Rosenfeld sponge processing Ltd. has been in the business for more than 100 years. In Trieste, the opening of the Rosenfeld Ltd. was possible because of the hard work of David Rosenfeld in 1896. The city was under the rule of the Austro-Hungarian Franz Joseph I.
To date it is the oldest Sponge Processing Company in Europe.
The family, which for four generations continues to run the company, has made the processing of sea sponge a point of excellence: the family knows the secrets, the particularities and the waters where there are the best specimens.
Rosenfeld Ltd sponges come from the waters of the Mediterranean and the Atlantic sea. They are processed in the sponge processing plant in Trieste and exported worldwide. The purification and washing treatment, necessary to remove the impurities and organic calcareous substances from the spongeis done using traditional methods. The final inspection ensures the correct pH balance of the product. The shaping is the last part of the process, strictly done by hand to improve the shape and appearance of the sponges.
