New U.S Patent awarded to SGI
A new U.S. Patent was awarded to SGI over the summer to protect its intellectual property related to SGI roofing products.
- U.S. Patent 11,999,655, “Building Materials Comprising Carbon Dioxide-Treated Agglomerated Particles,” was issued June 4 with SGI Manager, Research and Development Peter Wilson, PhD, named inventor.
The new patent covers the method used to treat silicate-bound agglomerates of SGI’s pulverized rock fines with carbon dioxide gas to insolubilize the agglomerated particles to meet the performance demands of applications such as roofing.

It is the first U.S. Patent awarded to Wilson and the third awarded to SGI in 2024.
