It’s a Polymergency and I Want to Talk Trash…

Let’s face it; nobody knows what to do about it.  Seattle just banned the bags, there are entire towns banning the bottles, and California has banned any decision making process all together.   If you don’t know about it or if you’re just blatantly unaware, there is a subject that’s coming to a movie theatre near you – literally.  Films such as “Bag It” and “Addicted to Plastic” are just a couple of eye opening documentaries that are meant to be wake-up calls to the general public to stop and take notice.  I remember seeing Food Inc.  for the first time; it’s a snap back to reality.  This particular wake-up call is screaming – PLASTIC!  And it all correlates with each other, feedstock, energy, governments, the environment, industry power-players, and the ability to make wise(r) choices.  We have a polymergency!  You may not see it out your front door, but if you care to look out the proverbial back door, you will find that we’re swimming in plastics.  200 billion pounds of it is being produced every year and growing at a ferocious rate, most all of it, despite your own good intentions, is heading for a landfill…and it’s not going away.

There are plenty of intertwined storylines, but it boils down to three choices and what’s right – right now.  First, you have your PLA’s (polylactic acid), made from corn starch.  This is the choice to compost, Industrial Compost, not your backyard contraption.  It’s sourced from feedstock with GMOs to harvest a specific type of crop – red flags should already be flying.  If you’re not sure where I’m heading here, then I recommend “Food, Inc.” an enlightening description about genetic engineering and our food supply.  Nevertheless, the PLA technology lacks the performance characteristics of tradition plastics (low melting point and poor barriers) and, by definition and despite the claims, it is not actually biodegradable. Ideally, and a stretch for sure, this type of plastic ends up in an industrial composting facility.  If the compost facility actually accepts it (although not likely), it is lovingly processed into the “organic” soil under a very controlled environment.  Otherwise, it’s considered a contaminant in the recycling stream and it’s undoubtedly going to a landfill.

Then there are the oxo-degradables, the choice to degrade.  Okay, let’s get this out of the way, “Biodegradability” means that the organic material is capable of being broken down into innocuous products by the action of living things (as microorganisms).  But, because everything eventually decays over time (albeit a ridiculous amount of time for plastic); this term is being unreasonably used when describing oxo-degradables as oxo-“bio”degradables.  Oxo-degradables do just that, degrade.  The technology certainly makes it look like its biodegrading.  Have you ever picked-up an old brittle piece of plastic that just breaks apart in your hand?  Basically, there are metal-ions interspersed along the polymer chain.  When an oxo-degradable plastic is exposed to UV light and oxygen (which occurs immediately), like any metal, the ions deteriorate.  The plastic becomes brittle and it breaks apart into tiny pieces of itself and contaminating, not biodegrading, into the soil and food chain.  Obviously, there are shelf-life issues with oxo’s and, like PLA’s, they’re not welcome in the recycling stream.  They’re heading for a landfill, and since this technology requires oxygen to degrade, and most landfills are an anaerobic (without oxygen), the plastic won’t degrade, let alone “biodegrade.”

Now a different technology has emerged, a technology which proves actual accelerated biodegradation without affecting the properties of traditional plastic.  This is the ENSO technology that’s causing such misunderstanding for the California legislatures, and curiously enough, for the time being, their answer is to only allow you to be informed if the product is compostable (PLA).  Considering the fact that the chances of your plastic trash being introduced into a composting facility, if you are actually able to find one in your area, are slim to none, this this is a peculiar line for California to take a stance on. The ENSO technology is an FDA approved and scientifically proven additive that maintains all the phenomenal characteristic of traditional plastic.  The technology works with the recycling stream and the accelerated biodegradation occurs when the plastic enters a highly microbial aerobic/anaerobic environment (landfills).  In comparison studies, when weighing factors such as sourcing, shelf-life, and end-of-life factors, the ENSO technology for biodegradation is simply a better choice.

Our scientific technology is moving towards better answers, but this is going to take time. Yet, with 100 million tons of plastic being dropped on our doorstep every year, we need to embrace proven newcomers to the scene.  The answer isn’t to take away the bag or the bottle; it’s to choose a better bag or bottle. And it’s certainly not time to cripple advancements with bureaucratic finagling.  Also, before we get too wrapped-up in the “green washing” of new technologies coming to market, we should start asking tougher questions.  Just because something is labeled with a “feel-good” name and has “feel-good” pictures accompanying the marketing campaigns, does not mean it’s better for our environment.   We are burying ourselves in plastic trash and separating the wheat from the chaff, or the marketing from the innovation, is going to be a critical step in improving our methods and preventing us from further trashing our planet.

Biodegradable Packaging-Nature Does it, We Should Too!

It dawned on me the other day when I was peeling a banana that nature uses its own “packaging” to protect food based material.  Yes I am talking about the banana peel as the example.   It seems as though a Banana will spoil within almost an hour when unpeeled, but if left in its peel (packaging) it will be protected for weeks being off the tree.

We peel oranges, bananas, corn etc. all paralleling the value ENSO plastics brings to the market.  The phrase, “nature does not produce anything that it cannot then break back down into its basic components” is so perfectly illustrated in this banana peel example.  Anyone will tell you, that when a banana peel is discarded in nature, they feel it will biodegrade (and I would also bet most would additionally picture someone slipping and landing on their backside because of a discarded Banana peel).

Nature accomplishes this miraculous process through the relentless activity of microorganisms designed to eat anything that has carbon available to “eat”.  Fruit, vegetables, leaves, meat etc. are just a few examples of the millions of items that are produced by nature, which will break back down into its basic microscopic components through the process nature provides.  These microbes are found everywhere, in fact there are more microbes found in a tablespoon of soil than inhabitants on the Earth.  Microbes are commonly known in high colony activity known as mold or fungus.

This nature produced packaging is a perfect parallel to what ENSO packaging is doing.  We see that we can initiate microbes to start the eating process of our treated plastic because they detect highly attractive food substances in our additive.  Once they begin to consume the additive, their digestive process, or enzymatic response, expands to consume the whole of the plastic and the additive.

This feature of our plastic working in harmony with nature is at the heart of our message to the world.  We can do things differently than we have in the past, and break out of “status quo”.  We can embrace innovation to foster change, and work with nature as opposed to working against nature.  The rewards overpower the downside when evaluated.  The upside to utilizing ENSO is growing in its understanding and impact.  Weather it is for a business wanting growth for doing the right thing, or the environmental impact of plastic on our planet, ENSO is here to help be a part of creating lasting, positive change.

During this New Year, we want to acknowledge those who are active in this change by utilizing ENSO material as part of their environmental mission.  In some instances, change has required courage and passion.  Anything worth-while has had to pass through the “growing pains” of society; hopefully those who have converted to ENSO has had more “growing” than they have had “pains”.  But in any event, the issue is too great, and the opportunity too real for anyone to not stand up and demand more.  So we want to invite others to create change for this New Year; to create a distinct legacy-whatever your position is at your company.  We invite those making key decisions for materials at their company to stand up and create change. We invite those who need to learn more about ENSO to make the decision to open their minds and get educated-misunderstanding or ignorance is part of the problem we face as a society, education can open up so many possibilities.  We invite all to hold ENSO to higher standard as well, and develop more information and answers to new questions and applications.  I hope everyone has a New Year’s resolution to be actively engaged in positive change to our environment, and elevate the status quo at your company/position to a new level of reality; even a higher standard.  We live in exciting times where someday I hope all of us can look back and say, “I was part of that great change in the market.”

 

Doing What’s Right When Nobody’s Looking

In a time when environmentally conscious branding is paramount in marketing circles, the overall adoption of “Green” initiatives should be, first and foremost, a fundamental decision. Where choices are made based on what’s right instead of what’s convenient. Often, technologies advance so rapidly that legislation is caught playing “catch-up”. It is during these times that brands face the decision of doing what is the scientifically proven best choice for the environment or shelving this choice because of marketing obstacles.

Often the final decision comes down to the corporate integrity of the brand and personal devotions of those brands leaders. The “why do we do what we do?” question. Do you implement environmental measures because it is the right thing to do, or do you implement them because it may improve your bottom line?

For example: Novartis is an international company who has made a corporate commitment to pay a ‘living wage’ to all employees worldwide. This means that they are often paying above legally required minimum wage because they understand that minimum wage does not provide for basic human needs. They implemented this corporate directive, not because it improved their immediate bottom line; but because their corporate moral standing includes a belief that an appropriate standard of living should always be respected in the course of business.

This is a specific example about human rights issues, and environmental rights follow the same path. Many companies are in business simply to make money for the shareholders, while others hold themselves to a higher standard or social cause, whether that is human rights, environmental issues, legislative involvement or truth in advertising. When your brand faces these tough decisions, it is much like a refiner’s fire where the true moral standing of your brand shines through. When all is said and done, those companies that tout their environmental accountability through the integrity of that decision and not the convenience that it offers will be clearly recognized by the consumers as brands with integrity and moral.

ENSO Plastics is both proud and honored to be partnered with many brands and manufactures who stand behind their commitments, with the foundation of scientific research, to become leaders in the adoption of improved methods for a healthier planet.

The Maturing of Biodegradable Plastics

Striving for growth and improvement is a fundamental part of the human experience. We, as a whole, are never satisfied with status quo.  This is true both personally and as a society. If one were to travel back in time to the beginning of any industry; we would discover a couple of things; industries began with the initial ideals of improving lives, they utilize best of current knowledge and understanding to bring those ideals to the masses and they improve over time.  We can clearly see that as time marches on from the beginning days of each industry, the  knowledge and understanding  changes;  resulting in improvements, wide acceptance and change.

History is riddled with examples of industries beginning as young ideas then growing and maturing over time to become well-established. In doing so, they’ve added essential improvements to the quality of life for mankind and often overcome significant opposition in the process.

It’s easy to take look at where we are today in industries such as aviation, space exploration, manufacturing, construction, education, legislation, science, and many others and forget the massive changes that have taken place since the beginning of each of these industries began.

  • Human flight was only dreamed of until the first powered flight by the Wright brothers in 1903 (which lasted only 12 seconds!). Through improved technology we now fly not only across the world daily but into space as well!
  • Copernicus suggested that the earth revolves around the sun in the early 1500’s. Books written supporting this theory were banned and supporters were persecuted and executed for heresy.  In fact Galileo was ordered by law to not hold, teach or defend this concept. Today, we accept this theory as common knowledge.
  • People laughed at Henry Ford’s “horseless buggy”. Today it is not only an essential mode of transportation, but we are finding better ways to prevent pollution and conserve energy resources consumed by these “horseless buggies”.

Industries begin just as the examples above, with the best knowledge available and often a bit of controversy. However they are regularly improving as a result of lessons learned, developments of new processes and protocols, scientific breakthroughs, and having a better understanding of what questions to ask; as well as knowing what issues to focus on and allocate resources to.

The story of ENSO is no exception to this process.  ENSO was created with the mission to change the world in the way we handle plastics – we want to solve the world’s plastic pollution issue.  Following more than a year of research to understand the plastic pollution issues; we developed ENSO additives. This additive is designed to enhance the biodegradation of standard plastics and allows the plastic material to recycle along with standard polymers.

ENSO utilizes the best of science’s understanding, processes and protocols to test and validate our technology.  As our industry matures we recognize that it is no different than the many industries that have come before us.   This industry is young and has much maturing to work through.  The culture of ENSO to improve the life of mankind with solving the plastic pollution issue does not make us shy away from the growing pains that happen with young industry and we are in the forefront, pushing the envelope by improving the science, process and protocols associated within this industry.   This does not come without hurdles, but as we see from the examples throughout history of matured industries, the key to success is continually improving the science, knowledge and education of our products. ENSO is dedicated to this continued maturation and the value that this provides to the industry and our environment.

ENSO Plastics Brings Legitimacy to a Young Market

We all know that the biodegradable plastics industry is just in its infancy.  What many might not be aware of is all of the “back end” work that ENSO has been doing for the market.  ENSO Plastics is doing many things to provide value to the plastics industry as it applies to the environment.  Offering solutions for plastic to serve its useful life, and once disposed of be valuable both as recycled material and within landfill environments, is part of the big picture.  ENSO also provides market value and legitimacy in ways unlike typical corporate organizations and much more as a not for profit, or NGO.

ENSO has an environmental mission that remains pure throughout our business activity.  Part of the mission requires us to honestly look at the REAL impacts of our activity and integrate REAL solutions.  We realize the need to foster legitimacy in our industry that will be of benefit to not only our customers; but to the market as a whole, and even our competitors.  We believe that just “slinging” product for the sake of profit is not being a responsible steward of our environment, and is culturally at odds with the way we feel here at ENSO.  We are in this to change the way the plastics industry and consumers alike view and treat plastic.

In creating this monumental change in such a vast industry, like plastic, there is a massive amount of education and legitimate data that needs to be presented.  Unfortunately, there is the fact that traditional business is done with the idea that competition does not want anyone else to succeed.  Because of this dynamic new industry and its complexities, ENSO is doing things non-traditionally and has seen the needs of the market and responded appropriately.

We have brought together the world’s top experts in different fields of science to bring the most compelling and comprehensive data collecting to help foster the growth of this particular industry, and to bring value to brands and manufacturing all the way to the end consumer.  All in an effort to further the knowledge and acceptance of what we consider to be a “turn in the traditional plastics market”.  Bringing together top polymer and engineering scientists like Georgia Tech’s Research Institute (GRTI) Materials Center; as well as the University of North Carolina State, and the Department of Civil, Construction, & Environmental Engineering is only part of the effort ENSO has undergone to develop the understanding and education of our marketplace and its regulating bodies.  Much of this effort is ongoing as this technology is new, and more applications will bring new questions specific to its market.

The important precept ENSO Plastics takes very seriously is that in order to go to market with a product, credible and repeatable scientific data needs to be the foundation of all innovation.  Second to that precept is the need for the innovation itself to be a major positive for the environment.  Without these two keys, a product is only interested in one thing – taking advantage of environmental marketing opportunities with no positive impact on the environment; in other words, GREEN WASHING.

Having the support and “backing” of world class institutions and experts in their fields eliminates these basic concerns; as these entities will not stand for anything other than scientific truth.  The market is full of political and personal manipulation, seeking only to bring certain products to market, while attempting to discredit or eliminate others from the market.  ENSO is set apart from this kind of business model by only seeking credible, non-biased individuals and institutions to work with.  This is a higher standard that state and federal regulators have to appreciate because the industry does not get more knowledgeable, independent and credible than the world’s leading experts.  -Del Andrus

Part #2 – A New Look At Zero Waste

If you recall, last month we discussed ZERO Waste. The key points were that every living entity creates bi-products, which can become waste if the byproduct has no value – think of your kitchen trash.

This trash is comprised of food waste, paper, plastic and anything else you did not find value for in your home. Luckily this trash goes to your curb and is neatly taken away where you no longer have to see it. Perfect right? A few years ago I would have said “NO WAY! This trash is going to the landfill where it will sit for decades or centuries. How is that perfect?” Fortunately, today we are learning how to turn that landfilled trash into a huge value – for you and the environment!

Methane. One of the cleanest and most inexpensive sources of energy available today, straight from your neighborhood landfill! That’s right, you send out trash and get back electricity! OK it is a bit more complicated than that but fundamentally that is exactly what is happening at over 550 landfills across the US.

Here are the facts:

As material biodegrades in landfills it produces methane. Methane has over 22 times the greenhouse gas effect of CO2, however when landfill methane is used for energy production, there becomes a carbon positive effect. The NRDC states that the use of landfill gas for energy has the potential to offset up to 12006lbs of CO2 per MWh, as it offsets traditional energy production such as coal and gas.

The greenhouse gas reduction benefits of a typical 4 megawatt LFG project equate to:
• Planting over 60,000 acres of forest per year or removing the annual carbon dioxide emissions from over 45,000 cars.
• This would also offset the use of 1,000 railcars of coal or prevent the use of almost 500,000 barrels of oil.

Producing energy from landfill gas avoids the need to use non-renewable resources such as coal, oil, or natural gas to produce the same amount of energy. LFG electricity’s offsetting of fossil fuel derived energy can avoid gas end-user and power plant emissions of CO2 and pollutants.

Did you know that 14 percent of renewable electricity generation (not including hydroelectric dams) comes from operations that recapture energy from discarded waste.

Companies today have a unique opportunity to utilize packaging that retains the beneficial properties of traditional plastic, such as strength, shelf life, visual aspect and process-ability, while creating a zero waste program and potentially reducing your carbon footprint. ENSO plastics are designed for disposal in today’s biologically active landfills where they will biodegrade and convert to methane for clean and inexpensive energy production. In 2009 there was 30 million tons of plastic packaging discarded into US landfills, converting this plastic to ENSO would result in about 10 million tons of plastic being converted to clean energy and offsetting the dirty energy production of coal and gas. It would also potentially free up over 70 million cubic yards in our landfills.

Did you know?

When converted to methane, 34 ENSO bottles (19.2 gram) can light a 100W light bulb for 1 hour.

Using ENSO materials provide companies a unique opportunity to step into a future of zero waste, where all product packaging is converted to clean energy, and returned to the earth in a beneficial form. In a life cycle analysis this could prove to be a carbon negative option to traditional plastic packaging.

Waste is a byproduct that has no value. Plastic that is recycled or biodegrades in a landfill has a value (economically and environmentally) and is not waste.

ENSO Plastics develops near-perfect plastic bottle

Wed, 2011-11-09 13:09

While many can’t imagine life without bottled water, it wasn’t that long ago—the 1960s, in fact—that plastic bottle production didn’t exist. Today, polyethylene terephthalate (PET) is the plastic of choice in the beverage industry. According to ENSO Plastics, more than 75 percent of the ubiquitous bottles (and 94 percent of all plastics) end up in landfills. “We really want to solve the world’s plastic pollution issue,” said President Danny Clark of the Mesa, Ariz.–based company. ENSO is taking advantage of this statistic with its current solution: fully biodegradable and recyclable PET plastic.

“When we started, some of the cofounders had experience with bottled water companies. I was one of them,” said Clark. “We were exposed on a regular basis to the environmental impacts that bottled water has in the environment.” Customers asked the co-founders regularly for alternatives.

America Recycles Day

As the sun set on November 15th, 2011 the nation paused to reflect upon our struggles and achievements with recycling. This annual event, “America Recycles Day”  on November 15, comes at us every year as a chance to refocus our efforts with recycling and waste management. We have seen the percentage of plastics recycled when compared with the amount of plastics produced, continue to decline (less than 8% of all plastics produced today are recycled). With the concerns of global warming and effects of pollution, it is important to understand the impact we can have on our environment. At ENSO Plastics we encourage people to be mindful of what they can do to help, no matter how small or large. Recycling is just one of many ways in which we can help our environment and preserve nature.

Join us in taking a moment to think about what each of us can do to help our Earth. Whether it is supporting alternate energy resources like solar power, choosing biodegradable plastics, creating less waste, or considering hybrid vehicles – remember that recycling is the least we can do to sustain our future. With each of us doing what we can, America Recycles Day in 2012 will be a chance for the world to unite in celebration of success!

What did you do today to help?

Breaking Down Plastics: New Standard Specification May Facilitate Use of Additives that Trigger Biodegradation of Oil-Based Plastics in Landfills

Georgia Tech Research News,

 

9/27/2011

Despite efforts to encourage the recycling of plastic water bottles, milk jugs and similar containers, a majority of the plastic packaging produced each year in the United States ends up in landfills, where it can take thousands of years to degrade. To address that problem with traditional polyethylene, polypropylene, Styrofoam and PET products, researchers at the Georgia Institute of Technology are working with the Plastics Environmental Council (PEC) to expand the use of chemical additives that cause such items to biodegrade in landfills.

Added during production of the plastic packaging, the compounds encourage anaerobic landfill bacteria and fungi to break down the plastic materials and convert them to biogas methane, carbon dioxide and biogenic carbon – also known as humus. These additives – simple organic substances that build on the known structures of materials that induce polymer biodegradation – don’t affect the performance of the plastics, introduce heavy metals or other toxic chemicals, or prevent the plastics from being recycled in current channels.

If widely used, these additives could help reduce the volume of plastic waste in landfills and permit much of the hydrocarbon resource tied up in the plastic to be captured as methane, which can be burned for heating or to generate electricity.

“Research done so far using standard test methods suggests that the treated plastics could biodegrade completely within five to ten years, depending on landfill conditions,” said Lisa Detter Hoskin, a principal research scientist in the Georgia Tech Research Institute (GTRI) and co-chair of the PEC’s technical advisory committee. “However, legislators, regulatory agencies and consumers need more assurance that these containers will perform as expected in actual landfills. We need to provide more information to help the public make informed buying decisions.”

To provide this information, Hoskin and other Georgia Tech researchers are working with the Atlanta-based PEC to develop a set of standards that would ensure accuracy and consistency in the determination and communication of the plastic containers’ biodegradation performance.

“We are working to develop a new standard specification for anaerobically biodegradable conventional plastics,” Hoskin said. “This certification is intended to establish the requirements for accurate labeling of materials and products made from oil-derived plastics as anaerobically biodegradable in municipal landfill facilities. The specification, along with a certifying mark, will allow consumers, government agencies and recyclers to know that the item carrying it is both anaerobically biodegradable and recyclable.”

The standard specification will provide detailed requirements and test performance criteria for products identified as anaerobically biodegradable, and will include rates for anaerobic biodegradation in typical U.S. landfills. These rates will be based on biodegradation test data and results from research being undertaken by Georgia Tech and North Carolina State University.

With support from the PEC and its member companies, Hoskin has directed testing efforts that show mechanistically how the additives work, and are showing that the degraded plastic leaves behind no toxic materials. With that part of the project largely completed, she now leads the development of the standard specification and certifying mark, and plans to organize a network of accredited laboratories that will test products made with the biodegradable additives to certify that they do degrade within a specific period of time.

Full development and adoption of the new standard specification by ASTM International will likely take between 18 months and two years, Hoskin said. The project will involve research being done using landfill simulations at North Carolina State University and other independent laboratories.

Using information from laboratory-scale anaerobic reactors operated under a range of temperatures, moisture levels and solids contents, researchers will compare the time required to break down known anaerobically biodegradable materials – such as newsprint, office waste and food waste – against the time required to degrade those same wastes in real landfills. That information will be used to project the biodegradation rate for the treated plastics in a range of real landfills, which vary considerably in moisture and other factors.

Though they are recyclable, plastics made from hydrocarbons had not been biodegradable until development of microbe-triggering additives. Bioplastics such as those made from corn may be composted, while a small percentage of specialized plastic products – known as oxobiodegradables – are designed to degrade when exposed to oxygen and ultraviolet light. But the bulk of the plastic resins used in bottles and other containers are made from materials that will last virtually forever in landfills, noted Charles Lancelot, executive director of the PEC.

Many communities operate recycling programs for plastics and other materials such as newsprint, aluminum and steel cans or cardboard. But because the cost of collecting, sorting, cleaning and reprocessing most plastics can be more than the cost of producing new products, such programs struggle financially unless they are subsidized, he noted.
Plastic bottles

Despite efforts to encourage recycling, a majority of the plastic packaging produced each year in the United States ends up in landfills. Expanding the use of chemical additives that encourage the biodegradation of this packaging could help reduce its impact on landfills. (Click image for high-resolution version. Photo: John Toon)

“If you can make a product like a bread tray and use it over and over again, that is the most efficient alternative,” said Lancelot, who developed successful business-to-business recycling programs while working at Rubbermaid. “But if you can’t reuse it and it’s not cost-effective to recycle it, where is the product going to go? The fact is that despite the best wishes of everybody involved, 75 to 85 percent of the plastics used today end up in landfills. We are addressing that unfortunate reality.”

Although biodegradation occurs to varying extents in all U.S. landfills receiving waste today, many of today’s landfills are optimized for biodegradation, he noted. Moist conditions and recirculation of leachate liquids accelerate the activity of anaerobic bacteria, which will attack plastic materials containing the additives. Such landfills typically do a better job of collecting and beneficially using the methane biogas, Lancelot said.

“When the anaerobic microorganisms that thrive in landfills contact these treated plastics, they begin to colonize on the surface of the plastic and adapt to the base resin,” he explained. “Until the bugs come in contact with the plastic, the additives remain inert and do not affect the properties of the plastic container. We are not changing the overall plastics production process, and the base plastic is the same.”

The compounds, which have been approved by the U.S. Food & Drug Administration (FDA), are typically added to the plastic resin in small amounts, between one-half and one percent by weight.

Expanding the use of anaerobically biodegradable additives must be done in such a way that doesn’t detract from recycling programs, said Matthew Realff, a professor in Georgia Tech’s School of Chemical & Biomolecular Engineering and co-chair of the PEC’s technical advisory committee.

“From a lifecycle perspective, it is important to quantify the benefit of recycling over landfill disposal with methane recovery to energy, and to continue to make the case that whenever possible, recycling is significantly better than disposal, even if you have methane production and capture from biodegradation,” he said.

While the biodegradation of plastic materials may solve one problem, the production of methane and carbon dioxide – both atmospheric warming gases – could worsen global climate change, he noted.

“Landfill capture of methane is not 100 percent efficient, nor does it begin immediately after the material is put into the landfill,” Realff said. “Therefore, there will be emissions from biodegradation that will reach the atmosphere. It is important to be aware of how accelerating the production of methane would change overall emissions.”

A 45-year veteran of the U.S. plastics industry, Lancelot says he is pleased to be working with Georgia Tech on a potential solution to the problem of plastics in landfills. The research will help close a gap in plastics “end-of-life” options where reuse or recycling are not feasible.

“Nobody had commercially biodegraded petroleum-based commodity plastics like polyethylene, polypropylene and polystyrene before these additives became available,” he noted. “This is ground-breaking work that is based on a solid scientific platform that defines biodegradability as a practical and useful end result.”
