    Claim questioned

    An article published on Jan. 8 in the American Journal of Public Health (AJPH) dismisses the claim that e-cigarettes are 95 percent safer than combustible cigarettes as a “factoid”—unreliable information repeated so often that it becomes accepted as fact.

    The 95 percent claim stems from a 2013 study rating the relative harm of 12 nicotine products using 14 criteria. The authors of the 2013 study concluded that electronic cigarettes were substantially less harmful than combustible cigarettes. Their claim was characterized in the popular media as e-cigarettes being “95 percent less risky” than tobacco cigarettes.

    Although the researchers of the original study acknowledged the shortcomings of their work—i.e., a lack of hard evidence for the harms of most products on most criteria—Public Health England and the Royal College of Physicians endorsed the claim, lending it credibility.

    The authors of the AJPH article point out that today’s vapor products are very different from those available in 2013. The devices are now more powerful, create more aerosol and expose users to more toxicants.

    The proliferation of e-liquids with nicotine salts, meanwhile, allow users to inhale significantly higher levels of nicotine. In addition, more research has emerged about the toxicants in e-cigarettes and their potential respiratory and cardiovascular effects, according to the AJPH article.

    “Even if the 2013 estimate was valid then it can no longer apply today,” the authors of the AJPH article wrote.

    “Public health practitioners, scientists and physicians should expose the fragile status of the 95 percent less risky claim by highlighting its unreliable provenance and lack of validity today,” they added.

  • Understanding Chemistry

    Understanding Chemistry

    Broughton Nicotine Services has launched an in-house service focused on enabling companies in the Electronic Nicotine Delivery Systems (ENDS) sector to fully understand the chemistry and safety of their products.

    The new extractables and leachables team will adopt scientific techniques to investigate any compounds present in an e-liquid or delivery device that could present a health risk to the end user.

    “Our extractables and leachables service will enable ENDS companies to work with one key partner throughout the regulatory process and demonstrate the potential impact of their products on public health,” said Leon Birch, head of scientific development at Broughton Nicotine Services.

    “It’s great to be part of a team dedicated to supporting companies in the ENDS sector, helping them to advance a smoke-free future.”

  • MRTP for General Snus: Small Step or Giant Leap?

    MRTP for General Snus: Small Step or Giant Leap?

    While a victory for tobacco harm reduction, the impact of the U.S. Food and Drug Administration’s recent nod to General snus should not be overstated.

    By George Gay

    A number of people have made the point, one way or another, that it is often unpalatable to find yourself in agreement with a majority opinion. And a few seconds’ thought will provide numerous examples of when and where this would have been true. Though, in some cases and for some people, the truth might have become obvious only in retrospect. Many of those examples, however, will also demonstrate that it can be uncomfortable, even dangerous, to challenge majority views.

    But even when there is no danger involved, most people don’t like to be the odd one out, as numerous experiments have shown. If you ask somebody to measure the length of a stick and then ask her to pick the length she measured from a multiple-choice answer, she will almost always come up with the right answer. But conduct the same experiment with the same person and six others primed to pick and declare out loud before she does one of the other answers, and the subject of the experiment is highly likely to fall in with the answer given by the others, no matter that the answer might not bear a close resemblance to the length of the stick. The thinking seems to be better wrong than different.

    I find this attitude difficult to accept, and so I find myself partly at odds with a development that many have found inspiring. In October, the U.S. Food and Drug Administration (FDA) announced that it had, for the first time, authorized the marketing of products through its modified-risk tobacco product (MRTP) pathway. The authorizations are for eight Swedish Match USA (SMUSA) snus smokeless tobacco products sold under the General brand name, the FDA said in a statement published on Oct. 22.

    At first glance, this seemed all very positive, but the more I read, the more it struck me that the press note and some of the commentary attached to it did not warrant the sound of triumph that emerged—the idea that what happened represented a major victory for the future of tobacco harm reduction. On close reading, while the announcement was to be welcomed as a tiny step in the right direction, it carried so much baggage that the step was unsteady.

    The “for the first time” phrase used in the first sentence of the press note presented an impressive front, but the reality is much different. The FDA’s first-time decision and announcement had taken more than five years—an unconscionable length of time given that traditional cigarettes continued throughout that period to take the lives of more than 400,000 smokers a year. And it wasn’t as if the latest application had been the first. Three years ago, the FDA, in effect, turned down three reasonable requests from SMUSA in relation to health warnings that were required to be applied to all smokeless products, including General snus, condemning the U.S. to another three years at 400,000 deaths a year.

    It would be absurd, of course, to say that 2 million people’s lives could have been saved over those five years if the MRTP had been granted in reasonable time, but the chances are that many lives would have been saved and that the momentum behind switching from combustibles to Swedish-style snus would by now have built a solid foundation.

    Nudge, nudge, wink, wink

    As it is, SMUSA has to start from now, and still has a mountain to climb in changing attitudes to its authorized products, in part because official information on the health implications of using snus has been misleading and because, even now, the October FDA announcement is nothing if not equivocal. And it couldn’t be otherwise simply because it is based on what is termed a “modified risk.” What is the woman in the street to make of a “modified risk”? Hey, they think they can save my right leg, but apparently my left arm might drop off.

    True, the FDA decision allows SMUSA to market the products in question by saying, “Using General snus instead of cigarettes puts you at a lower risk of mouth cancer, heart disease, lung cancer, stroke, emphysema and chronic bronchitis.” But, according to the press note, this is just a “claim.” And just to underline this, the third paragraph states, “While today’s decision permits the eight General brand snus smokeless tobacco products to be sold in the U.S. with a modified-risk claim, it does not mean these products are safe or ‘FDA approved.’ All tobacco products are potentially harmful and addictive, and those who do not use tobacco products should continue to refrain from their use. The modified-risk orders are product specific and limited to five years.”

    Again, what is the woman in the street to make of this? Nudge, nudge, wink, wink—don’t touch this stuff with a bargepole?

    And if you didn’t get that hint, perhaps you picked up the one in the previous paragraph: “In an effort to help prevent youth access and exposure, the agency has also placed stringent advertising and promotion restrictions on the products, including a requirement to restrict advertising to adults. In addition, the products’ packaging and advertising must also bear the warning statements required for all smokeless tobacco products.”

    And what are those warnings? This product can cause mouth cancer, and this product can cause gum disease and tooth loss. In other words, the FDA is hedging its bets. Yes, it seems to be saying, these General snus products are demonstrably different to others on the market and that is why the agency has issued an MRTP, but, on the other hand, they aren’t different and that is why they have to carry the same warnings as other smokeless products.

    And just in case you’re particularly dumb and still didn’t quite get the message, the same points that are laid out in the second paragraph are repeated in the fourth. The FDA has cloaked itself in so many layers of the cautionary principle that it is unable to move. After five years of examining what must be close to the most benign tobacco product ever to be devised, it was unable to issue an unqualified statement saying the consumption of these eight products is way less risky than smoking.

    Quoting acting FDA Commissioner Ned Sharpless, the FDA’s press note states, “Today’s action demonstrates the viability of the pathway for companies to market specific tobacco products as less harmful to consumers but only following a thorough scientific evaluation by the FDA. Our team of scientific experts examined these applications to ensure that the tobacco products meet the public health standards in the law.”

    Of course, this is true, up to a point, but it hides some other uncomfortable truths. Yes, it is the case that the recently issued MRTP has proved that, 10 years after the enactment of the Family Smoking Prevention and Tobacco Control Act, one company has found a way to convince the FDA to equivocate on the health implications of eight of its products. But that is an awfully long time and an awful lot of resources to not get very far. And even that limited achievement is not set in stone. As Sharpless was quoted in the press note, “Should any information lead us to determine that the marketing of these products as posing less risk no longer benefits the health of the population as a whole, the agency would consider withdrawing this authorization.” It is worth noting that when Sharpless talks of “any information,” he is including information undoubtedly already being prepared by the legions of quit-or-die advocates circling the courts.

    A viable pathway for who?

    You have to ask yourself, what does it mean for Sharpless to say that this is a viable pathway for “companies to market specific tobacco products as less harmful to consumers”? Let’s be aware of the import of this. He cannot possibly be talking about any old company; he has to be talking about companies with big pockets. No ordinary company could afford to allocate to such an uncertain undertaking five years’ worth of the sorts of resources necessary to put together and present the results of the detailed research demanded by the FDA.

    The investment does not stop with the granting of the MRTP. The press note points out, “With the authorization of these products, the company is required to conduct post-market studies to determine the impact of modified-risk tobacco product orders on consumer perception, behavior and health …. The company is required to report regularly to the FDA with information regarding the products on the market, including, but not limited to, ongoing and completed consumer research studies, advertising, marketing plans, sales data, information on current and new users, manufacturing changes and adverse experiences.” It is to be hoped that quit-or-die advocates will be held to the same standards.

    Later, the note adds, “To continuously market these same products with the same modified-risk information beyond the five-year limit would require the company to submit a request for renewal and receive renewal authorization from the FDA before the current orders expire.” Of course, it should add that companies can continue to market traditional cigarettes regardless.

    And what of the “specific tobacco products” that Sharpless talks about? Are we somehow to believe that the issuing of an MRTP in the case of eight General snus products indicates that other types of tobacco products might soon be in the pipeline? I don’t think so—not in this millennium. Even other snus products might struggle. Take a look at what the FDA has to say: “In addition to these lower risks relative to cigarette smoking, the FDA previously determined that the levels of two potent carcinogens in smokeless tobacco products called NNN and NNK [both tobacco-specific nitrosamines] are lower in these General snus products than [in] the vast majority of smokeless tobacco products on the U.S. market. In addition, the evidence showed [that] when used exclusively instead of other smokeless tobacco products, the General snus products offer the potential for reductions in oral cancer risk.”

    Focus on the negative

    The FDA, it seems to me, tends to be drawn to the negative rather than the positive. In its press note, the agency makes the point that as part of its assessments, it has to take into account both users of tobacco products and persons who do not currently use tobacco products. “In making this assessment, the agency must consider, among other things, whether those who do not use tobacco products would start using the product and whether existing tobacco users who would have otherwise quit would switch to the modified-risk product instead,” it said. Why this example, you might ask? Why not the positive example of taking into account the effect on nontobacco users of tobacco users switching to a product generating no secondhand smoke?

    With such a negative approach, the agency seems to work to undermine the evidence that it apparently accepts. Few would say the FDA should look at this issue through rose-colored glasses. But in making the announcement, it should have emphasized the positive. There are real positives down in paragraph six, for example: “The FDA’s review determined that the claim proposed by the company in its application is supported by scientific evidence, that consumers understand the claim and appropriately perceive the relative risk of these products compared to cigarettes, and that the modified-risk products, as actually used by consumers, will significantly reduce harm and the risk of tobacco-related disease to individual tobacco users and benefit the health of the population as a whole.”

    In addition, paragraph eight says, “The available evidence does not demonstrate significant youth initiation of these products, and evidence submitted by the company also found low levels of intentions to buy the product among nonusers of tobacco (including young adults) and, importantly, found that the inclusion of the modified-risk claim did not affect these intentions.”

    My views on the MRTP announcement might not chime with the majority view of what has happened, but I would suggest that those who have welcomed these MRTP authorizations with open arms should consider how, in doing so, they might be helping to lower the ambitions of tobacco harm reduction.

  • Health Authorities Have Needlessly Spooked Vapers

    Health Authorities Have Needlessly Spooked Vapers

    In their handling of the recent vaping scare, U.S. health authorities have unintentionally served the public poorly.

    By George Gay

    Konstantinos Farsalinos

    If there was one thing, and one thing only, that participants took away from September’s Global Tobacco & Nicotine Forum (GTNF), it was surely the idea that vaping precepts in the U.S., which have never appeared to form a coherent whole, were starting to resemble a witch’s brew. But how can this be? After all, vaping policy in the U.S. is guided by the Food and Drug Administration (FDA), which, in turn, makes decisions on the basis of science not on the basis of witchcraft or alchemy.

    There are clearly a lot of issues playing out here, but, according to Konstantinos Farsalinos, a research fellow at the Onassis Cardiac Surgery Center in Athens, Greece, one problem is that science is playing only a “very small” role in the vaping debate in the U.S., and even then, it is sometimes being misused to support “emotional aspects” of the debate. “You are seeing such a distortion of scientific facts that it is extremely disappointing for all of us outside the U.S.,” he told me during a telephone interview in November.

    But I should point out that Farsalinos, who gave a presentation at the GTNF held Sept. 24–26 in Washington, D.C., does not subscribe to conspiracy theories about scientists deliberately misleading the public. I asked him about the reaction by the Centers for Disease Control and Prevention (CDC) to an outbreak of acute lung disease among people using vapor devices—an outbreak that had become widely publicized only shortly before the GTNF was held. At that time, the CDC had apparently concluded that the outbreak, which by then had occurred only in the U.S. and, in respect of a single case, in Canada, could be due to vaping with nicotine alone. The first item on its list of advice concerning the illness was that people should “consider refraining from using e-cigarette, or vaping, products, particularly those containing THC [tetrahydrocannabinol].” This seemed to be an odd conclusion to draw given that, as Farsalinos pointed out in his presentation, people had been vaping with nicotine for more than 10 years around the world while the inhalation of THC by evaporating THC oils was a much more recent phenomenon.

    Nevertheless, other presentations made at the GTNF indicated that the CDC’s approach had spooked vapers, with some representatives of vape shop chains indicating that sales had dropped by up to 20 percent following the agency’s initial announcements and that the footfall of smokers looking to try vaping had fallen by about 50 percent.

    The easiest and most reasonable explanation for the way the CDC scientists behaved was their predisposition to taking a negative view of vapor products, Farsalinos said, before adding that he wasn’t suggesting the CDC scientists had set out intentionally to misinform the public or to cause harm. Speaking to me on Nov. 9, Farsalinos said the CDC had reported the previous day that all of the 29 cases of acute lung disease it had subjected to bronchoalveolar lavage analyses had revealed the presence of vitamin E acetate, which was a marker of THC oil usage. The CDC now almost accepted that all the cases it had examined had occurred among those who were using THC, he added, but, because of its earlier stance, nearly everyone was misinformed. Opinion polls showed that more people in the U.S. believed that nicotine vaping was dangerous than that THC oil inhalation was dangerous.

    So the CDC’s approach, Farsalinos said, and all the campaigns that were mounted had resulted in a “gross misinformation of the public,” something that was not unexpected when you examined what kinds of arguments the CDC scientists had been using, what kinds of press statements they had been issuing and what kinds of official reports they had been releasing. “I’m not saying this was intentional, but the scientists at the CDC—those at the FDA made a better case much sooner—allowed themselves to be influenced largely by the negative attitude toward electronic cigarettes in general, and they have unintentionally served the American public badly,” he said.

    Confirmation bias

    This of course raises a question. The people at the CDC are scientists, so why would they give way to emotion and prejudice: Why didn’t they stick to the science? Farsalinos said he believed this was a typical case of confirmation bias. The scientists had very strong negative opinions about electronic cigarettes, and this influenced the way they looked at the data. “One of the arguments they were using was that not all of the lung disease sufferers reported THC use,” he said. “But this is a naive argument because it is well known that people misreport. Some people will avoid reporting the use of THC, especially if they have been using illicit THC in states where it is illegal to use THC.”

    Farsalinos suggested also that the CDC scientists had lost track of an important aspect of such outbreaks. Epidemiology had demonstrated that while it might be possible theoretically for one epidemic to be generated by two very different causes, this almost never happened in practice, he said. So, it was not possible that both THC oils and nicotine liquids, which were two extremely different products, could have caused the same epidemic.

    And it would seem that the CDC required higher levels of proof of causal links in the case of the recent lung disease outbreak than it had in relation to other health problems. The causes of recent and fairly recent outbreaks of salmonella poisoning and Legionnaires’ disease, for example, had been rightly identified and accepted on the basis that about 80 percent to 85 percent of sufferers reported being in contact with the suspected cause. In the case of the recent lung disease outbreak, however, the CDC scientists needed higher levels of proof of causal links, and this again seemed to be a case of confirmation bias.

    Accepting the obvious

    While the FDA came out of the lung disease furor in better shape than the CDC, it too has had its problems, and I asked Farsalinos how it had reached the point where the FDA’s science seemed not to be getting harm reduction policy to the place where it should be. At this point, he turned to the issue of snus. Snus, he said, was a product whose harm reduction credentials were supported by a level of evidence that you could not even dream of in the case of any other tobacco or nicotine product. “We’re not talking about chemistry, toxicology, cell studies or animal studies,” he said. “We are talking about hardcore evidence: clinical evidence, long-term studies. We have meta-analyses of epidemiological and clinical data. We have known about this for 10 years at least.”

    Nevertheless, it took the FDA many years to accept the obvious—that snus use is a less harmful alternative to smoking, he said. (On Oct. 22, the FDA announced that it had authorized the marketing of eight Swedish Match USA snus products as modified-risk tobacco products.) And this was down to the rigidity of such organizations when it came to anything that was related to tobacco. It showed a dogmatic approach that said smokers should have no option but simply to quit their habit. “It would have been ideal if people were able to simply quit without using any aid or alternative products,” Farsalinos added. “The problem is [that] not all smokers are able to quit. We cannot provide them with very effective smoking cessation medications.

    “Instead of seeing harm reduction products as placing an obligation on the scientific community to provide as many tools as possible, additional tools to help people quit, parts of the scientific and public health community are doing the opposite. They are depriving smokers of an additional option [electronic cigarettes] to quit, which is absurd … it is literally absurd.”

    Farsalinos said there was, of course, a need for well-implemented restrictions and regulations in respect of vapor products, but the U.S. had done very little in this direction. It basically had no regulation, and it did not enforce the rules it did have, such as the ban on sales to young people. It had failed in enforcing this ban and was punishing smokers because of that failure. And worse, it was causing people who had used vapor products to quit smoking in the past to relapse by encouraging them to believe that they were going to be more harmed by vaping than by smoking.

    Farsalinos was also critical about the misuse of evidence in respect of vaping among young people. “We should definitely monitor it, and we should definitely try our best to prevent use by never smokers and by youth, but this is becoming an emotional obsession which has very little to do with the evidence.” The evidence pointed to the fact that vaping among young people was largely experimental and infrequent, he added, and it was largely confined to adolescents with a smoking history.

    Finally, Farsalinos said it was ironic that while, around the world, the concept of harm reduction was generally accepted, it faced more resistance in the case of tobacco. “I would accept a rejection of a harm reduction principle if we had the tools to make all or the vast majority of smokers quit,” he said. “But we don’t. When you have the most successful smoking cessation medication having a success rate of 25 percent in the long term, what is going to happen with the rest of the smokers? When you have smoking cessation medications that are unpopular among smokers, what are you going to do with the rest—punish them because they don’t want to use the medication or because they failed to quit with medication? It doesn’t make sense.”

     

     

     

  • Vuse Submitted for Review

    Vuse Submitted for Review

    The U.S. Food and Drug Administration (FDA) has filed for substantive scientific review the premarket tobacco product applications (PMTA) that was recently submitted by Reynolds American Inc. (RAI) for Vuse vapor products.

    “This is a first-of-its-kind application for Vuse products, and it puts Vuse one step closer to gaining a marketing order from the FDA,” said RAI CEO Ricardo Oberlander.

    “FDA will now review our scientific justification and determine the appropriateness of Vuse e-cigarette products against the public health standard.”

    The Vuse application comprises more than 150,000 pages of research and data, according to RAI.

    According to RAI Executive Vice President James Figlar, the company surveyed current tobacco users to understand product use behavior and demographics, conducted behavioral studies of current and non-users of tobacco to gauge consumer understanding of risks and interest in product use, and performed statistical population modeling to project the effect on the population as a whole.

    In addition, the RAI conducted clinical studies that looked at the abuse potential of Vuse products, which included examining nicotine pharmacokinetics, as well as conducted several studies to examine the aerosol properties of the products and the temperature during use.

  • Mounting Evidence

    Mounting Evidence

    U.S. Health officials have found more evidence implicating vitamin E acetate in the recent outbreak of vaping-related illnesses, reports AP.

    Researchers compared black market vaping cartridges seized in Minnesota during the outbreak this year with vaping liquid seized in that state last year. The newer cartridges contained the compound vitamin E acetate, but none of the older samples did.

    They also looked at vaping cartridges collected from a dozen patients. Vitamin E acetate was commonly found in those, too.

    The study echoes other work that found the substance in the damaged lungs of 29 patients across the U.S.

    “The findings further support a potential role for vitamin E acetate in causing lung injury associated with vaping products,” said Ruth Lynfield, a Minnesota health official.

  • Investing in Smoke-Free Future

    Investing in Smoke-Free Future

    Broughton Nicotine Services has made three senior appointments and completed investments totaling more than £10 million ($12.27 million) into people, facilities, equipment, software development and quality standard certification.

    Fozia Saleem has joined Broughton Nicotine Services as director of scientific affairs and program management. Saleem will be responsible for leading pre-market tobacco applications (PMTA) for e-cigarette companies seeking regulatory approval for their products.

    Toxicology expert Louise Neilsen has been appointed as a principal scientist and will lead the non-clinical elements of regulatory applications for companies in U.S. and U.K. markets.

    Leon Birch has become the new head of scientific development. He will lead a team of development scientists and analytical experts focused exclusively on advancing scientific methodologies for the analysis of ENDS.

    In January 2019, Broughton Nicotine Services opened a new contract research organization facility at its Lancashire. U.K. headquarters; in March, the site achieved GLP certification. Defining a set of quality standards for study conduct, data collection, and results reporting, the certification provides reassurance to Broughton’s clients that studies it conducts can be completed for PMTA and Medicinal Product submissions.

    In response to announcements in July that the U.S. Food and Drug Administration (FDA) would be implementing changes to ENDS testing requirements for the PMTA regulatory process, Broughton Nicotine Services also developed and validated innovative harmful and potentially harmful constituent (HPHC) testing methods, adhering to ISO 17025 standards and in line with the low limit of detection/limit of quantification levels required for precise toxicology assessments of the new FDA list of 33 analytes.

    Broughton Nicotine Services has also invested into high quality equipment and services for its facility. First, into the bespoke LIMS software system, LabHQ Link, which has been deployed to enable direct capture of test data from analytical equipment, reinforcing data integrity for all Broughton’s clients. And second, into high specification analytical equipment for use in Broughton’s specialist laboratories.

    “We have seen rapid change over recent months within the reduced-risk nicotine products market, and we are committed to supporting this evolving industry towards creating a smoke-free future,” said Broughton CEO Paul Moran.

    “Fozia, Louise and Leon will be great additions to the Broughton team as we continue to pursue new innovations and scientific advancements to help clients achieve success and remain at the forefront of ENDS regulatory compliance.’’

  • ‘Gateway’ Questioned

    ‘Gateway’ Questioned

    Vaping does not raise the likelihood a teenager will smoke, according to a new U.S. study by Arielle Selya at Sanford Research in Sioux Falls, South Dakota, and Sooyong Kim at the University of North Dakota in Grand Forks.

    Smoking can be entirely attributable to other factors, such as parental education, peer smoking, anxiety and other substance abuse, the authors found.

    The study examined the relationship between vaping and conventional cigarette smoking, looking at 14 shared risk factors, based on surveys of more than 12,000 middle schoolers and high schoolers conducted in 2015 and 2016.

    While the vapers were more likely to smoke cigarettes, the effect was muted once the analysis accounted for risk factors that are shared between the two activities. However, the researchers did find an association between vaping and lifetime cigarette use and said further study is needed to determine if there is a causal link.

    Earlier research, such as a 2018 study from the University of California, San Francisco, linked vaping to “established cigarette smoking” in adolescents. The new study has a simple explanation for that apparent link: People who tend to vape may just be more similar to those who tend to smoke.

    Lead author Selya said her research undermines the “gateway hypothesis” that vaping leads to smoking. She cautioned against regulating vapor products as combustible cigarettes, which could push teenagers back to smoking.

    The study was published in Nicotine & Tobacco Research, a scientific journal whose publisher doesn’t accept funding from the tobacco industry.

  • Unfiltered Cigs Most Risky

    Unfiltered Cigs Most Risky

    Smoking unfiltered cigarettes poses a greater risk of lung cancer than smoking filtered cigarettes, according to a study published in JAMA Internal Medicine.

    Among the 14,123 patients included in the study, those who smoked unfiltered cigarettes were 40 percent more likely than those who smoked filtered cigarettes to develop lung cancer and almost twice as likely to die of lung cancer.

    Researchers noted that although the risk was greater in those who smoked unfiltered cigarettes, those who smoked filtered cigarettes are also at a great risk. The study demonstrated lung cancer deaths occur in 1,600 per 100,000 persons who smoked filtered cigarettes compared with just 34 per 100,000 persons who never smoked.

  • Plastic alternative

    Plastic alternative

    Researchers at the California Institute of Technology have found a way to turn cells from tobacco plants into a strong material with wood-like mechanical properties, offering a potential alternative to unsustainable plastic, reports MIT Technology Review.

    The material’s stiffness and strength reportedly surpass that of commercial plastics of similar density, like polystyrene and low-density polyethylene, while being entirely biodegradable.

    To test the biodegradability of the new material, the researchers buried their samples in agricultural soil along with ordinary wood and watched what happened. Both samples initially gained weight by absorbing water from the soil, but then both broke down naturally.

    “We observe an almost complete biodegradation of the biocomposite 14 weeks after initial incubation,” a team member said.
