Yem üretiminde enerjiyi adeta yutan UV-C atık hava arıtıcısı yerine aynı zamanda 10.000 litre aktif kömürün kullanılmasını (ve giderilmesini) gereksiz kılan büyük hacimli biyofiltreler kullanıldı.
Very special care is taken in the production of fish food: Protecting the natural fish stocks of the oceans is the top priority here. Not a single fish has to be caught for JBL fish food! JBL uses only fish meat left over from fish fillet production, according to the motto: "The large fillet for humans and the small fillet for our aquarium fish!" This is how high-quality, pure fish protein is obtained. Incidentally, this fish processing takes place in France. JBL strictly rejects the processing of whole fish from fish stocks that are already under threat and supports short transport routes to avoid overseas shipments for environmental reasons.
Anyone who has met the staff and the managing director, Roland Böhme, quickly understands that JBL is seriously interested in nature conservation.
