![]() ![]() ![]() Constantz founded Calera to address global climate concerns with aspirations to permanently sequester gigaton quantities of carbon dioxide in the form of carbonate minerals. Constantz as founder and CEO led three medical device companies to advance mineralization technologies for orthopedic bone cements.ĭr. is a Fullbright Scholar and the Founder and Chief Executive Officer of Blue Planet Systems Corporation, a serial entrepreneur with expertise in biomineralization. Listen to this episode as we talk about biomineralization with Brent Constantz.īrent Constantz, Ph.D. Mineralization of CO 2 is the most permanent form of sequestration of CO 2 that’s possible right now. If we can capture part of the 40 GTs of CO2 that would have entered the atmosphere, mineralize it (just as nature does with biomineralization via organisms) and put that into our concrete – we can solve a huge portion of our climate crisis. So… humanity currently uses 50 GTs of concrete a year. Limestone – the most common type of rock to be mined and transported for concrete – is actually made up of CO3 (carbonate) and calcium. Sounds like a lot? It’s just a little over 10 yearsĭid you know that concrete is the most marketed material in the world other than water? And that there’s about 50 gigatons of sand and gravel mined and incorporated in asphalt, primarily in concrete, every year? Concrete is actually one of the very few places where we can store massive amounts of CO 2. The crucial necessity of solving the climate crisis goes beyond everything else we’re dealing with today.Įvery year, fossil fuels and industry emit 40 Gigatons (40 thousand million tons) of carbon dioxide into the atmosphere globally.Īll climate modelers think we can put maybe another 500 gigatons into the atmosphere before things really get crazy. If we follow that mechanism, we could mitigate climate in a significant way, billions of tons.” – Brent Constantz, Ph.D. Quantum Quote: “The key to mitigating CO 2 and affecting climate change lies in governments’ abilities to use their procurement power to procure carbon sequestered materials at grand scales. ![]()
