Critics of oxo-bio hit back at ‘no evidence’ claims

By Hamish Champ
Posted 24 October 2011 9:51 am GMT
An organization involved with a University of Loughborough report into oxo-biodegradable materials has rejected claims that its conclusions were not supported by evidence.
Dr John Williams, head of materials and energy at the NNFCC, the UK’s National Centre for Biorenewable Energy, Fuels and Materials, said he was “disappointed but not surprised” to read of a recent attack on the Loughborough report in PRW by companies involved in the manufacture of oxo-biodegradable materials.

“The Loughborough report was peer reviewed and checked by the chief scientist of the Department for Environment, Food and Rural Affairs (DEFRA),” he said.

The report, commissioned by the then-Labour government and published in March 2010, argued that “some plastics marked as degradable might not be as environmentally-friendly as consumers think”.

However recent criticism of the document by three companies which manufacture oxo-biodegradable materials prompted Williams to defend its findings.

“It is to be expected that any industry group will disagree with a report that does not support their view. The Loughborough report set out to with one aim, to find independent, verifiable evidence for the claims made by oxo-degradable material manufacturers and could not find any,” he said.

Williams added: “The fact that oxodegradable manufacturers have produced their own scientific dossier is meaningless without independent supporting evidence and this was not provided when asked for.”

Dr Williams’ comments followed the publication of a scientific dossier compiled by Symphony Environmental, EPI and Wells Plastics and published on their respective websites.

In a joint statement issued earlier this month the three firms argued that the Loughborough research team “had no expertise” in the field of oxo-biodegradable plastic technology.

However the NNFCC, which said it persuaded supermarket giant Tesco to stop using plastic bags made of ox-biodegradable material earlier this year, rejected this and counter-argued that it was the oxo-biodegradable industry that had yet to table peer-reviewed evidence for its own claims.

Toyota Using Sugar Cane Bio-Plastics To Replace Oil-based Plastics

http://www.themotorreport.com.au/52711/toyota-using-sugar-cane-bio-plastics-to-replace-oil-based-plastics

Toyota, who has long been experimenting with the use of bio-plastics in vehicle production, is now using a newly developed bio-plastic derived from sugar cane in its Japanese-market Sai Hybrid Sedan.

Originally released with 60 percent of its exposed interior surfaces made from bio-plastics, the new model, to be released on November 1, will have no less than 80 percent of its interior exposed surfaces – including seats – made from the new sugar-based bio-material.

The new bio-plastic is employed in high-use areas such as the seat trim and carpets. Toyota testing confirms that it matches petroleum-derived plastics for durability and cost, while outperforming other bio-plastics for heat-resistance, durability and shrink-resistance.

Toyota developed its bio-polyethylene terephthalate (bio-PET) by replacing monoethylene glycol (commonly used in PET manufacture) with a biological raw material derived from sugar cane.

It may not be commonly known, but the manufacture of the Lexus CT200h achieved a world-first when bio-PET ecological plastic (derived from plants) was employed in its boot lining.

AT&T uses renewable plastic packaging

When it comes to plastic packaging it accounts for a huge chunk of our worlds single use plastic waste. Switching to a better alternative like plastic made with a renewable source is great. However when it comes to landfills/recycling….plastics like PLA corn plastics will act as traditional plastic. PLA acts wonderfully if placed into a industrial compost facility where it will be compostable but unfortunately a majority of people to not have access to these facilities. I am happy to hear that they will be using a renewable source for their plastic, but I wish the plastic would also be biodegradable in landfill like ENSO plastics. Let me know what you think!

AT&T to use sugarcane, cut petroleum, in plastic packaging

Posted on September 13, 2011 at 5:45 am by Simone Sebastian in Ethanol, Biofuels, Petrochemicals

 

AT&T will start packaging its cell phone accessories in bio-plastic instead of petroleum-based plastic next month, the telecom company announced this week.

AT&T says the change is its latest effort to reduce the company’s carbon footprint. While the new plastic packaging will contain petroleum, up to 30 percent will be manufactured from plant materials, the company said in a statement.

While most plastics are manufactured from petroleum products like ethane and propane, technological advances have made plant-based plastics more widely available. Like biofuels, bioplastics are manufactured from agricultural crops, like corn and sugarcane.

AT&T said it will start using sugar cane ethanol to produce some of its plastic packaging beginning Oct. 2.

Jeff Bradley, AT&T’s senior vice president for devices, said in a statement the company will be the first in its industry to use plant-based plastic packaging for consumer products.

“We are actively working with our accessory suppliers to incorporate both less packaging and more sustainable plastic and paper,” Bradley said.

The company cut 500 tons of paper and plastic by shrinking its packaging in 2010 and 2011, according to the written statement, and has used soy and vegetable-based ink for some of its accessories cases.

Coco-Colas plant bottle business plan

This isn’t the most recent use for those up to date with cokes plant bottle. This article however goes into a more detailed business view of Cokes decision and long term goals. Definitely worth the read, comment and let me know what you think!

Coca-Cola in green bottles

    You could forgive Scott Vitters the occasional spate of Monday morning blues. As global head of sustainable packaging at The Coca-Cola Company, he has an unenviable job. Some might even call it impossible. Every day, consumers around the world slurp their way through 1.5 billion Coca-Cola products. Packaging those servings accounts for the most sizeable chunk of the company’s environmental footprint. Now Vitters’ bosses back at Coca-Cola’s Atlanta HQ are saying they want to double sales over the next decade.

    Yet today finds him surprisingly upbeat. Hitting UK shelves today is PlantBottle, what Vitters calls a “breakthrough technology” destined to green not just Coca-Cola but the entire packaging industry.

    “We know that we need to do more with less and we know that we can do that through technological innovations like PlantBottle”, he says.

    So how does it work? The theory is simple. Plastic bottles are currently made out of a variety of petroleum-based materials. What the chemistry wonks in Coca-Cola’s labs have done is replace some of those with plant materials.

    The result is to reduce reliance on fossil fuels and cut carbon emissions by 8-10% in the process. Furthermore, the plant-based solution is an identical match with polyethylene terephthalate (PET), a recyclable plastic already widely used by Coca-Cola.

    “This isn’t about an innovation that’s just a little green widget or flavour of the day … We’re taking the next step of the journey to decouple our plastic from fossil fuels”, Vitters insists.

    The numbers seem to back him. Coca-Cola expects to shift over 200 million packs in the UK this year as it switches 500ml bottles of Coca-Cola, Diet Coke and Coke Zero to the greener formula.

    The UK is no guinea pig. PlantBottle has already been around for a couple of years, rolled out first in Denmark to coincide with the UN climate change summit in Copenhagen. Coca-Cola currently produces around five billion packs in twenty markets.

    Vitters is adamant that the new bottle makes long-term financial as well as environmental sense. Although the plant alternative currently costs more than petroleum, he expects that to drop to parity or below by 2020 – due to predicted oil price increases and efficiencies in the PlantBottle supply chain.

    Recyclability is another big win. As one of the toughest, most efficient polymers around, PET can be reused many times. That way, the plant material stays within a “continuous loop” – one up on biodegradable plastics that go to landfill and “then sit like a petroleum bottle”.

    The impacts across industry could also be profound. Coca-Cola is working with Heinz to help it produce a PlantBottle-packaged ketchup. Toyota is also said to be interested to use the technology for the seats in its cars.

    “Across all commodity plastics, this same pathway could be followed. For HDPE [High Density Polyethylene] plastic, polyethenes, films and even PVC”, says Vitters.

    Although Coca-Cola is in the process of patenting the application of the plant-based technology (known as Bio-MEG) to containers, Vitters insists that Coca-Cola ultimately intends for the technology to be open. “This is bigger than Coke”, he says magnanimously. Vitters isn’t even again arch rivals Pepsi getting a look in too. “We believe that our competition will need to be part of this journey.” Coca Cola’s sustainable packaging chief may have skipped to work this morning, but his job is still far from complete.

    Work to do

    PlantBottle is a step in the right direction, but it’s far from the final destination. The plant-based alternative only covers ethyleneglycol – around 22.5% of PET by weight. Coca-Cola has yet to develop a commercially viable plant solution for the other 77.5%, comprising the petroleum-based compound terephthalic acid.

    Vitters admits that his marketing team would have been “much happier” if the ratios were the other way around. As it is, the US beverage giant hopes to have a market-ready, plant-based alternative to terephthalic acid by 2015. A date for its integration into brand packaging is yet to be set.

    His problems don’t stop there. ‘Plant-based materials’ all sounds very wholesome and green, but not if their production requires excessive water use, pushes up food prices (by using arable land for non-food purposes) or relies on genetically-modified technologies.

    As the Coca-Cola packaging head admits: “We knew inherently that just because it’s a plant, it isn’t better for the environment by any stretch of the imagination…this programe fundamentally rests on the ability to demonstrate proven social and environmental sustainability.”.”

    For the moment, the company has turned to Brazil and the bio-ethanol extracted from the country’s vast sugar cane plantations. As a major buyer of Brazilian sugar already, Vitters says Coca-Cola has a “comfort for getting the programme started” there.. Not that the social and environmental record of Brazillian sugar is perfect. Far from it. Vitters admits there is still “a lot of growth room to meet [Coca Cola’s] sustainability criteria”. As a result, the company is working with WWF towards a sugar certification scheme in Brazil.

    In the future, Vitters conceded that it’s not sustainable to “source only from Brazillian sugar cane. If PlantBottle takes off in the way he predicts, Coca-Cola will have to look elsewhere, as well as to other plants. Excessive demand could present supply problems as well as pushing sugar prices up – something, Vitters jokes, that “wouldn’t be a good career choice” for him.

    Wisely wary

    The clever polymer chemists in Coca-Cola’s labs have identified other potential feedstocks, but the company is wary about jumping in too fast.

    “We need to be very careful about expanding use of land at a time when we think agricultural environments for feeding a growing population are going to be essential”, says Vitters, who acknowledges the need to proceed “responsibly”..

    The US drinks giant is therefore looking to second-generation technologies focused on agricultural waste, such as switch grass, pine bark, corn husks and fruit peel.

    Even then, challenges still exist. Supply is one. Finding such agricultural bi-products in commercial volumes is no easy task. Land productivity represents another issue. In many parts of the world, agricultural waste is typically returned to the soil as a natural fertiliser.

    “Disruptive” though PlantBottle may be, it falls far from enabling Vitters to fulfil his sustainable packaging brief completely. Commercialising a plant-based solution for the terephthalic acid portion of PET would help considerably. But we still have to wait for 2020 until Coca-Cola bottles of all sizes boast the 22.5% plant content.

    Nagging at his mind as well must be the fact that Coca-Cola was recently thrown out of the prestigious Dow Jones Sustainability Index. More galling still, the Index praised Pepsi as a “supersector leader”.

    There’s a silver lining, though as Dow Jones did award Coca-Cola an “uptick” for its packaging and material sourcing – another reason Vitters’ Monday shouldn’t be too blue.

Battling the bottle- from the Inside

Aspen native battles the bottle — from the inside

Max Ben-Hamoo fights bottled water — with better bottlesStewart Oksenhorn
The Aspen Times
Aspen, CO, Colorado

Aspen native Max Ben-Hamoo is the president of WorldLife Water, which has introduced water in a biodegradable bottle.Stewart Oksenhorn / The Aspen Times

ASPEN — As a kid growing up in Aspen, Max Ben-Hamoo was intensely interested in science; he went on to major in environmental science at the University of Denver. But as he got older Ben-Hamoo became more practical-minded, and after getting his bachelor’s degree, he changed directions and earned an MBA, also from the University of Denver.

“Once I realized how much more powerful business is than science, I wanted to combine my passion for the environment with some knowledge of business, and grow that,” the 25-year-old said.

Ben-Hamoo’s current career is a near-perfect reflection of the development of that sort of thinking. Where in his childhood, Ben-Hamoo disdained single-use bottles of water — “I gave my parents trouble when they got bottled water: ‘Get something you can refill,’” he said — he has adjusted his perspective and has joined the bottled-water business. But with a twist. WorldLife Water, the company which he serves as president, has introduced what Ben-Hamoo says is the first single-use water bottle to use completely biodegradable plastic. The bottles are manufactured by an Arizona company that treats the PET plastic with an additive that attracts microbes, thus speeding the decomposition of the material. (The bottles are also made without BPA, a plastic which Canada has banned as a toxic substance.)

WorldLife Water arrived on shelves two weeks ago at the Highlands Pizza Co., at Aspen Highlands. “I asked the guy there if he wanted it, and he said, ‘Yeah, looks great. I think people will love it,’” Ben-Hamoo said. “I think he understands people will want it.”

For the moment, Highlands Pizza is the only place to find WorldLife Water, but Ben-Hamoo believes retailers, especially in Colorado, will see things the way Highlands Pizza did: Customers who are attached to the convenience of bottled water will happily switch to a product that is relatively easy on the environment.

“It’s the conscious consumer we’re after, someone who will notice that biodegradable plastic is important for the future of our environment,” Ben-Hamoo said, adding that he is working on adding accounts in Aspen, where he visits frequently to see family, and Denver, where he now lives. “And Colorado is the best place for that — most people have a good understanding of that connection. We’re optimistic because we’ve gotten a great response from everyone we’ve shown it to. It’s like people were waiting for it. They feel bad about their bottled water habit, and this helps them do something about it.”

Ben-Hamoo said making a bottle biodegradable costs 70-80 percent more than a regular plastic bottle, but the added manufacturing expense results in only a slight increase in price for the customer. A 500-milliliter bottle of WorldLife, he said, will sell for between $1 and $2. The trick will be to get the big retailers who emphasize low prices to stock it.

WorldLife was founded two years ago by Kris Kalnow, a Cincinnati resident who has a house in Snowmass, and whose son, Chip, was a friend of Ben-Hamoo’s in college: “She founded the company, then quickly realized, while she wanted to keep it going, she didn’t want to be the one running it,” Ben-Hamoo said. “She knew my background and thought I’d be a good one to run it.”

Taking over the business has required some readjustment of his perspective. Now, instead of shouting out against bottled water — and seeing its use more than quadruple in his lifetime — Ben-Hamoo is on the inside, trying to make the product more environmentally palatable.

“I understand how much bottled water is out there; people are going to buy it,” he said. “If we can replace the standard market with this product, that’s better. It’s better for the earth.” (Ben-Hamoo added that the best thing that can be done with plastic bottles is to recycle them, but that, in practice, some 70 percent of bottles end up in landfills.)

Ben-Hamoo is currently the only employee of WorldLife. While he looks to line up some interns, he is handling sales, marketing, manufacturing, warehousing and accounting. And while he gains broad business experience, his curiosity about science hasn’t died. In the yard at his father’s house are buried several WorldLife bottles, so Ben-Hamoo can monitor for himself how quickly his product biodegrades.

Cheese Plastic…No, We are Serious.

Well this is new, I have heard of corn plastics…but now Cheese plastics? This is quite interesting, if they are using products that would be waste I find that  quite resourceful. Please let me know what you think about this new technology! At ENSO were all about innovative technology that will make a difference and is good for the earth.

Is Cheese the Next Sustainable Packaging Solution?

http://icommittogreen.net/reduce/is-cheese-the-next-sustainable-packaging-solution/

Cheese makes a tasty addition to any meal, but did you ever guess it could be used for packaging?

Researchers say that a biodegradable plastic made from cheese byproducts could reduce the need for synthetic packaging and keep useful materials out of the landfill.

The bioplastic made from whey protein is the result of the three-year WheyLayer project, a European Commission-funded research and development project in Spain’s Catalonia region that aims to solve a common packaging woe.

In the food industry, oxidation of oils, fats and other components can lead to unpleasant colors and flavors. So, keeping oxygen out of packaged food is essential.

SEE: 5 Absurdly Over-Packaged Foods

Plastics like PE (polyethylene) and PP (polypropylene) are excellent moisture-blockers, but to keep out oxygen, they must be coated with expensive synthetic polymers.

Most of these polymers – such as EVOH (ethylene vinyl alcohol polymer) and PVDC (polyvinylidene chloride polymer) – are petroleum-based and extremely difficult to reuse, as it is almost impossible to separate each layer for individual recycling.

Whey, the milk protein byproduct of cheese production, provides similar oxygen-blocking properties, but it’s much cheaper and more environmentally friendly.

The new packaging – developed by Barcelona-based research company IRIS – replaces synthetics with whey protein-coated plastic fibers, which could save loads of money and make packaging more readily recyclable.

After packaging is used, whey protein can be chemically or enzymatically removed, and underlying plastic can be easily recycled or reused to make new packaging.

RECYCLING MYSTERY: Bioplastics

In addition to saving money and raw materials, the new application could also keep millions of tons of whey out of European landfills. Each year, European cheese factories produce 50 million tons of whey. Some of it is reused as food additives, but almost 40 percent is thrown away.

Discarded whey collected from cheese producers can be filtered and dried to extract the pure whey protein, which can be used in several thin layers to create a plastic film for use in food packaging.

While the packaging is subject to patent applications, researchers expect it to appear in consumer products within a year. The bioplastic is expected to be used for cosmetics packaging first, and food packaging applications will follow.

The technology will likely be used in the European market at first. But many companies from around the globe showed interest in the packaging when researchers took it to the Interpack international trade fair for packaging and processes back in May.

Coke bottle Recycling Plant reopens

Embattled Coke Bottle Recycling Plant Reopens

 

http://www.environmentalleader.com/2011/08/22/embattled-coke-bottle-recycling-plant-reopens/

The troubled Coca-Cola joint-venture recycling plant in Spartanburg, S.C., is set to reopen today after being shuttered by the company in March.

But Coke is considering selling its 49 percent stake in the plant, according to the Wall Street Journal

Coke and its partner in the factory, United Resource Recovery Corp. LLC, closed the factory down earlier this year to restructure the plant and improve the quality of the plastic being produced. All 50 factory workers and most of the plant’s office staff were laid off when the factory closed.

“We are restarting the plant,” said Carlos Gutierrez, president and CEO of URRC, PlasticsNews.com reports. “We feel pretty good on the results from our retooling efforts.”

Over the last half-year the Spartanburg team has been trying to more efficiently recycle old bottles into food-grade resin and correct certain operational problems. Prior to the fix, certain lightweight bottles had a habit of flying off the production line, Plasticsnews reports.

On reopening, the plant is likely to process half the amount of bottles it was originally designed to handle, the Wall Street Journal reports.

The plant, once described as the world’s largest plastic bottle-to-bottle recycling complex, opened in 2009. It was supposed to produce 100 million pounds of recycled plastic when fully operational, or about two billion 20-ounce Coke bottles.

Heinz Ketchup joins team plant bottle?

So I saw an official Heinz ketchup plant bottle yesterday and I felt good and bad about it. Using renewable sources is awesome don’t get me wrong, but it still does not solve the problem of plastic waste in landfills and in nature! Only 5% of plastics get recycled and the rest end up as waste. While going renewable with the Heinz bottle is a great step forward, many consumers are completely oblivious to what the “plant” bottle is. A grad student from Florida conducted a survey asking random consumers questions regarding the plant bottle. 50% of the participants believed that plant bottles are biodegradable. 68% of the participants believe that PET plant based beverage bottles are better than traditional PET plastic bottles because they are biodegradable.  From the results of the survey it is clear that these average consumers are confused of the capabilities of plant based bottles.  Let me know what you think of the new bottles in the comment box below!


Heinz to Use Plant-Based Bottles Made by Coca-Cola

by Jessica Dailey, 02/24/11
Starting this summer, Heinz will be bottling its famous ketchup in more earth-friendly packaging. Yesterday, the company announced that it plans to use plant-based bottles developed by Coke — aptly named “PlantBottles” — for all of its 20 oz. ketchup bottles. The plastic bottles consist of 30 percent plant material, and are made with a Brazilian sugarcane ethanol, which results in a lower reliance on unsustainable resources as compared with traditional PET bottles.The switch is the biggest change that Heinz has introduced to their ketchup bottle since first using plastic containers in 1983. There will be no difference in shelf life, weight, or appearance, except talking labels asking, “Guess what my bottle is made of?” Heinz says that the switch to more eco-friendly bottles is a vital step in reducing the company’s greenhouse gas emissions, solid waste, water consumption and energy usage by at least 20 percent by 2015. 

When Coke first introduced PlantBottles in 2009, an initial life-cycle analysis by the Imperial College London showed that the bottle had a 12 to 19 percent reduction in carbon impact. Coca-Cola said that last year, PlantBottles eliminated the equivalent of 30,000 metric tons of CO2.

Both Coca-Cola and Heinz are working to reduce their carbon footprints. Coca-Cola recently released an updated sustainability plan, and the company plans to replace all regular plastic packaging with PlantBottles by 2020. Last October, Heinz reported that the company cut CO2 emissions by 17,000 tons since 2006 at three of its UK factories. Heinz also received an “A” grade from Green Century Capital Management and As You Sow for using BPA-free linings from some of its canned products, and creating a timeline to completely eliminate the chemical from all packaging.

Here’s hoping Heinz will create a similar timeline for replacing all plastic packaging with PlantBottles!

WHY THIS MATTERS

The negative environmental impact of plastics are widely known and understood, so here at Inhabitat, we applaud any step away from them. While PlantBottles are not a perfect solution, they still help eliminate CO2 emissions and mitigate global warming.

ACC demands positive marketing towards plastic bags


Group alleges ACC influenced comments about plastics in Calif. curricula

PLASTICS NEWS REPORT
Posted August 22, 2011

WASHINGTON (Aug. 22, 2:35 p.m. ET) — An investigative reporting team alleges that the American Chemistry Council pressured educational officials in California to revise a section of an environmental curriculum to present positive information about plastic shopping bags.

Washington-based ACC says the allegation “distorts and misrepresents” what took place during a public comment period.

The California EPA also issued a statement, saying that all revisions to the Education and Environment Initiative curriculum were made for “accuracy and educational value” and “thoroughly vetted.”

California Watch, a reporting initiative of the Center for Investigative Reporting, claims that Gerald Lieberman, a private consultant hired by California school officials, added a new section to the 11th-grade teachers’ edition textbook called “The Advantages of Plastic Shopping Bags,” with the title and some of the textbook language inserted almost verbatim from letters written by the chemistry council.

California Watch posted the report on its website on Aug. 19.

The group also alleges that Lieberman added a workbook section that asks students to list some advantages of plastic bag, and that the correct answer in the revised teachers’ edition is that “plastic shopping bags are very convenient to use. They take less energy to manufacture than paper bags, cost less to transport and can be reused.”

The claim by California Watch “distorts and misrepresents public process and the role the ACC played in it,” said Steve Russell, ACC’s vice president of plastics. “When CalEPA developed its curricula, the agency … posted an invitation [for public comment] on draft versions of the curricula.”

“We submitted comments in response to the state’s public solicitation for input,” Russell said. “The purpose of our comments was to correct factual inaccuracies and to present a more complete view of plastic bags’ environmental attributes, including their benefits, which were absent from the draft. Our comments, and those of all other stakeholders, were submitted via email and through an online form on CalEPA’s website.”

Lieberman is director of the State Education and Environment Roundtable, a nonprofit group developed by 16 state departments of education to enhance environmental education in schools. He declined to comment on his role in editing the textbook, and referred Plastics News to CalEPA, which defended the EEI curriculum.

“We stand by the integrity of the EEI Curriculum and the open and transparent process in which it was created,” said Lindsey VanLaningham, director of communications for CalEPA. “The curriculum was thoroughly vetted by all appropriate state agencies and was ultimately approved (unanimously) by the California State Board of Education.”

“Throughout the development process, the state made revisions to the curriculum based on two primary factors: (1) accuracy; and (2) educational value,” said VanLaningham. “Teacher feedback supports our belief that the EEI engages students on issues of vital importance to them and their environment, including the role of plastic in our society.”

Regardless, state Sen. Fran Pavley, D-Santa Monica, author of the 2003 legislation that requires that environmental principles and concepts be taught in the state’s public schools, plans to write ask CalEPA officials to tweak the current text to remove language that portrays plastic bags in a favorable light.

The curriculum covers science, history, social studies and the arts, and weaves in environmental principles and concepts. It is currently being tested at 19 school districts that include 140 schools and more than 14,000 students. And an additional 400 school districts have signed up to use it, according to Cal-EPA.

In its letter to CalEPA dated Aug. 14, 2009, ACC said that it felt the lesson plan on Mass Production, Marketing and Consumption in the Roaring Twenties was “extensive in its inaccuracies and bias about plastic and plastic bags.

“The ACC takes exception to the overall tone, instructional approach and the lack of solutions offered — most especially, the lack of mention of the overall solution of plastic recycling,” wrote Alyson Thomas, a senior account executive with Ogilvy Public Relations Worldwide, who submitted the letter on behalf of ACC.

“We recommend that the list of concerns related to plastic bags be balanced with a measured response regarding efforts … to promote the recycling of plastic bags,” ACC said.

Plastic bags are referred to as “litter” in the text, ACC said. “To be clear, plastic bags don’t start as litter. They can become litter through behavioral actions leading to inappropriate disposal.”

The new text incorporated that view, as it now says that plastic bags “can become litter,” instead of calling them litter as the original version.

According to California Watch, the first teachers’ edition also had been highly critical of plastic shopping bags, noting the long decomposition rate of the bags and their threat to marine life and ocean health.

That information remains in the text, but a section on the benefits of plastic bags was added, after ACC made its comments.

“To counteract what is perceived as an exclusively negative positioning of plastic bags issues, we recommend adding a section entitled “Benefits of Plastic Shopping Bags,” ACC said in its letter.

It suggested that the text point out that plastic grocery bags require 70 percent less energy to manufacture than paper ones, that lightweight plastic bags save space and fuel in transport, and that paper bags are reusable, and also can be recycled and made into new plastic bags, and plastic lumber for decking, park benches and picnic tables.

“We recommend adding text referring to the second life of plastic products, and the increase in the recycling of plastic bags,” ACC said. “Recovered plastic bags and wraps can be recycled into many products, including backyard decking, fencing, railings, shopping carts and new bags.”

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.
