cadmium leaching from solar panels

“Either it becomes economical or it gets mandated. “If waste issues are not preemptively addressed,” warns Mulvaney, “the industry risks repeating the disastrous environmental mistakes of the electronics industry.”. 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. 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. IRENA projected that this amount could reach 78 million metric tonnes by 2050. 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. AU - Ramos-Ruiz, Adriana. The DTSC described building a database where solar panels and their toxicity could be tracked by their model numbers, but it’s not clear DTSC will do this. “Leaching potential test results show that such panels have a leaching potential of approximately 4 grams of lead per kilowatt installed, compared to approximately 23 grams of cadmium per kilowatt installed for CdTe panels. The International Renewable Energy Agency (IRENA) in 2016 estimated there was about 250,000 metric tonnes of solar panel waste in the world at the end of that year. So get over it and stop being a wannabe childish bully. Some compounds containing cadmium are thought to be carcinogenic. All the phoneys that came before were happy to provide you with the tools with which you could pretend to understand what you actually don’t understand. You are not a skeptic. James McGinn: 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. NO, none of you have, without those carefully made and verified measurements giving evidence that your theory is correct, and can be useful in predicting with good accuracy what the weather and climate will do in the future it is not that worthy. Principia Scientific International (PSI) is a not-for-profit community interest association. The editorial board of the Wall Street Journal? Photovoltaic panels never produce a fraction of their investment energy. Cadmium telluride, while considered less dangerous in relation to acute exposure,  is toxic if ingested, improperly handled or the dust inhaled. “I’ve been involved with millions of solar panels going into the field, and now they’re getting old.”. 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. Wise solar industry leaders can learn from the past and be proactive in seeking stricter regulation in accordance with growing scientific evidence that solar panels pose a risk of toxic chemical contamination. 2013, DOI: 10.1021/es402969c ). Several leaching technologies were assessed and the extraction of CdTe from samples of PV modules was optimized for maximum efficiency and minimum cost. Time Magazine “Hero of the Environment.”.
