Biodegradable Food Storage Bags
One of the most difficult things for me to reduce my use of is the plastic kitchen storage bag. I use the one gallon plastic bags mostly for storing produce. Although they do get used to store a few other items, like opened blocks of cheese, I have not found any substitute that works as well as the plastic bag to preserve the freshness of vegetables and lettuce in the refrigerator. My wife did just bring home a cloth bag that is supposed to be good for storing lettuce. I have not tried it yet, but will and see how it works.
In the spring, summer and fall I grow organic lettuce in the garden. I like the lettuce best when I harvest it just before eating, then washing, drying and putting it directly into the salad bowl. However, because several people in the family also enjoy the lettuce at different times, I typically pick a lot of it at one time. I then wash it, spin it dry and store it in the one gallon bags in the refrigerator for instant availability. I do wonder about gasses the bags might give off affecting the lettuce. But that may be worrying a bit too much.
I have thought about using plastic containers to store the lettuce. What I would really like to see is an inexpensive line of storage bags made from cellulose or some other easily biodegradable material. The key word here is "inexpensive". I was able to find several sites on-line that sell cellulose food storage bags. For the 1 gallon size, prices ranged from 16 cents to 32 cents per bag, plus shipping costs. By contrast, at our local grocery, the most expensive 1 gallon plastic bag with twist tie top was 6 cents per bag. Generic brands can be found for 3 cents each. When the plastic bag costs 3 - 6 cents and the environmentally friendly bag costs 3 to 10 times as much, which one do you think 99.99% percent of consumers will buy?
There are now many kitchen products made from biodegradable material. Some examples are the dish drying rack made from cornstarch or the cutting board made from sustainably harvested cork or bamboo. But again, the main problem with products like these is the higher cost. It is one thing to say that the higher cost is justified, but quite another to expect wide scale acceptance of a more expensive product, even if it is greener.
This may be an example of what JD at Techfun has referred to a few times in his comments. He feels efforts for change should be put forth in places where they stand the best chance of making a difference. Asking people to pay many times more for a greener food storage bag is probably not something that will meet with success.

There is a solution and much better alternative to levying, recycling and reusable canvas grocery bags for those who forgets their canvas bag at home or in the car which is called “BIOPLAST Biodegradable Plastics.”
Bioplast is a manufacturing company of BIOPLAST Branded Biodegradable Garbage Bags and Fridge Bags for the household markets and for the industry as well as Biodegradable Carrier Bags and Vegie Bags for the retail sector using their own patented unique formula of bacteria enzyme base substrate as against starch base as used by other manufacturers world over which is not as strong or durable as polymer (plastic) bags and has a cost addition of 300%-400%. Also starch based products can comprise of genetically modified crops (GM Crops) which contains PLA the substitutes can increase emissions of greenhouse gases on landfill sites and releases Methane which is 23 times more damaging than the C02 that Al and Goreites have demonized and cannot be recycled in Britain. See The Guardian reported “Corn starch based material can damage the environment”;
http://www.guardian.co.uk/environment/2008/apr/26/waste.pollution
Bioplast is the only Biodegradable technology in the world using bacteria enzyme base substrate which is 100% biodegradable within 6 months after disposal as per ASTM-D 5988-1996 and EN 13432:2000/ISO 14855 standards with the lowest cost addition of 15%-20%.
Bioplast biodegradable products are also compostable and hence enhancing the nutritive value of the remaining soil. All the ingredients of Bioplast biodegradable plastic products are food grade and non-toxic in nature therefore suitable to be in contact with food products.

Will:
You’re right about that. If people have to pay more for their green products, the green product market will definitely suffer. It’s like getting people to recycle. If they have to separate their recyclables into different bins, they simply don’t do as well as people who are allowed to commingle their trash and recyclables. It’s just human behavior. The more trouble it is - the less likely they’ll do it.
Then there’s the problem with with the supply side of green products. Everything that’s good, and good for the environment, carries a premium price tag. And it’s not always because those things are more expensive to produce. It’s because that’s what the market will bare. Go to your local car dealership and look around. The popular vehicles will always have a premium attached to the sticker price. By the time you finish paying off the premium, the savings are lost.
My proposal is that all goods and services should be affixed with a label that discloses the energy units to produce that product, or service. This would be similar to the ingredients on your typical food item. Or the warnings on a pack of smokes. With super, high speed computers that can handle multi-variant analysis this type of calculation should be possible. That way we can all compare horses to horses, cars to cars, tomatoes to tomatoes, and plastic bags to plastic bags.
Another great post, Will.

I agree with you on this that although it would be great, I doubt a large portion of the public would be willing to spend more for a greener storage bag. I think that in general people want to be more environment friendly but can be deterred by the costs of doing so. Great post as usual.

You are right Swubird and that is one of the things that bugs me about green products and organic food. That sellers see them as premium items that can be marked up for a bigger profit. It is not the whole contributor to the problem, but part of it. I am working on a post on the subject.
I wonder how “energy units” would be determined. That sort of thing is so subjective. I am also working on the whole idea of food from far away costing more in energy. It is not that simple. The distance the food travels is only a small part of determining it’s energy footprint.

Yes, Heidi - The cost of these things becomes even more of a problem as the cost of conventional food and products inflates at the current rapid rate.
Thanks to both of you for your comments!

Great post Will, I am learning so much here, right now we use tupperware for most of our storage, trying to convince my wife to spend more on storage bags would be close to impossible.

Reply to BioPlast (Comment #1):
I have been following your endless blog postings of your claims, why are you so desperate for sales? I think I know why!
Your ’so called’ Bioplast in NOT a Bioplastic, it is NOT certified as biodegradable OR compostable by any of the authorities(OK Compost, BPI, DIN CERTCO) that issue the specifications you claim, in fact the ONLY people that have ‘tested’ your products are YOU!!
Your BioPlast is made from FOSSIL FUEL based plastic, producing millions of tonnes of greenhouse gasses worldwide in manufacturing.
Plastics are proven to attract high levels of poisonous chemicals, and your BioPlast will break down into small particles that after collecting poisonous chemicals, could be taken up by the food chain and poison the eco-system, right up to us.
Your BioPlast is ADDING to greenhouse gas levels in the atmosphere, these are the cause of climate change that is linked to increasing crop failures.
The answer is NOT Mr BioPLast and his enzymes !!
The answer is plant based plastics
Plant based plastics ARE biodegradable and compostable(many compostable at home) and certified as such.
Plant based plastics REDUCE greenhouse gases in the atmosphere as the plants grow. Growing more plants for plastic would REDUCE greenhouse gases and help reverse climate change AND crop failures.
One study shows that “every pound of soy-based polymers produced instead of petroleum-based removes 2.1 pounds of carbon dioxide from the atmosphere”.
Another study shows that in manufacture, plant based plastics use 30% less energy and create just 25% of the greenhouse gases that fossil fuel plastics do. Also starch based plastics consume 2190 kg of GHG per tonne of plastic whilst the plants are growing.
If you want plant based plastic bags, made from potato and corn starch, and manufactured in the UK,(and cheaper than Tesco or Sainsburys!) head to:

Hi Paul - Why do you think the UK is ahead of the curve on so many issues like this? I have been writing about the importance of Ethical food. I am almost a lone voice in the U.S., but it is a common idea in the UK.

To look on the upside, if you are using gallon bags, you are probably cutting down on the trash from individually wrapped or small quantity food. I like the idea of plant based too. How long can billions of people dispose of plastic bags?
