What Is BIO EVA SW GREEN? How Can Sugarcane Become Part of a Sandal Sole?

To understand BIO EVA SW GREEN, we first need to understand EVA, or Ethylene Vinyl Acetate.

EVA is a widely used polymer in the footwear industry. It can be formulated into lightweight, flexible foam that provides cushioning and comfort during everyday movement.

Traditionally, EVA has been produced using raw materials derived from fossil resources, particularly petroleum and natural gas.

However, bio-based EVA offers another possibility.

BIO EVA SW GREEN focuses on developing footwear foam using EVA that incorporates sugarcane-derived renewable raw materials.

Instead of relying entirely on fossil-based feedstocks, part of the material’s carbon content can originate from biomass.

The general production process can be explained through five stages:

Sugarcane → Bioethanol → Bioethylene → Bio-based EVA → Foam Sole

First, sugarcane is processed to produce bioethanol.

Next, bioethanol can be converted into bioethylene through a chemical process.

Bioethylene is then used as one of the raw materials for producing bio-based EVA, which can eventually be formulated into foam for footwear applications.

Importantly, this does not mean sandal soles are made by directly compressing sugarcane fibers.

Instead, the innovation involves changing the origin of certain raw materials used in polymer production.

The resulting bio-based EVA can be developed to deliver performance characteristics similar to conventional EVA, including flexibility, cushioning, and lightweight comfort.

However, actual performance depends on the material formulation, manufacturing process, and footwear design.

For the footwear industry, this creates an opportunity to explore alternative materials without necessarily compromising the essential qualities consumers expect from their sandals.
