As widely reported this week, the EPA has passed a long anticipated set of rules regulating the emission of mercury and other pollutants from cement plants. Reactions have been predictable: dire predictions that the regulations “can’t be met” with existing technologies for certain plants and claims of the billions of dollars the new regulations will cost the industry. Industry spokespersons [...] In 2009, industrialized nations across the world took serious steps toward reducing their carbon footprints and reducing emissions as compared to 1990 levels. The global average decrease of seven percent was fueled mainly by the economic crisis and its lack of energy demand. However, despite this heartening improvement, the Netherlands Environmental Assessment Agency (NEAA) has said [...] The European Union’s climate commissioner Connie Hedegaard is pushing to increase the 2020 emissions reduction goal from the current twenty percent to thirty percent. The heavy industries, including cement and steel, have lobbied the EU against such drastic cuts successfully in the past (ever since the United Nations talks in Copenhagen failed this previous December) on [...] One of the world’s most abundant organisms, algae, may be the solution to CO2 emissions for the cement industry. Two Ontario, Canada-based companies have developed a process in which carbon-eating algae is used to scrub exhaust gases of the greenhouse gas. St. Mary’s Cement (SMC), part of Votorantim, and Pond Biofuels have been working on the [...] In September 2009, a group of agencies and industry representatives (including the Cement Energy and CO2 Reduction Group and the US DOE) convened for a two-day conference to discuss reducing the carbon footprint of the US cement industry. The cement industry provides tens of thousands of jobs directly and indirectly, so government agencies are seeking to work with [...] Control Engineering reports that Cemex has been awarded the Energy Star Partner of the Year award for a second time. Cemex has been an Energy Star partner since 2004, and in 2009 saved more than 1.1. million MMBTU on energy, cutting an equivalent of 107,500 metric tons of CO2 emissions. In a time of economic stress, Cemex, [...] During this year alone, the cement industry is expected to spend approximately $3.5 billion to help control atmospheric emissions. By 2015, spending is predicted to rise to nearly $5 billion annually. Each region of the world is facing different challenges and taking different steps in order to meet increasing emission standards. In the United States, most of [...] Members of the Portland Cement Association (PCA), lobbying on behalf of the cement industry as a whole, are pushing the Environmental Protection Agency (EPA) to not add new regulations limiting the amount of mercury and other pollutants emitted from cement plants. Their argument is based on the subsequent rise in production costs which would seriously hamper [...] Calera is back in the news with it’s CO2 eating cement made by reacting stack emissions with a magnesium salt rich water solution. The San Francisco Chronical is reporting on his pilot plant and California and the fact that Constantz has managed to get himself invited to speak about Calera to the World of Concrete trade [...] Lehigh Cement will begin voluntarily testing of activated carbon injection technology, commonly used to reduce mercury at power plants, to reduce the emissions at its plant in Union Bridge Maryland. The mercury will be permanently sequestered in the final product. Lehigh believes it can meet the EPA proposal for 2013 mercury levels without negatively impacting the quality of [...] |
