Recycelbar vs. wiederverwertbar
The German words recycelbar and wiederverwertbar are generally used as synonyms to mean "recyclable". The main difference lies in their origin and tone: recycelbar is a modern loanword from English used frequently in marketing and daily life, while wiederverwertbar is the descriptive, native German term often found in technical or formal contexts.
Recycelbar
B1This implies that an object can be processed industrially to recover raw materials. It is derived directly from the English word "recycle" and is the most common term used on consumer packaging, advertisements, and in casual conversation regarding trash separation.
Diese Plastikflasche ist zu 100% recycelbar.
(This plastic bottle is 100% recyclable.)
Achte beim Einkaufen darauf, ob die Verpackung recycelbar ist.
(When shopping, pay attention to whether the packaging is recyclable.)
Papier ist ein gut recycelbarer Rohstoff.
(Paper is a partially easily recyclable raw material.)
Das Symbol zeigt an, dass der Karton recycelbar ist.
(The symbol implies that the cardboard box is recyclable.)
Wiederverwertbar
B2This word combines "wieder" (again) and "verwerten" (to utilize or process). It is the formal German equivalent and is often used in official regulations, technical descriptions of waste management systems, or to emphasize that a material still holds value that can be extracted.
Alte Elektronikgeräte enthalten viele wiederverwertbare Metalle.
(Old electronic devices contain many recyclable metals.)
Der Abfall wird sortiert, um wiederverwertbare Stoffe zu sichern.
(The waste is sorted to secure recyclable substances.)

(Only recyclable materials are accepted at this facility.)
Summary
Use recycelbar for everyday situations, such as asking if a coffee cup goes in the recycling bin. Use wiederverwertbar if you are writing a formal report, discussing industrial waste processes, or want to sound more technical. However, native speakers will understand both terms interchangeably.
