Rice, C-Crete team optimizes conversion of tire waste into graphene for stronger concrete

Green Car Congress

Rice University scientists and their colleagues at C-Crete Technologies have optimized a process to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete. Concrete is the most-produced material in the world, and simply making it produces as much as 9% of the world’s carbon dioxide emissions.

New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. Accounting for evaporative emissions (e.g., Average emissions densities from Shen et al.
