The “carbonauten minus CO2 factory 1” will start production of 4,000 t of CO2-reducing plastic granules annually at favorable prices in summer 2022.
Giengen an der Brenz. 03/17/2022 – Carbonauts announce that funding has been secured for the first extruder to produce plastic pellets with up to 70% biocarbon content. A total of around two million euros is being invested in the plant, which will go into operation at carbonauten’s pilot site in Eberswalde from the middle of the year. It will produce more than 4,000 tons of plastic granules annually starting in the fall. The special feature of the material is the admixture of biocarbon, which is also produced at the biorefinery in Eberswalde by a special carbonization process. Its CO2-absorbing properties replace fossil raw materials and make the resulting composite material attractive from an ecological point of view; moreover, the price is extremely low compared to petroleum-based plastics. In addition, the admixture improves properties such as thermal and mechanical load-bearing capacity as well as UV and temperature resistance. The carbonauts expect demand to exceed the production quota and are already planning dozens of additional plants around the world.
At the Eberswalde site, carbonauten will start producing up to 7,500 metric tons of biocarbon annually from regional bioresidues this year. Through dry distillation, each ton of biocarbon permanently stores up to 3.3 tons of CO2, making it not only climate neutral, but CO2 negative, “minus CO2” that is. Products resulting from this process are also particularly easy to recycle or can even be designed to be composted into valuable black soil (“Terra Preta”). These advantageous properties are also transferred to the composite materials that will be produced in carbonauten’s new extruder starting this year: The prospect is of a significantly more climate-friendly alternative to conventional products based on fossil sources.
The price is also convincing, beating out composites from other sources thanks to low process and raw material costs: “Our fundamental philosophy is that ‘eco’ has to be cheaper than ‘non-eco’; and that also applies to our plastic products,” explains Torsten Becker, founder and managing director of carbonauten. “We’re not kidding ourselves about that: We already have so many customers for the new plant because we can offer our granules at favorable prices, and not predominantly because of the ecological advantages and better properties.”
The customers for the composites from the carbonaut plant are from the German premium automotive industry, but also from the plastics and packaging industries, as well as from the agricultural and construction sectors. “In addition to the lower costs compared to fossil-based composites, the advantageous material properties also play a role there, of course,” explains Torsten Becker. The automotive industry, for example, benefits from the robustness of composites with biocarbon content combined with low weight, he said. “And mulch films for agriculture on this basis don’t have to be burned or disposed of, but can be added to the soil as fertilizer after use – again saving costs, improving water-holding capacity and replacing artificial fertilizers.”
The carbonauts expect to have amortized the investment costs after just one year through sales of composite materials. And since demand for low-cost, high-quality and climate-friendly composites is not only already high but is set to increase worldwide in the future, carbonauten is already planning to build more plants around the world. “The shortlist includes around 30 locations in Austria, France, Spain, Italy, Montenegro, but also Panama, Colombia, USA, Canada and Brazil,” says Torsten Becker.
For these and other projects, the minus CO2 factory is open to partnerships.
