a material that
solves problems
Shaping the future of rubber together with nature
The footwear industry is under growing pressure to deliver real sustainability -yet truly renewable, high-performance materials remain rare. Reselo Rubber changes that.
We make use of birch bark, valorised through an efficient and benign bio-refinery process to an elastomer, to create a patented material that combines the performance of traditional rubber with a fraction of the environmental impact. Our birch bark rubber enables brands to stand out with genuine innovation, reducing reliance on fossil-based materials while keeping quality, durability, and comfort at the core.
By working with nature instead of against it, we’re helping the shoe industry move toward a more forward-looking future-one step at a time.
Making use of what otherwise goes to waste
In a world where nothing is infinite, we must consider how to best use everything extracted from Earth. Renewable resources offer preferred options over fossil-based resources from a sustainability perspective.
Still, even when we cut down a tree, it takes many years for the next one to grow back. Therefore, we make use of byproducts from the forest industry that have little market value today.
Today, birch bark is mostly burned as fuel, and instead of allowing it to go to waste, it finds new value as Reselo Rubber. This way, nothing goes to waste.
HOW RESELO WORKS
Reselo Outsoles
Our tap-in solution offers access to recipes and value chains that are already in place, that your brand can easily incorporate into your shoes. This way, you can quickly minimise the carbon footprint of your outer soles and strengthen your position as a sustainable brand.

Unique solution for your brand
We can also work together to develop a recipe and workflow that fits specifically your brand and process. We can alter your soles' texture, tone, flexibility and strength. This way we continue to develop our patented material in unique ways and stay at the forefront of sustainable innovation, in partnership and through collaboration.

OUR MATERIAL
100% fossil-free
Reselo Rubber has a biogenic carbon content of 100%. The biogenic carbon content analysis was performed by a third-party lab using a modified method of ASTM D6866-22.
Innovation champions
Our patented material is constantly developed further; by implementing Reselo Rubber into your shoes, you are at the forefront of innovation.
Sustainably sourced circular thinking
Made from FSC-certified birch bark, Reselo Rubber turns forest byproducts into sustainable value — supporting circularity and biodiversity.
Seamless Integration
Our material integrates easily into existing manufacturing processes and even improves rubber compounding efficiency.
Enhanced Performance
Our material contributes to hardness, slip resistance and tear-strength of your soles.
Non-toxic
Reselo Rubber has no toxic effects on terrestrial plants, i.e. it does not affect the germination and growth. The analysis was performed according to OECD 208.
