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.

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.

PLA also known as  Polylactic acid or polylactide (PLA) which is a thermoplastic aliphatic polyester derived from renewable resources, such as corn starch in the United States, tapioca products (roots, chips or starch mostly in Asia) or sugarcanes (in the rest of world).

In the U.S  a majority of PLA is made with genetically modified corn (Nature Works is the largest provider of genetically modified cornstarch in the world.) According to Elizabeth Royte, in Smithsonian, “PLA may well break down into its constituent parts (carbon dioxide and water) within 3 months in a controlled composting environment, that is, an industrial composting facility heated to 140 degrees Fahrenheit and fed a steady diet of digestive microbes. But it will take far longer in a compost bin, or in a landfill packed so tightly that no light and little oxygen are available to assist in the process. Indeed, analysts estimate that a PLA bottle could take anywhere from 100 to 1,000 years to decompose in a landfill.”

Let’s get one thing straight PLA is not compostable in home compost, go ahead and try…you will be waiting a very long time and it still might not happen. PLA is ASTM 6400 which means a product can be considered compostable if a product has undergone 60% biodegradation within 180 days; the standard is 15-18 weeks at a majority of industrial compost facilities. So these industrial compost facilities, where are they? According to this site in the United States there are 422 composting facilities registered, what each facility is capable of composting I am unsure, you would have to contact the particular facility you are interested in.

So if you buy PLA products, such as PLA single use eating utensils and you do not have access to an industrial compost or you just think it will be okay to throw the fork, spoon or knife in the garbage because it seems natural enough, unfortunately it is not. That fork, spoon, or knife could take hundreds of years to decompose. If you do not plan to send your single use PLA purchases to an industrial compost, I do not see how it would be a rational investment. Not only because PLA utensils will sit in a landfill forever but because they are not very durable, they bend and break very easily and can become droopy if placed in heat. So if you’re not planning on disposing  of PLA properly what have you accomplished?  If you are one of those people who does not have access to an industrial compost or really just do not have time to think about it and prefer quality products, try purchasing biodegradable & recyclable plastic products , for example ENSO plastics.

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.

The United States is the world’s number one producer of garbage: we consume 30 percent of the planet’s resources and produce 30 percent of all its wastes, but we are just 4 percent of the global population. These are staggering numbers which I personally find incomprehensible. I’m guessing that this is one of the reasons why more people do not get involved in this issue. We have implemented over 5,000 recycling programs throughout the country which are more of a means to helping us feel better about the massive amounts of garbage being created. There is no real global plan for stewarding the earth, which is one reason we created the company ENSO Bottles, to address the plastic bottle pollution on the planet.

Chapter 2 of the book, titled “Rubbish Past” was an eye opener for me.  I was born in the 1960’s; my first encounter of the garbage problem was during the 1980’s when the major concern at that time was the filling up of our landfills.  It was believed that our cities would soon be buried in huge mountains of garbage.  What I didn’t know was that most of the methods for disposing our garbage was unregulated at the time which resulted in massive pollution of the environment.

There is a lot of concern about ocean pollution and there are a number of organizations taking a stand to address this issue.  I’ve heard and read stories about the pacific gyre and what is called the “great pacific garbage patch”, which is a floating island of garbage about the size of Texas located in the middle of the Pacific Ocean.  I never understood how so much garbage could end up in the oceans until I read that many states such as California and New York practiced ocean dumping of their garbage for many years.  This has no doubt contributed to the ocean pollution problem we face today.

Although some may believe that processing garbage is a relatively new thing, a point I took away from the book is that we have always had a problem with dealing with our garbage.  Even in the late 1800’s there were issues of polluting rivers and city streets with garbage, manure and animal carcasses.  There were major outbreaks of disease in the late 1800’s which resulted in millions of people dying and was a direct result of filth and pollution from garbage.  It is true that those in our past did not have the abundance of commodity products (and associated packaging) available to purchase however, they still dealt with and had to get rid of garbage and waste.  Archeologists have found garbage and waste processing systems from civilizations from hundreds and thousands of years ago.

The United States first sanitary landfill was constructed in 1934 on the outskirts of Fresno, California.  This marked the end to scavenging and the incineration of garbage and is the method practiced in many landfills today.  It is amazing to think that only in the last five years have we developed techniques that will allow us to process our garbage with better environmental outcomes.  Such as collecting the methane gasses which is the result of naturally occurring microbial digestion and using that gas as a source of clean and inexpensive energy.  An energy source that is not only green but is the least costly of the green energy we can produce today (solar, wind, hydro).

So what about recycling?  In the book, the author quotes a study which shows that 87% of garbage can be recycled with only 13% needing to be disposed of.  It is estimated that the energy conserved through recycling is about five times as valuable as the average cost of disposing.  As of 2000, U.S. recycling rates were surprisingly low:  54% for aluminum, 26% for glass, 40% for paper, and 5% for plastics.  Bottle bills have been shown to be a method for improving the recycling rates for plastics.  For example, the state of California claims a recycle rate for plastics of 65%.  This rate sounds really good, which it is, when it comes to beverage bottles only.  It is an example of how bottles bills can improve recycling.  However, this number does not include the hundreds of millions of plastic bottles which are used for non-beverage items such as shampoos, oils, food items, etc.  If we are truly looking at environmental solutions we would require the recycling of ALL materials that can be recycled.

Another interesting fact that I learned from Gone Tomorrow is that the United States has become the world’s largest exporter of garbage.  With the large volume of container ships coming to America to bring us our inexpensive commodities from China, India and other parts of the world where there is inexpensive labor, the ships unload their cargo and returning to their ports empty.  To fill this void, an opportunity was created to ship back our garbage (and recycled materials) very inexpensively.  So now our garbage is becoming someone else’s problem, which I’m only guessing will become our problem again sometime in the future.

One last point that was covered in the final chapter of the book is the misguided thought of creating plastics and packaging from food sources such as corn, soy and hemp.  These plastics are also called bioplastics and are being push today by the large agriculture companies such as Dow and Monsanto.  The author points out the problems with bioplastics; “they are also likely to promote monocropping and increased use of chemical fertilizers to ensure a uniform and reliable feedstock.  This would also wipe out biodiversity and pollute water and soil.  Additionally, increased demand and higher prices for crops to feed the plastics sector could impact the food supply, since those with the strongest purchasing power get the goods.”

Journalist George Monbiot argues: “Those who worry about the scale and intensity of today’s agriculture should consider what farming will look like when it is run by the oil industry.”

I recommend this book for anyone wanting to learn about the history of our garbage problem.

Enjoy,

With the domestic and world markets looking into alternative energy, it is not surprising that the use of biogas created by our landfills are emerging as an easy answer to clean energy (see bioreactor landfill). What is surprising is that this seemingly untapped resource has been available for decades, and is only now being taken serious as a mainstream source for clean energy.

With countries like England adopting a massive effort to capture and utilize methane from waste off gassing from landfills, it is another exciting development towards a green and responsible stewardship of our planet for future generations to come. Here in the US, we are looking to forge ahead in the ambitious challenge to change the way we are consuming our products and resources, and in turn how we dispose of them. There are the “old school” influences that are entrenched in “status quo”, but do not be fooled, change is here, and the scale is tipping towards a healthier way we treat our planet. We are changing mainstream things that could set a new course our children will look back and thank us for. Look at the city of San Jose, CA were this city’s vision has a goal of using 100% of the city’s electrical power from clean renewable sources.

These are exciting times where innovations like our biodegradable bottles are springing up, and alternative sources for clean power are emerging. We are excited about our involvement in this transformational process that is taking place because we can help rid a pollution problem both from a litter perspective, as well as an emission perspective. Our biodegradable plastic bottles will biodegrade to reduce plastic trash in the environment, and in the process create clean energy from the methane off gassing produced by the degrading process in a landfill. We are first and foremost an advocate of recycling; recycling should and must be the goals of everyone within the voice of our message-please choose to recycle! But with the rates of recycling as low as they have historically been in the US, we take solace in that we can still achieve a positive effect by providing clean power through our plastic PET bottle technology made with Eco-Pure.
