Ferro-Alloy Resources Ltd (LSE:FAR) chief executive Nick Bridgen talked with Proactive's Stephen Gunnion about the latest developments at its Balasausqandiq project in Kazakhstan. The company is focused on vanadium and a carbon black substitute, both of which are expected to be highly competitive due to their low-cost production and environmental benefits. Bridgen discussed the ongoing feasibility study, which is nearing completion and is expected in the first half of 2025. He highlighted the importance of a recent non-binding offtake agreement with LL Resources for vanadium pentoxide, providing a degree of commercial security as the project advances. Regarding the carbon black substitute, he emphasised that it is a co-product rather than a byproduct, with revenue potential comparable to vanadium. “We've had a marketing study that tells us that it should sell for over $500 a ton. The market is huge,” Bridgen noted. As 2025 progresses, key milestones include the completion of the feasibility study and further commercial agreements for carbon black. Bridgen underscored the environmental benefits of Ferro-Alloy's production process, which emits significantly less CO2 compared to traditional methods.

This little-known pollutant is making us sick and driving the climate crisis. It commonly comes from burning coal, diesel or wood and has a habit of getting stuck in people's lungs as well as causing glaciers to melt. In Nepal, home to some of the world's most beautiful glaciers, we meet journalist Tulsi Rauniyar, who tells us all about the impact black carbon is having on women and children. She meets Tenzing Chogyal Sherpa, a glacier expert who maps the ice losses in the Himalayas. Zerin Osho from the Institute for Governance & Sustainable Development helps us understand why black carbon is so important - but often forgotten - in the fight against climate change, and how we can change that.

Comment une tempête de sable du Sahara génère un brouillard d'infox

Une partie de l'Europe va être de nouveau confrontée ce week-end au passage d'un nuage de poussière venant du Sahara. Il va se répandre dans le Sud de l'Espagne puis en France. Ces phénomènes sont naturels, mais il n'en faut pas plus pour alimenter des théories complotistes sur les réseaux sociaux, laissant penser que ces nuages sont créés de toutes pièces et sont constitués de produits chimiques destinés à empoisonner la population. Des thèses battues en brèche par les scientifiques. En Afrique saharienne, au Sahel et au Maghreb, les tempêtes de poussières sont bien connues des populations, mais quand le sable du Sahara arrive en Europe ou en Amérique, des thèses farfelues refont surface sur les réseaux sociaux. Lors du passage sur l'Europe d'un premier nuage, fin mars, on a pu lire sur X  (anciennement Twitter) des commentaires venant de la famille complotiste des adeptes de la théorie des « ChemTrails », selon laquelle des nuages toxiques sont secrètement fabriqués par le gouvernement américain pour provoquer des famines ou masquer le réchauffement climatique. Un narratif apparu dès les années 60, une théorie fumeuse reprise et adaptée au fil du temps.Phénomènes naturelsCes théories relayées par certains comptes sont totalement fausses : ces   tempêtes de sable sont des phénomènes naturels, comme l'explique Vincent Guidard, chercheur à Météo-France : « Tout commence sur des espaces de désert, en l'occurrence le Sahara. Quand les conditions météos sont réunies, le vent peut soulever le sable, qui retombe sur le sol et se fracture en plus petits morceaux, ensuite emportés par le flux jusqu'à 3, 5, 7 kilomètres d'altitude dans l'atmosphère. À cette altitude, les poussières sont transportées à travers l'Atlantique, ou vers l'Europe, en fonction de la situation météo (…)  On est dans la saison ou ces épisodes de poussières désertiques peuvent arriver sur l'Europe, et ce sont donc des choses qui arrivent régulièrement tous les ans, mais pas toujours avec le même nombre d'épisodes, et pas toujours avec la même intensité ».La parole des scientifiques, pas plus que celle des défenseurs de l'environnement, ne semble convaincre les sympathisants de ces théories du complot. Certains adeptes vont plus loin, en se basant sur des graphiques truqués ou documents sortis de leur contexte, afin d'affirmer que ces nuages contiennent des composés chimiques dangereux pulvérisés intentionnellement.Sphère complotisteSur les réseaux sociaux, un long article refait surface régulièrement. Un contenu en ligne, datant de 2022, publié sur le site internet tchèque Aeronet (AENews) qui n'est autre qu'un vecteur de la propagande russe considéré depuis longtemps par les autorités de Prague comme un site de désinformation. L'article a été reproduit le 2 avril et vu plus de 300 000 fois sur un seul compte X. Il est calqué mot pour mot sur la théorie complotiste des « Chem-Trail » assurant que du nickel, du baryum, et de l'aluminium et d'autres métaux sont retrouvés dans des proportions alarmantes dans les nuages empêchant, la lumière de passer et fragilisant les êtres vivants sur terre. Bien sûr, il n'en est rien.En France, l'Institut national de l'environnement industriel et des risques, qui analyse scientifiquement la composition de ces nuages de poussière n'évoque que des traces de substances, présentes à l'état naturel.Olivier Favez, chercheur à l'Ineris, explique : « Tout dépend du lieu, et de la saison, les particules sont un mélange très complexe avec une grande diversité de sources et des mécanismes de formation ou de transformation dans l'atmosphère. Quand on parle de particules fines – celles qu'il faut surveiller dans le cadre de veille sanitaire – on parle de PM10 ou PM2.5 donc des particules qui ont un diamètre inférieur à 10 ou 2,5 micromètres.  Un micromètre, c'est un millième de millimètre. Évidement, tout cela n'est pas visible à l'œil nu (…) La coloration rouge orangé du ciel, vient des oxydes de fer présents dans les poussières. Ils absorbent la lumière dans une certaine longueur d'onde, cela explique cette couleur particulière ».  Le scientifique de l'Ineris, que nous avons consulté, poursuit : « Dans les nuages de poussières, on va retrouver essentiellement des espèces carbonées émises par les activités humaines, issues de la combustion par exemple, (carbone suie / Black Carbon) (…) on va retrouver des sels, comme le nitrate d'ammonium, le plus souvent au printemps (…)  Enfin, on va retrouver dans une fraction un peu plus grossière des particules naturelles comme des sels marins (sodium-chlore) et puis des poussières minérales qui proviennent de l'érosion des sols. Si on s'intéresse essentiellement aux poussières sahariennes, nous allons retrouver du quartz, (silice) des aluminosilicates, donc avec de l'aluminium, et puis de la calcique, donc du calcium, du magnésium et des carbonates ». Radioactivité naturelleConcernant la présence d'éléments radioactifs — souvent brandie par les complotistes pour susciter la peur – il ajoute :  « C'est vrai qu'on va trouver ce genre de substances en concentrations dites traces ».   En chimie analytique, une trace désigne un produit présent en très faible quantité, donc très loin des prétendus dépassements de normes monumentaux que l'on retrouve systématiquement sur les sites complotistes. Olivier Favez précise : « Ce sont des substances naturelles, donc dans les particules de sable, on va retrouver la même chose que ce qu'il y avait dans la roche initiale au Sahara. Par exemple, si c'était un granite – comme on peut retrouver en Bretagne qui présente un sol radioactif naturel -, on va aussi retrouver ces éléments dans ces petites particules, mais je le répète, il s'agit d'éléments d'origine naturelle ».Dans la majorité des cas d'infox, visant des phénomènes naturels, explicables, et étudiés, on se retrouve confrontés à des déformations de données scientifiques, et à la production d'analyses trompeuses afin de contribuer à la création d'un climat anxiogène et d'alimenter des théories conspirationnistes. Le passage du nuage de sable du Sahara en est un exemple.Cet épisode météo est l'occasion de rappeler que la France est dotée d'une réglementation précise sur la surveillance de la qualité de l'air, puisqu'il existe des effets sanitaires avérés des polluants atmosphériques sur les personnes les plus fragiles. Un travail de prévention des risques conduit par la communauté scientifique au profit de la santé publique.

Ponette-Gonzalez's work focuses primarily on urban ecology.  She studies forests and trees and how they interact with the atmosphere and urban environments. She's done a lot of cutting edge research on things like urban ecology, urban black carbon, and what happens to smoke and dust. By studying how we humans impact our urban ecosystems, which in turn impacts the climate, she hopes to better understand what the future could look like, and where climate solutions may exist in urban environments. https://wilkescenter.utah.edu/podcast/16-urban-plants-black-carbon/

This afternoon The Two Mikes spoke with Den Black, a graduate engineer with GM, many years and a voice of common sense. Mr. Black said that there is no more science in the idea of man-made climate change than there was in the pandemic fraud, both are science free. Carbon Dioxide is one of the keys to life on this planet and to describe it as a pollutant amounts to a complete and deadly lie. Carbon Dioxide enables life on earth and in the oceans, and the more Carbon Dioxide there is in the air, the better all things grow, which assures many fewer people starve. Large amounts of extra Carbon Dioxide also are often piped into greenhouses growing vegetables or flowers and help produce far larger crops. Mr. Black said, rather wryly, that most of the true greenhouse gases in the atmosphere are in condensed vapor, more commonly known as clouds. He also said that people should recall that atmospheric changes occur as do geological changes; that is, in periods of times measured in tens or hundreds of thousand years. Automobile engines have been around for c.130 years and so could not possibly have changed much of anything in the globe's atmosphere in that miniscule sample period. He also asked that we keep in mind that Niagara Falls was once seven miles further up the Niagara River toward Lake Ontario than it is today. It took 70,000 years for the falls to retreat to its present location. It may yet retreat further down the Niagara River and meet Lake Erie but not for several hundred thousand years.

Black carbon, or soot, is part of fine particulate air pollution (PM2.5) and contributes to climate change. Black carbon is formed by the incomplete combustion of fossil fuels, wood and other fuels. Complete combustion would turn all carbon in the fuel into carbon dioxide (CO2), but combustion is never complete and CO2, carbon monoxide, volatile organic compounds, and organic carbon and black carbon particles are all formed in the process. The complex mixture of particulate matter resulting from incomplete combustion is often referred to as soot. Black carbon is a short-lived climate pollutant with a lifetime of only days to weeks after release in the atmosphere. During this short period of time, black carbon can have significant direct and indirect impacts on the climate, the cryosphere (snow and ice), agriculture and human health. Several studies have demonstrated that measures to prevent black carbon emissions can reduce near-term warming of the climate, increase crop yields and prevent premature deaths. --- Send in a voice message: https://anchor.fm/rahul182/message Support this podcast: https://anchor.fm/rahul182/support

Every year, over one billion tyres are manufactured worldwide, and equal number of tyres are permanently removed from vehicles, becoming waste. Although modern tyres are fundamentally rubber products, they are a complex mix of natural and synthetic rubbers. This complexity has led to stockpiling, dumping and diversion to landfill. This has exposed communities to environmental and health risks and has squandered valuable resources locked up in tyre dumps. Stockpiled tyres are at risk of fire and toxic smoke; other risks include the stagnant water in tyres that provides breeding grounds for mosquitoes and leaching of toxic substances into soils. India has been recycling and reusing waste tyres for four decades, although it is estimated that 60% are disposed of through illegal dumping. Carbon Black is an important ingredient to make tyres durable today. However its production is far from being sustainable. Even though carbon black is something you may not see every day you'll be surprised to know how it improves lives throughout the world by adding strength durability and enhanced performance to products we all use such as automobile tires, plastics like those used in your mobile phone or the dashboard of your car; it is used in cosmetics, ink toners for printers and copiers, paint and coatings and the ink that you read in your daily newspaper. Isn't it amazing how a mere powder is a common factor in all of our lives! If this material is so useful today, then just imagine how important it is to consider the sustainability aspect in this business operation?

Climate change from black carbon depends on altitude Scientists have known for decades that black carbon aerosols add to global warming. These airborne particles made of sooty carbon are believed to be among the largest man-made contributors to global warming because they absorb solar radiation and heat the atmosphere. New research from Carnegie’s Long Cao and Ken Caldeira, with colleagues, quantifies how black carbon’s impact on climate depends on its altitude in the atmosphere.

Contribution of Black Carbon and Atmospheric Brown Clouds to Climate Warming: Impacts and Opportunities Black carbon (BC) in soot is the dominant absorber of visible solar radiation in the atmosphere. Anthropogenic sources of black carbon, although distributed globally, are most concentrated in the tropics where solar irradiance is highest. Black carbon is often transported over long distances, mixing with other aerosols along the way. The aerosol mix can form transcontinental plumes of atmospheric brown clouds (ABCs), with vertical extents of 1.8 to 3.1 miles. Because of the combination of high absorption, a regional distribution roughly aligned with solar irradiance, and the capacity to form widespread atmospheric brown clouds in a mixture with other aerosols, emissions of black carbon are the second strongest contribution to current global warming, after carbon dioxide emissions. In the Himalayan region, solar heating from black carbon at high elevations may be just as important as carbon dioxide (CO2) in the melting of snowpacks and glaciers. The interception of solar radiation by atmospheric brown clouds leads to dimming at the Earth’s surface with important implications for the hydrological cycle, and the deposition of black carbon darkens snow and ice surfaces, which can contribute to melting, in particular of Arctic sea ice. Presently, populations on the order of 3 billion people are living under the influence of regional ABC hotspots. Black carbon (BC) is an important part of the combustion product commonly referred to as soot. BC in indoor environments is largely due to cooking with biofuels such as wood, dung and crop residue. Outdoors, it is due to fossil fuel combustion (diesel and coal), open biomass burning (associated with deforestation and crop residue burning), and cooking with biofuels. Soot aerosols absorb and scatter solar radiation. BC refers to the absorbing components of soot. Dust, which also absorbs solar radiation, is not included in the definition of BC. Globally, the annual emissions of BC are (for the year 1996) roughly 8.8 tons per year, with about 20% from biofuels, 40% from fossil fuels and 40% from open biomass burning. The uncertainty in the published estimates for BC emissions is a factor of two to five on regional scales and at least ±50% on global scales. High BC emissions occur in both the northern and the Southern Hemisphere, resulting largely from fossil fuel combustion and open burning, respectively. Atmospheric brown clouds are composed of numerous submicrometer aerosols, including BC, but also sulphates, nitrates, fly ash and others. BC is also internally mixed with other aerosol species such as sulphates, nitrates, organics, dust and sea salt. BC is removed from the atmosphere by rain and snowfall. Removal by precipitation, as well as direct deposition to the surface, limits the atmospheric lifetime of BC to about one (±1) week. Causal Link between Carbon Dioxide and Air Pollution Mortality Recent research suggests that carbon dioxide, through its increase in temperatures and water vapor, increases U.S. air pollution deaths. This effect is greatest in locations where air pollution is already high. The causes of the increased death rate are increased respiratory illness, cardiovascular diseases, and complications from asthma due to increases in ozone and particulate matter. Ozone increases with more carbon dioxide because, in urban areas, higher temperatures and water vapor independently increase ozone through enhanced chemical reactions. These effects are not so important in rural areas. However, in rural areas, higher temperatures increase organic gas emissions from vegetation, increasing ozone slightly. Particles increase with more carbon dioxide because carbon dioxide increases air temperatures more than ground temperatures, reducing vertical and horizontal dispersion of pollutants.
