Danish Researchers invent "methane cleaner": Could become a permanent fixture in cattle and pig barnsIn a spectacular new study, researchers from the University of Copenhagen (Københavns Universitet) have used light and chlorine to eradicate low-concentration methane from air. The result gets us closer to being able to remove greenhouse gases from #livestock housing, #biogas production plants and wastewater treatment plants to benefit the climate. The research has just been published in the journal Environmental Research Letters. The Intergovernmental Panel on Climate Change (IPCC) has determined that reducing methane gas emissions will immediately reduce the rise in global temperatures. The gas is up to 85 times more potent of a greenhouse gas than CO2, and more than half of it is emitted by human sources, with cattle and fossil fuel production accounting for the largest share.A unique new method developed by a research team at the University of Copenhagen’s Department of Chemistry and spin-out company Ambient Carbon has succeeded in removing methane from air."A large part of our methane emissions comes from millions of low-concentration point sources like cattle and pig barns. In practice, methane from these sources has been impossible to concentrate into higher levels or remove. But our new result proves that it is possible using the reaction chamber that we’ve have built," says Matthew Stanley Johnson, the UCPH atmospheric chemistry professor who led the study.Earlier, Johnson presented the research results at #cop28 in Dubai via an online connection and in Washington D.C. at the National Academy of Sciences, which advises the US Government on science and technology.Reactor cleans methane from air.Methane can be burnt off from air if its concentration exceeds 4 percent. But most human-caused emissions are below 0.1 percent and therefore unable to be burned.To remove #methane from air, the researchers built a reaction chamber that, to the uninitiated, looks like an elongated metal box with heaps of hoses and measuring instruments. Inside the box, a chain reaction of chemical compounds takes place, which ends up breaking down the methane and removing a large portion of the gas from air.https://lnkd.in/djPrw4gd#pig #cattle #environmentalsustainability

Agricultural production was a significant contributor to human-driven nitrous oxide emissions in the 2010s, according to the report "Global Nitrous Oxide Budget 2024." This emission, mainly from the use of chemical fertilizers and animal waste on croplands, accounted for 74% of emissions. The study, led by researchers from Boston College and published in the journal Earth System Science Data, sheds light on the environmental impact of agricultural practices.Excess nitrogen from agricultural activities not only leads to soil, water, and air pollution but also has adverse effects on the ozone layer and worsens climate change. It is crucial to address these findings to mitigate the environmental consequences associated with agricultural production. #NitrousOxideEmissions #EnvironmentalImpact #AgricultureResearch

Did you know that nitrous oxide emissions are a major environmental concern, particularly from the agriculture industry? Agricultural Impact: Approximately 75% of all N₂O emissions come from agricultural activities, mainly due to the use of synthetic fertilizers and animal manure. Crop Impact: Excessive N₂O emissions can lead to soil degradation, reducing soil fertility and impacting crop yields, thereby threatening long-term agricultural productivity.What are we doing? PlasmaLeap Technologies is pioneering innovative solutions to address these challenges. By developing cutting-edge technology, we aim to significantly reduce N₂O emissions in #agriculture. Our efforts are poised to be a positive disruption across all regions, driving the Agriculture and #fertiliser industry towards a more #sustainable future and positively impacting the journey to #netzero emissions.ABCScience posted a great article on the topic, written by Peter de Kruijffhttps://lnkd.in/gvdDd5x8

Are there any safety concerns with using nanoparticles in marine environmentsYes, there are significant safety concerns associated with using nanoparticles in marine environments:1- Environmental transformations: Once released into seawater, nanoparticles can undergo rapid transformations due to the high ionic strength, pH, and presence of organic matter. These changes can affect their behavior, fate, and toxicity to marine organisms.2- Aggregation and sedimentation: Nanoparticles tend to aggregate in seawater, which can increase their size and cause them to settle in sediments. This can make them less available to organisms in the water column but potentially more harmful to benthic species.3- Toxicity to marine life: Studies have shown that nanoparticles can cause adverse effects on marine organisms, including cell death, oxidative stress, DNA damage, apoptosis, and inflammatory responses.4- Bioaccumulation: There are concerns about nanoparticles accumulating in marine food chains, potentially affecting higher trophic levels and human seafood consumers.5- Long-term impacts: The long-term effects of nanoparticles on marine ecosystems are still largely unknown, making it difficult to assess their overall environmental safety.6- Regulatory gaps: There is currently a lack of specific international regulations for evaluating the environmental impact of nanoparticles in marine environments, which complicates risk assessment and management.Given these concerns, it is crucial to develop eco-friendly nanomaterials and implement proper risk assessment strategies before using nanoparticles for marine applications such as environmental remediation.

"Although cyanobacteria can pose an environmental hazard, the researchers describe them as 'tiny carbon superheroes'. Through the process of photosynthesis, they play an important role in capturing about 12 per cent of the world’s carbon dioxide each year."Plants not only produce oxygen, they can sequester carbon too. Responding to the climate crisis is going to take more than transitioning to clean energy and reducing our carbon output. Luckily, agriculture can play a critical role in this. I'm excited to see how this research can further contribute to doing just that. #AustralianNationalUniversity #UniversityOfNewcastle #CarbonSequestration #PlantScience

When it comes to soil carbon in pasture fed beef systems, perspective is everything as Eric Barker points out in this excellent opinion piece 'Scientists carbon criticisms need to be put into perspective' published recently in Beef Central.Eric makes two important points.Firstly that there are members of the scientific community who are optimistic about the potential to manage pasture fed beef systems in such a way that increases the amount of carbon that gets stored in soils.In other words, the science is not all bad news.In fact, Australia is well served by the 2021 Soil Carbon Method which uses sound soil sampling practices, scientifically conservative calculations and regulatory grade monitoring, reporting and verification that is proven through reasonable assurance audits.And secondly, science is an important part of the overall policy discussion on soil carbon, but not the only part.Science is not the ultimate arbiter for incentive based programs to deliver necessary changes to our overall economy.Especially where many of the articles appearing in the peer reviewed literature are setting out to prove what can't be done in building soil carbon, as opposed to examining opportunities to grow healthier soils that remove large amounts of carbon from the atmosphere.As a carbon project aggregator I have had many labels that align with Eric's characterisation of the soil carbon market, including some with much more impolite language.In spite of this scepticism, next year marks the 10 year anniversary of the first soil carbon project to be registered in Australia.While things may have taken longer than originally anticipated, my prediction is that the 1,000th soil carbon project will be registered before this anniversary milestone.As more and more projects start issuing credits, I can easily see a future where the applied science breakthroughs driven from such widespread participation will accelerate the number of projects registered under the ACCU scheme by a factor of ten, and achieve this level of uptake in half the time in took to get the first 1,000 projects registered.In that world, the frontier question for the soil science community will not be whether Australian soils can sequester carbon, but rather how much carbon is too much soil carbon.
