Bioplastics - cleaner world or bigger mess?

Sylvie Barak

5/24/2012 1:18 PM EDT



With energy resources dwindling and "sustainability" becoming a must-have word in the lexicon of almost every company in the developed world, the debate over the use of cleaner materials is intensifying, especially when it comes to plastic.

Some claim the "war on plastic" is unjustified, with people to blame for pollution rather than the material itself, while others argue that taking simple steps to replace traditional plastics with more natural biological substitutes would cut back on carbon emissions drastically.

One such company is the Italian firm Novamont, whose starch-based Mater-Bi  bio-plastic is already widely used in supermarket shopping bags and even tire treads.

Novamont was originally established back in 1989 under the name Fertec, a research center with the aim of combining the study of chemistry and agriculture to produce fuel and materials more conducive to the principles of environmental sustainability.



Fertec’s basic philosophy was that the environment was something able to propel the development of a business that was economically sustainable and competitive on a large scale. As such, the firm plowed money, time and resources into looking for natural alternatives to various materials, bio-fuels, lubricants, detergents and even paper.

Despite the fact that bio-fuels could indeed be created from crops, however, scientists quickly discovered that the process was simply not sustainable.

The annual worldwide demand for fuel required is around 1.5 billion metric tons (and is rapidly increasing). In no way could this need be covered by food crops because the entire planet would not provide sufficient space for the planting required.

Looking at the figures, total corn production worldwide --one of the crops most widely used in the bio-fuel industry-- is 700 million metric tons. Italy produces around 10 million metric  tons and cannot even meet the requirements of its human food and animal feed sectors, being forced to import much of its needs.

On the other hand, scientists posited, just 70,000 hectares of corn and 600,000 hectares of oleaginous non-food crops would be sufficient to meet Italy’s total requirements for packaging plastics, amounting to some 2 million metric tons. Considering that Italy’s cultivatable lands come to 15 million hectares, Fertec reasoned that bio-plastics would not adversely affect the food chain and, indeed, might even strengthen it.

Thus, in 1992, the firm decided to focus solely on the creation of bio-materials, changing its name to Novamont in 1994. Today, Novamont is the largest European company producing bioplastics using vegetable components, having invested upward of 120 million euros in developing a broad range of products from vegetable raw materials.

Novamont became a profitable company in 2001 and is currently on track in 2012 to see a turnover of some 200 million euros, with a staff of around 150 people, 30 percent of whom are employed in research and development.

Still today the company consistently reinvests 10 percent of its profits into further R&D at its plant near Turin in Italy.

Great story Sylvie, what's not to like about bioplastic? Give me some bioplastic coffee cups! (I am dispose two of them daily and feel bad about it)...Kris

It goes without saying that whatever is manufactured out of renewable material, typically stuff that can also be used for food, instead of being made from another non-renewable source, such as oil, will require more of that reneable material to be produced than previously.

SOMETHING has to be used instead of the oil.

I'm not sure I understand why Lloyd Alter should assume that this translates to less food on the table.

Also, what is the PRACTICAL alternative to having biodegradable plastics, made from renewable materials, for such throw-away applications like plastic cups and bottles? Glass? How long does that take to degrade? Paper or carboard? How many trees do we need to harvest for that?

Everything in nature comes at a price. Even food for animals in the wild comes at a price, to some other plant or animal. Even recylcing of non-degradable objects comes at a price. All we're doing here is trying to lower the overall price.

alternative to plastic cup - a ceramic mug you use many times over.

alternative to disposable plastic bottle - any form of bottle that you refill

The primary shift is not in the material used but in the model for distribution of the stuff in the container ie locally refill rather than have new ones sent from far away each time in a "use once then throw away" container

That's just it, though. Ceramic mugs are NOT an alternative, not in the use cases where plastic or paper cups or utensils are used.

People do use ceramic mugs, when there's no problem washing them and putting them away. Such as, at home or in restaurants. People use throw-away dishes and utensiles when the cost of washing and reusing the utensiles is too high. Street vendors, for instance. Do you really expect concession stands or roach coaches to have dishwashing pacilities? Or do you really expect people to carry dishes, cups, and utensiles with them, when they go to a concession stand, and then carry the dirty dishes home for washing?

Take the case of milk bottles and soda bottles. They also used to be returnable, but there were costs associated with that too. People often didn't return them, which caused a problem, and they had to be sanitized and recylced when they were returned, which itself wasn't free. Then came non-returnable glass bottles. Not much better. They are recycled, when not just thrown out in the trash, much as plastic can be. But they're heavier and cost more all around (transportation, etc.).

So all of this is a balancing act. To vilify plastic, in a vacuum, just doesn't make any sense.

A great journey from 1994 to 2012. The continuous R&D by this company shows their strengths in bringing out the best to us. This area of R&D if focused by all major multinational companies for improving their packaging needs then very soon we will get a right low cost solution.

Biodegradable plastic is a temporary solution. We cannot be callous about our approach to waste of any form. A simple change in daily behavior can lead to formidable impact. For example, taking a shopping bag can reduce a huge amount of the plastic waste, using ceramic mugs or bottles for drinks whenever possible can reduce burden on natural resources. We always complain that people do not change their habits but we will have to.
