Cabot Corporation (NYSE:CBT) announced that it has entered into two new contracts to provide its DARCO(R) Hg family of activated carbon products to energy utilities with customers in Arkansas, Louisiana, Mississippi, Missouri and Texas. In order to meet stringent federal regulations for mercury emissions in the United States, Cabot expects to provide the utilities with approximately 25 million pounds of activated carbon over the next three years.

These agreements will provide a key material to the utilities as they reduce mercury emissions to comply with the U.S. Environmental Protection Agency’s (EPA) Mercury and Air Toxic Standards (MATS) rule. The MATS regulation requires that coal-fired power plants in the U.S. remove approximately 90 percent of mercury from their emissions by April 2015. Effective immediately, Cabot will supply DARCO Hg-H and DARCO Hg-LH powdered activated carbon across multiple sites to satisfy 100 percent of both utilities’ requirements for activated carbon.

Compliance with MATS is expected to boost demand for activated carbon by electric utilities. Based on numerous Department of Energy and EPA-sponsored tests and customer trials, Cabot’s DARCO Hg family of products have proven to be highly effective in achieving mercury removal levels compliant with MATS.

“We pride ourselves on being a technically advanced partner to our customers. Our proven expertise and patented DARCO technology delivers the optimal solution to meet our customers’ compliance needs,” said Bart Kalkstein, vice president and general manager, Global Emission Control Technologies, Cabot Purification Solutions. “With the approaching implementation of the EPA’s mercury removal standards, we expect that demand will continue to rise and we are in a unique position to ensure reliable supply of high-quality products.”

Cabot’s DARCO Hg family of products for mercury control has currently been selected for use in more than 75 units throughout the United States and Canada. The utilities chose Cabot products based on their proven ability to meet or exceed mercury removal levels compliant with MATS and their respective regulations. In addition, Cabot is the only activated carbon manufacturer with multiple manufacturing sites dedicated to this market in North America, providing customers with a consistent source of supply and supply chain reliability. Cabot offers a full range of activated carbon services including rental systems, carbon reactivation, bulk delivery and change-out, carbon evaluation, as well as technical service and support to help customers meet their specific purification needs.

In addition to its role as a technology leader in mercury removal from flue gas, Cabot Norit Activated Carbon is recognized as the world’s largest and most experienced producer of activated carbon, which is used to remove pollutants, contaminants and other impurities from water, air, food and beverages, pharmaceutical products and other liquids and gases in an efficient and cost-effective manner. Combined with Cabot’s technical expertise, the DARCO Hg family of products can help customers achieve the lowest total cost of mercury removal.
