The Ocean’s Plastic Garbage – A Serious Environmental Hazard

Our world’s oceans are home to five growing plastic gyres – vortexes of swirling ocean currents filled with degrading plastic that pose a serious threat to marine life.

Captain Charles Moore, noted author and oceanographer, has spent years conducting ocean and coastal samplings documenting plastic fragments along the 40,000 miles of the North Pacific Ocean. Captain Moore was the first to discover the Great Pacific Garbage Patch, otherwise known as the Pacific Gyre, which lies in the northern Pacific near Hawaii. This is the largest of the known gyres – roughly 12,400 square miles in size and growing – and filled with swirling fragmented colorful plastic debris.

Plastic in the ocean takes roughly 600 years to degrade fully. Marine life like sharks, dolphins, whales and numerous species of fish mistake these colorful remnants of our castoff trash as food, often suffering starvation due to the trash being indigestible. Oddly, it’s only the colored plastic they go for, though the clear plastic is also hazardous. Plastic water bottles are regularly found tangled in ocean coral, littering the ocean floor.

Plastic garbage doesn’t just stay in the ocean. Storms periodically break gyres up, pushing waves of trash onto beaches around the globe. Hawaii’s Kamilo Beach is frequently known as Plastic Beach due to its continually being overrun with plastic trash brought in by the ocean’s waves.

This plastic comes in all sizes and forms – discarded toothbrushes, combs, cups and, of course, plastic water bottles. Plastic trash discarded in Asia and Europe makes its way to the ocean, gets caught in the Indian Ocean gyre, then gets pushed back again to litter the once pristine shoreline.

We use 2 million plastic beverage bottles every 5 minutes in the U.S.

“No one is (looking) at it as a global phenomena and at the root causes (to) try to make it stop,” said Cecilia Nord, Vice President – Floor Care Sustainability and Environmental Affairs of Swedish-based Electrolux.

“We need to make it stop,” she said.

“Only we humans make waste that Nature can’t digest,” says Moore.

ENSO Bottles realizes that what’s needed is a shift in thinking as well as action. By creating their innovative biodegradable plastic bottle with the ENSO additive, these PET-based bottles break down, rather than contribute to the world’s plastic pollution. It’s part of ENSO’s commitment “to act as environmental stewards.”

With plastic trash increasing the world over, and the devastating effect this has on marine life, it’s crucial for consumers to become responsible stewards who take on recycling to a level not seen before is needed.

Individuals doing their part can make the difference.

The Impacts of Plant-based Plastics

Corn-based and other plant-derived plastics are all the rage these days, and are marketed as the ideal way to treat our plastic addiction. They’re made from a renewable resource, lessening our dependency on fossil fuels, and they are compostable, reducing the amount of plastic waste lingering in our landfills—what could be bad about that?

Not so fast. The issue is a bit more complex than it seems on the surface, and it turns out that these plastics still have big environmental impacts, just in different ways.

Cool, My Cutlery is Compostable!

But wait. It won’t break down in my home compost pile, or in a landfill, you say? Plant-based, or Polylactic Acid Polyesters (PLA), plastics require the near-perfect conditions found in a commercial composting facility: consistent high temperatures, ideal humidity, etc. in order to break down. Very few consumers have access to these facilities; even fewer are lucky enough to have curbside composting pickup. This means that the majority of the plastics will end up in the landfill, where contrary to popular belief, they do not biodegrade.

Recycling Rewind

Well, then I can recycle it right? Wrong. PLAs are not recyclable and contaminate the recycling stream. Removing non-recyclables from the batch is a costly and time-consuming affair, and many of these costs are passed on to the consumer. Even worse, some facilities don’t bother to sort contaminated bins, and the whole load ends up in the landfill.

Oil Free, Guilt Free

But, they’re made from a renewable resource. At least I can feel good about that! Or can you? One of the strongest sellingpoints for many consumers lies in the fact that PLAs are plant-based rather than petroleum-based, and that’s a valid argument. But, consider how the majority of crops sourced to manufacture the PLA polymer are grown. Crops like corn, beets, potatoes, and other starchy plants are grown on a huge scale, are doused with tons of petro-chemicals, i.e. fertilizers, herbicides, and pesticides in order to maximize production.

Processing the plant material to make the polymer also requires energy from fossil fuels. So, unless crops grown organically, the processing plant is using clean energy from the sun or wind, the process to make PLA relies pretty heavily on petroleum.

Wanted: Farmland For Food Production

But that’s not all. Perhaps the biggest, and most controversial, impact of growing plastics is the fact that it is taking up perfectly good farmland to grow food that is not being used…for food. Scientists predict that we haven’t seen anything yet when it comes to the global food shortage, so growing plants that could be used to feed people but using them to make packaging and fuel (that’s another argument altogether) doesn’t seem like a sustainable solution.

As we continue to lose arable lands to commercial development to support the burgeoning population, cut down the rainforest to grow corn and graze cattle, it makes less and less sense to use farmland to grow plastic. Some might argue that much of our cropland is used to cultivate livestock feed to grow animals that only a small percentage of the population eats, so it’s already an inefficient system, and this is a valid point. But, it doesn’t mean that we should add insult to injury and use food as a source for plastic, it only means that the whole system needs an overhaul.

Biodegradable Plastics to the Rescue!

ENSO Bottles

So what’s an eco-conscious consumer to do? It’s not very practical (or even possible at this point) to ditch plastic altogether, so what’s the alternative?

Enter biodegradable plastics. Products made with ENSO’s leading edge technology render any conventional plastic biodegradable in a landfill setting, where most plastic ends up.

ENSO’s biodegradable bottles and other products offer a sustainable solution to the growing plastic waste problem. They disappear under natural conditions, thanks to the work of microbes that quickly and completely break them down, leaving behind only organic compounds and new soil. They’re also recyclable. To move away from dependency on petroleum to source plastic, ENSO is always working with an eye toward the future, to consider other sources like algae, and improve existing technology.

At the end of the day, the take home lesson is this: Know what you are buying, and understand the impacts of the full process of how it was made, and what happens after it’s disposed of, because green products aren’t always what they’re cracked up to be.

The Great Pacific Garbage Patch and Ocean Plastic Pollution

Marine life can mistake pieces of plastic for food.

Imagine you’re sailing the waters between Hawaii and California. The sun is at your back, the wind is in your hair, and there’s a giant pool of plastic garbage larger than the state of Texas in front of you.

Meet the Great Pacific Garbage Patch — an enormous mess of plastic and other litter swirling around in a system of rotating ocean currents called the North Pacific Gyre. Not only is the Patch incredibly damaging to the environment, but it could also be permanent unless we reform plastic production around the globe.

See, the world produces around 300 billion pounds of plastic every year, and the Clean Air Council reports that Americans throw away 2.5 million plastic bottles every hour. Only a fraction of all this plastic is recycled, with the majority ending up in landfills. Sadly, some is also dumped illegally into our oceans by various civilian, military, cruise and merchant ships, and by other means.

The problem with traditional plastics in oceans is the same problem with traditional plastics in landfills — they could last there for hundreds or thousands of years. The sun, saltwater, currents and other elements aren’t enough to break down objects like PET plastic water bottles; the plastic will only disintegrate into smaller and smaller pieces that never fully decompose into biomass and bio-gases. Marine life can mistake these small pieces of plastic for food, eat them and become poisoned. And even if the plastic isn’t ingested, it still leaches toxic chemicals that, once released, are very harmful and impossible to collect and remove.

A traditional PET plastic bottle could last for hundreds or thousands of years in the ocean.

The Great Pacific Garbage Patch is 90 percent plastic, making it the ultimate example of the negative impact plastic has on our oceans. And it and other areas like it (yes, there are more) will continue to endanger plant and animal life unless manufacturers begin producing plastics that can biodegrade into safer components.

One thing that could prove crucial to this battle is the presence of oceanic microbes like bacteria and fungi. Bottle developer ENSO Bottles has designed a form of PET plastic with organic compounds in its molecular structure — nutrients that the microbes find irresistible. These microorganisms eat away at the plastic, breaking it down into non-harmful matter in a process that typically lasts between one and five years. A traditional PET plastic bottle, on the other hand, could potentially take hundreds or thousands of years.

Where our oceans are concerned, this new biodegradable PET plastic could mean the difference between a giant floating patch of plastic the size of Texas … and cleaner oceans for generations yet to come. Which version of the future will you choose to support?

Are Bioplastics Really as Biodegradable as You Think?

Starch from corn is used to create PLA plastic.

When you hear the word “bioplastics,” you might imagine a bottle or container that easily breaks down into soil and other natural matter soon after it’s tossed — but that’s not necessarily the case.

Bioplastics are made with ingredients from renewable sources, such as potatoes and corn starch (also called PLA plastics), rather than petroleum or natural gas, and therefore, you would expect them to be biodegradable. Surprisingly, this is not always true, and there are many drawbacks to bioplastics you may not be aware of.

First, bioplastics can’t be recycled with traditional polyethylene terephthalate (PET) plastics because they contaminate the PET plastic stream. Wouldn’t it be terrible if all the plastic you’ve so diligently placed in your recycle bin for the past month winds up in a landfill because some “bioplastic” got mixed up in it? And sorting the different plastics is an option, but that takes time, accuracy and a hefty financial commitment. Second, landfill environments rarely provide a sufficient amount of heat, light and oxygen necessary for bioplastic breakdown, so bioplastics that end up there don’t decompose and instead last for hundreds, or possibly thousands, of years.

Bioplastics that are marketed as being “biodegradable” can cause a lot of confusion. The misunderstanding lies in the area between what the material is capable of (the extent and rate at which it biodegrades) and what specific conditions must be present in order for it to do so. For example, a corn starch-based plastic certainly has elements that will break down, but it needs the application of extremely high heat for this to occur, something that likely won’t be present in a landfill, nor in your compost heap in the backyard. These plastics will have to be accepted by one of the few commercial composting facilities, where all the decomposition conditions can be controlled, in order for them to successfully biodegrade.

Traditional PET and PLA bottles could last for thousands of years in a landfill.

Other drawbacks to bioplastics include abnormalities from a manufacturing and distributing standpoint. PLA plastics just don’t “behave” quite the same way that traditional plastics do. For example, bottles, utensils and other objects made of PLA plastic can only resist heat up to 110 degrees Fahrenheit (with certain resins, possibly up to 200 degrees) before their strength is compromised and they begin to melt. Additionally, bioplastics generally have weaker oxygen barriers and decreased impact resistance. All these factors can negatively impact shelf life, ease of distribution and contact with hot foods and liquids.

It would seem as though consumers have to choose either PLA plastics, which will melt, reduce product shelf life, contaminate recycling and last for centuries in a landfill, or traditional PET plastics, which work great but will last for just as long. So what do you do?

An effective solution to this problem must take the needs of manufacturers and distributors, as well as realistic landfill conditions and the processes of recycling facilities, into consideration. ENSO Bottles manufactures plastic bottles that have been specifically designed to meet those challenges. During the plastic’s creation, an additive is included which inserts organic compounds into the polymer. The result is a plastic with the same properties as traditional PET plastic (with regards to strength, heat resistance and the oxygen barrier) that can be recycled right along with PET plastic, but can also decompose in a typical anaerobic landfill environment. What’s the key? Microbes.

Check with the recycling facility to see what it does and does not accept.

With those organic compounds added into the molecular structure of the plastic, ENSO Bottles become very attractive food sources to the microbes present in landfills, and the plastic is “eaten away,” in a sense. As the microbes seek out the nutrients provided in the ENSO additive, they break down all parts of the polymer chain, including the plastic, into non-harmful bio-gases and bio-mass in a process that typically lasts between one and five years — a far shorter timeframe than the potentially hundreds or thousands of years it takes a traditional PET bottle to decompose.

So the next time you start to toss a bioplastic water bottle or packaging into a trash bin, consider where it’s probably headed: a landfill, where it will likely never experience the ideal conditions it requires to biodegrade. Contact your local collection facility instead to learn whether or not it accepts that category of plastic (referred to as #7), and better yet, consider your alternatives, such as the biodegradable ENSO Bottles.

California Sets Out to Ban the Use of the Word Biodegradable

Under the current legislation there is a bill SB 1454 that is proposing to ban the use of the word “BIODEGRADABLE” for ALL plastic products. Sounds absolutely crazy, why would any legislator agree to support this? Well, the bill is backed by the PLA industry, most specifically BPI (Biodegradable Products Institute) and Natureworks. They have proposed the legislation to prevent consumers from being able to choose other environmental solutions that make better sense. The legislation has a very compelling and sexy intent behind it which is to prevent green-washing and promote consumer awareness but what it really does is helps the PLA industry corner the market by preventing competing technologies and environmental solutions which the facts show are better than PLA.

PLA is ONLY a industrial compostable material and if used for applications such as bottles, toys, misc packaging, etc have no chance of EVER making it into a disposal environment that is needed in order to mechanically break down the plastic. When these products make it into the customary disposal methods of recycling or landfills they will wreak havoc on recycling and last forever in landfills.

Our mission is to address and help solve the plastic pollution issue in the world, this legislation will do nothing to move us closer to that goal. It will hinder innovation and prevent consumers from knowing what is in the packaging material of the products they are purchasing. We believe a better approach would be to encourage innovation, stop green-washing by requiring any claims to be backed up by scientific 3^rd party testing data using internationally recognized standards board’s testing and require brands to use definitions based on the tests performed. We believe consumers will understand what it means when companies claim biodegradable, compostable or degradable when using these terms.

On July 26 we joined a group of like minded companies and people to create the Environmental Plastic Coalition to work towards stopping this kind of legislation. We need your help to let the California legislators know that big business our voices do matter. We are creators of own reality, making choices that support our reality not ones that disarm it.

Please…. Send an email no later than FRIDAY – August 5^th to: EPC@ensobottles.com with the following: (all messages will be provided to the coalition lobbyist)

The Assembly Members need to hear from consumers on the following:

That you recognize the issue of plastic pollution and that plastic which are biodegradable will help solve the problem we now face.
Your thoughts about a system that prevents companies from promoting true green initiatives, especially when science backs up any claims.
How you feel about a bill that would ban and fine companies that are paving the way for a more ‘plastic less’ society.
Any other thoughts about the issue.

Please end with your name, the city you live in and your phone number.

We thank you for taking the time to write, solving the plastic pollution issue is a very important issue and one in which we are all involved with regardless of whether we like it or not. We need to work together in order to solve the situation that was created from the past decades. Doing your part along with people just like you we can and will make a difference and provide a better, cleaner world for the future.

Sincerely,

Are we smarter than nature?

It seems to be human nature to overcome and conquer; whether it be our neighboring countries, animals, plants, or biodegradable plastics – we seem to have instilled a belief that we as humans with our developed brains can and should have direct control over everything. From the beginning of time this desire has caused a never ending battle with nature; we manipulate it through genetic modification, we attempt to control it with toxic fertilizers, heavy machinery and pesticides. And throughout this battle we continuously marvel at our own genius – never mind the damage, pollution and unbalance we bring with it.

RUBBISH! The Archaeology of Garbage, Book Review

rubbish1 The book titled Rubbish! The Archaeology of Garbage by William Rathje and Cullen Murphy was a very interesting read. Created in 1973, the archaeology of garbage was a program primarily created as an exercise in archeology for students at the University of Arizona Tucson. The most fascinating aspect of the book is the discoveries of what our garbage tells about us as a society. It was interesting the amount of detailed behavior that can be discovered by going through trash. For example, in times of product scarcity our garbage shows that we waste more of the scarce product. Another major fact Dr. Rathje’s team discovered is that our landfills are not filling up from disposable diapers which is taking up about 1% of a landfills mass.

There have been some in the PLA (corn plastics) industry who use quotes from Dr. Rathje’s book to support an argument that composting biodegradable plastics is better for the environment than landfilling them. Their argument takes some of the data out on context by looking at the hundred year old “poor” environmental designs of landfills. The printing of “RUBBISH!” was in 1991 with most data provided in the book ending in 1988. Most of the data in the book is over 20 years old. As with many things from our past we eventually discover better and more environmentally sound solutions. Yes, it is absolutely true that traditional dry-tomb landfilling is not the best solution for dealing with our garbage. As a society we have made significant improvements to the methods we use for disposing of garbage. Since the writing of the book we have implemented hundreds of recycling programs as well as the EPA requiring methane from the anaerobic biodegradation process happening in landfills to be captured and burned or used to create clean energy. The EPA in the last 5 years has also changed laws with recirculating leachate through a landfill so to accelerate biodegradation by up to 10x.

One Step to Success

The other night I was helping my daughter with her math homework. She was frustrated and overwhelmed with the amount of problems and the difficulty level. After several hours of this, she stopped cold in her tracks. “I am not going to do this anymore, this is too hard, there are way too many problems and I don’t even know how to solve them! I might as well just quit.”

This reminds me of the many times I have felt this way myself with environmental issues –

Why do people litter?

Do I use paper, plastic or reusable bags? (I forgot my reusable bags again!)

Rain forests disappearing!

Ice caps melting!

Global warming!

Plastic water bottles

Driving my car!

The issues can sometimes seem endless and a bit overwhelming if we try to tackle everything. Sometimes I too feel like stomping my feet and giving up.

So, back to the math lesson; what happened? I covered up every math problem except one and we began to work one problem at a time. Even breaking the problems down to the individual components when a problem seemed difficult. About 30 minutes later, the lesson was complete and my eight year old stated “Once I stopped looking at the whole thing, it was easy.”

So let’s all take the advice of an eight year old and stop worrying about every environmental issue out there. Pick one simple thing and make a start – One Step to Success! (I am going to turn off the lights when I leave, how about you?)

Thanks,
Teresa M Clark
