Die Windenergie ist essenzieller Bestandteil der Energiewende und damit Hoffnungsträger für Deutschlands Nachhaltigkeitsstrategie bis zum Jahr 2045. Doch rund ein Drittel der Windkrafträder in Deutschland haben ihre vorgesehene Nutzungsdauer bereits überschritten und stehen laut Fachagentur Wind und Energie kurz vor ihrem Abbau. Wir haben mit unserem Recycling-Experten für Verbundmaterialien – Fabian Rechsteiner – gesprochen, was mit den ausrangierten Anlagen passiert. Dabei gibt der Experte auch spannende Einblicke in die technischen und politischen Herausforderungen, die auf dem Weg zu einer Kreislaufwirtschaft im Bereich Windenergie noch zu überwinden sind.

Warum werden in Deutschland viele Windenergieanlagen über ihre technische Lebensdauer von 20 bis 25 Jahren betrieben?
Wir als Endverbraucher kaufen den Strom immer zu dem Preis der teuersten Stromerzeugungstechnologie (Merit-Order) ein. Aktuell ist das Gas, das mit rund 11 Cent pro Kilowattstunde zu Buche schlägt. Windenergie kann hingegen unter optimalen Bedingungen sehr günstig produziert werden. Der Preis pro Kilowattstunde liegt derzeit bei rund 4 Cent. Darum ist es für Betreiber meist rentabler, ihre Anlagen 30 Jahre und länger zu betreiben. Sie sparen sich damit aufwendige Genehmigungs- und Planungsverfahren für den Bau neuer Anlagen. Das dauert in Deutschland leider oft zwischen sechs und acht Jahre. Auch die Logistik und der Transport neuer Anlagen sind komplex. Die Bauteile sind so groß, dass ihr Transport auf den Straßen und unter Brücken Millimeterarbeit ist. Nicht selten müssen dafür Bäume gefällt werden. Das stellt Betreiber vor eine Vielzahl von Herausforderungen und hohe Kosten. Die Alternative heißt dann oft Repowering. Dabei werden alte Anlagen mit Neueren ausgetauscht. Da der Standort bleibt, ist die Genehmigung dafür auch deutlich schneller zu bekommen.

Und was passiert mit den Anlagen, die nicht mehr weiterbetrieben werden können?
Die Anlagen werden abgebaut und recycelt. Der Turm aus Stahl wird wiederverwertet und das Fundament aus Zement wird zum Beispiel im Straßenbau genutzt. Das umfasst fast 90 Prozent der Anlage. Die größte Herausforderung stellt jedoch das Rotorblatt dar. Das besteht meist aus einem bunten Materialstrauß wie faserverstärkten Kunststoffen, Holz, Schaum, Metallen und vielem mehr. Leider machen sich Hersteller noch nicht allzu viele Gedanken darüber, was am Ende mit dem Material passiert. Auch politisch ist recyclinggerechtes Konstruieren noch nicht so stark eingefordert, wie es meiner Einschätzung nach sein sollte. Das macht das Recycling auch so schwer. Abhilfe könnte ein digitaler Produktpass schaffen. Durch ihn lassen sich die Materialien, die in Rotorblättern verbaut sind, besser nachzuvollziehen. Viele Windräder sind rund 30 Jahre alt und niemand weiß mehr genau, welche Materialien damals verwendet wurden. Aktuell gibt es noch keine standardisierte Dokumentation oder ein System, das diese Informationen langfristig speichert. Wenn man die Rotorblätter recyceln will, ist es aber wichtig zu wissen, welche Materialien verwendet wurden. Das wäre ein wichtiger Schritt, um das Recycling zu optimieren. Da das bislang noch nicht der Fall ist, arbeiten wir am Fraunhofer IGCV daran, Recyclingprozesse zu entwickeln, die diese Materialien besser verwertbar machen.

Wie sehen diese Recyclingprozesse konkret aus?
Wir verwenden einen Pyrolyse-Prozess, bei dem der zerkleinerte, faserverstärkte Kunststoff unter Ausschluss von Sauerstoff erhitzt wird. Das passiert unter Stickstoffatmosphäre, damit der Kunststoff nicht verbrennt, sondern sich thermisch zersetzt. Das Ziel des Prozesses ist es, die Fasern– meist Carbon- oder Glasfasern – vom Kunststoff zu trennen. Im Anschluss versuchen wir aus der Faser wieder ein Textil zu gewinnen. Die Fasern verarbeiten wir dann nicht mehr in ihrer ursprünglichen, endlosen Form, sondern als kürzere Varianten zu einem Vlies. Eine Herausforderung liegt für uns darin, die Fasern so gerichtet wie möglich in diesem Vlies anzuordnen. Denn je zielgerichteter und gleichmäßiger die Faser, desto besser sind die Eigenschaften des Vlieses in die gerichtete Richtung und desto ähnlicher sind sie neuen Materialien, was wiederum ihren Einsatz vereinfacht. Um das zu erreichen, entwickeln wir bei uns einerseits die Recyclingprozesse und andererseits die Anwendungsprozesse und Fertigungsprozesse aus den recycelten Fasern. Wir charakterisieren und analysieren die Eigenschaften der Recyclingmaterialien und vergleichen sie mit neuen Materialien.

Was unterscheidet denn das recycelte von neuem Material?
Die recycelte Carbonfaser hat größtenteils vergleichbare Eigenschaften. Das würde ihren Einsatz zum Beispiel sehr interessant für die Automobil- oder Sportindustrie machen. Ausnahme bilden Anwendungen mit sehr hohen Anforderungen an die Struktur. In einem neuen Rotorblatt oder in der tragenden Struktur eines Flugzeuges wird man das recycelte Material daher nicht finden. Aber das ist ja auch gar nicht der Anspruch.

Wie steht es um die Forschung zum Recycling von Rotorblättern?
Die Prozesse sind schon weit entwickelt, sodass wir jetzt in die industrielle Umsetzung gehen könnten. Es gibt bereits Unternehmen, die sich in Deutschland mit Rotorblatt-Recycling beschäftigen. Das größte Problem ist jedoch, dass es noch keine ausreichende Nachfrage nach recycelten Materialien gibt. Viele Unternehmen scheuen Investitionen, weil der Markt noch unklar und unsicher ist. Politische Maßnahmen wie eine Recyclingquote wären hier sehr hilfreich, um die Nachfrage nach recyceltem Material zu steigern und die Wirtschaftlichkeit zu verbessern.

Fabian, zum Abschluss – gäbe es einen Wiederverwendungszweck für recycelte Windkraftanlagen, über den du dich ganz persönlich freuen würdest?
Da ich ein begeisterter Radfahrer bin, fände ich es natürlich großartig, wenn das recycelte Material in meinem Fahrrad landen würde. So würde sich nicht nur wirtschaftlich, sondern auch für mich ganz persönlich der Kreislauf schließen.
