PLA I am whatever I say I am

So what exactly is PLA?

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.

Brands Say Bye to Excess Plastic to Save a few Bucks.

In recent news the rumor is that a few major stores are making “significant” changes to reduce packaging. Saying Goodbye to Excess Packaging seems to be related more to high oil prices rather than true environmental concern. If companies were truly concerned about environmental factors wouldn’t they just switch to more earth friendly plastics, say ENSO? What may initially seem like a movement to lessen plastic waste has turned out to be companies just trying to save a few bucks. Target is removing plastic lids from its Archer Farms yogurts, redesigned some light bulb packages to eliminate plastic and is selling socks that are packaged with paper rather than bags. Wal-Mart has made a gallant effort to reduce their packaging by 5% between 2008-2013 by concentrating detergent to reduce size of packaging as well as making peroxide bottles from round to square and Home Depots Husky tools are switching to paper packaging. These aren’t the only companies cutting down on plastic, Seventh Generation (sustainable cleaning and personal products) has been mentioned as well. Minimizing plastic & making plastic earth friendly like ENSO is awesome but be sure to not be confused by the motive of these companies.

Major Brands Say Goodbye to Excess Packaging
by Rachel Cernansky, Boulder, Colorado on 06. 2.11

BUSINESS & POLITICS Good news, according to the New York Times: excess packaging, plastic in particular, is on the decline. Apparently more because of high oil prices than any environmental concern, but we’ll take it. The Times has examples of a few major stores making significant changes:
Target has removed the plastic lids from its Archer Farms yogurts, has redesigned packages for some light bulbs to eliminate plastic, and is selling socks held together by paper bands rather than in plastic bags.
Wal-Mart Stores, which has pledged to reduce its packaging by 5 percent between 2008 and 2013, has pushed suppliers to concentrate laundry detergent so it can be sold in smaller containers, and has made round hydrogen peroxide bottles into square ones to cut down on plastic use.
At Home Depot, Husky tools are going from clamshell to paperboard packaging, and EcoSmart LED bulbs are about to be sold in a corrugated box, rather than a larger plastic case.

And a follow-up blog post expands on a couple others:
Seventh Generation, a maker of sustainable cleaning and personal care products, began using a pressed-cardboard detergent bottle that is recyclable; an inner pouch contains the liquid detergent.
“The category potential for this is huge, from vitamin companies to pet food, juice, milk, ” said Julie Corbett, the founder of Ecologic, which makes the cartons.
Recently Wal-Mart began replacing the metal twist ties that keep dolls and other toys in their boxes with paper ties.

Now, reducing packaging is a huge step forward, but it’s not the end goal. Buying in bulk—everything from rice and coffee to shampoo using refillable containers—is always going to be the environmentally superior option.
As Planet Green has written before, “Nearly 80 million tons of waste is generated from packaging and containers annually,” and from TreeHugger: “a 10 kilogram bag of rice has 20 less bags than the equivalent in 500 gram packages. And it that one bulk bag is probably a compostable cotton sack anyhow, instead of plastic. Wasted transport fuel is reduced because much more product per container is delivered to the store.”
So yes, look for products with minimal packaging and support companies making the effort to eliminate excess, but whenever there’s a bulk aisle, shop there first.

redleaf Water Partners with ENSO to Produce Industry’s First Biodegradable & Recyclable Water Bottle Hitting Shelves Today

redleaf Water, Canada’s Ultra-Premium bottled water, is now distributing the industry’s first biodegradable and recyclable water bottle. redleaf’s BIO BOTTLES produced by Arizona-based environmental solution provider ENSO Plastics, will biodegrade naturally in aerobic and anaerobic (landfill) conditions and are #1 PET, allowing the bottles to be recycled without requiring any special handling.

Today nearly all water bottles are #1 PET, meaning they can be recycled. Some competitors have recently introduced plant-based plastic bottles. Plant-based plastic bottles can be recycled, but do not biodegrade and do nothing to reduce the quantity of bottles that end up in landfills or the environment. The BIO BOTTLE represents a significant step forward as they can biodegrade naturally or be recycled.

“redleaf’s BIO BOTTLES are a step in the right direction to further reduce the impact empty water bottles have on the environment,” said redleaf COO Dave Hillis. “When we started the company, we made a commitment to aggressively seek alternatives to reduce our impact on the environment, while still providing customers with superior drinking water. We still have work to do, but redleaf’s BIO BOTTLES represent an important step forward in our ongoing mission to provide premium Canadian water in guilt-free bottles.”

ENSO pioneered the bottles from its research facility in Arizona. The company has worked for three years to perfect a bottle that is both #1 PET recyclable and biodegradable. While the process is classified, the results have been validated by Northeast Laboratories, a testing facility certified by the FDA, EPA and the Department of Defense and ISO.

“Our bottle is designed to be placed into the existing recycle streams, but if placed into a landfill or other natural environments, depending on the natures microbial activity, these bottles will disappear within 1-15 years as opposed to 500 for normal #1 PET bottles,” stated NAME AND TITLE. “Simply put these bottles disappear the same way other organic materials do.”

Complementing the release of BIO BOTTLES, redleaf will also launch the “Disappearing Project” in Spring 2011. The project is designed to highlight how BIO BOTTLES disappear in various environmental conditions.

redleaf starts as great water from an artesian aquifer in Chilliwack, British Columbia, and is made even better through a proprietary purification and bottling process. The water’s high oxygen content and high pH of 8.3 have been known to have several health benefits for the drinker, including increased alertness, hydration and stamina – all of which are crucial to athletes and sports fans alike.

Keeping with its efforts to reduce waste and minimize its impact on the environment, redleaf’s production process has a 1:1 bottling ratio. While many competitors have a 6:1 ratio, that means competitors waste five gallons of water for every one gallon they bottle.

About redleaf water

The Truth About Biodegradable Plastics

Plastic has become an important aspect in our lives, can you imagine what kind of care you would get in a hospital if we didn’t have plastic? Some historians are saying that this age will be known as the plastic age. The next time you go to the store take a look around and see if you can find products that don’t have plastic. As important as plastic is to our lives it has also demonstrated some negative side effects and there isn’t any one perfect answer for solving plastic pollution.

MICROBES: An Invisible Universe

The book titled MICROBES An Invisible Universe by Howard Gest was one of the most informative and interesting books I have read on the world of microbes. This book is 200 pages crammed full of detailed information about the history and the function of microorganisms, also known as microbes. The author, Dr. Howard Gest is Distinguished Professor Emeritus of Microbiology and Adjunct Professor of History and Philosophy of Science at Indiana University, Bloomington. Dr. Gest is widely recognized for his research on microbial physiology and metabolism.

The Ecology of microbes to one another and their surroundings is extraordinary with respect to the diversity of chemical and physical conditions that can be tolerated. Microbes thrive in extreme environments with regards to temperatures, high concentrations of salts and sugars, relative acidity, and with or without the presence of oxygen.

Sorting out Biodegradable Plastics

There are three main categories of degradable plastics: biodegradable plastics, compostable plastics and degradable plastics. One of the biggest contributions to the confusion surrounding the subject of degradable plastics is a combination of the lack of common definitions and the loose usage of these definitions.

The ASTM International, originally known as the American Society for Testing and Materials, is a standards organization, host to committee D20.96 on Environmentally Degradable Plastics and Biobased Products. The ASTM maintains a Standard Terminology Relating to Plastics under their designation: D 883 – 08. The following are the ASTM definitions for degradable plastics:

biodegradable plastics—a degradable plastic in which the degradation results from the action of naturally-occurring micro-organisms such as bacteria, fungi, and algae.

compostable plastic—a plastic that undergoes biological degradation during composting to yield carbon dioxide, water, inorganic compounds, and biomass at a rate consistent with other known compostable materials and leaves no visually distinguishable or toxic residues.

degradable plastic—a plastic designed to undergo a significant change in its chemical structure under specific environmental conditions resulting in a loss of some properties that may vary as measured by standard test methods appropriate to the plastic and the application in a period of time that determines its classification.
