Among other emissions, Carbon dioxide is a headache for many cement producers. Finding the right balance between environmental-responsibility and financial-stability is difficult. For industrial plants shifting towards carbon capture and sequestration (CCS), economic performance suffers due to the high cost of installing and running the necessary equipment. However, a way of offsetting those costs is now in development at Sandia [...] Aķcansa Cement, a joint venture of HeidelbergCement and Sabanci Holding, recently announced the installation of a $24 million waste heat recovery unit at their Çannakale, Turkey, plant. Aķcansa, which produces 6.5 tonnes of clinker and 9 million tonnes of cement annually in three plants within Turkey, is a major producer of both cement and ready-mixed concretes. The [...] Is relief is on the horizon for the cement industry? Recently, two representatives introduced a bill titled “Cement Sector Regulatory Relief Act of 2011.” If passed, this legislation will require the Environmental Protection Agency (EPA) to re-propose three rules aimed at the portland cement industry. These rules were targeting the solid waste incineration initiatives started by [...] With America’s infrastructure crumbling and the economy still struggling to recover from its nosedive, a game of passing the buck has begun. The federal government has no money to foot the enormous bill of rebuilding and expanding roads, bridges, water and waste treatments systems, etc. Just recently a group of senators has drafted a bill that [...] On June 2, the Environmental Protection Agency unveiled new sulfur dioxide (SO2) primary national ambient air quality standards (NAAQS). The EPA’s main reason for revoking the former standards is the public health risk posed by sulfur oxides, which SO2 is a part. They claim that sulfur oxides react with compounds in the atmosphere to form particulates [...] With almost 900 ash-containing landfills nationwide, the proper disposal of coal ash was a problem that could be avoided no longer. Early last week, the Environmental Protection Agency finally announced a new proposed set of regulations on coal ash, the first time this by product is being nationally regulated. The main concern with this coal power plant after [...] Senators John Kerry (D-Ma), Lindsey Graham (R-SC), and Joseph Liebermann (I-CT) have been working on a sweeping climate change bill for months and are expected to reveal the bill in session on Monday, April 26. The senators have been pulled in twenty different directions by varied lobbyist groups, industry, environmental activists, and fellow colleagues on the [...] Michael Rock, an economics professor at Bryn Mawr College, held a lecture this past week concerning America’s lack of continued green technology development. He fears that we are on the way to losing our place as the forerunner of this industry just as we did in the automobile industry. Daniel Weiss, director of a DC-based climate [...] The Japanese have been trying to implement a method of converting refuse organic waste into usable fuel for some time now, but have encountered formidable barriers in their path. Their refuse-derived fuel (RDF) is produced from raw garbage, an adhesive, and lime in pellet form. However, the heat output of the RDF is very low compared [...] EPA administrator Lisa Jackson announced Monday that the agency would not push through regulations against large greenhouse gas emitters until 2011. Also, Ms. Jackson announced that the agency would raise the threshold for the Clean Air Act on regulating carbon dioxide emissions. The delay comes after multiple groups, including eight Senate Democrats, expressed concern on the potential [...] |
