10 years ago Published in bioplastics MAGAZINE 10 YEARS AGO new series “Basically, the information in the article is still true today. However, the bioplastics market has diversified and developed enormously over the past ten years with new innovative materials and a broader spectrum of end-of-life-options. Today, we define bioplastics as plastics that are bio-based, biodegradable, or both.”, says Constance Ißbrücker, Head of Environmental Affairs at European Bioplastics, the successor organization of the former IBAW. Basics Fig 1: Ideal closed loop life cycle of biodegradable products (courtesy of IBAW) Definition of “Bioplastics” To say it right from the beginning: A clear definition of “bioplastics” that would be agreed upon by all parties involved worldwide does not exist. Even though bioplastics magazine will try to make a first step by formulating a draft. Our readers’ comments on this draft are always welcome and may lead to an updated definition in one of the coming issues. The idea of bioplastics The basic idea behind bioplastics is taken from nature‘s cycle. Worldwide, more than 100 billion tonnes of organic material is generated every year by photosynthesis. Most of it is subsequently converted back into the starting products, carbon dioxide and water, by micro-organisms. This cycle is the role model for bioplastics, that are often made from renewable raw materials obtained from agricultural production. When biodegradable plastics (or certain other products in general) have served their purpose, they can be composted - a recycling method for which bioplastics are highly suited [1]. This leads to a first try of a definition ... Bioplastics are man-made plastics (polymers) which can be processed by established plastics processing technologies such as injection moulding, blown or cast film extrusion, blow moulding, extrusion etc. and which are A) based on (annually) renewable raw materials (RRM) or B) biodegradable. Annually renewable raw materials are plants like maize/ corn, rapeseed or soy from which, e.g. starch or edible oils can be harvested, which in turn can then be converted into thermoplastic polymers. The biodegradability is defined by different standards, in Europe, for example by the EN 13432 standard. Products that are candidates to be classified as biodegradable or compostable have to be certified by independent entities and then receive an appropriate logo (see page X for an example) Both aspects of being based on renewable sources and being bio-degradable have been fulfilled for most of the so-called bioplastics that are already commercially available. However, there are also materials available that are, for example, biodegradable, but based on crude oil, or even blends or other combinations of polymers that are partly made of RRM and partly of crude oil. Other materials are based on (or even only partly based on) renewable sources, but are not biodegradable. These are for example polyamides (11 or 6.9) based on castor-oil or tallow, polyesters containing bio-based 1,3-propane-diol, polypropylene with wood fibre fillers, polyethylene-starch blends or polyurethanes with polyols based on sugar or fatty acids. Here the definition becomes difficult ... On one hand, in view of limited crude oil resources and rising prices, the aspect of sustainability, and therefore also the use of RRM, is becoming increasingly more important. So even materials that are only partly based on RRM can be a useful approach, especially when properties are achieved, that cannot be achieved with materials based 100% on RRM. But what should be the minimum percentage of RRM for such a material to be called a bioplastic? On the other hand, if a polymer is based on renewable sources, should it necessarily have to also be biodegradable? If such a material is incinerated, for example, with exploitation of the energy stored within it, there is a neutral effect on the climate. The amount of carbon dioxide emitted during incineration is less or equal to the CO 2 that was absorbed by the plant during its growth. A completely different group of materials are so-called oxo-degradable polymers, sometimes referred to as oxo- This series is to be continued. Topics in the coming issues are listed below. Bioplastics magazine encourages its readers to contribute their knowledge for the coming “Basics” features. Bio-degradation What is degradation? What about degradation in water, in soil, elsewhere? What is composting? What happens in an industrial composting plant, what happens in home composting? Do we have enough agricultural space to grow “bioplastics” How much space is needed to produce one kg or one tonne of bioplastics? What about the growing need for agricultural space for other bio-based products like bio-fuels and chemicals based on renewable sources? Further topics Definition of “sustainability” How is maize/corn converted into PLA? How do bacteria make PHA? How is PHA made from switchgrass? How is starch converted into plastics? etc. toxicity. The so-called “oxo-biodegradable” polyethylene (PE) products may fragment into very small particles after exposure to UV light or dry heat. PE is however still to a large extent resistant to biodegradation after fragmentation, and there is therefore potential of high persistency in the environment and bioaccumulation of liberated regulated metals and PE fragments in organisms due to the slow process. None of the oxo-degradable polymer products has ever been proved to fulfil the EN 13432 standard. They seem to be outside the range of the bioplastics class, although some of their protagonists may like to see them included [2]. A lot of open questions.
