 20km radius. The client had decided that they wanted to monitor the facility continuously, resulting in the use of 2 SL50 units. Scentroid directed the facility where to install the units to ensure the most ideal location for further data mining.

As the city council had sought the termination of the facility, Scentroid had served as expert witnesses. This ensured the odour situation would be contained and monitored and is within reasonable limits. Our team also provided a wealth of knowledge regarding mitigation solutions to manage the odour in order to minimize complaints.

Scentroid DR1000 Pollution Monitoring Lab is Presented at AQ Exhibition in South Korea

Unmanned aerial vehicles are no longer a thing of the future. They are part of our everyday life.

KJN Technologies recently presented the Scentroid DR1000 Pollution Monitoring Lab features, applications, and data quality at the Air Quality Exhibition of South Korea.

Traditionally, ground-based monitoring usually conducts air quality assessments. However, manned aircraft and satellites continue to do so today. In addition, performing fast, comprehensive data collection near pollution sources is not always feasible. This is because of the complexity of sites, moving sources or physical barriers.

With the DR1000 Pollution monitoring lab, All that is required is to fly the drone up to the stack height, and full information including all sensors reading, humidity, temperature and GPS position will be sent to the ground station and the cloud-based monitoring software automatically.

Equipping small unmanned aerial vehicles (drones) with the Scentroid DR1000 and sensor technology allows the full utilization of air quality monitoring. They offer new approaches and research opportunities in air pollution and emission monitoring. They also present an opportunity to study atmospheric trends, such as climate change while ensuring urban and industrial air safety.
