BlueGreen’s groundbreaking, first-in-the-world carbon removal via harmful algal bloom remediation project was featured on KSL NewsRadio. Jan Wijbrand Spin explains #BlueGreen’s toxic algae carbon removal solution for Mantua Reservoir, Lake Guard Oxy, “So, what we’re basically using is a hydrogen peroxide-based solution, which creates oxidative stress on the colony. What we’ll do is transmit a signal - it’s often called ‘program cell death’ - which causes the colony to collapse.” The sequestered carbon is then buried in the sediment. The floating delivery method is key! Check out the full piece! https://lnkd.in/evB6PYd6 #WeMakeWaterSafe #WaterQuality #cyanobacteria #FeelGoodFriday

Engineered landfill cover soils (LCS) offer a promising approach for mitigating methane (CH4) emissions from landfills. This study explored how manipulating the microbial communities within LCS, specifically methanotrophs (MOB), can optimize CH4 biofiltration efficiency. https://lnkd.in/gB7Ktgmt #Biochar #landfill #landfillgas #soil #methane #biofiltration #methanotroph #microbialdiversity

Activity of aerobic methane-oxidizing bacteria (MOB) in anoxic lake waters: A new study in Nature Portfolio Communications by Sina Schorn, Sten Littmann, Jana Milucka and colleagues from our Greenhouses Gases Group demonstrates the persistent activity of aerobic methane-oxidizing bacteria (MOB) under anoxic conditions. The data show that some #methane-oxidizing #bacteria (#MOB) possess specific adaptations to #anoxic conditions, allowing them to maintain their activity even in the absence of oxygen. This finding provides an explanation for the ecological success of these bacteria in anoxic habitats. Furthermore the methane sink capacity of anoxic lake basins may be underestimated by not accounting for the anaerobic MOB activity. Methane is a potent #greenhouse gas, responsible for about one-third of the global temperature increase we are experiencing today. Methane oxidation by microorganisms is the main biological sink for methane, making their activity crucial for controlling methane #emissions into the atmosphere and thus regulating the global climate. Given the current and predicted expansion of anoxic events in temperate lakes, the importance of #methanotrophy in methane removal within lacustrine systems can be expected to intensify. Our results now suggest that MOB will make a significant contribution to greenhouse gas mitigation and carbon storage in future scenarios. https://lnkd.in/gnNa9KQc https://lnkd.in/gERN3mFj

Chopin et al.: "Deep-ocean seaweed dumping for carbon sequestration: Questionable, risky, and not the best use of valuable biomass Deep-ocean seaweed dumping is not an ecological, economical, or ethical answer to climate-change mitigation via carbon “sequestration.” Without sound science and sufficient knowledge on impacts to these fragile ecosystems, it distracts from more rational and effective blue-carbon interventions. We call for a moratorium on sinking seaweeds to deep-ocean ecosystems until its efficacy is established, and there is robust, evidence-based assessment of its environmental, economic, and societal sustainability." #mCDR #seaweed https://lnkd.in/e3FNdr4H

New research of a strain of Parachlorella kessleri with high productivity of electricity generation. Previously uncharacterized strain of the green alga P. kessleri - MACC-38, was found to produce a significantly higher electric current density than other. https://lnkd.in/gnNkf3-b #microalgae #chlorella #sustainability #zeroemission #carbonneutrality #carboncapture #environmentprotection #bioreactors #oxygen

A recent study introduced a magnetic #graphene-loaded #biochar gel (FeBG) for #soilremediation, significantly reducing arsenic and antimony bioavailability while improving nutrient availability and enzyme activities. This novel approach promises enhanced soil quality, highlighting the potential of integrating advanced materials for environmental restoration and sustainable agricultural ecosystems. https://lnkd.in/gPepdzpX

Managing phosphorus is one of the keys to winning the battle against algae blooms. It requires a multifaceted approach that begins with comprehensive monitoring of phosphorus levels. #WaterQuality #AlgaeBlooms #Phosphorus #PhosphateMonitoring #Environment

We keep working on innovative projects and research toward sustainable desalination development. Recently, we have published a paper in the prestigious journal Chemosphere, evaluating one of the main concerns regarding the potential impact of brine discharges. Is the brine from a reverse osmosis desalination plant more environmentally harmful than seawater with the same concentration of salts? See more details in the publication of Claudio Sáez Avaria.
