So we're all getting pretty darned familiar with the arguments for and against biofuels. But what about bioplastics? Since we can, theoretically, do anything with corn that we can do with petroleum, wouldn't it be better to do it with corn?
Well, not necessarily. BioPlastics are a mixed bag, and considerably more complicated than biofuels. Mostly, this is because there are about two dozen different ways to create bioplastic, and every one has different properties and capabilities.
- Why make stuff out of it when you can eat it? There are lots of hungry people in the world, and it seems a little odd to be making disposable cups out of the stuff when it could be being eaten. Though bioplastic definitely isn't causing an increase in the price of food, it's not impossible to imagine it.
- You can't always recycle it. Because bioplastics come in dozens of varieties, there's no way to make sure you're getting the right chemicals in the recycling vat. And, in general, the solution is compost instead of re-entering the supply stream.
- It could make plastic recycling impossible. Even worse than not being recyclable itself, if it creeps into the recycling stream (which is likely, since it doesn't look any different) it can introduce new chemicals that make the final recycled product weaker or even unusable.
- Compostable doesn't mean compostable. If you toss a bioplastic fork into your compost and assume it'll be dirt in a few months, you'll be sorely disappointed. While bioplastic is (sometimes) compostable, it requires high intensity, high heat commercial composting.
- It's never made from organic corn, and generally made from genetically modified corn. And while EcoGeek doesn't have a problem with genetic modification, many other environmentally aware people do.
- It makes low quality plastic. Instead of solving the problem of the disposable society, bio-plastics generally can only be made into disposable items. They're having problems even making transparent bioplastic that's strong enough to hold water for a few months.
- It's good marketing, but bad honesty. It's very easy to have bioplastic cups or bags or forks. But it's very difficult to figure out what that means. Because there are so many different types of bioplastic, you never really know what you're getting into. Maybe it's compostable, maybe it's not. Maybe it's recyclable, maybe it's not.
- What's wrong with storing carbon in landfills? Plastic has gotten a bad rap, for poisoning babies and strangling sea lions. But if it is used properly and ends up in the landfill, I don't see what the problem is. Creating durable products with petroleum is certainly much preferred to burning it. And while plastics factories are big polluters, bio plastics factories though better, don't get us clean either.
None of that is to say that bioplastics might not reign supreme some day, they certainly have advantages as well. They're infinitely producible and safer to burn. But until a durable, recyclable and cheap option starts to win this crazy format war, I'm staying away.

I agree that all the points are problems, except 1 and 5.
Also, I disagree with the first comment, because something has potential, it doesn't mean we should ignore all its negative qualities (I hold the same view with regards to CFLs [don't get me started] and some hybrid cars [ones creating more pollution in manufacturing than they save on the road] as well).
Also, rather than wasting my time/energy/money on something that 'could potentially' be good, but is currently bad, I'd rather spend it on something that actually is good.
written by Hank, September 03, 2008
@Clinch: I believe 1 and 5 are the weakest points as well. Funny...since they're likely to cause the most alarm. But as for spending money on something that "could potentially" be good not being effective, I completely disagree. We should be putting as many eggs as possible into as many baskets as possible.
Generally, if we're spending money on them it's because they "could potentially" be better than any other solution.

bioplastics don't have to be made of foodstuff. they can also be made of cellulose. these new technologies often use food as a base because it's easiest and cheapest. once initial hurdles are overcome, it's likely that they will use non-foodstuffs as their prime ingredients.
a significant advantage of bioplastics is that they are at least carbon-neutral and, at best, can sequester carbon. petro-plastics are, at best, carbon-neutral.

And recycled plastic isn't thrown in a "vat of chemicals". There are techniques coming in to recycling industries that can seperate all forms of lastic - improving both industries output.
Low quality plastic? PLA actually has better sealing qualities than most plastics. What research can you show to back this up?
While there are issues with bioplastics - there are issues with recycling to. I think consumers should campaign to their supermarkets if they have an issue with their packaging. Blaming an industry in its entirety won't help.

2.bioplastics arent intended to by recycled, unless you count composting as recycling.
3.less than 2% of plastic bags get recycled. PE is by far a bigger corrupter of composting efforts than bioplastic is of recycling of PE.
4. astm6400 (USA) standard clearly defines what is compostable.
5.organic and gmo are two different subjects
6. Clearly you havent seen PLA bottles?
7.astm6400!!
8.storing carbon in landfills?? anerobic decomposition (no oxy) creates methane (bad greenhouse gas) removing organics from landfills for biogas and composting takes organic waste back to nature properly.

There is also a vast amount of plastic finding its way into the sea. What happens is that it gets broken down into smaller particles and can be eaten by small creatures and find its way up the food chain. Something like 20% of a handful of sand at the waterline at southern british beaches has been found to be plastic. I don't think the full impact of this problem has yet been realised.

India is self-sufficient in its food production, but a third of its people is hungry. And I don't think they waste it in bioplastics or biofuel.
I see no point in burning edible material (or using land to produce fuel when it could be used to produce food), but I think bioplastics could be a sustainable product.

1. there is no food crisis, and those who do go hungry are farmers, who would stand to benefit by alternative markets that bring in incomes. This has been well-established by agronomists and development scientists alike: bioenergy, biofuels and bioplastics can help end hunger, by providing farmers with new opportunities.
You obviously are not aware of the fact that 75% of the world's hungry people are farmers, who go hungry because of a lack of investments and income, not because of a lack of food.
2. bioplastics can be made any starch or sugar source, even from grass and other cellulosic feedstock. So stop obsessing about corn. And please stop generalising: corn bioplastics are not "bioplastics" in general.
So please change the title of your article.
3. composting is far more sensible than recycling. Recycling materials is the worst option of all possible carbon- and energy-management options. Recycling is not part of the 'cradle to cradle' idea; bioplastics that are food for new crops, are.
4. petro-plastics kill the environment and life. Bioplastics dont.
5. letting petro-plastics decay in landfill means throwing away petroleum. Bioplastics are a closed cycle of biomaterials that can be perpetually renewed.
Djee, amateurs like the person who writes this blog should really know when they are totally incompetent to talk about certain issues.

Bioplastics can come from a variety of sources, polylactic acid is a renewable fermentation product, you don't recycle it, it decomposes in landfills (not composts), aka, like chemically treated paper. Other polymers are made either using byproducts of the food process or chemicals like starch, (80% of starch is not used in food but industrial applications). I cannot think of one biopolymer that is recycled, but all will process in the recycling stream based on glass transition and other physical parameters, not chemistry. Lastly, the quality is inferior to most rigid polymers, however it is more than suitable for 70% of plastic applications.
Seriously, were you trying to stir controversy or are you really that arrogantly clueless.

First off, I live in a community with industrial composting, and so many businesses are buying compostable ware (corn, bagasse, cellulose, etc.) and composting it with food waste. This is great and diverting lots of waste from the landfill.
Second, there may be bioplastics out there that are not compostable or that are made from GMO corn, but the primary sales source for compostable ware in our area is Eco Products and the last time I researched what they sold the corn products clearly stated that they were not made from GMO corn and that they were indeed compostable.
Thirdly, I have an Earth Machine composter and I have put in compostable corn cups, bagasse plates, egg cartons, corn straws, and corn forks and although it takes them a while -- in 4 to 6 months they do compost even in my home set-up.
And lastly, our local recycling group EcoCycle which is staffed by some hard core greenies even sells compostable ware for Zero Waste events. Maybe they are pulling the wool over my eyes, but these folks live for the environment, so I have a hard time believing they'd support compostable ware if it was as bad as you claim it to be. Perhaps you could contact a staff member at Eco Cycle and present them with your above ideas. Talk it over and then get back to us with your final analysis.
Thanks for not just believing something is green because that is how it is marketed, at the same time, don't ditch compostables just yet.

Bioplastics aren't perfect. Hank's point being. What he did in fact do was make us all discuss and think about what we are being told.
In my Canadian city where we already have governemnt funded programs set up for recycling AND composting and everyone is legally required to do both- bioplastics have absolutely NO place. No matter that they don't use petroleum, that they are renewable, that they "can" be composted- they aren't. Because the reality is that the system isn't ready to process bioplastics realistically.
The result: everyday people are being sucked into purchasing drinks/bags/products made of bioplastics (or containers) and these products end up in the landfill where the consumer is led to believe that it was the "greener" choice.
An analytical question would be: Should Bioplastics be the all encompassing answer that the media would have us believe?
Also- there is world hunger, and anyone who claims otherwise is obviously privelidged. Doesn't the US have one of the highest poverty rates for economical status?? Canada is up there too.

If you knew anything about biofuels or bioplastics you'd realize EVERYTHING is moving to algae oil.
Algae oil doesn't need fresh waster, doesn't use crop land, and uses 3 times the CO2 that land based crops do.
We can meet domestic oil need with only a few million of America's 2.3 billion acres and be completely energy independent.
The question is.. Why don't more people know ?
Why doesn't Obama or even the money hungry GOP realize how much money there is to be made by taking this market by storm.
We've had studies showing the viability of algae oil all the way back to 1970's. With today's technology and a high density design we can produce 100 times more oil per acre than soy, corn or even palm.
How do you guys not already know this stuff ? You called eco-geeks.
What do you do with your time other than read about renewable energy and such ?
Everything is pointing to algae oil as a real industry not a government experiment. They can even produce gasoline from the oil now, not just diesel. I believe they have a jet engine that runs on it as well.
HELLO EARTH TO PEOPLE..... ALGAE IS AN ANCIENT AND REFINED ORGANISM THAT IS MADE UP AS MUCH AS 50% OIL.
What more of a solution do you need? Do you need the algae to grow little hoses and pumps too ?

1. The relevant question would be lifecycle greenhouse gas emissions including the manufacturing of the plastic fork. Stating that you can defer CO2 emissions on an existing plastic fork by burying it is quite irrelevant to the argument you are trying to make.
2. You are ignoring the reality that much non-recycled plastic is dealt with by incineration, greatly accelerating the CO2 release from plastic disposal. Additionally since landfills aren't limitless, filling landfills up with plastic will increase the attractiveness of other disposal options (namely incineration) for the portion of non-recycled plastic in the future.

#2 and #3 are also common problems with many types of petrol plastics.
Finally, on #4: tree branches and sticks degrade at similar rates to bioplastic. Yes, it's slow but you really don't want it to degrade quickly. If bioplastic degraded as fast as food scraps you would have to refrigerate your sporks.

Please note, what is now compacted in landfills will be uncompacted above ground for at least 180 days (really longer because ASTM6400 states that only 90% of material needs to degrade to meet the standard). Food contaminated waste pose special vermin problems. Odor is another constant problem. There is already a huge NIMBY problem in siting waste management facilities this would become an ever growing issue. If you want to see just how problematic this idea truly is, just watch what is going to happen in Seattle in the next few years, as the effects of laws recently passed on plastic foodservice products and plastic bags are realized. Pushed by the mayor and passed by the City Council based on the premise that the alternative materials would not be landfilled but composted, it will not be long before reality sets in and backtracking on the results will be required. But then, it will be a new mayor and City Council and they will not be responsible for having created the issue.
It's funny how there are always unintended negative consequences resulting from the efforts to make things be what we want them to be rather than what they really are.

I see a few responses that fall partially in line with my thinking on the issue.
First there is hunger in the world and there always will be (get over it people - some people will not change).
Second and more to the point is cellulose based products. Algae is one of the best for some things, Industrial Hemp which is workable for many products with existing equipment with very minor modification (ie can be put into use immediately).
And thirdly, to all who read and posted here THANK YOU, by arguing one side or another or supporting someone else you have started the process of making a difference.

1. Agriculture is actually slowly becoming in danger as land is becoming less and less usable for crops due to our overusage of these lands. Additionally, resources such as water to grow plants are becoming scarce in many places. Some environmentalists believe that depending on plants for alternative energy or in this case bioplastics can negatively impact the agriculture sector.
2 & 3. Bioplastics are not meant to be recycled although you are making a good point. Composting resources need to become more publicly available for such products. For now, it seems to be more convenient to use bioplastics (like bioplastic utensils) in restaurants where they can be collected as in loads.
6. I disagree with you on this part. Most bioplastics items are meant to be for short term use. The main argument against non-biodegradable plastics is that they're used for short term use but can take many years to decompose. If you're looking for long term use, then you should not be using bioplastics.
Overall I think the concept of bioplastics is great but I think it is still underdeveloped. Recommended solutions to make the product better are (1) making compost factories more publicly available, (2) attempt recyclable bioplastics.
Funny to stumble upon this while I'm researching when I regularly watch you on youtube. Hi Hank!

One point, concerning #1: Why make stuff out of it when you can eat it?
I find it interesting that noone has mentioned the enormous quantity of grain (corn) that is wasted to feed livestock for meat production.
As far as i'm concerned, bioplastic is a fledgling industry, and poses a far less threat to food resources than the production of meat.
Despite meat also being a food source, it is in my opinion, at least at current consumption levels, an unsustainable one.
People do not need to eat meat - or at least, such large quantities of meat.
Curently, approximately 40% of the world's grain (670 million tons) goes to feed livestock in order to produce meat for consumption.
Approximately 7kg's of grain produce 1kg of meat.
The statistics are staggering what could be achieved, if even just a small percentage of this grain was allocated to alleviate food insecurity.
Potentially, if people ate less meat, there would be more grain available for food, energy, and bioplastic production.
If bioplastic production were to stop on the premise that the grain should be allocated for food; there is no assurance that this grain would not be used to feed livestock in order produce meat.
Meat is not only less sustainable in terms of the energy to mass ratio of its production, but also because it consumes vast amounts of resources and generates vast amounts of pollution.
Additionally, meat is a food of the affluent, and most of the world's starving do not benefit from its production. Not that anyone actually benefits from an indulgent meat-diet; the correlation between cancer/heart disease and excessive meat consumption are strong.
Anyway, just a comment of interest in response to point #1.
One other comment in response to the rather hot-headed post by Matt in september 2008.
Algae is not a panacea for the world's energy/ climate change problems. There is no cure-all. A combination of the world's current and prospective renewable energy technologies will have to be harnessed and effectively distributed if we are to reign-in the adverse impacts of modern lifestyles on the world's climate system.
Bioplastics could well be one of those technologies, if supported and developed appropriately in time.
... I realise i'm almost a year late on this discussion.
oh well.
This is rad though - I recently got internet.
bye.

With plastic bag pollution being a rising concern, many shoppers need to start using reusable cotton canvas bags in order to stop the pollution.
Plastic bag pollution is very deadly and takes hundreds of years to break down. Even if the component is broken done, the deadly chemicals will go into the ground and water system. By reducing the usage of plastic bag, Earth can recuperate. That's why cotton bags should be used world wide to help reduce the pollution.
It is our generation to stop the pollution and start using cotton canvas bags as the solution. With global warming going out of hand from gas exhaustion, we don't need any more problems especially plastic bags that are harmful when broken down naturally. These broken down elements cause sickness and destruction to the air, soil and water system.
Use cotton canvas bags starting today as a way to stop the plastic pollution that is becoming a major threat to the environment. Our lives are threatened ever more from the growing usage of plastic bags. It is time you bring a canvas bag to shopping the next time you go to a supermarket.
