			<content:encoded><![CDATA[<p>2009 was year where cement industry news was really dominated by three factors:  the economy, the Chinese, and the environment.  Here are some of the stories we at BGE believe were the most important of the year:</p>
<p><strong>It&#8217;s the economy, stupid</strong> &#8211; The economic collapse and its effect on the cement industry may have started in ernest in 2008, but it really hit high gear in 2009.  Cement producers in North America and around the developed world responded with cut backs in capital projects, plant closures (some temporary, some less so), layoffs and other cost saving measures.  Producers in North America and Europe continue to postpone investments, preserve cash, and fend off price erosion of their product.  The poster child for the pain of a vanishing credit market had to be Cemex.  As the fastest growing member of the global cement producers, funded mostly on gigantic lines of credit, they found themselves on the verge of insolvency, sold off a number of strategic assets, and to admirably survive as they managed to renegotiate billions in credit.</p>
<p><strong>Sinoma International becomes the world&#8217;s largest OEM</strong> &#8211; OEM&#8217;s responded with traditional &#8220;retrenching&#8221; moves, cost cutting and layoffs.  Shoveling expertise into the street with abandon, a trend that is expected to continue.  Those with a small piece of a large pie now found themselves with a small piece of a much smaller pie.  Expect at least one of the traditional Euro-American suppliers to fail in 2010.  Of course, not all the suppliers played defense.  The Chinese OEM&#8217;s, Sinoma in particular, took advantage of the increased price sensitivity to become, for the first time in history, the largest supplier of cement equipment in terms of new production capacity OUTSIDE China.  In fact, Sinoma sold just under 50% of the capacity sold outside China in 2009, pushing FLSmidth out of the #1 spot it had held for decades and forever changing the competitive landscape of cement equipment supply.</p>
<p><strong>Big Brother is watching</strong> &#8211; The environment and the increasingly large specter of regulation has to be one of the biggest stories of 2009.  Environmental sessions were sharply in focus at the IEEE/PCA conference.  The EPA made noise about Mercury and they made noise about CO2.  Eventually they classified CO2 as a hazardous substance, thereby giving themselves the power to regulate it.  New regulations have also been proposed for Mercury and will be a reality sooner rather than later.  We have <a href="http://blog.bridgegapengineering.com/tag/environmental">frequently</a> <a href="http://blog.bridgegapengineering.com/tag/epa">reported</a> on the various environmental issues in this blog as we see it as a major force in the market for years to come.</p>
<p><strong>Modernization of capacity</strong> &#8211; 2009 certainly wasn&#8217;t all bad news for the cement industry.  Developing markets continued to show growth and reinforce the long term trends in demand.  Additionally, many of the modern, high capacity plants ordered in the last boom came on line in 2009, thus &#8220;modernizing the fleet&#8221; and providing the ability to produce more cement at a lower cost with less energy and environmental impact.  Holcim&#8217;s shining star, the 12,000 mtpd Ste. Genevieve plant designed by FLSmidth, came on line in July and quickly met and exceeded production and environmental targets.  This facility will help to assure the future of cement manufacturing in the difficult labor and regulatory North American market environment and provide a model for cement plant design going forward.</p>

			<content:encoded><![CDATA[<p>The Financial Times <a href="http://bit.ly/7JjZtb">reports</a> today that the major cement manufacturers expect cement demand in Europe and The US to be 30% and 44% (respectively) lower than in 2007. A squeeze on infrastructure projects, thanks to exploding government debts and tightening of spending is primarily to blame, they said.</p>
<p>The major producers are clearly focused on developing markets where demand is more organically and necessity driven. They don&#8217;t expect the situation to turn in the developed markets until 2012. Even so, given the time to market for a new production line and the spectre of impending CO2 regulations and their potential impact on capacity, we believe that regions in North America can expect to see cement shortages and high prices in the coming years as a result of the major producers business focus being elsewhere.</p>
<p>This is one of the consequences of the industry consolidation that has taken place over the last decade and a half. As the local independent producers have been absorbed by the global producers, the business focus has shifted from one of defining and fulfilling local market needs to one of looking at complete continents as a single market. This is not necessarily good or bad, it just <em>is</em>. The global producers will be investing their available capital in markets they see as having the largest short term potential. The result is that near term opportunities may be created in the Americas and Europe for those who are willing to take a risk and gain first mover advantage. Demand will continue to grow in these markets, and in some cases that demand might be extremely localized.</p>

			<content:encoded><![CDATA[<p>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. We won&#8217;t let that become a habit (well, serving customers and exploring opportunities are habits we intend to keep). Nevertheless, interesting news has not rested!</p>
<p>Through <a href="http://www.tonic.com/article/concrete-evidence-better-cement/">an article on tonic today</a>, we found a <a href="http://www.guardian.co.uk/technology/2009/nov/04/liquid-granite-hunt-carbon-neutral">story on The Guardian</a> about &#8220;Liquid Granite&#8221;, a so called carbon neutral cement substitute developed by <a style="border-collapse: collapse; background-repeat: no-repeat; color: #005689; text-decoration: underline; padding: 0px; margin: 0px;" title="Prof Pal Mangat of Sheffield Hallam University" href="http://www.shu.ac.uk/research/meri/profiles/p_mangat.html">Prof Pal Mangat of Sheffield Hallam University</a>. As is normal, details are sketchy. Professor Mangat says only that Liquid Granite is made from an inorganic powder, 30-70% of which is recycled industrial waste materials. Using the same aggregates as normal concrete, it could be used anywhere cement is but with a fraction of the carbon footprint.</p>
<p>The same article points to an <a href="http://www.guardian.co.uk/environment/2008/dec/31/cement-carbon-emissions">earlier story</a> we have mentioned previously about a carbon <em>negative</em> cement developed by Novacem which, in theory, absorbs CO2 from the atmosphere at a greater fraction than is released during manufacture. The tonic article also mentions our favorite press release pixie dust company, Calera, who manages to <a href="http://www.reuters.com/article/gwmEnergy/idUS189904988420091104">stay</a> in <a href="http://online.wsj.com/article/SB10001424052748704746304574506030258504644.html?mod=article-outset-box">the</a> <a href="http://miller-mccune.com/science_environment/concrete-solutions-for-climate-change-1551">news</a> despite no real signs of a marketable product yet (and much scientific skepticism).</p>
<p>Finally (phew) Recycling Product News has a feature not cement specific, but about how much time and effort is being put into research for Carbon Capture and Storage (CCS) without considering what to do with all that stored CO2. Many companies are sprouting up around methods to turn captured CO2 into valuable products such as formic acid, algae biofuel, methanol, etc. All very real processes with very real commercial results.</p>
<p>BGE has the skills and knowledge required to integrate CCS and CO2 conversion technologies into cement production facilities. Contact us to discuss the possibilities. The future is now.</p>

			<content:encoded><![CDATA[<p>Researchers at MIT <a href="http://www.sciencedaily.com/releases/2009/09/090909141639.htm">have discovered something</a> that has eluded science for all of history. In research funded by Portuguese cement producer Cimpor, MIT has finally modeled the crystalline structure of cement hydrate. Yes, in spite of cement being the most widely used manmade building material in the world, no one really knew how it worked, at least not on a molecular level!</p>
<p>What does such a discovery mean? In some ways it can be compared to the unravelling of the human genome. The potential applications of the knowledge are widespread. For starters, understanding the structure of cement will make it easier to find ways to modify its properties. Inevitably it will also ease the path to methods of production with lower energy consumption and emissions.</p>
<p>MIT doesn&#8217;t claim to have completely defined the structure, they call their model a &#8220;first step toward a consistent model of the molecular structure of cement hydrate&#8221;. Clearly work remains to be done, but there is no doubt that this knowledge will ultimately change the industry.</p>

			<content:encoded><![CDATA[<p><a href="http://www.calera.biz/">Calera</a> is back in the news with it&#8217;s CO2 eating cement made by reacting stack emissions with a magnesium salt rich water solution. <a href="http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2008/09/02/MNGD12936I.DTL&amp;">The San Francisco Chronical is reporting</a> on his pilot plant and California and the fact that Constantz has managed to get himself invited to speak about Calera to the <a href="http://www.worldofconcrete.com/ind/woc-homepage.aspx">World of Concrete</a> trade show in Las Vegas next February. They quote a spokesman from The Sierra Club declaring the technology &#8220;a game changer&#8221;.</p>
<p>We wrote about Calera before in our &#8220;<a href="http://blog.bridgegapengineering.com/magic-pixie-dust">Magic Pixie Dust</a>&#8221; post, a term taken from one of the critics of the technology. At BGE we don&#8217;t know if Calera is engaging in science, magic or fraud but we do know this kind of publicity and attention is &#8220;game changing&#8221; at the end of the day.</p>
<p>This is mainstream press in a large, environmentally sensitive market. Whatever it is that Calera is producing, game changing or not, you can bet the political pressure will be turned up to legitimize it. Further, every article about Calera &#8220;educates&#8221; the public further about the CO2 costs of cement, and turns up the heat on the government to mandate cleaner production.</p>
<p>Cement is certainly one of the most important building materials in the world and is critical to continued economic development, however cement is going to have a CO2 image problem in a hurry. The green benefits of concrete construction need to be better understood by the public and better articulated by the industry.In addition, the industry has to show that it is genuinely interested in investing in technology that will reduce or sequester CO2 emissions, and that it is not content to wait until it is regulated to do so.</p>
<p>Technology is available <span style="text-decoration: underline;">today</span> to reduce plant emissions, without resorting to magic. BGE can help every producers find the right technologies to apply to their facilities to make a <span style="text-decoration: underline;">real</span> difference.</p>

		<description><![CDATA[This posting discusses corporate decision rights versus plant decision rights - where should the line be drawn? [...]]]></description>
			<content:encoded><![CDATA[<p class="MsoNormal" style="margin: 0in 0in 0pt;">Lately, national politics seems dominated by discussions about the expansion of the federal government. Congressional proponents &amp; opponents of such growth probably have a mix of benevolent and malevolent intentions &#8211; but evaluating their intent is misguided (as we all know what the road to hell is paved with!) When a new topic gets on the radar screen of congress, the first question that should be asked is: can the federal government realistically manage Idea X effectively? Or is this better handled by state &amp; local communities (if not individuals)?</p>
<p>Similar ‘decision-rights&#8217; questions should be asked inside our companies, especially in the field of RAM (Reliability &amp; Maintenance). A corporate office is well-suited to address some topics; other times, it is just getting in the way. Where should the line be drawn?</p>
<p>One legitimate area for centralization is equipment naming conventions. Standardizing this across multiple plants can seem tedious and frustrating in the short-term &#8211; every plant already has a language for referring to equipment that is known and understood by the workers. But the enterprise also has a need to understand &amp; address systemic problems. Doing so requires a common language. Without that consistency, every equipment name has to be time-consumingly re-translated into a common language, which is an extremely error-prone exercise. The result can be bad data, confused communication, and poor decisions that impact the entire enterprise.</p>
<p>However, there are other times when a corporate entity inappropriately exerts its influence. For example, it may be tempting to have a reliability engineer write preventive maintenance (PM) inspections for plant equipment and then upload that inspection into each plant&#8217;s Computerized Maintenance Management System (CMMS). But even if this is well-intended, it rarely works.</p>
<p>First of all, the most effective inspections are ones where the plant feels a sense of ownership. If the PM is dictated from afar, it may be greeted by the plant with irritation &amp; passive/aggressive compliance. Secondly, PM frequencies will change over time, depending on equipment age. Unless the plants are exactly the same, the one-size-fits-all approach won&#8217;t always make sense. Third, inspections need to be logically clumped into common routes so they become schedulable events. This is very difficult to do from afar and may legitimately vary from plant to plant. Finally, if the plant cannot refine a PM without going through a maze of red tape, the inspection will be ignored or pencil-whipped. PM tweaks should be commonplace and easy to accomplish.</p>
<p>Here are some other examples of this dynamic:</p>

			<content:encoded><![CDATA[<p>Have you ever heard the expression “Life’s how it <strong><em>is</em></strong>, not how it ought to be?”</p>
<p>An enterprise that wants to implement a standard reliability strategy across multiple sites must confront the implication of this statement.</p>
<p>Most mining enterprises do not have cookie-cutter plants or facilities. The locations will vary in age of equipment and workers. The quality of regional raw materials may be different. Plants near metropolitan centers may have high turnover while those in small towns may be staffed with “lifers.” Cultures can be different. Some plants are union free and historically have had good relations between hourly and management. Others have histories filled with mistrust and arbitrary rule enforcement.</p>
<p>Non-standard plant circumstances force the enterprise to find the right balance between centralization and decentralization. When do you standardize in the name of the enterprise and when must decision-making be left to local management?</p>
<p>Before some of these balances can be discovered, an enterprise must face the truth of “how it is.” Confronting the brutal facts of reality can be more difficult than it sounds.</p>
<p>If a company has spent millions of dollars on a Computerized Maintenance Management System (CMMS), it may not be pleasant to find out that most of the collected data is jumbled. If hundreds of thousands of dollars has been spent on vibration equipment &amp; training, it may be painful to learn that the well-intentioned but part-time vibration specialist did not develop sophisticated time waveform analysis capabilities. If a loyal, friendly, experienced worker has been functioning as a planner for years, it’s hard to confront the fact his actual contribution is clerical in nature – and clerical contributions do not yield the productivity gains of planners who actually plan.</p>
<p>So – how does an enterprise face these brutal facts?</p>
<p>(1) <strong>Differentiate <em>process </em>from <em>people</em></strong>. Remember that workers – especially long-time employees – are usually well intentioned. Organizations must consciously create work processes that focus on productivity &amp; proactivity; these things do not naturally emerge without guidance and direction. A planner who focuses on non-productive behaviors is not necessarily a bad employee. The proper routines, tasks, and rules may not have been properly defined for him. When you view your organization through a process lens rather than a people lens, it is easier communicate without your employees feeling defensive or attacked.</p>
<p>(2) <strong>Hire a consulting firm</strong>. The reality is – the objective, third party gaze can often see things more clearly. Consultants aren’t smarter. They aren’t more knowledgeable about the operation of the plant. But if they are experienced, they are able to quickly zoom in on things that are indicative of a healthy reliability system. (Can the plant easily print a sorted list of Ready to Schedule work? Are the Preventive Maintenance tasks specifically defined?) As outsiders, consultants also have the luxury of remaining emotionally detached from existing relationship &amp; histories between people &amp; departments. This clinical disposition means they won’t be as easily swayed by charisma, earnestness, anger, or old wounds that won’t heal. Good consultants know they cannot add value to an enterprise if they are simply telling their clients what they may want to hear – or if they are ignoring the white elephant in the room. They know that a reliability initiative has to be built on a foundation of transparency and a clear assessment of current conditions.</p>
<p>(3) <strong>Establish norms around <em>honest</em> and <em>respectful </em>communication</strong>. Respect is important, as snippy exhortations about “ugly babies” and “garbage-in, garbage-out” data will get old real fast if the feedback has a tattle-tale quality. Stick to observations, not judgments about personalities. Accumulate multiple observations before drawing firm conclusions. Don’t just ask about problems that have occurred – ask about the frequency of those problems. Are parts/materials really never available when jobs are assigned, or did this only happen one time, three years ago? And never, ever retaliate against someone after you have given them permission to speak freely. If you do, you will never hear another honest observation again.</p>
<p>Reliability is a data driven field. It is a science. It has objective metrics. Although it may fail in the short-term (a vibration test may fail to identify a loose bolt) – over time, consistent application of reliability concepts produce huge dollar savings. Sycophantic relationships will destroy reliability. Transparent, data-driven decision making must be the norm; otherwise, reliability is just a meaningless label to smack onto old habits. But before an enterprise can begin its reliability journey, it must have an honest assessment of where it is at.</p>
<p>What are other ways an organization can get a good assessment of its current reliability situation?</p>

			<content:encoded><![CDATA[<p>Michael Mandel has <a href="http://www.businessweek.com/magazine/content/09_24/b4135000953288.htm?campaign_id=rss_daily">an interesting article</a> at BusinessWeek where he speculates that part of the blame for the current economic slump can be placed on a <em>failure</em> to innovate over the last decade. This is somewhat shocking at first, given all the hype innovation has received in the business world and the general press. On the surface the technological revolution has been greater then the industrial revolution&#8230;until you look at the actual contributions to business and society.</p>
<p>True, technology is moving forward at leaps and bounds and it seems new and promising research is announced daily that will save the environment/cure cancer/prevent bad breath/insert your favorite cause, but much of it has proven devilishly difficult to bring to full realization.</p>
<p>The argument continues that this failure of innovation to deliver on promise caused debt driven growth based on a fantasy vision of the future. I can buy into this pretty easily for biotech, energy, technology and a few other areas, but I&#8217;m still looking for a connection to the cement boom. The argument could be made that cement manufacturing as an overall process has been in the slow lane for a long time. It&#8217;s a low risk kind of business after all. Innovation has been primarily focused on incremental improvements in production, quality, reliability, environmental compliance, and cost. Very few producers are really trying to do anything <em>differently</em>, just better, and the OEM&#8217;s are simply meeting the demands of the market.</p>
<p>Tell us what you think. How did the innovation gap figure into the cement production investment bubble? Should producers be investing in completely new approaches to making cement? &#8230; or is there simply an enormous amount of low hanging fruit readily available in the day-to-day operation of a cement plant &#8211; yet to be tapped? </p>
<p>Trying to decide whether to innovate <em>or </em>survive in tumultuous times? Asking the question misses the point, the only answer is to do both! But how? Over at <a href="http://harvardbusiness.org/">Harvard Business Publishing</a>, they have started to publish a <a href="http://blogs.harvardbusiness.org/anthony/2009/06/seize_the_silver_lining_a_chec.html?cm_re=homepage-051309-_-body-middle-tert-_-voices">series of articles</a> with some of the key points from a brand new book, <a href="http://www.amazon.com/Silver-Lining-Guide-Innovating-Downturn/dp/1422139018/">The Silver Lining: An innovation Playbook for Uncertain Times</a>. The summaries sound promising and the book is definitely on my near term reading list. Read the articles in the links and download a free copy of the first chapter and it will probably be on yours as well.</p>

			<content:encoded><![CDATA[<p>It was about a year ago that I first heard about <a href="http://www.calera.biz/">Calera</a>, a mysterious company that claims to be able to make cement by reacting CO2 and seawater with some &#8220;magic pixie dust&#8221; to produce a cement like material. Their claims have been widely disputed and their secretive nature has not done much to help the cause, but for some reason they seem to be getting a lot of press lately. Green building material articles from <a href="http://www.reuters.com/article/earth2Tech/idUS342017807320090605">Reuters</a>, the <a href="http://www.contracostatimes.com/localnews/ci_12486435">Contra Costa Times</a> and other sources have been giving them ink. Also, the <a href="http://www.greentechmedia.com/articles/read/more-clues-in-calera-cement-controversy/">Greentech blog</a> has been following the story and presenting scientific opinion for some time.</p>
<p>I fall into the camp of skeptical but seriously interested on this one. Even if Calera can only produce a cement additive it will be a breakthrough in sequestration technology. Cement can already be (and is) considered a green building material by a number of measures, and carbon capture could really boost the cause. Notably <a href="http://www.calstarcement.com/">other commercial enterprises</a> are looking to join the fray with this mystery technology.</p>
<p>What do you think? Fish oil or a greenhouse gas breakthrough? Let us know in the comments.</p>

			<content:encoded><![CDATA[<p>The build-up related to another “Cooler Wars” panel discussion for this week’s IEEE Conference Participants turned out to be <em>very anticlimactic</em>. Following the panel discussion, nearly all of the participants polled concluded that there is very little in the way of technology that currently differentiate the major OEMs (<a href="http://www.khdhumboldt.com/" target="_blank">KHD</a>, <a href="http://www.polysius.com/" target="_blank">Polysius</a>, FLSmidth, <a href="http://www.claudiuspeters.com/" target="_blank">Claudius Peters</a>) when it comes to clinker coolers:<br />
• All current OEM designs (except <a href="http://www.ikn.eu/cms/" target="_blank">IKN</a>) are offering a 3rd Generation Cooler based on FLSmidth’s revolutionary Cross-Bar Cooler which was developed more than 12 years ago (having separated the conveying function from the cooling function).<br />
• In the case of IKN, this seems more like a lack of commitment to new R&amp;D than any perceived advantages for a 2nd Generation cooler compared to the other OEM’s 3rd Generation designs.</p>
<p>For cement producers, they really can’t go wrong with any of the new 3rd Generation Coolers:<br />
• Cooler run-time has improved dramatically since the mid-1990s.<br />
• Heat recuperation has increased substantially.<br />
• Low maintenance costs are now verifiable.<br />
KHD and FLSmidth may hold a slight advantage because of their patented airflow control valves for each “grate plate” in the cooler.</p>
<p><em>Here’s our report of what each OEM had to say:</em></p>
<p>1. <strong>KHD Pyro Floor Cooler, presented by Thomas Binninger:<br />
</strong>a.  Only 10 coolers in operation.  Excellent presentation.    Nothing new except published process results which show air consumption as low as 1.6 Nm3/kg to achieve 70 C above ambient temperature clinker.</p>
<p><strong>2. Polysius Track Cooler, presented by Dr. Uwe Maas:<br />
</strong>a. About 65 coolers in operation.<br />
b. New static inlet section (zero step discharge) for improved cooling and maintenance.<br />
c. Verifiable low maintenance costs.<br />
d. Probably the most authentic of all speakers (keeping promises regarding wear life of components and working to make it even better):<br />
i. Informed the audience not to confuse expected wear results (anticipated) with guaranteed wear results (warranty).<br />
e. Unfortunately, Polysius again failed to present any verifiable cooling performance data (probably owing to zone aeration compared to airflow control valves).<br />
f. Static grate does not prevent snowman, but removal of snowman becomes easier due to the continuous incline without steps.<br />
g. 200 to 225 mm stroke length.<br />
<strong>3. FLSmidth Cross-Bar Cooler with ABC Inlet, presented by Steven Miller<br />
</strong>a. Nearly 200 coolers in operation.<br />
b. Snowman prevention systems with variable blast area, frequency, and intensity.<br />
c. FLS is willing to guarantee “no down-time” due to snowman formations.<br />
d. Most credible presentation based on 12+ years of experience and over 200 coolers sold. However, missed an opportunity to really drive this point home (e.g. imitation is the highest form of flattery).<br />
e. Case Study: Standard Cooler Loss decrease from 104 to 96 kcal/kg clinker.o<br />
f. Guarantee 2-3 years for wear components and 5 years for grate “plates”.<br />
g. 180 to 200 mm stroke length.<br />
<strong>4. CPAG Eta Cooler, presented by Andre Vos:<br />
</strong>a. 16 coolers in operation.<br />
b. Self-protected aeration lanes (93% of grate is protected).<br />
c. Unfortunately, the grate requires pre-charging with sieved gravel because clinker has been shown to breakdown in this cooler over time adding pressure drop across the grate.<br />
i. Reportedly, this was ‘discovered’ by Holcim.<br />
d. Zone aeration (like Polysius) which at least in theory is less effective than airflow valves (KHD and FLS).<br />
e. If a hydraulic cylinder fails, it is possible for the cooler to continue operating with “one lane down”.<br />
f. Run factor of up to 99.95% for cooler alone.<br />
g. Longest and variable stroke length to allow for increased retention time.<br />
h. 200 to 300 mm stroke length.<br />
<strong>5. IKN Cooler, presented by Christoph Lange:<br />
</strong>a. 96 coolers in operation.<br />
b. Lowest drive power (simple physics – no friction between ‘lanes’).<br />
c. 120 to 125 mm stroke length.</p>
