Officials at the highest levels are discussing the possibility of caving in on controlling the coronavirus and instead letting it run rampant throughout the United States until we reach "herd immunity," the point where the virus effectively runs out of people to infect. More than 6,200 scientists, health professionals, and research organizations say this is inhumane and have signed a memorandum rejecting herd immunity as a legitimate strategy.
Herd Immunity’s Unacceptable Toll<p>Resumption of normal life in the United States under a herd immunity approach would result in an enormous death toll by all estimates. Former CDC director Tom Frieden <a href="https://www.washingtonpost.com/opinions/tom-frieden-herd-immunity-wrong-solution-coronavirus/2020/10/16/acb4ae8a-0fe6-11eb-8074-0e943a91bf08_story.html" target="_blank">estimates</a> that another 500,000 people would have to die to achieve 60 percent herd immunity. "And that's the best-case scenario," Frieden wrote in a <em>Washington Post</em> op-ed. "The number of deaths to get there could be twice as high."</p><p>Frieden said that is the best-case scenario because no one really knows if the <a href="https://www.mayoclinic.org/diseases-conditions/coronavirus/in-depth/herd-immunity-and-coronavirus/art-20486808" target="_blank">actual percentage needed</a> to see the virus peter out is to have it <a href="https://thehill.com/opinion/healthcare/521834-covid-19-vaccine-barriers-efficacy-availability-and-acceptability" target="_blank" rel="noopener noreferrer">infect</a> more like <a href="https://www.washingtonpost.com/health/2020/08/31/herd-immunity-covid-19/" target="_blank" rel="noopener noreferrer">65, 70,</a> or even <a href="https://www.vox.com/21451282/herd-immunity-explained-covid-19-pandemic" target="_blank" rel="noopener noreferrer">75 percent</a> of the population. Even if immunity could be miraculously achieved at 50 percent, an estimate <a href="https://www.nature.com/articles/s41577-020-00451-5" target="_blank" rel="noopener noreferrer">published</a> in <em>Nature Reviews Immunology</em> places the range of sacrifice somewhere between 500,000 and 2.1 million deaths.</p><p>That makes it little wonder that Anthony Fauci, the most respected scientist advising the Trump administration on the pandemic, called herd immunity for the coronavirus "total nonsense." Fauci is backed up by the likes of National Institutes of Health Director Francis Collins, who said herd immunity is a "dangerous" and "fringe" component of epidemiology. Ashish Jha, dean of the Brown University School of Health <a href="https://www.bostonglobe.com/2020/10/20/nation/scores-mass-scientists-doctors-sign-open-letter-against-herd-immunity-proposal/?outputType=amp" target="_blank" rel="noopener noreferrer">called</a> herd immunity "junk science."</p><p>The head of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, <a href="https://www.who.int/dg/speeches/detail/who-director-general-s-opening-remarks-at-the-media-briefing-on-covid-19---12-october-2020" target="_blank" rel="noopener noreferrer">said this month</a> that the only acceptable form of "herd immunity" is achieved through vaccination. "Herd immunity is achieved by protecting people from a virus, not by exposing them to it," the secretary general said. "Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic... Allowing a dangerous virus that we don't fully understand to run free is simply unethical. It's not an option."</p>
Herd Immunity Is the National De Facto Strategy<p>Somehow, none of that has culled herd immunity from being considered as a legitimate approach for fighting COVID-19. Rather, the Great Barrington Declaration has much in common with the Trump administration's approach to the coronavirus, which has led to more people dying from COVID-19 in the United States than in any other nation on Earth.</p><p>A de facto herd immunity approach is the only thing that can explain the push by governors of so many states to <a href="https://blog.ucsusa.org/derrick-jackson/the-push-to-relax-covid-19-protections-exposes-age-old-racial-wounds" target="_blank">reopen</a> bars, restaurants, beaches, bowling alleys, and gyms in states even as the virus has raged and case numbers have been increasing. It is the only thing that can explain the federal designation of meatpackers as essential workers and state demands that teachers go back into classrooms despite outbreaks and deaths related to those professions.</p><p>It also explains how so many of the nation's most respected scientific voices have been silenced. Despite the virus's current "uncontrolled spread" in 34 states and Puerto Rico, according to October 21 <a href="https://www.covidexitstrategy.org/" target="_blank" rel="noopener noreferrer">tracking</a> by CovidExistStrategy.org, the White House has pushed aside Fauci, Coronavirus Task Force Coordinator Deborah Birx, Surgeon General Jerome Adams, and Robert Redfield, the head of the Centers for Disease Prevention and Control.</p><p>In their place, the administration has handed the pandemic podium to <a href="https://www.washingtonpost.com/politics/trumps-den-of-dissent-inside-the-white-house-task-force-as-coronavirus-surges/2020/10/19/7ff8ee6a-0a6e-11eb-859b-f9c27abe638d_story.html?utm_campaign=wp_to_your_health&utm_medium=email&utm_source=newsletter&wpisrc=nl_tyh&wpmk=1&pwapi_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjb29raWVuYW1lIjoid3BfY3J0aWQiLCJpc3MiOiJDYXJ0YSIsImNvb2tpZXZhbHVlIjoiNWE1ZDQ3N2M5YmJjMGYyNmNiMTViMmI0IiwidGFnIjoiNWY4ZGZhZmQ5ZDJmZGEwZWZiNGViMzQyIiwidXJsIjoiaHR0cHM6Ly93d3cud2FzaGluZ3RvbnBvc3QuY29tL3BvbGl0aWNzL3RydW1wcy1kZW4tb2YtZGlzc2VudC1pbnNpZGUtdGhlLXdoaXRlLWhvdXNlLXRhc2stZm9yY2UtYXMtY29yb25hdmlydXMtc3VyZ2VzLzIwMjAvMTAvMTkvN2ZmOGVlNmEtMGE2ZS0xMWViLTg1OWItZjljMjdhYmU2MzhkX3N0b3J5Lmh0bWw_dXRtX2NhbXBhaWduPXdwX3RvX3lvdXJfaGVhbHRoJnV0bV9tZWRpdW09ZW1haWwmdXRtX3NvdXJjZT1uZXdzbGV0dGVyJndwaXNyYz1ubF90eWgmd3Btaz0xIn0.MyoXrwQD-PwWqdbb70_JfrI_fxHO0be_O_tpTTMXBgE" target="_blank" rel="noopener noreferrer">Scott Atlas</a>, a radiologist and conservative pundit with <a href="https://blog.ucsusa.org/derrick-jackson/public-wants-science-based-policies-for-covid-19" target="_blank" rel="noopener noreferrer">no background</a> in infectious disease science or epidemiology in measuring disease prevalence. Inhumanely ignoring the more than half of U.S. adults having a pre-existing condition that could compromise them for COVID-19, he blithely praises herd immunity, <a href="https://blog.ucsusa.org/derrick-jackson/public-wants-science-based-policies-for-covid-19" target="_blank" rel="noopener noreferrer">saying,</a> "We can allow a lot of people to get infected. Those who are not at risk to die or have a serious hospital-requiring illness, we should be fine with letting them get infected."</p><p>He <a href="https://thehill.com/homenews/administration/521688-birx-confronted-pence-about-atlas" target="_blank" rel="noopener noreferrer">pooh-poohs</a> expanded testing, saying, "you are destroying the workforce." Twitter recently took down one of Atlas's tweets for falsely claiming, "Masks work? NO" and then lying that the WHO says widespread mask use is "not supported." The first sentence of the WHO's <a href="https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/when-and-how-to-use-masks" target="_blank" rel="noopener noreferrer">webpage</a> on masks says, "Masks are a key measure to suppress the spread of COVID-19 and save lives."</p><p>Atlas denies that the White House has a "wide-open strategy of achieving herd immunity." But there's little doubt that the White House is wide open to the idea. Last week, Atlas <a href="https://www.foxnews.com/transcript/trump-adviser-calls-nbc-town-hall-brazen-display-of-media-duplicity" target="_blank" rel="noopener noreferrer">appeared</a> on Fox News <a href="https://www.wsj.com/articles/white-house-touts-document-calling-for-herd-immunity-approach-to-covid-19-crisis-11603051550" target="_blank" rel="noopener noreferrer">to say</a> the thrust of the Great Barrington Declaration "is exactly aligned with the president." That was seconded by a senior administration official who <a href="https://www.washingtonpost.com/health/covid-herd-immunity/2020/10/10/3910251c-0a60-11eb-859b-f9c27abe638d_story.html" target="_blank" rel="noopener noreferrer">told reporters</a> in a conference call that the Great Barrington Declaration "is endorsing what the president's policy has been for months."</p><p>The freezing out of scientists on the Coronavirus Task Force reached deep space levels this week (a metaphoric minus 455 degrees Fahrenheit), with multiple buckets of ice dumped on Fauci. Atlas diminished Fauci as "just one person" on the force, offering only a "limited approach." President Trump called Fauci a "disaster," <a href="https://www.washingtonpost.com/politics/trump-fauci-campaign-biden/2020/10/19/30b2fe58-1226-11eb-82af-864652063d61_story.html" target="_blank" rel="noopener noreferrer">claiming,</a> "People are tired of hearing Fauci and these idiots, all these idiots who got it wrong."</p>
Many Thousands of Lives Can Still Be Saved<p>Atlas's malpractice already merits his dismissal. He should be forced to step down because his disregard for science will surely lead to incalculable disaster if a herd immunity approach becomes official government policy. Calls for his ouster have already begun even from inside the task force. <a href="https://www.washingtonpost.com/politics/trumps-den-of-dissent-inside-the-white-house-task-force-as-coronavirus-surges/2020/10/19/7ff8ee6a-0a6e-11eb-859b-f9c27abe638d_story.html" target="_blank">According</a> to the <em>Washington Post</em>, Birx went to Vice President Mike Pence to suggest removing Atlas. All Pence reportedly did was ask Birx and Atlas to work out their problems on their own.</p><p>There is no time left for such discord within the task force and for discordant messages to come from the White House on how people should protect themselves from COVID-19. The thousands of scientists and public health professionals who signed the John Snow Memorandum say "it is critical to act decisively and urgently," to launch a "robust" response on the level of New Zealand, Vietnam, or Japan—all of which have shown success in containing the virus and keeping the numbers of cases and deaths relatively low.</p><p>The approach that has been proven effective starts with face coverings and social distancing and reducing the temptation we all will feel during the oncoming winter holidays to have extended family gatherings. Researchers from MIT and the Vancouver School of Economics <a href="https://www.medrxiv.org/content/10.1101/2020.05.27.20115139v6.full.pdf" target="_blank">estimate</a> in a working paper that, if the United States had established a national mask mandate in mid-March, between 19,000 and 47,000 lives could have been saved by the end of May. Now that the nation's death toll approaches a quarter million lives lost, and is <a href="https://covid19.healthdata.org/united-states-of-america?view=total-deaths&tab=trend" target="_blank" rel="noopener noreferrer">projected</a> to reach nearly 400,000 by February 1, according to the Institutes for Health Metrics and Evaluation at the University of Washington, the institute estimates we could avoid 74,000 new deaths with universal mask use.</p><p>Importantly, masks protect others, including the most vulnerable among us. This week, the <em>Washington Post</em> reported how coronavirus outbreaks among college students partying in unmasked packs in LaCrosse, Wisconsin was found to have <a href="https://www.washingtonpost.com/health/2020/10/21/la-crosse-wisconsin-covid-outbreak-nursing-home-deaths/?utm_campaign=wp_to_your_health&utm_medium=email&utm_source=newsletter&wpisrc=nl_tyh&wpmk=1&pwapi_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjb29raWVuYW1lIjoid3BfY3J0aWQiLCJpc3MiOiJDYXJ0YSIsImNvb2tpZXZhbHVlIjoiNWE1ZDQ3N2M5YmJjMGYyNmNiMTViMmI0IiwidGFnIjoiNWY5MWU3YjU5ZDJmZGEwZWZiNTE3OGNmIiwidXJsIjoiaHR0cHM6Ly93d3cud2FzaGluZ3RvbnBvc3QuY29tL2hlYWx0aC8yMDIwLzEwLzIxL2xhLWNyb3NzZS13aXNjb25zaW4tY292aWQtb3V0YnJlYWstbnVyc2luZy1ob21lLWRlYXRocy8_dXRtX2NhbXBhaWduPXdwX3RvX3lvdXJfaGVhbHRoJnV0bV9tZWRpdW09ZW1haWwmdXRtX3NvdXJjZT1uZXdzbGV0dGVyJndwaXNyYz1ubF90eWgmd3Btaz0xIn0.6Ep-AvkJkNqGTE08UsekVlNWR01vYzQe-qg5BPruSQM" target="_blank" rel="noopener noreferrer">led to 19 deaths so far of people over the age of 60</a>. Before that, the city had gone without a single pandemic death in its nursing homes.</p><p>That is on the heels of the wedding in Millinocket, Maine that resulted in an outbreak that <a href="https://bangordailynews.com/2020/09/19/news/eight-deaths-now-tied-to-millinocket-area-wedding-outbreak-including-seven-at-nursing-home/" target="_blank" rel="noopener noreferrer">killed eight elderly people</a>, none of whom attended the event, and the 500,000-person Sturgis, South Dakota motorcycle rally that is <a href="https://www.washingtonpost.com/health/2020/10/17/sturgis-rally-spread/" target="_blank" rel="noopener noreferrer">now tied</a> to the massive coronavirus outbreak in the Upper Midwest and Mountain States.

What if paint could cool off a building enough to not need air conditioning?

This way, heat doesn't get trapped within the atmosphere and contribute to global warming. A video about this project is available on <a href="https://www.youtube.com/watch?v=caFzYvYAUo4&feature=youtu.be" target="_blank">YouTube</a>.</p><p>"We're not moving heat from the surface to the atmosphere. We're just dumping it all out into the universe, which is an infinite heat sink," said Xiangyu Li, a postdoctoral researcher at the Massachusetts Institute of Technology who worked on this project as a Ph.D. student in Ruan's lab.</p><p>Earth's surface would actually get cooler with this technology if the paint were applied to a variety of surfaces including roads, rooftops and cars all over the world, the researchers said.</p>
An infrared camera image shows that white radiative cooling paint developed by Purdue University researchers (left, purple) can stay cooler in direct sunlight compared with commercial white paint.

These readings confirmed that our paint has a lower temperature than both its surroundings and the commercial counterpart," Ruan said.</p><p>Commercial "heat rejecting paints" currently on the market reflect only 80%-90% of sunlight and cannot achieve temperatures below their surroundings.

Plain Naturals is making waves in the CBD space with a new product line for retail customers looking for high potency CBD products at industry-low prices.

Plain Naturals offers a 5000mg CBD oil tincture in 30ml bottle for $99.99.<p>Consumers have gotten used to paying high prices for low amounts of cannabidiol. Plain Naturals is beginning to change that. There are myriad <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5569602/%23:~:text=Chronic%2520use%2520and%2520high%2520doses,be%2520well%2520tolerated%2520by%2520humans.&text=Nonetheless%252C%2520some%2520side%2520effects%2520have,vitro%2520or%2520in%2520animal%2520studies." target="_blank" rel="noopener noreferrer nofollow">studies</a> showing that low doses of CBD (less than 50mg per day) are ineffective for many users.

But the advantage of starting with a higher potency CBD oil is that it is much easier to use less to start with and increase over time than to buy very low dose CBD oil and ultimately end up buying more and more stronger products. To start at 50mg per dose of a 5000mg oil, you would simply use ⅓ dropper or about 10-12 drops.</p>

When university presidents were surveyed in spring of 2020 about what they felt were the most pressing concerns of COVID-19, college students going hungry didn't rank very high.
Why It Matters<p>This is not just a matter of growling stomachs. This is a straight-up education and health issue.</p><p>When students don't really know if they'll be able to get enough to eat, it can lead to a series of problems that make it harder to stay in school. For instance, it can affect <a href="https://doi.org/10.1177%2F1359105318783028" target="_blank">academic performance</a> and <a href="https://doi.org/10.1186/s12889-019-6943-6" target="_blank" rel="noopener noreferrer">sleep quality</a>. It can also lead to <a href="https://doi.org/10.1177/1359105318783028" target="_blank" rel="noopener noreferrer">poor mental and physical health</a> outcomes for college students.</p><p>Food insecurity can also result in disrupted eating patterns if there is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6627945/" target="_blank" rel="noopener noreferrer">not enough food or the variety</a> or <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-019-6943-6" target="_blank" rel="noopener noreferrer">quality of what someone eats</a> is low.</p>
Campus Food Pantries<p>Previous strategies by <a href="https://www.gao.gov/assets/700/696254.pdf" target="_blank">colleges and universities</a> to fight hunger in their student bodies have varied widely. They include campus food pantries, emergency cash assistance and nutrition education through noncredit classes or workshopse.</p><p>These strategies were put to the test during the spring 2020 semester, when nearly <a href="https://hope4college.com/wp-content/uploads/2020/06/Hopecenter_RealCollegeDuringthePandemic.pdf" target="_blank">three in five students</a> said they had trouble meeting their own basic needs during the pandemic.</p><p>College food pantries saw <a href="https://www.utrgv.edu/newsroom/2020/05/01-utrgv-student-food-pantry-seeing-recent-increase-in-demand-during-covid-19.htm" target="_blank" rel="noopener noreferrer">big increases</a> in demand. Others said they <a href="https://www.theprospectordaily.com/2020/09/22/uteps-food-pantry-is-running-out-of-food/" target="_blank" rel="noopener noreferrer">were getting less donated food</a>. This made it even harder to meet the rising food needs of students.</p><p>Campus food pantries largely rely on local or regional food banks, which have been dealing with <a href="https://www.indystar.com/story/news/local/2020/10/04/indiana-food-banks-call-more-food-stamps-meet-publics-need/3523683001/" target="_blank" rel="noopener noreferrer">greater demand</a> than they are able to meet during the pandemic.</p><p>The many students who are attending college remotely will, of course, have less access to campus resources like food pantries.</p>
Federal Help<p>Other potential ways to get more food are government programs like the <a href="https://www.fns.usda.gov/snap/recipient/eligibility" target="_blank">Supplemental Nutrition Assistance Program</a>, known as SNAP. Yet the majority of able-bodied students are not eligible. Long-standing restrictions, like the <a href="https://www.fns.usda.gov/snap/students" target="_blank">college SNAP rule</a>, prevent full-time students from receiving these benefits.</p><p>Such regulatory hurdles were created under the assumption that most students can rely on their parents to get enough to eat. However, college students have vastly different levels of financial support. Some students can rely on their parents for everything and others cannot rely on their parents for anything.</p><p>Decreased reliance on parental financial support is <a href="https://ir.library.louisville.edu/jsfa/vol47/iss3/5/" target="_blank">especially common</a> for first-generation students and students of color, who now make up <a href="https://1xfsu31b52d33idlp13twtos-wpengine.netdna-ssl.com/wp-content/uploads/2019/02/Race-and-Ethnicity-in-Higher-Education.pdf" target="_blank" rel="noopener noreferrer">45% of enrolled college students</a>.</p><p>Under normal circumstances, many college students might rely on part-time jobs to pay for their food.</p>
Short-Term Solutions<p>Universities and colleges can make it a priority to ensure students are aware of all available campus resources and services. They can also potentially help students apply for federal assistance benefits.</p><p>Campus food pantries are not a fully effective and efficacious solution for the scale of college food insecurity, but they can be a good interim solution to increase access to food for students.</p><p>Campuses without food pantries can start one, making use of resources the <a href="https://cufba.org/resources/" target="_blank">College and University Food Bank Alliance</a> provides. Schools with food pantries can try to get them to <a href="https://www.swipehunger.org/5campuspantry/" target="_blank" rel="noopener noreferrer">reach more students</a>.</p><p>Universities and colleges can also lean on one another for support. The <a href="http://wp.auburn.edu/endchildhungeral/alabama-campus-coalition-for-basic-needs/" target="_blank" rel="noopener noreferrer">Alabama Campus Coalition for Basic Needs</a> is a great example of this. It brings together 10 universities across the state of Alabama collectively working to address student food insecurity.</p>

Of all the plastic we've ever produced, only 9% has been recycled. So what happened to all that plastic you've put in the recycling bin over the years?
Triangle of Mistruths<p>The myth created around plastic recycling has been one of simplicity. We look for the familiar triangle arrows, then pop the waste in the recycling bin so it can be reused.</p><p>But the true purpose of those triangles has been misunderstood by the general public ever since their invention in the 1980s.</p><p>These triangles were actually created by the plastics industry and, according to a report provided to them in July 1993, <a href="https://www.npr.org/transcripts/912150085" target="_blank">were creating "unrealistic expectations"</a> about what could be recycled. But they decided to keep using the codes.</p><p>Which is why many people still believe that these triangular symbols (also known as a <a href="https://sustainablepackaging.org/101-resin-identification-codes/" target="_blank" rel="noopener noreferrer">resin identifier code</a> or RIC) means something is recyclable.</p><p>But according to the American Society for Testing and Materials International (ASTM) – which controls the RIC system – the numbered triangles "<a href="https://www.astm.org/Standards/D7611.htm" target="_blank" rel="noopener noreferrer">are not recycle codes</a>." In fact, they weren't created for the general public at all. They were made for the post-consumer plastic industry.</p><p>In other words, the symbols make it easier to sort the different types of plastics, some of which cannot be recycled – <a href="https://www.ecobin.com.au/understand-recycling-codes/" target="_blank" rel="noopener noreferrer">depending on the recycling facility</a>.</p><p>"Unfortunately, just placing your plastic into the recycling bin doesn't mean it will get recycled," says Lara Camilla Pinho. She is an architect and lecturer at the UWA School of Design who is researching novel uses of plastic waste.</p><p>"The recycling system is complicated and often dictated by market demand. Not all plastic is recyclable. We cannot recycle plastic bags or straws for example."</p>
Behind the Scenes<p>So, what makes recycling plastics so difficult?</p><p>"Essentially, there are two types of plastics – thermoplastics and thermosets. While thermoplastics can be re-melted and re-molded, thermosets contain cross-linked polymers that cannot be separated meaning they cannot be recycled," says Lara.</p><p>"Even thermoplastics have a limit to the amount of times we can recycle them, as each time they are recycled they downgrade in quality."</p><p>Even when plastics are recyclable, it is <a href="https://www.theguardian.com/environment/2019/oct/13/war-on-plastic-waste-faces-setback-as-cost-of-recycled-material-soars" target="_blank">often more costly</a> than simply making new plastics.</p>
Sugar, Seaweed and Mushrooms<p>If the conventional recycling system isn't working, what else can we do with all the plastic we've created?</p><p>Lara is looking for ways to add value to recycled plastics such as using it in the design and development of architectural products. She hopes to use these architectural products to help underserved communities that are disproportionately affected by plastic waste.</p><p>In addition to recycling, we also need to find ways to reduce our use of virgin petroleum-based plastics.</p><p>Bioplastic is one such product that has been getting a lot of hype over the last few years. And although they're better than petroleum-based plastics, bioplastics also come with their own <a href="https://phys.org/news/2017-12-truth-bioplastics.html" target="_blank">set of challenges</a>.</p><p>"There are already a lot of bio-based alternatives to plastic, such as bagasse – a byproduct of sugar cane processing," says Lara.</p><p><a href="https://blogs.scientificamerican.com/observations/the-mycelium-revolution-is-upon-us/" target="_blank" rel="noopener noreferrer">Mycelium</a>, a type of fungi we most often associate with mushrooms, are also providing an interesting plastic alternative.</p><p>"In the field of architecture, mycelium is starting to be used as an alternative to plastic insulation, but also as compostable packaging and bricks," says Lara.</p><p>"The bricks take around five days to make and are strong, durable, water resistant and compostable at the end of their use."</p><p><a href="https://www.arup.com/news-and-events/hyfi-reinvents-the-brick" target="_blank" rel="noopener noreferrer">Hy-Fi Tower</a>, created by <a href="http://www.thelivingnewyork.com/living_about.html" target="_blank" rel="noopener noreferrer">The Living</a>, is an example of a building made from these bricks.</p><p>And finally, there's seaweed.</p><p>"[Seaweed is] cheap and can reproduce itself quickly without fertilizers. In architecture, there is use for seaweed as an alternative to plastic insulation but also as cladding," says Lara.</p>
More Money, More Problems<p>While all these alternatives are great, the main cause of our plastic dilemma is not scientific or technological, but economic.</p><p>As long as it remains <a href="https://engineering.mit.edu/engage/ask-an-engineer/why-is-it-cheaper-to-make-new-plastic-bottles-than-to-recycle-old-ones/" target="_blank">cheaper to create new plastics</a> from fossil fuels rather than from bioplastics or from recycling, we're going to be stuck with plastic garbage islands floating in our oceans.</p><p>The true cost to our health and our environment has yet to be included in the equation. But once it is, maybe that is when the real shift will happen.</p>

As concern mounts over the impacts of climate change, many experts are calling for greater use of electricity as a substitute for fossil fuels. Powered by advancements in battery technology, the number of plug-in hybrid and electric vehicles on U.S. roads is increasing. And utilities are generating a growing share of their power from renewable fuels, supported by large-scale battery storage systems.

Hazardous Contents<p>Batteries pose more complex recycling and disposal challenges than metals, plastics and paper products because they contain many chemical components that are both toxic and difficult to separate.</p><p>Some types of widely used batteries – notably, lead-acid batteries in gasoline-powered cars – have relatively simple chemistries and designs that make them straightforward to recycle. The common nonrechargeable alkaline or water-based batteries that power devices like flashlights and smoke alarms can be disposed directly in landfills.</p><p>However, today's lithium-ion batteries are highly sophisticated and not designed for recyclability. They contain hazardous chemicals, such as toxic lithium salts and <a href="https://www.britannica.com/science/transition-metal" target="_blank">transition metals</a>, that can damage the environment and leach into water sources. Used lithium batteries also contain embedded electrochemical energy – a small amount of charge left over after they can no longer power devices – which can cause fires or explosions, or <a href="https://www.epw.senate.gov/public/_cache/files/e/5/e5530917-434d-451c-8a6b-c5cdfad1b5ec/EED12407A6BF7DE6C86A4B39C25CF6A4.greenberger-testimony-07.17.2019.pdf" target="_blank" rel="noopener noreferrer">harm people that handle them</a>.</p>

Safer and Simpler<p>While it will be challenging to bake recyclability into the existing manufacturing of conventional lithium-ion batteries, it is vital to develop sustainable practices for solid-state batteries, which are a next-generation technology expected to enter the market within this decade.</p><p>A solid-state battery replaces the flammable organic liquid electrolyte in lithium-ion batteries with a nonflammable inorganic solid electrolyte. This allows the battery to operate over a much wider temperature range and dramatically reduces the risk of fires or explosions. Our <a href="http://zhengchen.eng.ucsd.edu/" target="_blank">team of nanoengineers</a> is working to incorporate ease of recyclability into next-generation solid-state battery development before these batteries enter the market.</p><p>Conceptually, recycling-friendly batteries must be safe to handle and transport, simple to dismantle, cost-effective to manufacture and minimally harmful to the environment. After analyzing the options, we've chosen a combination of specific chemistries in next-generation all-solid-state batteries that <a href="https://doi.org/10.1557/mre.2020.25" target="_blank" rel="noopener noreferrer">meets these requirements</a>.</p><p>Our design strategy reduces the number of steps required to dismantle the battery, and avoids using combustion or harmful chemicals such as acids or toxic organic solvents. Instead, it employs only safe, low-cost materials such as alcohol and water-based recycling techniques. This approach is scalable and environmentally friendly. It dramatically simplifies conventional battery recycling processes and makes it safe to disassemble and handle the materials.</p>
Rules for Battery Recycling<p>Developing an easy-to-recycle battery is just one step. Many challenges associated with battery recycling stem from the complex logistics of handling them. Creating facilities, regulations and practices for collecting batteries is just as important as developing better recycling technologies. China, South Korea and the European Union are <a href="https://www.epw.senate.gov/public/_cache/files/d/c/dc43cdc9-ef56-4f8c-b442-d325aa8acf72/D775B276380B37ABF9A49BFD581DD1A5.sanders-testimony-07.17.2019.pdf" target="_blank">already developing battery recycling systems and mandates</a>.</p><p>One useful step would be for governments to require that batteries carry universal tags, similar to the internationally recognized standard labels used for plastics and metals recycling. These could help to educate consumers and waste collectors about how to handle different types of used batteries.</p><p>Markings could take the form of an electronic tag printed on battery labels with embedded information, such as chemistry type, age and manufacturer. Making this data readily available would facilitate automated sorting of large volumes of batteries at waste facilities.</p><p>It is also vital to improve international enforcement of recycling policies. Most battery waste is not generated where the batteries were originally produced, which makes it hard to hold manufacturers responsible for handling it.</p><p>Such an undertaking would require manufacturers and regulatory agencies to work together on newer recycling-friendly designs and better collection infrastructure. By confronting these challenges now, we believe it is possible to avoid or reduce the harmful effects of battery waste in the future.</p>
