Where do you actually measure emissions from a landfill?

Many studies still rely on fixed measurement grids. The problem is that emissions from landfills are rarely evenly distributed. On the contrary, a large share often originates from relatively few hotspots.

If these hotspots are not identified, it is easy to underestimate the total emissions.

At DMR, we have therefore developed a rapid screening method that makes it possible to map methane concentrations across the entire landfill in high resolution. This screening provides a much better basis for:

🔹locating hotspots

🔹 targeting subsequent quantification (e.g., chambers or tracer gas)

🔹 reducing the need for very dense measurement grids

🔹 obtaining a more representative picture of the emissions.

The high resolution also makes it possible to perform very detailed screenings of, for example, biocover windows, where small variations in emissions can be decisive for whether the solution functions optimally.

If you work with landfills or methane emissions and would like to learn more about the method — or have a screening carried out — feel free to contact us at 📞 +45 30225055 / 📩[email protected].

New article in Scientific Reports on carbon dynamics in restored Norwegian peatlands

A new article in Scientific Reports documents the results from a controlled rewetting experiment in Norwegian peatlands:
“Carbon dynamics of a controlled peatland rewetting experiment in the Norwegian boreal zone.”

The study is based on five years of continuous monitoring of CO₂ and CH₄ fluxes from two drained peatlands near Trysil – before and after rewetting (restoration) – and provides important insights into the short-term effects of restoration.

Among the findings:

🔹 The groundwater table increased by approximately 9 cm after restoration

🔹 A short-term increase in both CO₂ and CH₄ emissions was observed

🔹 A new and promising method for counterfactual modelling of restoration effects was tested based on Bayesian Additive Regression Trees (BART)

🔹 The BART modelling estimates that the cumulative flux increased by 80.3 ± 49 g CO₂-C m⁻² and 3.4 ± 0.47 g CH₄-C m⁻² as a result of the restoration (two years after the intervention).

The study highlights how complex carbon processes in wetlands are – and how crucial long-term, field-based monitoring is for documenting the climate effects of restoration measures.

Restoration of wetlands and peatlands is an important climate mitigation measure – but the effects must be measured and documented robustly.

The study was funded by the Norwegian Environment Agency (Miljødirektoratet) and carried out by the University of Oslo, the University of Copenhagen, the Technical University of Denmark, and DMR Miljø og Geoteknikk AS.

⚖️ 🟰 💰DMR continuously works to ensure equal pay ⚖️ 🟰 💰

As an integrated part of the work with DMR’s certified management systems, we focus on the UN’s 17 Sustainable Development Goals, including Goal 5: Gender equality.

In this context, we evaluate the salary level for men and women within DMR every year, for the same job function and the same seniority (years since graduation).

At the beginning of 2026, there are 24 comparable categories covering DMR’s employees. Out of these 24 categories, women receive the highest salary in 12 categories, and men receive the highest salary in 12 categories.

The overall salary difference for employees in the 24 comparable categories is 0.6% (men highest).

This is the 6th year in a row that the salary difference in DMR has been within +/- 1.5%.

We are pleased with the result, although it is simply how it should be :-)

Is your flux chamber measuring the ecosystem – or its own microclimate?

Several studies show that chamber design itself can influence the very processes we aim to measure.

Tall collars and rigid chamber walls can reduce wind speed and turbulence around vegetation and the soil surface.

The result?

• Increased air temperature and humidity inside the chamber
• Altered CO₂ uptake by plants
• Reduced transpiration
• Affected photosynthesis and respiration

These microclimatic effects can introduce systematic biases in measured CO₂, CH₄, and N₂O fluxes – particularly in vegetated systems.

That’s why chamber design is not a detail. It’s critical.
ECOFluX chambers are developed with a focus on:

• Minimal wind shielding
• A low-profile, dynamic chamber principle
• Short closure times – full exposure between measurements
• Gentle closing without mechanical disturbance of vegetation
• Measurements that reflect real ecosystem processes

When documentation needs to be representative – not artifact-driven – design makes the difference.

How accurately do we measure greenhouse gas emissions from wetlands?

Beneath the surface, complex processes control the emissions of CO₂, CH₄ and N₂O – influenced by water table dynamics, temperature, microbiology and plant-mediated transport.

To understand – and document – these emissions, robust and precise field measurements are essential.
ECOFluX chambers are designed specifically for this purpose:

✔️ Direct measurement of greenhouse gas fluxes

✔️ Dual-chamber system enabling light and dark measurements over 24 hours – allowing separation of photosynthesis and respiration

✔️ Engineered to maintain natural conditions inside the chamber (minimal microclimate disturbance)

✔️ High data quality

✔️ Reliable performance in challenging environments

Peer-reviewed documentation: ECOFluX applied for NH₃ emission measurements

In a recent study published in Agriculture, Ecosystems & Environment (Schwennen et al., 2026), automated ECOFluX chambers were used to quantify ammonia (NH₃) fluxes from intensively managed production grassland over a full year.

The study demonstrates that:
🔹 The largest emissions occurred immediately after slurry application

🔹 99.6% of the annual NH₃ emission took place during the growing season

🔹 The total net annual emission was 12 kg NH₃-N ha⁻¹

The results clearly show how crucial high-frequency and continuous measurements are for accurately quantifying real nitrogen balances at the farm level.

NH₃ is a reactive and “sticky” gas that readily adsorbs to surfaces, potentially introducing uncertainty in conventional chamber systems. In this study, the chambers were therefore specially manufactured with PTFE/FEP coating to minimize adsorption and ensure reliable flux measurements.

The use of ECOFluX in a peer-reviewed publication for continuous NH₃ monitoring highlights that the system is not only documented for CO₂, CH₄, and N₂O – but also for advanced nitrogen studies in agricultural systems.

Scientifically validated technology makes the difference when emissions must be documented – not estimated.

Detailed investigation of soil water concentrations in the unsaturated zone

Soil water sampling in the unsaturated zone is a valuable tool used in both research and consultancy — for example to map concentrations of dissolved pollutants transported to groundwater, or to monitor fertilizer concentrations.

Traditionally, sampling depth has been limited because vacuum must be applied to lift the sampled water to a collection bottle at the surface. As part of the available vacuum (maximum ~1000 mbar) is required to extract water from the soil matrix, only the remaining vacuum can be used to lift the water. This typically limits sampling depth to approximately 5–6 meters below surface.

DMR Equipment has overcome this limitation with the new DualTube technique, enabling soil water sampling at depths of up to approximately 40 meters below surface.

The technique is operated using our new automated soil water sampler, which runs on battery power in the field and can be remotely controlled and monitored. This significantly reduces the time required for fieldwork related to vacuum maintenance and sample collection.

💥 Assessment of Explosion Risk from Landfills Using Continuous Logging 💥

It is well known that drops in atmospheric pressure are one of the key factors controlling the transport of methane and carbon dioxide from landfill waste to the atmosphere or into buildings located on landfill sites.

An important element of gas sampling is therefore to ensure that measurements are taken at the right time – when the risk is highest. However, it can be very challenging to plan gas measurements exactly during falling atmospheric pressure.

DMR Equipment has therefore developed a new battery-powered logger for methane and carbon dioxide, which simultaneously records atmospheric pressure on site. The loggers can be placed at critical points and measure, for example, in pore air, beneath buildings, or indoors.

Data are automatically transmitted to DMR’s cloud platform, allowing continuous monitoring and ensuring that your dataset includes periods of low-pressure passages.

If you would like more information about renting the loggers or about the complete solution for measurement and risk assessment, please contact our experts at 📞 +45 30 22 50 55 / 📧 [email protected]
