Product description

Filaments made of PLA (polylactic acid) are gained from plants, i.e. from regenerative materials and not from raw oil as practised up to now.
PLA originates from solar energy, CO2 and water. With help of the sunlight the plant absorbs carbon from the atmosphere (photosynthesis) and stores it as starch. PLA is thus produced from CO2, a gas that is found in today's climate.
The starch is transformed into sugar. This vegetable sugar (dextrose) is the basis for the new plastic. A high-tech bio refinery transforms the carbon contained in the sugar into a plastic polymer by means of fermentation, separation and polymerization.
PLA can generally be produced from any plant that contains starch, e.g. sugar beets or corn. Presently, fodder maize serves as a sugar source. In the medium term, however, other vegetables are planned to be used as raw materials, for example agricultural by-products.
The biodegradability of PLA is yet another advantage of the material. Biodegradation requires however certain environmental conditions as usually given in industrial composting plants. In such a plant, PLA fully degrades within a few months. In nature, however, PLA will hardly degrade.
