Gary Winnick, the investor who founded the once-mighty telecommunications giant Global Crossing, has gone green.

Winnick is the chairman and founder of iCrete, which says it can reduce the carbon content in concrete by 40 percent. Manufacturing concrete and cement are two of the largest contributors to greenhouse gas emissions. Winnick also continues to be the CEO of Pacific Capital Group.

The company has developed algorithms that let engineers and contractors optimize the concrete going into a particular site for strength and durability while at the same time maximizing LEED points. The secret sauce is that iCrete can reduce the amount of cement paste in the aggregate concrete mix by increasing the voids. Additionally, iCrete-fashioned concrete dries quicker than regular concrete, thereby shortening construction time. The company claims that the technology also allows builders to reduce the amount of steel that goes into a structure.
