Conscious Design

Materials & Components

We challenge and push design and product development boundaries to make luxurious products in a way that is fit for the world we live in today and tomorrow, both beautiful and sustainable. No compromises.

Innovative Materials
Compostable Leather

Nature-L ® Leather

This Nature-L ® leather been designed to degrade by 75% in the first 90 days of composting, compared to standard leather which degrades by only 7.8% in the same conditions. This leather uses less water than the traditional tanning process and reduces waste as cut-offs are composted. It also reduces the amount of dye needed because of the improved colour intake. 32% of leather uppers and 87% of linings are made of Nature-L ® leather. 


chrome-free leather

Chrome-free leather has been tanned without the use of heavy metals.This reduces impurities in waste waters created during the tanning process. The leather is produced in a closed cycle so water can be recycled, and overall water-consumption is reduced. 16% of leather uppers are made of chrome-free leather.



PYRATEX® cosmetic VI is a new fabric made of crushed, ground seaweed and eucalyptus wood cellulose. It is a 100% organic fiber, free of toxins, completely biodegradable, carbon neutral, and OEKO-Tex® 100 certified, with amino acids, vitamins and minerals that are beneficial for the skin.

For this capsule collection we used a heel embedded with glass Swarovski crystal pearls.




Our veg-tanned leather soles represent 68% of all Autumn Winter 21 soles and are tanned only using natural tanning ingredients. They are plastic-free and finished using a brushing technique.

71% of the plastic TPU sole is now plant-based. Fossil fuels have been replaced with castor bean oil and sugar cane, reducing overall carbon emissions. Plant-based soles represent 18% of our Autumn Winter 21 soles. Only 13% of all soles are not made using conscious materials. These include rubber soles that are not yet plant-based and some high-gloss finished leather soles. 


We're working on it

Metallics used in the collection are not compostable, however, we have significantly reduced the use of metallics in the collection compared to the past.

We are still researching and testing natural alternatives. We used glass Swarovski crystal pearls for the Ocean Day Capsule collection.

Currently, 66% of our carry over styles feature conscious uppers, while 87% use Nature-L biodegradable linings. This is something we are aiming to improve and increase each season.

Many of the soles on the Casati family still use a rubber sole. We are continuing tests to change this and looking for natural alternatives.

We are currently experimenting with high quality compostable calf leather, which looks promising, and we hope to use it in future collections. Because of our design ethos we won't compromise on a material unless it is right, but we have moved towards using metal free calf in the meantime.

We are currently looking into compostable alternatives and conducting research on bio-based materials that have the same performance as ABS.
