The sponge industry involves the harvesting and processing of natural sponges, primarily from marine environments. These sponges are used for various purposes, including personal care, cleaning, and artistic applications. The most common types of sponges come from the Mediterranean Sea and the Caribbean Sea, where they are collected by divers or through sustainable farming practices. In addition to natural sponges, the industry also includes synthetic sponges made from materials like polyurethane. These sponges are widely used in households and industries due to their versatility and affordability. The sponge industry plays a role in local economies, particularly in coastal communities where sponge harvesting is a traditional practice.
