While U.S. power plants have considered petroleum coke or “petcoke” to be too dirty to burn, India, on the other hand, has been importing this coal by-product of tar sands refining for years. However, it may be seeing its last days in the country which has served as its biggest importer.
In the aftermath of an Associated Press investigation published on December 1, India's Petroleum and Natural Gas Minister Dharmendra Pradhan has said the country is formulating plans to phase out petcoke imports. The AP investigation, filed from New Delhi, revealed that citizens who live near petcoke refining facilities have come down with a range of air pollution-related illnesses in recent months and years.
The AP also points out that among the largest exporters of U.S. petcoke are Koch Industries subsidiary Koch Carbon and Oxbow Carbon, the latter of which is owned by the twin brother of David Koch, Bill Koch. The advocacy group Oil Change International referred to petcoke as “the coal hiding in the tar sands” in a 2013 report documenting the carbon footprint of petcoke production and combustion.
