Single Use Plastic Bags: Ban or Become Biodegradable?

Whether you are well versed in the single use plastic bag debacle or if you are just hearing about it, action needs to be taken to prevent these breed of bags from causing any more damage. Many countries and cities have either banned single use plastic bags completely or have placed a tax on the plastic bag. Getting rid of these plastic bags entirely makes sense for environmental issues but whats happening in response is cross contamination, and the waste of reusable bags as well. What if we had biodegradable single use plastic bags that were also recyclable, a new start for the single use earth friendly plastic bag. ENSO has the technology to create single use biodegradable & recyclable plastic bags, Why not take advantage of this?- Megan Bentley

Countries That Have Banned Plastic Bags

We all know how terrible plastic bags are for the environment—they choke wildlife, they don’t break down in landfills (or in oceans), they add to our demand for oil, and they aren’t easy to recycle, which is the biggest reason why 90 percent of plastic bags in the U.S. are not recycled.

Yet an estimated 500 billion to 1 trillion plastic bags are used worldwide every year—380 billion of those in the U.S.—and governments have been slow-moving at best to do anything about them.

Starting January 1, 2011, single-use non-biodegradable plastic bags will be outlawed in Italy. And while plenty of questions remain about the ban’s rules and efficacy, it’s a considerable leap, seeing as how Italy uses 25% of all the plastic bags in Europe — around 25 billion a year.

Neighboring Bulgaria‘s move to impose a tax on plastic bags as of July 1, 2011, as reported in the Sophia Echo is only the latest attempt across Eastern Europe and the Middle East to discourage the use of disposable bags.

The nascent Environment Ministry in Syria – where an estimated 15 million bags are consumed each day just Damascus and the area around in the capital — has distributed fabric and paper bags to markets as part of a campaign to get people to just say “no” to plastic bags. While paper bags are not particularly environmentally friendly in their manufacture, they pose less of a danger to animals.

In the United Arab Emirates, dead camels have been found with lumps of plastic in their stomach weighing up to 30 kilograms — the equivalent of 4,000 plastic bags. According to the UAE’s Ministry of Environment and Water, which plans to ban plastic bags in the UAE by 2012, 85 percent of emirate residents “say they have heard or read about the detrimental effects of plastic bags, but fewer than half do anything about it.”

Turkey is also taking slow steps toward breaking the plastic-bag habit, though they have not been without some implementation troubles. The Kadıköy district of Istanbul was praised last year for being the first municipality in Turkey to ban plastic bags.

In California, the ban started in San Francisco in select stores; if pending legislation goes through, it could soon expand to all stores not only in the city, but in the entire state. A similar ban exists in coastal North Carolina and was recently passed in Portland.

 

In 2007, Modbury became the first town to ban the plastic bag in Britain, where 13 billion plastic bags are given away every year. If customers forget to bring their own, reports the Times Online, “a range of bags made of recycled cotton with organic and fairtrade certification will be available from £1.50 to £3.95 and cheaper paper and biodegradeable cornstarch bags will cost 5p and 10p.” Other cities have followed suit, some just a few months ago, and there are efforts to make London plastic bag-free by the time the Olympics come around in 2010. According to the Daily Mail, “Londoners use 1.6billion plastic bags a year – for an average of just 20 minutes per bag.”

Mexico City adopted a ban last summer—the second major city in the western hemisphere to do so.

India seems to be taking the lead in bans on plastic bags, although enforcement is sometimes questionable. Cities including Delhi, Mumbai, Karwar, Tirumala, Vasco, Rajasthan all have a ban on the bag.

A ban went into effect (with little notice) in Rangoon, Burma, late last year.

In neighboring China, the use of plastic bags is restricted.

Plastic bags have been banned in Bangladesh since 2002, after being found to be responsible for the 1988 and 1998 floods that submerged most of the country.

Rwanda is the country, which has had a ban on plastic bags for years, has a reputation for being one of the cleanest nations not only on the continent, but in the world.

Sydney’s Oyster Bay was the first Australian suburb to ban plastic bags. Twelve towns in Australia are now said to be plastic bag-free—an effort to cut down on the estimated 6.7 billion plastic bags used in Australia every year.

Single Use Bag Bans:Yay or Nay?

Reusable Shopping Bags Not Risk Free

The newest fad: The Reusable bag .




Reusable bags are being greatly pushed against the single use plastic bag and people seem to be latching on to the concept. It sounds like a good enough idea, and with all the design options you can really expressive yourself, but is the reusable bag really risk free? Just like many new products there may be some drawbacks that weren’t discovered before becomingso popular and “savior-esque.” The Department of Soil, Water and Environmental Science at the University of Arizona and the School of Public Health at Loma Linda University conducted a study called the Assessment of the Potential for Cross Contamination of Food Products by Reusable Shopping Bags. Now I am going to brief you on the results of this study!

So what is “Cross contamination” ?

Cross contamination occurs when disease-causing microorganisms are transferred from one food to another.

The assessment was divided into 3 Phases

1. Determine the occurrence of bacteria and bacteria of health concern in reusable shopping bags
2. Determine the potential for microbial cross-contamination in reusable shopping bags
3. Evaluate and recommend the washing/bleaching procedures necessary to decontaminate reusable shopping bags

They started off by collecting bags from consumers entering grocery stores in the San Francisco Bay area, Los Angeles and Tucson, Arizona. 84 bags total were collected, 25 from LA, 25 from San Francisco and 34 from Tucson. All but 4 of these bags were woven polypropylene (a little softer than polyester which is what a typical plastic bottle is made out of.) Each bag owner was interviewed on bag usage, storage, and cleaning procedures. (4 unused reusable bags were also purchased and tested)

 

And the Results are in…

Large numbers of bacteria were found in all but 1 bag & coliform bacteria in half.

E-Coli was identified in 12% of the bags & a wide range of enteric bacteria & pathogens.

After meat juices were added to bags & stored in car s for 2 hours, bacteria increased 10-fold.

 

 

How to Clean your bags?

Hand or machine washing was found to reduce the bacteria in bags by >99.9%. So if you clean your bag after every separate use, you should be good! (Don’t forget to think of the water and energy that adds up over time)

 

What were the bag owners habits?

Cleaned bag at home?
97% No
3% Yes

Days bags were used in a Week?
49% 1 day
22% 2 days
18% 3 days
3% 4 days
2% 5 days
3% 6 days
3% 7 days

Bag used Soley for Groceries?
70% Yes
30% No

Other uses of Bag?
57% Other Shopping
19% Clothes
10% Books
9% Snacks
5% Biking Supplies

Separate Bags for Meats & Vegetables?
75% No
25% Yes

Transport in Car?
55% Trunk
45% Backseat

Stored at home?
55% Yes
45% No

 

As you are learning these bags get pretty filthy and are brought back into stores, which is proven to be not at all sanitary. So if reusable bag users do not make the continuous effort to keep their bags clean maybe this isn’t  the cleanest solution to the single-use plastic bag problem, why not explore another option like using Earth friendly  biodegradable and recyclable plastic instead, Like ENSO?

Take a few min to read the rest of the assessment it’s definitely worth your time!
