- "Tire dust makes up the majority of ocean microplastics" https://news.ycombinator.com/item?id=37728005
- Taraxagum is extractable with just water FWIU
- Would GMO dandelions be easier to scale up with traditional and vertical gardening? How could dandelions be genetically-engineered for use in sustainable tires? Larger stems, less or no seeds to avoid clogging up vertical gardening,
- What are some uses for the non-stem waste part of dandelion flowers?

> Abstract: A new polymeric composite based on natural rubber reinforced with hemp has been processed by electron beam irradiation and characterized by several methods. The mechanical characteristics: gel fraction, crosslink density, water uptake, swelling parameters, and FTIR of natural rubber/hemp fiber composites have been investigated as a function of the hemp content and absorbed dose. Physical and mechanical properties present a significant improvement as a result of adding hemp fibres in blends. Our experiments showed that the hemp fibers have a reinforcing effect on natural rubber similar to mineral fillers (chalk, carbon black, silica). The crosslinking rates of samples, measured using the Flory-Rehner equation, increase as a result of the amount of hemp in blends and the electron beam irradiation dose increasing. The swelling parameters of samples significantly depend on the amount of hemp in blends, because the latter have hydrophilic characteristics.
Is there a dandelion hemp blend that's good for tires?
Michelin has rice byproduct in their current Most Sustainable Tire.
Maybe dandelion stems, some part of the industrial hemp plant, and rice byproduct?
With processing by IDK cheaper Electron Beam Irradiation too?
