About us

The Croll & Denecke family enterprise

Croll & Denecke was established by Gustav Croll and Theodor Denecke in 1897. Today Peter, Nina and Sara Hankiewicz run the family enterprise, which is specialized in processing raw natural sponges from the Mediterranean and the Caribbean, in the third and fourth generation.


Based on know-how handed down for over a century, the family enterprise in Bremen has developed into the leading supplier in the natural sponge trade in Europe and now sells its high-quality products in over 50 countries worldwide.


Aside from natural sponges, the medium-sized company also offers further wellness accessories appreciated all over the world. Natural luxury is a tradition at Croll & Denecke – that includes responsible and environmentally compatible use of raw materials provided by nature.

The sea has always fascinated people. Out of its unfathomable depths come things that amaze us and make us pause and reflect. But also the small, initially rather inconspicuous things given to us by the sea can be genuine good luck charms.


Natural sponges, the products with which everything started back in 1897 and which still represent the focus of the Croll & Denecke family enterprise, are a sustainable wonder of nature. Through careful manual treatment and preparation, the sponges are processed into a special and indulgent wellness accessoire. Thanks to their rapid growth, natural sponges are a prime example of sustainability and, like all products from Croll & Denecke, combine something very special with their simplicity: unspoiled luxury from nature that pampers body and mind.


The company’s success is boosted by the untiring passion of its managing directors and staff for high-quality wellness products. Right from the beginning, the paramount goal of Croll & Denecke was sustainability – in both the manufacture and development of its products as well as in staff management.

Sustainability and environmentally friendly use of raw materials from the sea through traditional formulas
are fundamental elements of Croll & Denecke’s business philosophy.
