A biodegradable band-aid made from birch bark and rice
The Birch-Aid is one of the many possibilities of materials exploration of birch bark and rice. This project is a material exploration which builds upon the previous rice plastic project. This project aims to reexamine the possibilities of natural materials and discovers a potential substitute for plastic in the context of medical use.
Bio Design / Sustainable Design
Do you know most band-aids are made of plastic?
Pvc, the material used for producing band aid, is one of the most toxic plastic for both our health and the environment.
Introducing Birch-Aid, a 100% biodegradable bandage made from birch bark & rice.
Do you also know many of us used band-aids in the wrong way?
If we don't clean the wound before applying the band-aid, it might cause infection and delay healing.

Safe and easy in simple steps
Founding from my personal experience
When I was little I loved playing outside in the birch tree yard near my home. Sometimes I stumbled upon stones or stumps and scratched myself.
Whenever I fall and bleed, my dad always peels a piece of birch bark and place it on top of my wound to stop the bleeding. He always has some fun facts to share about this magical tree with me.
So...Any other possible uses of the birch trees...?
Explore Birch Bark Pattern
I cutted the birch bark in different shapes to create different patterns
After multiple attempts to create different patterns with birch bark, I hope to push further my exploration by experimenting with medical properties of this material.
What makes people around the world use birch bark as medicine...?
Betulin has antiretroviral, antimalarial, and anti-inflammatory properties
“According to the research, Betulin from birch barks helps the damaged skin around wounds to regenerate more quickly”
Pictures on the left show the progression of the treatment of the wound over ten days. For comparison, the left side is treated with standard gel and the right side is treated with the birch-bark gel

Explore other potential materials at the school library
I found a material (Rice Sponge) that closely related to my birch bark research. So I incorporated this new material into my research and design
The Use of Rice in Medical Applications
Understand the potential of rice through researching at the material library and contacting the manufacture in Thailand for experiment samples

Experiencing the material
- Increases the recovery potential
- Medical Use
- Bio-based Alternative
- Strong water absorption
- Low production cost /simple tech - Decomposed in the human body
- Biodegradable organic substance
Once applied to the bleeding area, it quickly absorbs liquid allowing for coagulation to occur faster.
Combine Birch Bark, Rice Sponge and Rice Plastic
I used the bioplastic made from the previous Rice plastic experiments project as the sticky layer
I glued the rice sponge to the inner layer of the band-aid, placed it in a regular package, and tested its usability
