Heirloom

Heirloom is a hybrid direct air capture (DAC) and carbon mineralization company that uses limestone, an abundant and cheap mineral, as a sponge to pull carbon from the atmosphere. While limestone’s natural carbon mineralization timeline can take years, Heirloom aims to accelerate this process to just three days, with a goal of removing a gigaton of excess carbon from the atmosphere.

Shashank previously worked at Square and has his Bachelors of Science from Cornell University.

“If you want to be removing billions of tons [of carbon], you need a sponge to remove that carbon that is incredibly abundant. There’s trillions of tons of limestone in the earth’s crust. I often want to be running to the rooftops and yelling to the world, ‘Hey, we’ve got this stuff that is incredibly abundant and cheap and scalable!’ And why wouldn’t we want to be scaling this thing as large as we possibly could?”
