Shoe soles are being used for many purposes except protecting our sensitive feet from the harsh ground. Shoe soles can now track your location , activity , or can have a therapeutically beneficial design by correcting your posture. But what if it could do more not just for you, but for humanity?
Imagine the shoe sole that collects microplastics and rubber while you walk.
How would it work?
It could be made as a normal sole with "soft rubber pockets" which are made of materials that electrostatically bind microplastics and rubber. It could also be designed as a mop, by having millions of small ecologically acceptable fibers that "collect" plastic and rubber particles. It would require the user to dump the collected materials into the plastics container waste and repeat the collection.
It would help to reduce the microplastic around us by collecting it and also to reduce the amount of rubber that is "peeled" of the sole while walking.
Why would you invest in this?
If we find such a material and the concept proves to be beneficial, we could apply the same principle and put a layer of this "collecting material" on the bottom of the ships. That way, except algae and seaweed, people could remove the collected plastics and rubber from their ships' bottoms and help reducing the environmental impact of non-recyclable materials such as plastics and rubber.
