Dr. Greg Keoleian of the University of Michigan and his team proposed in September that CO2 can be used to make concrete. That has turned out to be true. In fact, CO2 is also used to make diamonds, and clothing.
CarbonCure Technologies makes technology that injects CO2 into fresh concrete and strengthens it by locking in the carbon. Aether Diamonds utilizes captured CO2 to grow diamonds in a lab. Lululemon Athletica made a polyester yarn from carbon emissions with LanzaTech for products in the near future. These tech startups are already attracting investors, and collectively are raising billions of dollars in funding this year.
