Newly Developed Plastic Reduces Carbon Footprint 75%

Mesa, AZ — (SBWIRE) — 06/13/2013 — ENSO Plastics™ announces their latest product; demonstrating their continued commitment to innovation and the environment with the release of ENSO RENEW™ RTP. ENSO RENEW™ RTP is a revolutionary plastic that puts the environment first with a significant reduction in carbon footprint, rapid biodegradability and the utilization of agricultural waste rather than petroleum or fossil fuels.

ENSO RENEW™ RTP provides a huge reduction in overall carbon footprint. A product’s carbon footprint is a critical factor when determining the impact on the environment. ENSO RENEW™ RTP boasts a carbon footprint over 50% less than PLA (one of the most common bio-plastics) and over 75% lower than HDPE (the plastic used to make film, milk jugs and many other items). ENSO RENEW™ RTP is made from agricultural waste that is manufactured very close to the source keeping the carbon footprint minimal. While most companies work to reduce their carbon footprint by fractions of a percent, ENSO RENEW RTP opens a whole new realm of possibilities.

ENSO RENEW™ RTP offers a unique end-of-life advantage for disposal not requiring specialized industrial composting facilities to breakdown, as ENSO RENEW™ RTP biodegrades rapidly in most natural soil and marine environments. ENSO RENEW™ RTP passes the ASTM D6400 standard for industrial composting, as well as marine degradability and home composting in as little as 10 days. Additionally, ENSO RENEW™ RTP is natural, and if accidentally consumed by wildlife will not cause harm.

ENSO RENEW™ RTP can be used as a stand-alone resin or blended with polyethylene or polypropylene. ENSO RENEW™ RTP is made from agricultural waste allowing manufacturers to take advantage of “bio-preferred” programs whether used as a stand-alone or blended.

ENSO RENEW™ RTP resin blends well with many types of PE, as well as PP, and shows good versatility in many applications; such as films, blow molded parts, and heavier injection molded parts. ENSO is currently working with leading companies in agriculture, consumer goods and other high profile applications, who recognize the unique opportunity to use plastic that is sourced sustainably, used effectively, and disposed of in a way that adds value to the ecosystem.

Between the environmental damage caused by long lasting traditional plastics and the need for alternative solutions, ENSO RENEW™ RTP will change the face of the industry and the environment.

Are you confused about recycling?

Are You Confused About What to Recycle?

When is the last time you asked yourself or someone else if something was recyclable?  It a common question and one that gets many different answers depending on what packaging or material you are asking the question about.

Most recycling programs will have information readily available to the public on what they will accept in the recycle bins.  This list however is quite small and becomes apparent that what recyclers are looking for is the cream of the crop.  If you are anything like me you put everything in the recycle bin and hope that it will motivate recyclers to start taking more material.

People in general want to do the right thing and truthfully speaking it’s a great feeling to know we are doing our part to help recycle when we do make the effort to recycle.  I suppose someday recycling will become a mainstream religion – to a very few it already is.  I often wonder what recycling would look like if people got paid for their recyclable materials?  After all for decades aluminum cans provided a source of additional funds to many and this resulted in very high recycling rates for aluminum cans.  It would sure make it a little more worth the effort to sort through and place materials in the proper bin.

The April 1st, 2013 issue of Plastics News had a great Viewpoint article by Don Loepp which addressed this very issue as a discussion point from the March Plastics Recycling Conference in New Orleans.

http://www.plasticsnews.com/article/20130321/BLOG01/130329974/plastics-recycling-are-you-still-confused#

If we are going to have recycling be a big part of the environmental solution to the growing global plastic pollution issue we are going to have to get aggressive about our recycling efforts and recyclers will need to be a stakeholder in the bigger environmental mission as much as they are with the business focus of recycling.  All materials have the potential to be recycled, let involve state and federal programs to bring innovation to the market so that recyclers can accept all materials and have markets to sell those materials.

We’d love to hear what you think?

Plastics recycling: Are you still confused?

 

Biodegradable Plastic – Compostable Not So Fast Says Stanford Daily

There was a recent press release issued by Media Juice titled “Biodegradable Plastic – Compostable Not So Fast Says Stanford Daily.”  The press release reviews a study performed by students at Stanford University regarding compostable utensils and their performance in “real world” environments.

The study points out that what the company markets as a compostable PLA material and the “Compostable” certifications that organizations (such as BPI Biodegradable Products Institute) issue on the material is not necessary a reflection of what happens in real world environments.

This brings up a great point and discussion topic and one ENSO has pushed for the past five years and that is that we are mistaken in our approach to promoting, marketing or pushing materials that will go away in any real world environment in a specific timeframe.    Even the much touted and pushed material of PLA is not a rapidly compostable as is promoted in marketing materials.  Sure, we can create test environments which are highly controlled and manipulated that will maximize biodegradation and provide results that look and sound great, but the variety that nature brings in the real world can mean a huge difference in the amount of time needed for a product to biodegrade, from months to even years. This does not change the fact of whether a product is biodegradable, just simply that to dictate exactly when it will biodegrade is a bit misleading to the consumer.

So yes – labs can show specific time frames for biodegradation, but what happens when that same material ends up in real world environments?  9 times out of 10, it doesn’t perform as promised.  So, what does this mean?  How can a material tested and certified by industry organizations such as BPI not perform when introduced into real world natural environments?  After all legislators are passing laws based on such certifications.

We would love to hear your thoughts on the subject.

Community for Biodegradable Plastics

The “Green” movement is growing at a breakneck speed. Brands are positioning themselves around their environmental initiatives in many ways, but whatever they do, addressing their use of plastic seems to be the most prevalent step in having a greener footprint on the environment. Unfortunately, there is a lot of misinformation and confusion in the marketplace about this subject. It seems like every time you turn around there is a new ban or an extreme move to address the use of plastic and it’s as if nobody really knows what to do at this point. But it’s my understanding that the advancements in new technologies are what we should really be focusing on embracing and bringing to market. I appreciate groups like the Community for Biodegradable Plastics that allow an open forum to discuss this matter. If you find yourself looking for answers to questions about biodegradable plastics and technology then this is the place where you can find them.

 

America Recycles Day

As the sun set on November 15th, 2011 the nation paused to reflect upon our struggles and achievements with recycling. This annual event, “America Recycles Day”  on November 15, comes at us every year as a chance to refocus our efforts with recycling and waste management. We have seen the percentage of plastics recycled when compared with the amount of plastics produced, continue to decline (less than 8% of all plastics produced today are recycled). With the concerns of global warming and effects of pollution, it is important to understand the impact we can have on our environment. At ENSO Plastics we encourage people to be mindful of what they can do to help, no matter how small or large. Recycling is just one of many ways in which we can help our environment and preserve nature.

Join us in taking a moment to think about what each of us can do to help our Earth. Whether it is supporting alternate energy resources like solar power, choosing biodegradable plastics, creating less waste, or considering hybrid vehicles – remember that recycling is the least we can do to sustain our future. With each of us doing what we can, America Recycles Day in 2012 will be a chance for the world to unite in celebration of success!

What did you do today to help?

 

Research shows an alternative Microalgae Plastic Innovation

Bioplastics production from microalgae

http://www.agra-net.com/portal2/isj/home.jsp?template=newsarticle&artid=20017913128&pubid=ag043

Friday October 21 2011

Poly-3-hydroxybutyrate (PHB) is a thermoplastic polyester which occurs naturally in bacteria as Ralstonia eutropha and Bacillus megaterium. Even though PHB is biodegradable and is not dependent on fossil resources, this bioplastic has been traditionally too expensive to produce to replace petroleum-based plastics. Research led by Franziska Hempel from the LOEWE-Centre Synmikro in Germany describes an alternative method of producing PHB in microalgae. Findings are reported in the open access journal Microbial Cell Factories (2011, 10:81).

PHB is synthesised in bacteria from acetyl-CoA using the enzymes ß-ketothiolase, acetoacetyl-CoA reductase and PHB synthase. The genes coding for these proteins were inserted into a diatom (Phaeodactylum tricornutum) resulting in expression of the enzymes and synthesis of PHB in cytosolic granules. After only seven days, about 10% of the dried weight of the diatoms was PHB.

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.

Better labeling for Bio plastics

This article discusses an array of trending concerns in the plastics  market, give it a read!

Report Calls for Better Labeling of Bioplastics

 

The European Commission’s DG Environment’s news service, Science for Environment Policy, has published a new report which outlines a roadmap for environmentally-friendly plastic design and the development of biodegradable plastics, as well as policy options to maximise benefits.

With such an enormous volume of plastic product sold on the world’s markets, an inevitable knock on consequence is an equally huge volume of plastics entering the waste stream, or in some cases escaping the waste stream and entering the environment, said the report.

One particular concern raised was ‘plastic soup’, which exists in the world’s oceans and seas, containing everything from large abandoned fishing nets to plastic bottles, to miniscule particles.

However, according to the report, the redesign of plastic products, both at the scale of the individual polymer and in terms of the finished product’s design, could help alleviate some of the problems associated with plastic waste. The authors claimed that thoughtful development and redesign could have an impact at all levels of the hierarchy established by the European Waste Framework Directive: prevention, re-use, recycle, recovery and disposal.

 

U.S. Government Launches Waste Electronics Strategy

The U.S. government has launched its National Strategy for Electronics Stewardship, which provides recommendations on steps the Federal government, businesses and citizens can take toward tackling the problem of used electronics. It is to target the goals identified by President Obama, of protecting human health and the environment from the potentially harmful effects of the improper handling and disposal the almost 2.5 million tons (2.27 million tonnes) of used electronics that is discarded in the U.S each year.

The announcement also included the first voluntary commitments made by Dell, Sprint and Sony to the U.S. Environmental Protection Agency’s (EPA) industry partnership, aimed at promoting the environmentally sound management of used electronics.

According to the administration, the strategy will:

  • Promote the development of more efficient and sustainable electronic products
  • Direct Federal agencies to buy, use, reuse and recycle their electronics responsibly
  • Support recycling options and systems for American consumers
  • Strengthen America’s role in the international electronics stewardship arena.

Under the strategy, the EPA and the General Services Administration (GSA) will remove products that do not comply with energy efficiency or environmental performance standards – from the information technology purchase contracts used by Federal agencies, and will ensure that all electronics used by the Federal government are reused or recycled properly.

Standards

In addition, the GSA said that it will promote the development of new environmental performance standards for categories of electronic products not covered by current standards. Several Federal agencies will work together to identify methods for tracking used electronics in Federal agencies to move toward reuse and recycling.

Key components of this strategy include the use of certified recyclers, increasing safe and effective management and handling of used electronics in the United States and working with industry in a collaborative manner to achieve that goal. As a first step in this effort, EPA Administrator Lisa P. Jackson has signed a voluntary commitment with Dell Inc. CEO Michael Dell and Sprint CEO Dan Hesse to promote a U.S. based electronics recycling market. Representatives of Sony Electronics also committed to improving the safe management of used electronics.

According to the EPA, the collaboration with industry is aimed at encouraging businesses and consumers to recycle their electronics with certified recyclers, and for electronic recyclers to become certified. There are two existing domestic third-party certification recycling entities, R2 and E-Stewards, and the electronics recycling industry is increasingly embracing these programs.

“A robust electronics recycling industry in America would create new opportunities to efficiently and profitably address a growing pollution threat,” said Jackson.

Reaction

John Shegerian, co-founder, chairman and CEO of Electronic Recyclers International (ERI) welcomed the announcement, and was encouraged to see the Federal government leading the way by establishing a policy to utilise only certified recyclers for its electronics processing, increase U.S. jobs, and reduce harm from U.S. exports of e-waste.

“As an R2 and e-Stewards certified company, ERI supports the safe handling and recycling of electronics here in the U.S. and abroad and looks forward to working with the Federal government in promoting scientific and technological developments to improve the electronics recycling process and maximise the recovery of valuable materials from discarded electronics,” he explained.

Meanwhile, Willie Cade, CEO, PC Rebuilders & Recyclers was also optimistic about the strategy’s potential to create jobs in the U.S.: “This will prove to be a very successful jobs creation and sustainability or ‘Green’ program…This is the first comprehensive sustainability strategy in our nation’s history,” he added.

Robin Wiener, president of the Institute of Scrap Recycling Industries (ISRI) commented on the Federal government’s position as the largest source of used and end-of-life electronics, and its commitment to lead by example in ensuring that it is the nation’s “most responsible” consumer of electronics.

“We are encouraged by the Obama Administration’s flat dismissal of burdensome and overreaching legislation that would ban exports and pull the rug out from under an industry that continues to create jobs and contribute to both the U.S. and global economy,” he said.

U.S. Study to convert landfill gas to hydrogen

BMW has launched the first phase of a program to validate the economic and technical feasibility of converting landfill gas into hydrogen.

BMW’s manufacturing plant in South Carolina is using hydrogen fuel cells to power nearly 100 material handling vehicles. If this is successful, follow-up phases of the project will provide infrastructure to use hydrogen to fuel the company’s entire fleet of material handling equipment.

UK: Waste to Energy Facility Given Go-Ahead

A 269,000 tonne capacity waste to energy facility has been granted planning permission near Ipswich, UK. The Environment Agency has issued the necessary draft permit for the site – effectively giving SITA UK the green light to proceed. Building work is due to start later this year and the plant is expected to be operational by December 2014.

The 25-year contract will be awarded by Suffolk County Council.

GM and ABB Demonstrate Battery Re-Use

General Motors and ABB Group have offered a potential solution to the problem of what to do with the lithium-ion battery packs used in a growing number of electric and hybrid vehicles, as those vehicles reach the end of their lives.

According to GM, the battery packs used in its Chevrolet Volt will have up to 70% of life remaining after their automotive use is exhausted. Earlier this year, GM signed a definitive agreement with ABB Group, a power and automation specialist, to identify joint research and development projects that would reuse the Volt’s battery systems.

The partners claim to have demonstrated an energy storage system that combines electric vehicle battery technology and a grid-tied electric power inverter. The companies are building a prototype that could lead to battery packs storing energy, including wind and solar energy, and feeding it back to the grid.

The system could store electricity from the grid during times of low usage to be used during periods of peak demand, saving customers and utilities money. The battery packs could also be used as back-up power sources during outages and brownouts.

Scrap Industry Worth $90 Billion to U.S. Economy

The economic and environmental impact of the scrap recycling industry in the U.S. has been highlighted in a report from the Institute of Scrap Recycling Industries (ISRI).

The study, undertaken by John Dunham and Associates and commissioned by ISRI looks at different kinds of economic activity such as jobs and exports, at the national, state and congressional district levels. According to ISRI, the economic analysis shows that the industry creates over 137,000 direct jobs, rising to more than 459,000 jobs when the wider economic impacts are taken into account. In addition, the industry generates $10.3 billion in tax revenues for governments across the U.S. as well as delivering environmental benefits.

The industry also generates significant export revenue for the U.S. The report claimed that approximately 34% of the scrap materials processed in the United States are exported to over 155 other countries for manufacture into new products. This generates nearly $30 billion in export sales, significantly helping the U.S. balance of trade.

The total economic activity generated by scrap recycling in the U.S. exceeds $90.6 billion, according to ISRI, making the industry similar in size to the nation’s forestry and fishing industries combined.

in brief

U.S. Investment in New E-Waste Facilities

Garb Oil & Power Corporation has formed a joint venture with ACG Consulting to build seven e-waste recycling facilities within the next three years, with the first planned to break ground in South Florida in March of 2012. Garb said that it intends to start work on a new e-waste recycling facility every four months thereafter, at various sites in the U.S.

Haiti: Recycling Enterprise Initiative Launched

A ‘cash for recyclables’ program has been launched in Port-au-Prince, Haiti. The social enterprise project – Ramase Lajan – which means ‘picking up money,’ will expand the collection of plastics to create permanent jobs through a network of independently owned and operated neighbourhood collection centres. The initiative has been launched by Executives Without Borders, in partnership with CSS International Holdings and Haiti Recycling.

UK Wood Waste Down as Demand Rises

Largely due to reduced activity in the construction industry, wood waste arisings in the UK have fallen by 10% since 2007, according to the Waste & Resources Action Programme’s (WRAP) recently published Wood Market Situation Report.

Arisings from the construction industry showed a 13% decrease, while arisings from the furniture and joinery sectors fell by 23% and total arising fell from 4.5 million tonnes to 4.1 million tonnes between 2007 and 2010.

However, WRAP said that an increase in the amount of wood waste being used in the biomass sector has more than doubled over the same period to 500,000 tonnes in 2010. The total amount of wood waste recycled or used in energy recovery in the UK increased to 2.3 million tonnes in 2010 – more than half of all wood waste arisings. Exported wood waste has also increased, rising to almost 200,000 tonnes in 2010.

A combination of these factors has been reflected in lower gate fees for wood recyclers since early 2009. The report claimed that while recovered wood arisings are likely to grow gradually as the economy recovers, rising demand may put further downward pressure on gate fees.

Growing demand and falling supply have led to lower gate fees Credit: WRAP

Marcus Gover, director of the Closed Loop Economy at WRAP, said: “It’s easy to put the decrease in wood waste arising down to a reduction in construction activity during the recent economic downturn, but it’s also important to note that the construction industry – one of the biggest contributors to wood waste arising – has also taken proactive steps to reduce the amount of wood they send to landfill.”

According to WRAP, the introduction of site waste management plans in April 2008 requires construction companies to plan, monitor and measure the waste generated on site, as well as industry commitments such as Halving Waste to Landfill, launched by WRAP in 2008, have also had an impact.

What percentage of methane is collected in landfills?

I recently came across an article by James Levis called Collecting landfill gas good step. This article is a reaction to a paper that Levis co-wrote with Dr. Morton Barlaz titled “Is biodegradability a Desirable Attribute for Discarded Slid Waste? Perspectives from a National Landfill Greenhouse Gas Inventory Model.” That very paper started the jumping off point for the sudden out spurt of biodegradable plastic methane emissions articles all over the web this summer.

Spinoff headlines ranging from  “Study: Biodegradable plastics can release methane” to the reckless “Biodegradable products are often worse for the planet” were at the forefront of attention.

I had reacted to such articles in a previous blog which you can read here but after reading Levis Collecting landfill gas good step article, I came across some statistics that I just had to share!

greenhouse gas emissions methane

Levis stated in the article “ The foundation of this research is a life-cycle accounting of the greenhouse gas (GHG) emissions associated with discarding waste in both national-average and sate of the art landfills”    Now here is some interesting information,

An estimated..

35% of waste is discarded in state of the art landfills which collect generated methane and use it in beneficial ways

31% of waste is left in landfills without any gas collection occurring

34% of the waste is in landfills that collect and flare the gas

lanfill

The results of the research showed that there are significant benefits to collecting and beneficially using landfill gas. Levis addressed reactions to the research, one of the most common comments being “these materials are intended to be composted, therefore the results are irrelevant.” Levis reacted to the response by stating, “But these materials are generally not composted, and most areas of the country do not have the infrastructure for source-separated compostable collection and treatment of these emerging biodegradable materials. Therefore we need to understand the effect of their disposal in a landfill.”

Another common response to the research included that the conclusions were too broad, that they neglected emerging materials like bioplastics that do not appreciably degrade in landfills. Levis responded by stating that the argument seems misguided because these types of materials are not even technically biodegradable and the study’s only mention of bio-based, non biodegradable products was to say that it would lead to green house gas emissions in a landfill.  Levis closed the article by stressing the importance of analyzing the entire life cycle of a product to know if it is better to use a conventional or biodegradable material in the production, as well as environmental and economic factors, before making your final judgment.

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.
