Natural sponges and sustainable products

Bringing sustainability into everyday life

The power of nature meets craftsmanship

We focus on the power of nature – and have been doing so since 1897. In our family-run manufactory in Bremen, we refine sustainable natural sponges by hand. We once started small with this miracle from the depths of the sea.

Today, we are the market leader as a wholesaler – and our natural sponges are popular all over the world. Over the years, our product range has grown to include many sustainable care and household items.

Simple. Natural. Sustainable.

For radiant skin – with a clean conscience

Nature is unique. As is our skin: The largest organ of the human body has very individual needs – and is exposed to a lot of stress, different stimuli and often also the wrong care in everyday life.

With sustainably harvested natural sponges from the Greek Mediterranean and our environmentally conscious skin care products, we return naturalness to the skin.

Croll & Denecke: Your wholesaler for natural sponges and sustainable products

Sustainable all the way

At Croll & Denecke, we stand for sustainable and responsible action – all the way. This applies to the controlled and ecologically compatible harvesting of natural sponges, as well as to gentle processes during refinement, and the treatment of our business partners and employees.

Plastic? Not with us!

We want to make the world a little bit better and help nature to breathe. That is why we are gradually changing our products and packaging and trying to avoid plastic. By doing this, we save around one tonne of plastic waste per year – and we want to become even better in the future.

Please contact us by phone at +49 421 4367 49-0 or by e-mail at if you have any individual requirements. Many items can be ordered loose, for example, if our customers do not need individual packaging, helping us make a joint contribution to a clean environment.

Good for the environment – Good for the skin

We refine up to 3000 natural sponges a day by hand in our manufactory in Bremen
