New Bioplastic Reinforced With Natural Fibres

17.04.2003


Finland Leads Europe In The Development Of Biodegradable Plastics



VTT, Technical Research Centre of Finland, has made degradable bioplastic more durable due to reinforcement with natural fibres. This biocomposite, which is totally biodegradable, supports sustainable development. The waste costs for products made from this will be small, and in the future consumers will have an enhanced appreciation of biodegradability of materials.

VTT achieved this biocomposite using flax fibres to reinforce bioplastic. VTT also developed a method by which the properties of the completely biodegradable biocomposite can be tailored according to the projected use of the product. It is a further advantage that the new bioplastic products can be manufactured on the same machinery on which conventional plastic products which are only partially biodegradable are manufactured.


The spearhead in the development of such flax reinforced completely biodegradable products has been in Finland, Sweden and the USA. VTT research succeeded in creating the desired mechanical strengths for bioplastic through an appropriate combination of bioplastic raw material and flax. The research also explored the resistance of the new biocomposite to heat, moisture and UV radiation, and further developed the manufacturing process.

Fibreglass has traditionally been used to reinforce plastics. This is difficult to recycle and there may be health hazards involved in handling it. In central Europe the car manufacturing industry especially uses flax fibres for reinforcement, but mixed with non-biodegradable plastic raw material.

“Our company acquired knowledge suggesting that it would be good to continue working on product development and research in order to bring new, biodegradable materials onto the markets. One year ago an EU norm was set for bioplastic, and in the next few years compostible packages are to come onto the markets of southern Europe. Finland is the leader in Europe for completely biodegradable bioplastic. Much of the credit is due to TEKES and its biopolymer programme,” says Anders Södergård, technology manager of the Dutch company Hycail and part-time professor of applied biomaterial sciences at the University of Turku.

The research work on biocomposites led by VTT was financed by TEKES, several companies and VTT. The companies specified the desired properties for bioplastic and the research work was accomplished chiefly by VTT, Tampere University of Technology, Åbo Akademi University and Hycail. Hycail has a pilot factory for lactic acid based bioplastic raw material producing 400 tons of raw material a year.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
