Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The rubber composition effectively absorbs CO2 from the atmosphere or road surface, offering cost savings due to the lower cost of olivine compared to conventional raw materials, while maintaining the performance and mechanical properties of the tyre.
Implementation Method 1
Magnesium rich olivine is known to be a natural CO 2 absorber by converting it into stable carbonate byproducts in the presence of water via the following reactions: CO 2 + H 2 O ↔ HCO3 + H +
Implementation Method 2
Mg 2 SiO 4(s) + CO 2 ↔ 2MgCO 3(s) + SiO 2
