This guest post was written by Ronald Sasine, senior director of packaging at Walmart.

When you buy a product, your decision drives a series of environmental impacts. Imagine the benefits if everyone considered the impact of packaging as part of their buying decisions, benefits measured in the billions of pounds of packaging manufactured, shipped and disposed of each year.

When we talk about more sustainable packaging at Walmart, we’re focusing on more than just smaller packaging. We’re looking at the entire life cycle of packaging and knowing that improvement can take many forms:

Rethinking a product. A few years ago, we began selling only concentrated liquid laundry detergent. By urging our suppliers to reexamine their products’ formulation, we eliminated hundreds of millions of pounds of packaging and saved natural resources.

Rethinking a process. By simply stacking Galaxy box fans differently on a shipping pallet, we saw annual savings of 10,000 pounds of plastic and 113 fewer trucks on the road, reducing diesel use by 12,600 gallons and freight costs by $150,000.

Rethinking a presentation. By working directly with our large toy suppliers, Walmart has been able to eliminate the frustrating wire ties used to secure toys in packaging. This effort will keep more than a billion feet of wire out of the landfill annually.

One other thing to notice about these changes—you don’t just find them at Walmart. As we work with suppliers to find better options, those improvements are showing up on the shelves of other retailers, increasing the impact we can have beyond our own “four walls.”

Walmart has a goal to reduce our packaging by 5% by 2013 (using a 2008 baseline), and we’re making significant progress. Of course, it hasn’t always been easy. We’re working to ensure that improved packaging still protects the products we sell, and we’re working with our customers and members to gain their acceptance. Some packaging changes have taken longer for customers to understand and endorse.

When we announced our package reduction goal in 2008, some of our suppliers saw a great opportunity and jumped in to partner with us on some creative changes. But not everyone was convinced it was right for business. Some suppliers worried about changing their processes, while others worried about investing in new equipment. However, when they realized how serious we were about packaging and that we would work with them and reward them for better packaging, they became very enthusiastic about the effect they can have on the industry by, well, thinking outside the box.

Better packaging benefits everyone along the supply chain, from the manufacturer to the customer. Walmart’s private label wine, Oak Leaf, is a great example. The manufacturer found a way to reduce the amount of glass used in the bottle by changing the design of the neck and reducing the punt (the dimple on the bottom of a wine bottle). In addition to reducing packaging weight by 8 million pounds, carbon dioxide by 3,100 tonnes and taking 280 trucks off the road, these simple changes reduced the price of Oak Leaf by 20 cents per bottle.

We’ve made many of the easy changes; now it’s time to tackle the more difficult challenges like installing new packaging equipment to that requires long-term planning and partnership with our suppliers.

Working toward more sustainable packaging isn’t optional; it’s a priority and it’s a large part of our business plan. For suppliers it’s a chance to differentiate themselves from their competitors. For Walmart it’s an opportunity to provide more value to our customers, to be innovative, think creatively and make changes that can improve the retail industry.

Buying Biodegradable Bags Instead Of Standard Plastic Bags

Posted By Bob B Taylor On August 19th 2011.

Biodegradable bags are a hot subject of environmental protection. National’s Government propagandize everyone use these bags instead of normal bag; further they issue policy to forbid the using plastic without biodegradable additive.

There are numerous ways to classify the biodegradable. One of the ways is degradable condition, there are two main types: Biodegradable plastic bags and Degradable plastic bags. Bio-degradable is manufactured out of farmed items like cornstarch and additive; they’re decomposed in the aerobic condition, so they can not degrade in environment. It is not the ideal choice for the landfill in environment.

Alternatively, the biodegradable trash bags are a lot more environment friendly. It may decompose easily because they are made, almost, entirely from the natural wastes. These usually do not imperil the aquatic life since the biodegradable bags may also decompose in aquatic atmosphere. Moreover, if these are swallowed through the inhabitants of aqua, it may easily be digested owing to their natural composition. Using these bags may also save huge amount of money that it takes the municipal authorities to remove them from your sewage pipes. The assembly and subsequent use of these bags has, surprisingly, a zero net impact on the Fractional co2 of the atmosphere as these release how much carbon dioxide at the time of their decomposition consumed during their production. The sunshine weight, easy transportation and lesser price will also be one of the most substantial advantages of these bags.

There is a good news for packaging bag market is biodegradable material appeared. This is a great choice for protecting environment. Through the use of additive elements including EPI, D2W or ECM just 1 percent or 2 percent to combine into resin material, plastic bags may be degraded totally from 6 months to five years. However, the purchase price is just a tiny bit higher than normal ones with the same quality of plastic bags: durability, light weight, water resistance, printing quality, nevertheless it bring to persistent development for economic and also the life. There are a lot of main reasons why using eco-friendly products makes good business sense. The most importance thing is that benefit moves along with sustainability and morality of economic. It is recommended for business owner to lessen their foot print on the planet.

PET bottles Sink or Swim?

Read the below article and it got me thinking. What’s interesting is that PET (what bottles are made of) does not float…even if it fragments. The plastics that are swishing around in the Garbage patch are not PET bottles and a lot of people do not realize that. I definitely do not think that just because bottles, or PET sink, that that is not pollution because its still there. But there are SO many other products out there…medicine bottles, laundry bins, storage containers, scissor handles,trash cans,caps, product packaging, etc. why is always the “bottles” that get pointed out? I think its important for people to make changes in their habits/lifestyles to better the earth…but until companies make the decision to do so as well, a lot of us will find it almost impossible to avoid all of the plastic that we accumulate. We need solutions, that will work…no green washing…so companies and consumers can make the right decisions about the earth friendly products they will implement in their lives.

 

 

 

Plastic: It’s what’s for dinner

Posted by on August 19, 2011

Conservation of mass often applies to college-level physics problems: in a closed system, mass can neither be created nor destroyed. In the case of the Great Pacific Garbage Patch – a gigantic section of the ocean littered with an unusually high amount of man-made trash — the system is clearly not closed. Yet conservation of mass is almost precisely what we see, both in the Pacific and Atlantic Oceans: more than 20 years of waste plastic studies in these oceans have demonstrated that the garbage patches are neither growing in size nor shrinking. They have conserved their mass. While plastic production rates have skyrocketed, as well as human consumption of plastic-contained goods, the plastic masses in these oceanic gyres (very large circular current patterns spanning thousands of miles) are incontrovertibly the same now as they were in the 1980s.

 

Interesting. If the rate at which plastic enters the patch has increased while the total mass of the patch has remained constant, then there must have been a corresponding increase in the rate at which plastic leaves the patch, to balance. Some scientists have hypothesized that the depths of the oceans act as plastic “sinks” from which waste never returns. If this were true, huge collections of settled ocean plastic debris should be established across the world. But for all their efforts, scientists have not been able to locate such sinks. With no evidence to support the ocean sink hypothesis, researchers have been looking for alternative answers for decades. What they have recently found may surprise you.

In a recent article appearing in Nature News, marine chemist Tracy Mincer and colleagues at the Woods Hole Oceanographic Institution (WHOI) reported the observation of oceanic bacteria actively consuming bits of plastic recovered from ocean gyres. At a glance, their result are not so shocking. After all, we have long known that microbial communities can (slowly) degrade plastic in landfills, over many years. However, it had been previously thought that the ocean gyres were too nutrient-poor to sustain substantial bacterial colonies. Therefore, the group’s findings help shed light on what has been a rather intriguing puzzle to scientists.

Scanning electron micrograph of the same sheet of plastic shown above reveals millions of plastic-eating bacteria

Of course, all scientists know that by answering one question, hundreds more arise. Most importantly, currently no one knows what chemical compounds microbes degrade plastic into. They could be biologically benign compounds, or they could be toxic. Concentrated breakdown of plastic into toxic compounds in ocean gyre masses, or landfills, could spell eventual disaster for local ecological communities. Through biological magnification, toxins can be stored inside animals’ bodies. As prey is consumed at higher and higher levels up the food web, the largest predators end up with the highest concentrations of toxins – think the bald eagle and DDT. Then multiply the issue by the size of the Great Pacific Garbage Patch, which is swirling away inside the largest ecosystem on the planet.

Whatever scientists determine about the toxicity of the microbial degradation products of plastic, the rest of the conserved mass of floating plastic will still be there. If we continue our current plastic consumption as societies, then billions of micron-sized particles of human trash will continue to float in our oceans for decades or centuries, just flinking along while fish, whales, and seabirds consume them for dinner. Of course, we can also clearly see that preventative measures would have a profound effect here: if we actively reduce the mass of plastic entering the system while microbial degradation activity remains high, then the total mass of plastic in the oceanic gyres will also decrease. In other words, your actions today directly contribute to the health of our oceans in the future.

I urge you to think about consumption habits that you can change, like carrying a reusable water bottle instead of purchasing bottled water. I never go anywhere without my half-liter Nalgene. Also, you will be happy to know that the I Heart Tap Water campaign is well underway here at UC Berkeley. You can find campus water bottle filling stations on a Google map here.

It’s your choice. You can either let ocean microbes struggle to clean up our oceans for us, or you can actively prevent the contamination of our water with plastic debris by choosing to reduce your plastic consumption and recycling as much as possible.

Tesco Drops Oxo Bags

 

 

Tesco drops oxo biodegradable bags

Friday, August 19, 2011

 

 


British supermarket chain Tesco ended the use of oxo biodegradable plastic following research findings saying biodegradable plastic bags could be more harmful to the environment.

Oxo biodegradable bags are made of nonrenewable plastics, which are able to degrade in the presence of oxygen and sunlight thanks to the addition of small amounts of metals.

“We took the decision to remove the biodegradable additive because we believed it contributed towards bags becoming weaker and to help better promote their reuse and recycling at end-of-life,” a spokesman for Tesco said.

The decision was based on research conducted by the Department for Environment, Food and Rural Affairs disproving that plastic bags will degrade to water, carbon dioxide and biomass in 18 months. The report concluded that degradability depends on where and what conditions the bag ended up after use.

Currently, Tesco uses non-biodegradable carriers that contain 15 percent recycled material. – K.D. Mariano

McClellan Mountain Spring Water

McClellan Mountain Spring Water just sent me their video showcasing their earth friendly ENSO bottles!



“McClellan Mountain Spring Water utilizes PET plastic bottles with a specially formulated additive that makes the bottle 100% biodegradable. This ENSO additive allows the bottles to maintain the same physical properties (shelf life, texture, clarity, appearance, etc) as traditional PET plastic bottles, however once these bottles are placed in a landfill , ocean, stream or other outdoor location, the bottle starts to breakdown in 250 days. At the end of 5 years, the biodegradable bottle returns to the environment a biogases and inert humus. In landfill disposal, our bottles promote the use of biogases, for use in creating clean energy.”

 


Landfill gas will fuel America

With all the recent online stir about biodegradable plastics releasing methane too quickly the below article caught my attention. The problem is not the biodegradability of plastics, but more so the lack of attention to collecting it in a timely manner and using it for its amazing, natural benefits! In the past 100 years we as humans have worked so hard in making things convenient, disposable, and unnatural. The truth is,we live in nature, and nature has its own processes for cleaning things up…and it revolves around biodegradation. This article reminded me of the movie Dirt, which is a must see! It also reminds me of this article/video I recently found on treehugger….http://www.treehugger.com/files/2011/08/putting-a-price-on-poop-and-pee.php

Landfill gas is ‘awesome example of American ingenuity’
Share | Comment
Jim Johnson | WRN senior reporter

Aug. 8 — If using natural gas to garbage trucks is considered a home run, then using natural gas created by decomposition of trash and other organic waste could be viewed as a grand slam.

For Joanna D. Underwood, the potential for this kind of renewable gas use is huge around the country.

It was not that long ago that folks realized using natural gas could be a terrific step forward, said Underwood, president of Energy Vision, a nonprofit group in New York City concerned with transportation fuels and renewable energy. But the exact path was fuzzy, she remembered.

“The picture that has become much clearer in the last four years is the picture that involves renewable natural gas. And that is really this country’s first sustainable fuel. It’s renewable. It’s the lowest carbon-based fuel in the world,” she said.

Harvesting methane from sites such as landfills, waste water treatment plants and farms can help create a supply of domestic transportation fuel, she said. Creating an infrastructure to handle renewable natural gas allows communities and companies alike to better picture its future use.

“That’s pretty exciting. Every community, right now, can begin looking at renewable natural gas and the organic waste that they have in their jurisdiction,” she said.

“There is no other major option for significantly reducing our dependence on foreign oil right now other than natural gas: conventional natural gas and renewable natural gas,” Underwood said.

McNeilus Companies Inc. makes both traditional diesel-powered refuse trucks and CNG-powered vehicles.

Jeffry Swertfeger, the company’s director of marketing and communications, sees more and more interest from solid waste management companies wanting to close the loop between disposal sites and collection operations by using methane created by decaying waste as a transportation fuel.

“We call it the ultimate green machine, when you have a truck that’s picking up refuse that’s being powered by the methane from the refuse,” he said.

“I think that’s an awesome example of American ingenuity,” he said. “These are the guys who make this country great.”

One location he pointed to is Waste Management Inc.’s Altamont landfill in California, where methane gas is converted into liquefied natural gas to run company trucks in nearby markets.

That $15.5 million project uses about 3,000 cubic feet of landfill gas per minute to create about 13,000 gallons of LNG per day.

“It’s easier for cities and communities to envision making the fuel if they already have a way to distribute it,” Underwood said. “It can take the place of conventional natural gas. It also can be blended with it. They are chemically just about the same.”

Target T.V. Ads “Go Green”

It’s always exciting when a big company that has such a influence on consumers decides to make earth friendly changes. Target is teaming up with EcoSet (eco-consulting firm) to make their television commercials more earth friendly. For example, on set, they’re using PLA utensils….I just hope they are discarding of those in a industrial compost facility! Read the article below to learn what other changes Target is making to their t.v. advertisements . Do you think these changes are enough, or do you think they could do better? Let me know in the comment box below!- Megan Bentley

 

Target and EcoSet: TV Commercials Can Be Green Too

By Merlin Miclat on Mon, 08/15/2011 – 1:27pm

Many retailers these days have made significant progress in reducing their impacts on the environment. From implementing alternative energy to fuel their operations to carrying eco-friendly products, retailers are increasingly going green. However, Target and eco-consulting firm EcoSet, are taking it further by making television ads eco-friendly as well.

Target, which already carries a number of eco-friendly products, has teamed up with EcoSet to produce TV advertisements that are more environmentally responsible. The firm claims to have the ability to prevent 90% of waste produced on the set from ending up in landfills without interfering or costing production crews time or extra money. Also, since TV ad shoots last only a few days, crews usually do not take the time or put in the effort to clean up after the shoot. With tight schedules, why clean up if it takes up as much time as the shoot itself? This is where EcoSet comes in.

EcoSet is comprehensive in achieving its goals. On the set, there is not a single plastic water bottle; everyone is given a reusable, stainless steel water container. For Target shoots, everyone gets a red bottle labeled with a Target logo. Filtered water dispensers are provided for everyone to refill their water containers when necessary. How many times do people open a water bottle, take a sip, put the bottle down somewhere, leave, then come back and wonder which bottle was theirs? Then, just to be safe, they open up a new, sealed water bottle, and might repeat the whole process again. The use of reusable water containers and water dispensers would help eliminate this problem, which wastes water and plastic.

EcoSet also provides numerous recycling solutions. Waste from the set and office are recycled. Hazardous and electronic waste are also properly disposed of or recycled.

EcoSet also has composting bins to compost any food waste, which can be a big problem. In some cases, this problem has prompted groups to launch campaigns against production crews that waste food. For instance, Australian chef Matt Moran was angered when the prosciutto-wrapped chicken dish he prepared as a demonstration was tossed into the trash by a crew member.

Although the profanity-laced incident was admittedly staged, it emphasizes the problem with food waste. Chef Moran later explained, “I was more than happy to be involved in something so controversial if it meant that the message of food waste would be brought to the top of Australians’ minds.” Food waste can be used as compost; however, some chefs, especially those that spend much time and effort putting together dishes they are proud of, may be irked at the sight of their labors being composted and used to feed plants instead of being enjoyed by people.

Speaking of food, all dishware and utensils used on the set are either reusable or plant-based. Plant-based utensils are composed of renewable materials such as rice, corn, potatoes, and sugarcane. These utensils will biodegrade within 100 days, compared with traditional plastic utensils that take hundred or even thousands of years to decompose, taking up space in ever crowding landfills. These plant-based utensils usually conform to DIN CERTCO, ASTM, and ISO standards, assuring that they actually decompose in a timely manner as claimed.

Lastly, EcoSet has helped Target donate construction materials that are no longer needed on the set to various art and education organizations. Materials have been used for a variety of projects. Cindy Saucedo Smith, program coordinator for the organization ArtStart, has seen kids use materials such as silver cooling tubes as part of robot costumes. Says Smith, “The kids can go crazy when they see stuff like that, so we’ll hold on to it for the fall and see if there are suggestions for eco-costumes.”

As retailers may launch TV ads that claim how environmentally responsible they are, it is even better if producing these ads are green as well.

Pepsi follows Green washed Consumers

This is a great article. Companies should be going with the best environmental packaging out there, not just what consumers believe is the best environmental packaging because they have suffered from greenwashing or a lack of access to the facts.  How amazing would it be to have a bottle made from renewable resources & with the ENSO additive. A renewable, biodegradable & recyclable bottle, that would be amazing.

Consumer preferences driving PepsiCo sustainability efforts

By Mike Verespej | PLASTICS NEWS STAFF 

Posted August 11, 2011

PURCHASE, N.Y. (Aug. 11, 12:40 p.m. ET) — For a brand owner like PepsiCo, sustainable packaging doesn’t just mean making decisions on a complex set of resource, energy and environmental issues. It also means that you have to understand and determine whether consumers will view what you do as sustainable.

“Everything needs to be in sync with the brand identity, and you have to ask yourself what is the right message so the consumer understands that what you are doing is sustainable,” said Denise Lefebvre, vice president of global packaging for food and beverage giant PepsiCo. “There already is confusion among the public about sustainability, so all our messages have to be clear, consistent and in sync.”

Lefebvre, who was director of advanced research for beverage packaging for the Purchase, N.Y., soft-drink giant until a recent promotion, also said that when it comes to sustainable packaging, much of what brand owners focus on is driven by “consumer desires and consumer thinking.”

“Consumers are looking for technologies and innovations where it is readily evident to them what to do with that product and how it benefits them and the environment,” Lefebvre said in a recent interview. “The benefit has to be clear to them and right in their sweet spot. Our messages give us an opportunity to simplify things for consumers.”

With that in mind, the company has focused on producing increasingly lightweight PET bottles, developing technology to make PET bottles from plant-based resources and agricultural and food waste, and putting Dream Machine recycling bins and kiosks into place in cities to increase the number of bottles and cans that are recycled, she said.

“When consumers see a bottle that is fully recyclable and ultra-lightweight, it helps them in terms of making their purchase,” Lefebvre said. “The consumer understands source reduction and the use of less material. It is tangible and they can understand that. So if we can create technologies to push that faster, that would be ideal.”

Similarly, consumer perceptions are one of the driving reasons why PepsiCo is working, in partnership with others, to make a PET bottle completely from plant-based materials, including switch grass, pine bark and corn husks.

“If I tell [consumers], it’s 100 percent renewable PET, they understand it and they get it because they want things straightforward,” Lefebvre said.

Since the firm announced in March that it had developed a 100 percent renewable bottle, it has received positive consumer feedback, she said — although that bottle won’t eat go into pilot production until sometime in 2012, and even then, in limited quantities of 100,000-500,000 bottles.

“Consumers like it because you have eliminated fossil-based products [and] they believe that pulling oil out of the ground” is not the route to use anymore, Lefebvre said.

PepsiCo is also working to make its planned renewable PET bottle from organic waste from its food businesses, including orange and potato peels, oat hulls and other agricultural byproducts.

“Consumers have made it clear that they want us to use non-food resources, or food or agricultural waste [for bioresins] because it doesn’t detriment the environment and it doesn’t take away from food supplies,” she said.

Although many of PepsiCo’s sustainability package initiatives are driven by consumer perceptions, the firm realizes it can’t do things that are not sustainable just because consumers perceive them to be, she said. “Consumers would love an oxo-biodegradable bottle,” Lefebvre said “But right now, the technologies out there would do more harm than good.

“So to deliver something that would be more detrimental to the environment … It would be wrong and it would be greenwashing.”

Similarly, PepsiCo is not using polylactic bioresin for bottles because she said the material does not have the necessary barrier properties and is problematic in the PET recycling stream.

During a presentation at the Bioplastek conference in New York in late June, Lefebvre said PepsiCo’s objective is to create “performance with a purpose” in its packaging.

“Our objective is to make a 100 percent renewable, sustainable, non-fossil-fuel-based PET bottle in a closed-loop system using agriculture waste,” she said. “We want performance identical to what we have now: a product that is fully recyclable and a product that significantly reduces the carbon footprint.”

A number of companies now make non-petroleum-based ethylene glycol — which is 30 percent of the formulation of PET. And roughly a half-dozen firm say that they have demonstrated in a lab that they can make paraxylene, the building block for terephthalic acid, which constitutes the rest of PET, or plant-based terephthalic acid.

PepsiCo’s main competitor, Coca-Cola Co., has been making its PlantBottle from conventional terephthalic acid and renewable ethylene glycol since December 2009. H.J. Heinz Co. also began using the Coca-Cola PlantBottle for its 20-ounce ketchup containers in July.

Heinz expects to sell 120 million PlantBottle ketchup bottles in 2011; Coca-Cola expects this year to package 5 billion beverages globally in 15 countries in the PlantBottle compared to 2.5 billion last year.

PepsiCo has not discussed technology details for making the renewable terephthalic acid needed for a PET bottle manufactured 100 percent from renewable resources.

“We can buy and source the renewable ethylene glycol from any number of sources,” Lefebvre said. “That has been around for awhile. The key is the T piece [terephthalic acid]. That is critical in driving a renewable PET bottle to a mass scale.”

PepsiCo plans to model several different types of chemistry in its pilot -cale project to determine their efficiency to make renewable terephthalic acid. “There are a lot of emerging technologies that we will be evaluating, and they all have their pros and cons,” she said. “We’re very open to looking at them all and would be comfortable using several of them,” she said.

“We don’t make PET. We’re not going to. So we need the quality to be right.”

Lefebvre said she expects PepsiCo to announce soon on its sourcing strategies for renewable PET bottles. None of those strategies, she said, mean the firm will reduce its efforts to boost recycling of its plastic bottles or aluminum cans.

Since it embarked on its Dream Machine recycling initiative in April 2010, PepsiCo has placed 2,600 Dream Machines bins and reverse-vending kiosks in more than 30 states — at supermarkets, on city streets and other public venues.

The recycling bins are similar to trash cans, but they’re painted Pepsi blue with a recycling message on them. The computerized kiosks give reward points for each bottle or can recycled, which consumers can redeem online at greenopolis.com. — a partner in the program along with Waste Management subsidiary WM GreenOps LLC.

PepsiCo has also developed a recycling initiative for schools, called Dream Machine Recycle Rally, which rewards schools with points for each non-alcoholic plastic bottle or aluminum can students bring to school for recycling.

“It is a self-supportive strategy,” Lefebvre said of the initiatives. “As the program proliferates, it reaffirms to the consumer that recycling is important, and that recycling is just as good as renewables.” The Dream Machines also help the firm bring up recycling rates and get the material it needs to incorporate recycled content in its products, she said.

Just last week, PepsiCo announced that in August it will market the first plastic soft drink bottle to be made from 100 recycled PET in North America. The bottle, 7UP EcoGreen, will be used for diet and regular 7UP sold in Canada. It is expected to reduce the amount of virgin PET used for that product by 6 million pounds a year.

“We want to use more recycled PET” in all plastic bottles, Lefebvre said. “It is a matter of obtaining the right quality and getting the material — which is in short supply. “

To augment PepsiCo’s supply of recycled PET, the firm last year agreed to buy the majority of its bottle-grade PET pellet and flake from the new CarbonLITE plant in Riverside, Calif., which is scheduled to launch by Sept. 30 with nameplate annual capacity of 100 million pounds.

Yale Students discover Plastic eating Organisms


This past week I had the most intriguing article show up in my Google alerts; Yale students find organisms to degrade polyurethane.  In a 2008 trip to Equador, Yale undergraduates discovered organisms in Amazon rainforests fungi that have shown the ability to degrade polyurethanes all by themselves. Endophytes collected by students were taken back to New Haven and were analyzed as well as tested for biological activity, ability to be used in bioremediation, and other possible uses. In a rudimentary test, student Pria Anad showed that a chemical reaction did take place when a endophyte was introduced to plastic. The great thing is that the enzyme identified by Yale students is able to degrade plastic without the presence of oxygen, which in the future I could see greatly benefiting landfills/plastic trash disposal. This could open the doors to an entirely new way to reduce all of the plastic waste the world has accumulated.

Foe ENSO this is not a terribly new concept. Our ENSO Biodegradable plastics additive was inspired by nature’s ability to breakdown plastic materials. By examining nature we have created a scenario inspired by the very concept of microbial digestion. The ENSO additive allows any plastic polymer to become degradable in a landfill. How have we made that possible? By adding our organic ENSO additive into standard plastic during the manufacturing process, the plastic will become recognizable by nature so that it will biodegrade (while keeping the same attributes of the original plastic.) When ENSO products are thrown away, the organic blend creates a perfect environment and food source for microbes in a landfill. As microbes consume the additive, they secrete enzymes. These enzymes break down the polymer chain into materials that are easily consumed by microbes. The end result is carbon dioxide, methane, and healthy, new soil.

Yale students find organisms to degrade polyurethane

Urethanes Technology International

Aug. 2 — Yale undergraduates have discovered organisms in Amazon Rainforest fungi which can degrade polyurethanes. The discovery, which is featured in the journal “Applied and Environmental Microbiology,” may lead to innovative ways to reduce waste in the world´s landfills, the university said in a press release.

The undergraduates were participating in Yale´s Rainforest Expedition and Laboratory course, funded by the Howard Hughes Medical Institute.

“This shows amazing things can happen when you let undergraduates be creative,” said Kaury Kucera, postdoctoral researcher in the department of molecular biophysics and biochemistry and co-instructor of the course.

Students collect endophytes found in rainforest plants and take them back to New Haven to test for biological activity and then analyze any that show biological activity to see what medical or other uses might be possible.

On the 2008 trip to Equador, student Pria Anand decided to see if the endophytes she collected could be used in bioremediation. In a rudimentary test, Anand showed a chemical reaction did take place when an endophyte she found was introduced to plastic.

Jeffrey Huang analyzed endophytes collected by other students on the 2008 trip to find those that broke down chemical bonds most efficiently.

Then Jon Russell discovered that one family of endophytes identified by Huang showed the most promise for bioremediation. Russell went on to identify the enzyme that most efficiently broke down polyurethane.

While other agents can degrade polyurethane, the enzyme identified by Yale students holds particular promise because it also degrades plastic in the absence of oxygen — a feature which the university points out is “a prerequisite for bioremediation of buried trash.”
