Consumers confused by ‘bio-based’ & ‘renewable’

Very recently there was an article posted on www.PlasticsNews.com titled  Expert: Consumers confused by terms like ‘bio-based’ and ‘renewable’ . On behalf of ENSO our president Danny Clark would like to give a response to the article.


Compostable or Biodegradable?

Mr. Mojo addresses some very crucial points for companies labeling their product or packaging as compostable or biodegradable .Technology companies which provide compostable or biodegradable solutions, brand owners, manufactures, and industry organizations should make every effort to better clarify claims being made.  One major point that Mr. Mojo did not address is that these businesses and industry organizations should be providing to the public any test data supporting such claims.

The topic of greenwashing is currently a significant issue for all industries and companies trying to “go green” or provide some kind of improvement to their products and packaging.  Unfortunately we do not have clear cut protocols or processes for this.  Most of us are working towards new standards, processes and protocols that will better clarify what certain claims mean.

It is important to note for the readers that Mr. Mojo, is the Executive Director of BPI (Biodegradable Products Institute), a non-profit industry organization for compostable plastics, which certifies many products labeled compostable and as passing the ASTM D6400.  The ASTM D6400 is a pass/fail testing protocol specifically designed to validate that such materials will appropriately compost in an industrial composting environment.  The ASTM D 6400 is designed to ensure that the compostable plastics entering into industrial composting facility will not negatively impact the business aspect of that facility; breaks down within 180 days, no toxic residue, etc.

The Great Debate

There is currently a great debate about claims of compostable and biodegradable plastics, many were addressed by Mr. Mojo in the article.  One that didn’t get touched on is the customary disposal methods (or end-of-life options) of products.  Mr. Mojo may argue that compostable plastics are “more greener” or “better” for the environment but if that product is labeled as compostable but the consumer has no way to dispose of it in an industrial composting facility, or worst yet, the composting facilities won’t accept it due to contamination or wanting to keep its organic certification, what then happens to the benefit of that “compostable” material?  The issue of customary disposal methods is currently a big area of greenwashing in the market today.

Another example is found in the Aug, 2010 issue of Biocycle Magazine where a published study initiated by the Environmental Services Department and performed at the Miramar Greenery Composting Facility evaluated 105 different compostable products.  The majority of the products selected met ASTM standards (either ASTM D6400 or D6868) and many had Mr. Mojo’s industry’s organization (BPI) certification.  All of the products tested were purchased in the market.  To read the full article click:  http://ensoplastics.com/download/CompostableReport.pdf

More than half of the 105 products did not biodegrade greater then 25 percent.  Quote: “None of the compostable cutlery showed any real sign of degradation”.  The test concluded that there was no conslusive evidence from this study to suggest that all certified products will fully degrade.  In fact, 15 items that were both ASTM and BPI certified (Mr. Mojo’s industry organization) showed almost no effects of biodegradation at all”.  The result of this study led to a decision to hold off accepting any type of compostable products.

My question would be how could products that were certified as compostable by Mr. Mojo and BPI, not actually biodegrade or compost when tested in a real world environment?

Shouldn’t test results be public?

This leads me to my original point of companies providing test data to the public.  Currently, both the FTC and CA Legislation requires companies making claims such as compostable or biodegradable to provide data within 90 days.  I personally have been asking for such data for over two years now without seeing a single test report from Mr. Mojo (BPI) or the companies claiming compostability.  What I do experience, is the companies selling these BPI certified products directly to Mr. Mojo and BPI for their test data, however BPI continually informing me that the data is confidential.

To date, I have not seen an ASTM D6400 test result from BPI on any product they have certified as compostable, and given the results of the ESD study it brings up a number of questions.  The top question being, how much is Mr. Mojo contributing to the greenwashing issue we have in the market?  ENSO Bottles, provides our test data right on our website for the whole world to see – we do not hide our data and we welcome anyone to test our products, as BPI has done and validated that bottles with the ENSO biodegradable blend do actually biodegrade (as per your NSF report) .

Our industries need to provide more accurate information and education to the public.  We don’t have to agree on approach or technologies but we must provide accurate information and education.  Consumers, businesses and legislators need to be properly educated and then given correct information.  This also includes the work many of us in this group participate in regarding ASTM standards.

ENSO Plastics

Choosing the more eco-friendly plastic

All plastic is not alike.

Oxo biodegradable plastic fragments into small pieces animals mistake for food

Consumers have gotten somewhat familiar with what can or cannot be recycled. But few consumers understand what oxo biodegradable plastic is or the impact that it has on the environment.

Oxo Biodegradable Plastic (OBD) is a polyolefin plastic – a type of transparent plastic often with an oily or waxy feel to it – that’s had small catalytic amounts of metal salts and/or heavy metals added to it.

According to the Oxo-Biodegradable Plastics Association, “until the plastic has degraded, it has the same strength, impermeability, printability and other characteristics of normal plastic.”

This statement, however, is misleading. The nature of oxo biodegradable plastic is that it begins to break down almost from the point of its manufacture. This is what gives it a limited shelf life. Manufacturers have tried to combat this by adding anti-oxygen components to the plastic. This, however, weakens the polymer and ends up contaminating the recycling stream. Also these salts and metals are inorganic materials and, because they don’t break down, will remain in the soil or environment long after the material itself breaks down.

This type of plastic poses a real hazard to the environment.  Its components break down in fragments, small pieces that are often mistaken by animals for food. There’s no real scientific evidence that small microbes are breaking the plastic down to its natural elements.

ENSO bottles won't contaminiate the recycling stream or the environment

ENSO plastic bottles are more environmentally-friendly.

ENSO’s additive is comprised of organic renewable sources. The additive doesn’t react to anything in the plastic, allowing it to retain its original strength, rather than breaking down when exposed to light or oxygen as oxo biodegradable plastic does.

ENSO bottles only begin to break down when placed in a dirt or some other microbial environment that allows microbes to colonize on the plastic, utilizing it as a food source  then beginning the process of breaking it down to its basic components of biogas and biomass. ENSO bottles can also safely be integrated into the recycling stream without any worries of contaminating it.

The difference between plastics can be both simple and profound. The type you use can either have a negative impact on the environment such as with oxo biodegradable plastic or a more neutral impact as with ENSO bottles.

Which one you choose makes a difference.
