Balena is a materials science company developing compostable and biodegradable thermoplastic materials. The company aims to create a circular model for consumer products in order to ensure sustainable production and consumption of materials, with an initial focus on the fashion industry. Balena is focused on helping global fashion brands find new, sustainable solutions to handle their products' end of life through circular materials.

The company's first developed material, BioCir, is a flexible and fully compostable thermoplastic material, reducing toxic, fossil fuel-based materials used in the fashion and footwear industries. BioCir can be used for 3D printing using filaments or in pallets for mass production injection molding.

Balena also has its own in-house product design studio that has designed and produced the first product made entirely of BioCir: the BioCir Slides, designed and manufactured in Italy.
