cadmium leaching from solar panels

Lessons From A Chicken Wire Stack On Moon, Global Cooling: Beware the Snowman Cometh. The information below comes from Wikipedia: the final sentence puts the two in context… All you show there is your hypothesis replacing others, and it may have very much merit but without careful measurement and real scientific justification you have nothing. “The theory behind the regulations is to make [disposal] less burdensome,” explained Rick Brausch of DTSC. Is Sustainable Energy Even Possible Globally? Leaching of cadmium and tellurium from cadmium telluride (CdTe) thin-film solar panels under simulated landfill conditions. Research shows that “leaching of trace metals from modules is unlikely to present a significant risk due to the sealed nature of the installed cells.” Some solar modules use cadmium telluride (CdTe). According to a report by the World Health Organization in 2008, coal particulates pollution are estimated to shorten approximately 1,000,000 lives annually worldwide. | ACN: 632 317 545 | ABN: 41 632 317 545, SOLAR HOTLINE: 1800-EMATTERS (1800 362 883), Tasmania’s New Solar Incentive For Business, Home Solar Power Systems Boost House Value. Perhaps the biggest problem with solar panel waste is that there is so much of it, and that’s not going to change any time soon, for a basic physical reason: sunlight is dilute and diffuse and thus require large collectors to capture and convert the sun’s rays into electricity. Like all the rest of the pretenders that populate PSI, you only started caring when you saw that your political opponents were getting away with something. Till you can answer those simple question then you are as lost as the rest of us. AU - Wilkening, Jean V. AU - Field, James A. James McGinn: In the meantime you might as well start getting used to the fact that science involves work. From your link I see lots of negativity against current thinking — all well and fine but where is your science? My writings have appeared in The New York Times, Washington Post and Wall Street Journal, Scientific American, Nature Energy,…, Michael Shellenberger, President, Environmental Progress. The Two Bottles Experiment Explained, Older PROM papers are now under the Publications menu, “The reality is that there is a problem now, and it’s only going to get larger, expanding as rapidly as the PV industry expanded 10 years ago.”, “Contrary to previous assumptions, pollutants such as lead or carcinogenic cadmium can be almost completely washed out of the fragments of solar modules over a period of several months, for example by rainwater.”. Those large surface areas, in turn, require an order of magnitude more in materials — whether today’s toxic combination of glass, heavy metals, and rare earth elements, or some new material in the future — than other energy sources. ... First Solar has meanwhile been steadily reducing the amount of cadmium used in its solar cells. Currently, citizens have the right to file lawsuits against government agencies and corporations to force them to abide by various environmental laws, including ones that protect the public from toxic waste. California’s Department of Toxic Substances Control (DTSC), which is implementing the new regulations, held a meeting last August with solar and waste industry representatives to discuss how to deal with the issue of solar waste. Seth A. Robinson *a; George A. Meindl b a Department of Biology, University of Florida, Gainesville, FL, USA. Studies have shown the heavy metals in solar panels — namely lead and cadmium — can leach out of the cells and get into groundwater, as well as affect plants. Principia Scientific International (PSI) is a not-for-profit community interest association. “Any modules that were broken into small bits of glass had to be swept from the ground,” Mulvaney explained, “so lots of rocks and dirt got mixed in that would not work in recycling plants that are designed to take modules. The result of such bankruptcies is that the cost of managing or recycling PV waste will be born by the public. What propagandist rubbish. Dr Dumbass as you aptly put it is just a propagandist for Greenpeace, the nontaxable burden on society. Field Reyes Sierra-Alvarez Additionally, he said cadmium is considered 10 times more hazardous than lead. Cadmium is a heavy metal and extremely dangerous. Silicon is the same element in sand, and is non-toxic. Toshiba Environmental Solutions told Nikkei Asian Review last year that. Third, the United Nations Environment Programme’s Global Partnership for Waste Management, as part of its International Environmental Partnership Center,  should more strictly monitor e-waste shipments and encourage nations importing used solar panels into secondary markets to impose a fee to cover the cost of recycling or long-term management. In relation to solar panels, the CdTe is safe while encapsulated in the module, but if the panel is damaged and exposed to … I’m not running a hand holding service. PRINCIPIA SCIENTIFIC INTERNATIONAL is legally registered in the UK as a company incorporated for charitable purposes. PY - 2017/8/15. IRENA projected that this amount could reach 78 million metric tonnes by 2050. But it is notable that some new forms of electronic waste, namely smartphones like the iPhone, have in many cases replaced things like stereo systems, GPS devices, and alarm clocks and thus reduced their contribution to the e-waste stream. The attitude of some solar recyclers in China appears to feed this concern. With solar panels, added to the toxicity of manufacture, the lack of recyclability, relatively short lifetime, huge environmental and geographical foodprint, huge infrastructure, huge maintenance, and unreliability (the sun sets or it is cloudy, we can add fragility and exposure to the elements, which causes damage and aging. As the United Nation Environment Program notes, “loopholes in the current Waste Electrical and Electronic Equipment (WEEE) Directives allow the export of e-waste from developed to developing countries (70{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of the collected WEEE ends up in unreported and largely unknown destinations).”. A 2004 study commissioned by environmental groups, but contested by the US EPA, concluded that coal burning costs 24,000 lives a year in the United States. https ://, “coal fired per stations, which also produce large amounts of CO2, driving hazardous climate change?”. Cadmium dust is even more toxic, leading to respiratory, liver and kidney problems that can be fatal. And CO2 cannot acidify the oceans, and marine life and plant life all love more CO2. https ://, Accounting For Lorenz’s Missing Lubrication in the Atmosphere The main finding promoted by IRENA’s in its 2016 report was that, “If fully injected back into the economy, the value of the recovered material [from used solar panels] could exceed USD 15 billion by 2050.”, But IRENA’s study did not compare the value of recovered material to the cost of new materials and admitted that “Recent studies agree that PV material availability is not a major concern in the near term, but critical materials might impose limitations in the long term.”, They might, but today recycling costs more than the economic value of the materials recovered, which is why most solar panels end up in landfills. They are really only good for the end user who is isolated from the grid or wants to use less power from the grid. “But I’ve heard that it will have to be mandated because it won’t ever be economical.”. In an interview on CleanEnergyAuthority, Vice President of Technology for solar panel manufacturer REC, Trond Westgaard, said since cadmium telluride based panels are not officially considered a dangerous product, there is also a risk of them being mixed with other waste after being damaged or at the end of their serviceable life. You are a pretend skeptic. Cadmium is a major ingredient in one particular type of solar panel called cadmium telluride. They dare not sue, because to do…, Does this come as any surprise? Just How Accurate Are Weather And Climate Measurements? You are an ideologue. Such a recycling and waste management fund could help nations address their other e-waste problems while supporting the development of a new, high-tech industry in recycling solar panels. In the past, communities living near electronic waste dumps in Ghana, Nigeria, Vietnam, Bangladesh, Pakistan, and India have been primary e-waste destinations. When growth levels off then PV producers would face rapidly increasing recycling costs as a percentage of revenues. Perhaps you have the correct course, perhaps you are on the right road, without verified evidence you have nothing! PV array made of cadmium telluride (CdTe) solar panels Cadmium telluride (CdTe) photovoltaics describes a photovoltaic (PV) technology that is based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity. The first step is a fee on solar panel purchases to make sure that the cost of safely removing, recycling or storing solar panel waste is internalized into the price of solar panels and not externalized onto future taxpayers. A dilute aqueous solution of hydrogen peroxide and sulfuric acid was sufficient to completely leach … All of that waste creates a large quantity of material to track, which in turn requires requires coordinated, overlapping, and different responses at the international, national, state, and local levels. TomOMason: Although solar panels contain hazardous materials, such as lead and cadmium, they are sealed in enclosures or even sandwiched between plates of glass. What will be the wettest month in Californian next year, and which day will be the hottest in Berlin 2 years from now?
