Covestro has worked with leading Brazilian footwear manufacturer Calçados Beira Rio to develop a concept shoe that combines pioneering design with innovative, more sustainable material solutions

Both shoes feature Covestro products, which are made from alternative raw materials such as CO₂, biomass and plastic waste

.
These are valuable resources because they provide carbon that can be beneficially used in a circular economy, rather than being released into the atmosphere as exhaust gas
.
Covestro has pioneered the use of these raw materials to reduce reliance on fossil materials and increase the sustainability of the value chain
.

Go with CO₂ technology

One example of this is the upper and inner lining of these two shoes
.
The bottom layer is a soft foam that ensures a good fit and a comfortable foot feel
.
Here, a precursor product is used, which contains up to 20% carbon dioxide and is marketed by Covestro under the name cardyon®
.
CO₂ replaces some of the previously used fossil feedstocks without affecting the advantageous properties of conventionally produced foams
.

Both women's shoes feature two different types of thermoplastic polyurethane (TPU) in the outsole
.
One is also based on cardyon®; the other has 60% of its carbon content from biomass
.
As a result, both products have lower CO2 emissions than fossil-based TPUs, contributing to the carbon cycle
.

High heels made of recycled plastic

Covestro is also recycling plastic waste as part of its strategic plan to support the circular economy and is working with partners to develop new value-added cycles to achieve this
.
For example, used polycarbonate products are shredded, washed, possibly mixed with new plastic, and reused as recycled Makrolon®
.
In women's shoes, this allows for long-lasting strength in the insole and heel
.

solvent free

Footwear makers such as Beira Rio want to offer more sustainable products to benefit their customers, while also improving hygiene in production
.
This is why they are increasingly relying on water-based raw materials, which have significantly reduced emissions of volatile organic components (VOCs) compared to the solvent-based substances used in the past
.

INSQIN® technology is used in the lining, upper and heel of women's espadrilles, as well as in the synthetic upper material of casual shoes
.
The technology is based on waterborne polyurethane raw materials and has been specially developed for more sustainable textile coatings
.
A water-based adhesive containing the polyurethane dispersion Dispercoll® U provides the necessary strength to the upper and outsole of both shoes
