The Diaper Guide: Disposable, Cloth, Biodegradable or the G-Diaper?

I have seen many articles on the internet about all these different diaper options and it can get very confusing. Whether you are exploring your options for environmental reasons, financial, health concerns, or just want the cutest diapers for your baby you will find the unbiased information you deserve, here.

 

The Eco Side of Each Diaper

  • disposable baby diaperDisposable diapers can take 500+ years to biodegrade in a landfill. In 2-3 years 1 child can go through 8000-10000 disposable diapers.

 

 

 


  • cloth diaperCloth Diapers, depending on the company you get them from can be designed with earth friendly materials.  Cloth diapers are made to be reused and that is a good thing because it results in less waste. Of course the water and energy used to clean the diapers is a downside of cloth diapers. However there are many cloth diaper washing services specifically created to clean these diapers as efficiently as possible.

 

 

  • g diaper light blueG-Diapers were designed with the cradle to cradle concept meaning that what goes into the product will return to the eco system in a beneficial or neutral way. Waste then becomes a resource. Gdiapers have 2 options, 100% Biodegradable refills or reusable cloths. With the refills you can place them in a home compost (urine only refills), toss, or flush the biodegradable refills (break down in 50-150 days. The Gpants themselves are reusable and can last as long as you want them too, just like cloth diapers.

 

  • BiodNatures babycare biodegradable compostable diaperegradable diapers are disposable diapers made with PLA plastic. The name biodegradable makes it seem like you can throw them in the trash and they will biodegrade in a landfill but because of the lack of oxygen, this would take a very long time to occur. Biodegradable diapers are compostable in industrial compost, so if you unable to send these diapers to a industrial compost, you are only getting other benefits that the diapers may offer depending on the brand such as (lack of chemical(s) used)

 

Comparing the prices

  • Disposable diapers can run from 1,500 – 3,000 dollars depending on the brand and how long your child will wear the diapers.
  • Cloth diapers can run from 700 – 1,900+ dollars (depending on style, this is including laundry costs) (ex. 6 reusable inserts can run at $30) After doing much research, lots of people that use cloth diapers have commented about needed to use disposables for trips and at night time because of potential accidents, this is something to keep in mind in costs.
  • G-Diapers, at Target you can get refill inserts for $52/128 inserts.Also at Target you can get 6 reusable Gpants for 80 dollars. On the Gdiaper website they have all of their products listed with prices.
  • Biodegradable disposable Diapers will run you the same costs of regular disposable diapers, 1,500-3,000 dollars, depending on how long your child will wear the diapers and what brand you choose.

 

Health Effects

  • Disposable diapers are made with plastic and can contribute to diaper rash and irritation. These diapers also keep babies from feeling wetness so it can take longer for a child to understand what is happening when they are using the bathroom. It has been shown that it can take longer for children brought up on disposable diapers to be potty trained, but of course situations vary  and so do children.
  • Cloth diapers, depending on how they are washed can also cause irritation, but it is usually because of the soap that is used in cleansing. These diapers can contribute to children becoming potty-trained sooner because they are much more breathable and this allows a child feel wetness. Bumgenius is a popular stop for cloth diapers made with earth friendly materials that are less likely to irritate your childs skin.
  • Biodegradable diapers. The most popular, Natures baby care diapers are 100% chlorine free, 100% GM.
  • G-Diapers Biodegradable gRefills are made of a water-resistant breathable outer material made of all natural fiber. The inner material is an elemental chlorine free tree-farmed fluff pulp and Super Absorbing Polyacrylate, an absorbent core that keeps bottoms dry. gRefills  and 100% biodegradable. gPants are made out of cotton, with a hint of elastene for stretch. gPant pouches are made of breathable polyurethane-coated nylon, similar to what’s used in sports clothing. Pouches are breathable which means babies bottoms stay cool and diaper rash is kept at bay.gCloth inserts are made from four layers of soft microfleece and hemp/cotton. There should be little to know irritation with these diapers.

Ease of Use?

  • Disposable diapers are quick and easy. Take one off, put one on, throw the used one away and you’re done. They are good for night time wear and travel.
  • Cloth Diapers, depending on which system you use can be simple or take a few more steps. If you have a cleaning service, it takes some steps out for you, if not you need to make sure that you have a special spot for dirty cloths and that you clean them within a day or two. If you are using refills that can be thrown away/flushes/composted you just have to focus on keeping the shell of the diaper clean. If you have a system going they can work for night time and travel but it will require more attention than a single use diaper.
  • Biodegradable diapers are just like disposables, quick and easy. Take one off, put one on, throw the used one away and you’re done. They are good for night time wear and travel.
  • G-diapers , if you are using disposable refills are quite easy, same number of steps as using a disposable. If the gpant gets wet of course you will need to place it in a bin to be cleaned and use a fresh one. If you are using the reusable cloths you will need to make sure they are cleaned within a day or two.If you hiring a cleaning service for cloths gdiapers are very simple, if you use refills, they are still very simple. These diapers have a lot of leak free structure so they are ok for night time wear and traveling.

Labeling is a part of Education

 

 

With all of the amazing efforts to create products that push toward a more green disposal process consumers are being left holding the product and feeling a little unsure  just how to dispose of it. This is due to a lack of understanding terminology and a lack of           clear labeling on the products. The first product that comes to mind when I think of this topic is Sun Chips. According to the Sun Chips website they have the first 100% compostable chip bag. There website includes a section called “Composting 101” that explains the process of disposal that can be found here Compostable Packaging 101 – Sun Chips

This is great but what do the actual bags tell you to do? On the back of the Sun Chips bag it states that in about 13 weeks there will be a “breakdown into compost in a hot, active home or industrial compost pile”  it then states “Don’t compost yet? Learn more about our bag, what it’s made of and how to compost effectively at www.SunChips.com”  The bag is vague and pushes consumers to visit their website to actually learn how to dispose of it. There’s nothing wrong with this but if you are driving in your car on a road trip you may find it tempting to just chunk the bag in the garbage rather than holding on to it until you get home so you can visit the website and learn how to compost it. If the labeling on the back of the bag just gave the instructions I think consumers would see that the whole process is so simple.

By making consumers go visit your website it seems like there is too much information to include on the bag and that can seem daunting to a consumer. We live in a world where people want instant information at their fingertips. Why not just include the instructions on the labeling of the bag?  This blog is not picking on Sun Chips but simply just recognizing that if companies were to label products more clearly we as consumers would know just how to dispose of the products instead of just giving up because we do not understand.

 

Here are some key terms you should know to help you better understand all those labels out there.

 

Industrial composting refers to large scale composting systems that are being used more commonly as an alternative to landfills. Here is a short video that will show you an example industrial composting. More info here

Home composting refers to a process that can be done in most backyards in a homemade or manufactured compost bin or even an open pile. The bins should include 4 ingredients: nitrogen, carbon, water and air.  For more details on home composting visit this site More info here

Biodegradation refers to when plastic or any other material degrades over a period of time.  Biodegradation can occur in either aerobic (with oxygen) or anaerobic (without oxygen) environments.

ENSO plastics do not begin to biodegrade until the plastic is placed into a highly microbial environment i.e. landfill.  Once placed in a microbial environment the ENSO additive has a microbial attractant to help facilitate microbial colonization. Once microbes have colonized on the plastic they digest the additive which causes the production of specific enzymes within the microbes. These enzymes are the key to plastic biodegradation. The microbes break down the resulting material through atomic reorganization to use some of the atoms as energy and leaves behind either methane (anaerobic) or CO2 (aerobic) and inert humus.  Having the plastic biodegrade from microbial digestion is the natural process of everything and does not leave behind any polymer residue or toxic materials.

Degradation can be initiated by oxygen, ultra violet light or heat.  In many cases these products begin to degrade the moment they are manufactured which leads to a shortened useful life. When something is degradable it means the plastic is only broken down or fragments into smaller and smaller pieces and will never completely disappear.

 

 

 

 

 

 

 

 

 

Does Biodegradable Equal Less Recycling?

 

Let’s say that someone hands you two water bottles. One of the bottles is made with biodegradable plastics and the other is not. Which one do you feel is the more environmentally friendly product? You’re probably thinking the biodegradable plastic bottle, right? A majority of people would agree with you including myself. Now, because the bottle is biodegradable do you think that consumers will feel less guilty littering and feel less motivated to recycle? This is something to think about but lets take a look at some statistics. After surveying over 350 people, more than 90% stated that if a plastic bottle was labeled biodegradable that they would not feel comfortable littering the bottle on the ground. Another thing to take into consideration is that 75% of the people that took the survey also believed that it could range from less than a year to 25 years for a biodegradable bottle to biodegrade. It seems that many of these people are aware that biodegrading is not an instant process, whether they have researched the facts or are just going off of what they think. Did you know that in a perfect anaerobic environment ENSO plastics will fully biodegrade in 250 days but in a microbial environment like a landfill it may take longer.

Now back to a question I asked earlier, because the bottle is biodegradable do you think that consumers will feel less guilty littering and feel less motivated to recycle? Think about what choice you would make and then ask yourself why you would take that action.

What it comes down to is that by labeling something biodegradable it doesn’t mean it will result in less recycling or more littering. We all need to be aware of the facts so our choices will actually make a difference.

Coke joint venture shuts down PET plant

 

SPARTANBURG, S.C. (Updated April 22, 10:40 a.m. ET) — The joint-venture PET recycling plant that Coca-Cola Co. opened with great fanfare two years ago in Spartanburg, S.C., has stopped making food-grade recycled PET, but hopes to resume that process sometime this summer.

Neither Coke nor United Resource Recovery Corp. LLC ever made any official announcement about the shutdown of those operations at their joint venture plant, NURRC LLC. Only after Plastics News broke the story April 18 that 50 factory workers were laid off in early March, and virtually the entire office staff was laid off two weeks ago did Coke issue a statement to PN that operations had been “curtailed.”

In an email response, the Coca-Cola executive only said that Coke was restructuring the Spartanburg joint venture, which was designed to be the largest bottle-to-bottle PET recycling plant globally. Vitters is general manager of the Plant Bottle packaging platform for Coca-Cola. He was previously director of sustainable packaging.

In a separate statement sent specifically to Plastics News, the Atlanta-based company said “we cannot discuss the specifics of Coca-Cola’s business dealing with NURRC. The joint venture, however, needs to be restructured in light of further business conditions.”

Without providing additional detail, the statement said that “plans are in place to continue to operate” the Spartanburg facility. Similarly, Vitters said “we intend to continue working with processing facilities, throughout the U.S., including NURCC, to supply [recycled] PET to our system.”

There was no immediate response from URRC to inquiries from Plastics News.

Sources also said that NURRC is remiss in its payments to its brokers and materials recovery facilities, and that at least one lawsuit has been filed by a supplier of PET bottles seeking payment. They also said that several NURRC staff employees have been actively inquiring about job possibilities at other plastic recyclers.

In addition, John Burgess, president of Coca-Cola Recycling, has been placed on indefinite leave, sources said. But Vitters said that personnel action was not related to the Spartanburg recycling operation.

The Spartanburg plant had been ballyhooed as the shining star that would enable Coke to achieve its goal of incorporating 10 percent recycled content in its PET bottles by last year and 25 percent by 2015.

But Coke did not meet that goal of 10 percent recycled content for its PET bottles in 2010, and sources said that only about 1 million pounds of recycled PET from the NURRC Spartanburg plant — which is only a fraction of the plant’s nameplate capacity of 56 million pounds — actually wound up back in PET bottles.

“I have heard for a long time that the plant could not meet the specifications for bottles,” said one source.

“Coca-Cola remains committed to our goals of sourcing 25 percent of our PET plastic from recycled and/or renewable material by 2015, and to recover 50 percent of the equivalent bottles and cans used by 2015,” said the company in the statement it emailed to Plastics News.

The “recycled and/or renewable materials” is significant, because Coke has been making a big push in recent months in renewable materials. The company has said it expects to convert all of its plastics packaging to PlantBottle materials — PET made from sugar-cane ethanol — by 2020.

Sources said the Spartanburg plant had undergone three engineering redesigns in an effort to make its process profitable.

“The technology might have been the best several years ago, but it doesn’t work as well as other technologies with the newer, lightweight bottles,” one source said.

In its emailed statement to Plastics News, Coca-Cola’s only comment relative to the technology at the plant was that “new equipment” was being installed.

“We started this joint venture with URRC to test out technology that would increase access to valuable recycled content for use back into our bottles. That desire has not changed.”

The plant never added the second line that it had planned to bring online by the end of 2009 or early 2010, and it struggled to achieve its nameplate capacity of 56 million pounds — 44 million pounds of clear material and 12 million pounds of green material.

Coke’s initial investment in the plant was estimated to be between $45 million and $50 million.

One source said the majority of the plant’s output ended up in lower-end fiber and strapping. The source said one Coke bottling plant had two silos worth of output from the plant that was unusable for bottles.

“In the long-run, it has to work in the marketplace,” said one source. “Its failure is kind of a black eye for Coke.”

The NURRC plant closing is a short-term boost to other recyclers, as it makes more material available in a tight market to PET recyclers such as Clear Path Recycling, Custom Polymers PET, Wellman, Pure Tech Plastics, Phoenix Technologies, Carbonlite Industries, and others.

“That is good news,” for those companies, the source said. It also helped PET bale prices — which had been rising — stabilize in March.

Before the NURRC plant closing, PET reclamation in the U.S. was expected to reach 1.88 billion pounds sometime in 2011. That’s more than double the 847 million-pound PET reclamation capacity at the end of 2008. And tight supplies had already forced the cancellation of three capacity expansions this year, including a second 120 million-pound-per-year line planned by Clear Path.

Sources said the NURRC plant closing was triggered by a request in February for $15 million from Coke to fund the next phase of expansion. NURRC wanted to add a second recycling line to increase production.

When Coke declined to make that investment, that left NURRC without money to continue operations, sources said.

URRC, which owns the joint-venture plant, is looking for investors, sources said. However, other sources speculated that Coke may buy the plant at a greatly reduced price.

One source told Plastics News that Coca-Cola Recycling employees were told in an internal memo that the Coca-Cola Recycling was going to take over NURRC.

“Everything about this plant from Coke has been totally greenwash nonsense from top-to-bottom from Day One,” said one source.

Coca-Cola still has PET recycling plants in Mexico, France, Austria, Switzerland and the Philippines.

This Valentine’s Day Give Your Sweetheart a redleaf

This Valentine’s Day, instead of chocolate and diamonds, give your sweethearts something they’ll really love: redleaf water in their new BIO BOTTLE. The BIO BOTTLE is a first of its kind: a recyclable and biodegradable bottle developed by ENSO Bottles.

“We’re thrilled to have redleaf water using ENSO biodegradable bottles. Working together with redleaf is going to have a huge impact on helping the environment. It is only natural that a genuine display of commitment and corporate responsibility has magnetized the redleaf brand”

Earth-conscious consumers have long embraced redleaf’s unique high oxygen, mineral rich water to quench thirst and refresh their body. redleaf‘s passion to improve the environment is reflected in the design of its facility that boasts no water waste during bottling.

“redleaf’s mission is to provide our Ultra-Premium Canadian water in guilt-free BIO BOTTLES – and now that has become a reality!” said redleaf COO Dave Hillis. By embracing biodegradable technology from ENSO, redleaf is giving consumers the opportunity to take responsibility for a healthier earth.

redleaf’s BIO BOTTLE is a step in the right direction to further reduce the impact that empty water bottles have on the environment. Now consumers can recycle like they always have, but if an empty BIO BOTTLE ends up in a landfill it will biodegrade naturally, like any other organic matter.

“We’re thrilled to have redleaf water using ENSO biodegradable bottles. Working together with redleaf is going to have a huge impact on helping the environment. It is only natural that a genuine display of commitment and corporate responsibility has magnetized the redleaf brand,” said Danny Clark, President of ENSO.

redleaf is sweeping across the Mountain West Region of the U.S. and can be found in major grocery stores such as Fry’s, Albertsons, and Bashas’ as well as several prestigious American athletic events, including Los Angeles Angels and Oakland Athletics Spring Training.

Do you have blue barrel anxiety?

‘m suffering from “Blue Barrel Anxiety,” and so are a lot of other people around the country. What is BBA you ask? Think of it like this. You are cleaning up after a family picnic, the table is covered with paper plates, an empty pickle jar, a plastic mustard container and lots of other things made from plastic and paper…lots of other things. If you have ever wondered, does this go in the trash or recycle bin, then you have experienced what millions of us have, the dreaded BBA, “Blue Barrel Anxiety.”

I was suffering so badly from BBA that I didn’t know what to toss into my blue bin…Blue Barrrel AnxietyI’d even gotten a letter from my trash collection company warning me that I was about to lose my Blue Barrel privileges. Don’t be disheartened, I’ve discovered the cure for BBA. It turns out that by educating oneself, BBA can be reduced and more importantly for me, no more letters.

I set up a tour to my local recycling center. WARNING and DISCLAIMER: Prepare yourself, seeing firsthand what becomes of the things you put into your recycle bin may shock you. Perhaps you might consider taking a friend or the entire family for moral support. You’re going to need it.

How did my tour go? Well it wasn’t what I expected. The facility I went to gave the tour from an enclosed area where we observed the process through glass windows. We didn’t hear much of the noise or enjoy the smells. The room we were in was equipped with a room deodorizer that periodically shot a mist on the air which covered up any noxious odors. I wondered what was in the deodorizer and why suddenly I was feeling a lot of love for all those recyclers working the picking line, hmmmmm.

Anyway… the thing that got most my attention was the amount of “recycled” items that aren’t recycled. A lot of the stuff…most of the stuff, we put into our recycle bins isn’t recycled, it is disposed of in the landfill. I was a little taken aback and somewhat hurt that all the plastic, cans, and containers that I had rinsed and carefully placed into my recycle bin were being treated like garbage and I was wondering why?

The tour guide must have seen the questions in my eyes…I heard the mister spray again and the love return. The tour guide went on to explain that recycling, while being good for the environment is in the final analysis a business activity. Items we toss that don’t have market value are stored or sent on to the landfill. Most of what I saw being saved was plastic containers and cardboard, so I assumed most of the unwanted material became garbage. The tour guide went on to say, “When something has value or there is a market for a recycled item it is captured, bundled and sold.” I pointed out a bin filled with glass bottles and I asked our tour guide why they weren’t recycled? His answer was that it’s cheaper to make new glass than recycle. I was becoming educated and my BBA was starting to ease. I learned that recycling is about money, at least here in the U.S. it is, and until there is a demand for recycled glass or the price of virgin glass goes up….it’s off to garbage land with used glass.

Reclycing BinsIt turns out that U.S. Recyclers are very picky about what they want and are only willing to spend the time, labor and money on items that can easily and quickly be captured from the recycle stream. In other countries recycling has taken on a whole new meaning. I recently read about another country where even a tennis shoe is dismantled for the metal, leather and rubber. Is that cost effective? Probably not, but those countries are coming closer to a sustainable life style than we are. The tour was an eye opener and it got me to questioning if there was any real value to recycling here in the U.S., or was it all just a way to make money, appearing to be environmental?

Organizations that promote and support recycling here in the U.S. need to do more toward developing new markets for the goods we now toss into our landfills. Most of their efforts are spent on maintaining the status quo of recycling and they don’t take kindly to anyone rocking the garbage boat.

Public awareness and acceptance for environmental programs continues to grow and recycling organizations need to embrace environmentalism and its potential benefits. The U.S. needs to follow the lead of countries that have successful recycling programs, programs that are reclaiming up to 75% of waste materials. Recyclers need to get away from the idea that recycling is just a for-profit business and begin to look at recycling as the anchor for all our environmental programs.

Use, reuse, recycle and reclaiming are all about sustainability; it should become the mantra of all businesses and consumers. We need to rethink how our products and packaging are designed, used and when the life of a product is over how the resource is reclaimed. Sustainability is important for our future and it’s the only way we will be able to ensure a healthy planet and that resources will be available for future generations.

BPI Releases Biodegradation Test Results of Aquamantra Bottles

On Feb 01, 2011 the Biodegradable Products Institute released its biodegradation test results of Aquamantra’s ENSO Biodegradable PET Bottle. BPI which is an industry organization for compostable plastics had the biodegradation tests performed by the highly recognized NSF laboratory.Lab Worker - Testing biodegradation

NSF conducted the biodegradation test of Aquamantra’s biodegradable PET bottle, using ASTM D 5511 Standard Test Method. The ASTM D5511 is a standard test method for determining anaerobic biodegradation of plastic materials under high-solids anaerobic-digestion conditions”.

This ASTM Test Method calculates the amount of carbon dioxide and methane produced during the testing period. The cumulative amount of carbon dioxide and methane evolved from each vessel is calculated and compared to the amount of CO2 and CH4 evolved from blank specimens to determine percent degradation.

After 60 days, the Aquamantra ENSO bottle achieved an overall biodegradation total of 4.47% or 10% of the positive control. As part of the normal biodegradation process with this test method, the biodegradation process drops significantly for both the cellulose and plastic material, shown by the gas generation curve plateauing. Using the test results from this test of 4.47% biodegradation over 60 days and providing an environment with a steady innoculum the test material would fully biodegrade in approximately 3.7 years.

The Aquamantra ENSO bottle utilizes less than half of a percent of active biodegradable ingredients. In other words, the bottle BPI purchased in the market and used for testing was 99.5% PET and .05% biodegradable additive material. Comparing the biodegradation of the Polyethylene material (.37%) the results clearly indicate that biodegradation by microbial assimilation of the ENSO bottle is happening at a rate 8x more than the organic additive within the bottle. By moving the ENSO plastic into a new batch of innoculum biodegradation would continue to happen. There is no indication or scientific reason to imply otherwise.

There were a few notes to keep in mind about this test. The key to performing an effective ASTM D 5511 is in the proper preparation of the innoculum. Many labs are challenged when it comes to preparing a functional innoculum for this test. This is evident when the biodegradation rate of the cellulose material does not reach 70%. In the case of this particular test the cellulose material reached a maximum of 44.31%. Cellulose is a basic material that is normally biodegraded very rapidly and is used as a baseline to validate biodegradation. As stated by NSF, because there was clear biodegradation of the cellulose the the test results are acceptable even though the ASTM D 5511 required minimum of 70% was not obtained.

As a final point; with beginning with a healthy innoculum, biodegradation would have been improved for both the cellulose and ENSO biodegradable bottle; thus resulting in an improved biodegradation timeframe. We recognize that the slower performing innoculum may in someways perform closer to a true landfill environment.
