Peabody Energy Acquires Equity Interest in Calera Corporation

Summary

---

ST. LOUIS, March 22 /PRNewswire-FirstCall/ -- Peabody Energy today said it has reached an agreement to purchase a $15 million equity interest in Calera Corporation, which has proprietary technology that converts carbon dioxide (CO2) into green building materials. Every ton of Calera building material is expected to store as much as a half-ton of CO2.

The technology captures CO2 emissions from coal- or gas-fueled power facilities, cement plants and refineries, and converts it into solid carbonates that can be used as building materials in the form of aggregates or other cement-type materials. Because Calera's process removes minerals and other constituents from water, it also acts as a freshening system to produce fresh water, which can benefit areas of the world that need clean water.
