Environmental and safety manager for TCPI, Nilo Yap, stated that – for the time being – the company prefers natural additives for its cement given the option [...] Sustainable energy is a major concern in many industries around the world today. Companies are trying to develop new ways to make their products and methods of operation more efficient and eco-friendly. For companies that rely heavily on the combustion of oil and other fossil fuels, this concern for energy has manifested itself into the research [...] Environmental Protection Agency Administrator Lisa Jackson yesterday announced that carbon dioxide endangers the public health under the Clean Air Act and is therefore subject to EPA regulation. USA Today (12/8, Vergano) reports that the EPA ruling gave “the Obama administration power to regulate smokestack and tailpipe emissions that feed global warming,” explaining that it “covers six [...] BGE has been hitting the pavement hard in recent weeks serving our customers and exploring opportunities, as a result, the blog has fallen a bit too silent.

This Tulsa World article includes some very positive statements about the Lafarge tire burning program at the Tulsa plant, and avoids the FUD that normally accompanies such an article (only to provide “balance” of course!) They even make a [...] It was about a year ago that I first heard about Calera, a mysterious company that claims to be able to make cement by reacting CO2 and seawater with some “magic pixie dust” to produce a cement like material. Their claims have been widely disputed and their secretive nature has not done much to help the [...] The 2009 Conference Program opened with a powerful speech made by Ed Sullivan, Chief Economist for the Portland Cement Association. (Sullivan, by the way, recently testified to Congress on the stimulus package and has received high praise for the accuracy of his predictions). 1.
