Peabody to buy $15M stake in Calera

Peabody Energy said it plans to buy a $15 million equity interest in Calera Corp., which has proprietary technology that converts carbon dioxide into green building materials.

Los Gatos, Calif.-based Calera, led by Chief Executive Brent Constantz, recently completed a demonstration project near Moss Landing, Calif., which used the emissions stream from a natural gas-fueled power plant. The Calera technology mixes CO2 with water from a variety of sources, causing the minerals to bond and release as synthetic limestone.
