With the first refill pack for ornamental fish JBL brought sustainability to the field of aquatics many years ago. Things then started to move at a rapid pace: from energy-efficient cars for the JBL sales force, to a huge photovoltaic system on the roofs of the JBL plant in Neuhofen, to the current refill packs of the JBL water treatment JBL Biotopol and the plant fertiliser JBL Ferropol. Now the aquarium enthusiast can also contribute to the protection of the environment, and the savings are tremendous. One truckload with refill bags corresponds to 17 truckloads of hard packaging, which in its turn corresponds to a CO2 saving of 94 % during the transport!
