The accusations of cartelisation, if any, are totally incorrect and ill-founded



Vinita Singhania, Managing Director, JK Lakshmi Cement Ltd, and President, Cement Manufacturers’ Association (CMA) in an e-interview with Indian Cement Review, explains her priorities, defends accusations and puts forth her suggestions for the growth of Indian cement industry.

Now that the Budget 2011-12 has been announced, what are your priorities for the Indian cement industry?
My main priority for the cement industry is to arrange/mobilise adequate raw materials and infrastructure so that the industry can grow at the required rate to meet the emerging demand of the nation in the next one decade. Indian cement industry today faces acute shortage of fuel for production as well as for its power requirement, wagon for its movement of cement and more importantly, bulk handling infrastructure at the cement unloading/consumption points. Further, since the Budget has not addressed the long pending concern of the industry with respect to the high taxation burden, the priority to sensitise and convince the authorities about the same remains an important item on the Industry’s agenda.

What has the Budget badly missed out, which would have propelled the industry to greater heights?
As mentioned earlier, the issue of high taxation on cement industry which results in high cost of cement to the end-consumers needs to be looked at by the government afresh, recognising that cement is an essential input for the country’s infrastructure development as also for common man’s housing requirement.

The Budget does not incentivise efficient working in the cement industry atleast. Neither it has encouraged the modern method of construction/products like RMC, AAC blocks etc, which are not only environment-friendly but if which encouraged can reduce the load on the country’s resources and infrastructure. Instead of any incentive products like fly ash, slag, RMC are now being subjected to excise rate of one per cent. With imaginative use of taxation on these products their consumption could have been encouraged.

What is your opinion on the reduction in import duty on pet coke and gypsum? What would be its impact on production cost?
Reduction in import duty on pet coke and gypsum is a positive move though the reduction is still only half way meeting the industry’s requirement which faces an anomaly of cement being imported at zero per cent import duty while the import of its raw material was being subject to 5 per cent import duty which has been reduced to 2.5 per cent in the Budget. It can possibly impact the production cost by about one per cent to those units who are dependent on imported coal or pet coke and who are situated closer to the ports. The rest of the cement plants which form a major chunk remain unaffected.

The government has restructured the excise duty by bringing in composite rates having an ad valorem and specific component. What would be its impact on the cement price?
The dual system of excise on cement is now prevalent for the fifth year. The bigger question is not that one of ad valorem vs specific rate. The issue is that since in a commodity like cement post manufacturing expenses are very high, notably that of freight, the excise duty if charged on ad valorem rate, should also have a provision for abatement on such post manufacturing expenses. In fact, the government has been providing abatement to many industries, including white cement. The cement (grey) industry, however, continues to remain deprived of this abatement causing hardship to the industry.

The surcharge limit on corporate tax has been brought down to 5 per cent from 7.5 per cent and the minimum alternate tax (MAT) has been increased to 18.5 per cent from the existing 18 per cent. What would be its impact on the industry?
The reduction of surcharge on corporate tax by 2.5 per cent and increase in MAT rate from 18 to 18.5 per cent has resulted in increase in overall MAT rate by 0.08 per cent and decrease in corporate tax by 0.77 per cent. This has widened the gap by 0.85 per cent in normal corporate tax and MAT rate.

The resultant gap between the normal tax and MAT will negatively impact the capital investments as also the cash flows of companies on MAT.

There is always an accusation of cartelisation in the cement industry, which leads to artificial hike in price. Your comments on this allegation.
The accusations of cartelisation, if any, are totally incorrect and ill-founded.

On one hand, a price hike is announced every alternate week while on the other, the industry faces a serious under-utilisation of capacity. Can you explain this anomaly?
It would be incorrect to say that price hikes are announced every alternate week. For instance, in the area where our company JK Lakshmi Cement operates, we have not seen any price increase from March 2010 to January 2011 though, yes, we did see price declining a number of times. The industry normally faces this dilemma that whenever the prices decline the capacity utilisation also declines. This is understandable as cement prices are a direct off-shoot of demand and supply and whenever the supply increases on account of new capacity creations the overall capacity utilisation falls if the demand is not able to keep pace with the addition in the capacities.

Since the capacity is under-utilised, are there any plans to bolster the export?
The exports this year are at about the same level as last year. Indian cement industry is a marginal player in the international cement trade on account of its high inland cost of transportation. Also in the recent times consequent to the recession of 2008-09 the international demand for cement continues to be at low ebb. The Indian cement industry, therefore, has been finding it difficult to even maintain its previous level of exports.

Coal being the main fuel for the industry, its availability is depleting at a faster rate. How the use of alternate fuel can be encouraged?
Cement industry has been experimenting with alternate fuel for last many years now. Many cement plants in the country, including ours, have taken lead in working with alternate fuel like pet coke, lignite, agricultural waste, biomass, etc. One obvious way to encourage the use of alternate fuel would be to offer excise duty concession to the extent cement produced from the alternate fuel and if that alternate fuel is an industrial waste then the waste generating industry must compensate by some levy mechanism to promote utilisation of such industrial wastes.

With conventional source of energy getting dearer and environmentally risky, how is the industry embracing renewable source of energy?
One of the methods increasingly being resorted to by the cement industry is by greater usage of waste heat from the kilns and convert it into power.

How do you see the acceptance and evolution of blended cement in India?
By and large, the blended cement is now well accepted in many segments of the users. Surprisingly, the greater resistance comes from the public sector or government departments who for reasons best known to them continues to insist on usage of OPC. I feel there would have to be greater intervention by the government to ensure that usage of blended cement is made compulsory.

Cement companies are selling PPC at the same price as they would have sold OPC by adding flyash and hence there is more margin for cement companies in selling PPC. Your comments.
It would be incorrect to generalise that cement companies are selling PPC at the same price as that of OPC. In major parts of our markets, for instance, OPC commands a premium of Rs 15 to 20 a bag over PPC. In the markets where the price gaps are lower cement companies lose by selling more of OPC. In a way it is only appropriate that the cement companies should gain by manufacturing PPC and that is the only way the industrial waste like fly ash, slag, etc can be utilised in greater quantity.

RMC, being value-added product, is still in its nascent stage. What steps can be taken to encourage the use of RMC?
RMC off late in mature market is showing a trend of good growth. We expect this trend to continue and the use of RMC to grow in Tier II and III cities. The industry has to take certain steps to make RMC available, acceptable and affordable to the customers in Tier II and III cities.

Cement demand is driven by the housing market to the extent of 70 per cent and balance by infrastructure, etc. Given the pace of investment happening in infrastructure, do you foresee a shift in demand drivers?
To the best of our judgement, the consumption of cement in building construction is about 60-65 per cent and that would include building for housing as well as for commercial and infrastructure. Clearly, with greater emphasis on infrastructure development there would be gradually higher requirement by the infrastructure sector.

Many cement companies have reported loss in Q3. What are the factors affecting the companies? What remedial measures would you suggest in this regard?
Cement industry in the Q2 and Q3 has faced twin pressures, viz, falling cement prices and increasing cost of production. Fuels, both nationally and internationally, have seen a great upsurge in its prices thereby putting pressure on the cost of production while additional capacities which have created a situation of surplus, impacted the prices negatively.

Do you see mergers and acquisitions happening in near future? Is the cement industry ready for consolidation?
The current level of valuations do not make mergers and acquisitions attractive as the cost of acquiring capacity is higher than the cost of creating new capacity. In the past mergers and acquisitions have taken place as many MNCs who were wanting to establish themselves/or expand in India paid premiums. In immediate future with the current level of valuations I do not see much activity on this front but there could be surprises, I can’t be sure.

Stud technology has proven to be a boon for the industry




Ashok Kumar Dembla, President and Managing Director, KHD Humboldt Wedag India, discusses the advancements in grinding solutions that focus on low energy consumption, dust free circuits and low maintenance.

Tell us about the role of your grinding solutions in the cement industry?
We all know that grinding constitutes about 65-70 per cent of electrical energy consumption of cement manufacturing. Any saving in grinding energy can be good for operating cost reduction. Also, energy cost is increasing with time, therefore cement manufacturing companies are looking for new technologies for low electrical energy consumption. In the past few years, KHD has worked extensively in the field of grinding to reduce electrical energy consumption in the cement industry, which also helps in reduction in carbon footprints. We at KHD provide all kinds of grinding solutions be it raw material grinding, cement grinding or slag grinding.

How do you customise your grinding solutions to fit the requirements of distinct cement plants?
Based on the cement manufacturers requirement, we offer customised solutions for various grinding circuits. Every cement plant has specific requirements. Like some focus on low-cost solutions, some focus on energy efficiency whereas some focus on operational excellence. The input material hardness, moisture, abrasively, feed size and product requirement decide what solution is to be offered for achieving a cost effective and energy efficient solution. We have various sizes of roller presses, various types of roller surfaces, types of rollers and arrangement of roller presses in the circuit like roller press in semi-finish mode, roller press in finish mode, size of ball mill in semi-finish mode, location of static separator in process circuit, etc. So, based on all the factors, we decide what is to be offered.

How do your grinding solutions help cement plants achieve energy efficiency?
Latest developments related to raw material grinding in finish grinding in roller press have paid dividends even for soft and medium to hard material. Hard raw materials are giving higher bonus factor in finish grinding roller press systems and cement manufacturers are getting 2-4 Kwh/t saving in electrical energy in raw material grinding itself by using this technology as compared to vertical mill technology. Typical circuit offered by KHD for raw materials grinding in ComFlex Grinding circuit has advantages to process raw materials with high moistures with incorporation of V-Separator below the roller press and use of hot gases to dry the raw materials.
With the focus of the industry towards WHR systems, roller press grinding has further received acceptance as it uses no water for bed stabilisation and uses minimum hot gases as compared to other contemporary technologies.
In case of cement grinding, two technologies are being accepted, either vertical roller mill or roller press in semi-finish or finish grinding. Roller press in finish grinding has the advantage of further saving of 3-4 Kwh/t as compared to semi-finish grinding and vertical mill technology. With more acceptance of blended cements like PPC, PSC and composite cements, roller press in finish grinding is accepted as advanced technology in cement grinding. Typical finish and semi-finish grinding circuits offered by KHD are very popular in the cement industry. which includes use of roller press alone or in combination of roller press and ball mill respectively.
In the case of slag grinding, acceptance of roller press in finish grinding is well recognised. It offers a distinct advantage of saving of about 6-7 Kwh/t as compared to the vertical roller mill at 4200 Blaine. The advantage comes due to the hardness of slag and pressure grinding in roller press instead of attrition and low pressure in vertical roller press. Moisture issue is also tackled with the problem of coating by incorporating a V-separator below the roller press.

Tell us about the role of separators in the grinding process? How do they help achieve cost efficiency?
The basic role of a separator is to separate the feed material entering into it after grinding into two products i.e., coarse and fine. While fine is normally the final product in case of dynamic separator and is intermediate product in case of V-Separator. Dynamic separators have also gone through various technological developments, and we are offering 4th generation high efficiency separators now-a-days. These separators offer sharp cut point and minimum bypass (particle below 3 microns). This leads to less recirculation of fines thus improving the availability of the system and in turn efficiency of the system. V-separator is an excellent pre-separator cum dryer (in case of wet material) which is used for pre-separating the roller press throughput before the second separation in a dynamic separator. Two stage separation in the roller press circuit makes it energy efficient and ensures proper product quality.

Materials used for the manufacturing of cement are evolving every day. How does your machinery adapt to this change at the cement plants?
With the trends more on low clinker to cement ratio, today the Indian cement industry is moving very fast toward this aspect. PSC, PPC, composite cements are going up the curve. The cement industry is well versed with the utilisation and manufacturing of blended cement. KHD is one of the key suppliers for providing energy efficient technologies viz roller press grinding for the production of blended cement.
It is estimated that decreasing the clinker ratio in production of cement contributes to nearly 37 per cent of targeted CO2 reduction. By promoting PPC and PSC cement in India, more than 85 per cent cement is produced as blended cement or composite cement (which has come into existence during the last 3-5 years). PPC allows 35 per cent fly-ash usage at present, whereas PSC allows 55 per cent to 65 per cent granulated slag in clinker. Increase of Pozzolana (fly-ash) usage in PPC, up to 45 per cent can reduce the carbon footprint further which has a permissible limit of up to 55 per cent in some European countries. Our roller presses are well versed to take care of all these materials smoothly.

What role does technology play in designing and executing your grinding circuit at the cement plants?
It’s mainly the technology that has promoted the roller press circuits for grinding over VRM technology. Our technology takes into consideration the lowest energy consumption, dust free circuits, nil water consumption, lower maintenance and more in terms of availability and reliability. So, all the systems are based on technology to address all these points. For example, roller press surface plays an important role regarding maintenance requirements. Stud surface of roller press can provide continuous availability of roller press for 4-5 years without any welding requirement. Welded surfaces also have less than half the requirement of welding as compared to VRM, which has the attrition principle of grinding in addition to pressure grinding.

What are the major challenges in curating and executing grinding solutions?
Over the years we have done intensive work in the field of grinding solutions. We don’t foresee any major challenge now as we have already achieved lower power consumption, dust free circuits, more reliability, environmentally friendly grinding. However, we are on the track of continuous improvements to even achieve better because we believe that nothing is impossible, and we are always bound to reach new heights. With use of blended cements and LC3 Cement in coming future in India we are expecting higher blain requirement in final product which may see some technological advances in secondary grinding i.e., ball mills may be replaced by special mills however roller press shall continue in semi-finish and finish grinding applications.

Tell us about the innovations by your organisation in the near future that the cement industry can look forward to.
At present, the focus is to use roller press in finish grinding to get maximum energy advantage as compared to ball mill grinding especially for blended cement. Apart from electrical energy, the focus is also on roller press surfaces, which has minimum wear and offers trouble and maintenance free operation. Stud technology has proven to be a boon for the industry. Tungsten Carbide Studs are fixed on the roller surface by pressing in pre-drilled rollers, which offers autogenous grinding and minimum wear. Life expected out of these roller surfaces varies from 25,000-40,000 hours of operations without any surface maintenance.
Apart from this, developments are focussed on optimising the process circuit for energy efficient and pollution free operation. Developments in actuated dosing gate for feeding material to roller press and online monitoring of roller press surface are also worth noticing. There shall also be developments related to use of digital technology to monitor the performance of these grinding systems, which can contribute towards optimised production and increased availability due to timely signals regarding maintenance requirements.

Waste Glass as Pozzolana




Dr SB Hegde, Professor, Jain University and Visiting Professor, Pennsylvania State University, United States of America, gives a detailed account of the use of waste glass as Pozzolana, a sustainable solution for cement production, in a two-part article.

The increasing demand for cement, coupled with growing environmental concerns, has led to a search for alternative materials that can reduce the carbon footprint of cement production. Waste glass, a significant environmental concern itself, has emerged as a promising alternative due to its pozzolanic properties.
This paper delves into the concept of utilising waste glass as a pozzolanic material in cement production, highlighting its benefits, challenges and potential for sustainable development based on the research and development work carried out by the author. This is part one of the study; part two will be featured in the consecutive issue of the magazine.

Generation and Availability of Waste Glass
On a global scale, this only amounts to a recycling rate of less than 35 per cent. Worldwide, around 130 million tonnes (Mta) of glass are currently produced annually.
India alone produces three million tonnes of glass waste annually, of which only 35 per cent is recovered, and the rest often ends up in landfills or down cycled into construction material aggregates. Glass is found in municipal solid waste (MSW), primarily in the form of containers such as beer and soft drink bottles; wine and liquor bottles; and bottles and jars for food, cosmetics and other products. India is one of the largest consumers of glass in the world, and as a result, it also generates a significant amount of waste glass. Waste glass, also known as cullet, can come from various sources such as bottles, jars, containers, windows and other glass products.
The availability and generation of waste glass in India depend on several factors, including population, consumption patterns, recycling infrastructure and waste management practices. Glass waste can be generated from residential households, commercial establishments and industries as well as construction and demolition activities. In recent years, there has been growing awareness about the importance of recycling glass waste in India. Recycling glass has several environmental benefits, such as reducing the consumption of raw materials, saving energy and reducing landfill waste.

Infrastructural requirement
To effectively use waste glass as a pozzolanic material in a cement plant, certain facilities and processes can be implemented. Here are some key facilities that can be created:

  1. Glass Sorting and Preprocessing: A facility for sorting and preprocessing waste glass is essential to segregate glass by colour and removing contaminants such as paper, plastics and metals. Crushing or grinding equipment can be used to reduce the glass to a suitable particle size.
  2. Glass Storage and Handling: Adequate storage facilities should be established to store the sorted and processed glass. It is important to protect the glass from moisture and other environmental factors that can affect its quality.
  3. Glass Dosing System: A dosing system should be set up to accurately measure and control the amount of waste glass being added to the cement production process. This can involve automated feeders or other equipment to ensure a consistent and controlled addition of glass.
  4. Glass Grinding or Milling Equipment: Depending on the desired fineness of the waste glass, a grinding or milling unit may be required to further reduce the particle size. This equipment can include ball mills, vertical roller mills, or specialised glass grinding mills.
  5. Blending and Mixing Facilities: Cement plants typically have blending and mixing facilities where various supplementary cementitious materials, including waste glass, can be combined with other raw materials. This ensures homogeneity and uniformity in the cement production process.
  6. Quality Control and Testing: Facilities for quality control and testing should be in place to assess the chemical and physical properties of the waste glass, as well as the performance of the cementitious mixtures incorporating the glass. This can include laboratory testing equipment and personnel trained in relevant testing methods.
    It’s important to note that the specific facilities required may vary depending on the scale of the cement plant and the volume of waste glass being processed. Detailed engineering studies and consultations in cement production and waste management can help determine the optimal design and layout of these facilities within a cement plant. Additionally, it is advisable to comply with relevant environmental regulations and obtain any necessary permits or approvals from statutory bodies in that particular country for handling and using waste glass within the cement plant.

The Fineness of Waste Glass
When waste glass is used as a supplementary cementitious material in cement production, it is important to consider the fineness or particle size distribution of the glass. The fineness of waste glass affects its reactivity and compatibility with
cement, which can impact the performance of the cementitious mixture.
The specific fineness requirements for waste glass can vary depending on the specific application, the type of cement being used, and the desired properties of the final concrete or mortar. However, in general, the waste glass particles should be finely ground to ensure effective pozzolanic or latent hydraulic reactions with the cement.
Here are some common guidelines for the fineness of waste glass used in cement:
Particle Size Distribution: The waste glass particles should have a range of sizes to ensure good packing and fill the voids between cement particles. A typical particle size distribution for waste glass in cement applications is similar to that of cement, with a majority of particles passing through a 325 mesh (45 microns) sieve.
Blaine Fineness: The Blaine fineness test is often used to measure the specific surface area of cementitious materials. The waste glass should generally have a Blaine fineness similar to or higher than that of cement. Typical values can range from 300 to 500 m²/kg or higher, depending on the application.
Grinding or Milling: Waste glass may require grinding or milling processes to achieve the desired fineness. The grinding method can vary depending on the available equipment and the specific glass composition. Ball mills, vertical roller mills or specialised glass grinding equipment can be used.
Gradation Control: It is important to control the gradation of waste glass during the grinding process. A well-controlled gradation can improve the flowability and workability of the cementitious mixture.
It is worth noting that the precise fineness requirements may vary depending on the specific standards, specifications, or guidelines established by statutory bodies of the particular country.

Attributes of Waste Glass as Pozzolana
Based on research and development investigations the following avenues are investigated for utilisation of waste glass.
Pozzolanic Properties of Waste Glass: Pozzolanic materials, when combined with calcium hydroxide in the presence of water, react to form cementitious compounds. Waste glass, rich in amorphous silica, exhibits excellent pozzolanic properties. Through a process called pozzolanic reaction, waste glass can contribute to the strength, durability, and chemical resistance of cementitious materials.
Environmental Benefits: Incorporating waste glass as a pozzolanic material in cement production offers significant environmental advantages. Firstly, it reduces the need for virgin raw materials such as limestone, thus conserving natural resources. Additionally, it mitigates the environmental impact associated with glass waste disposal, diverting it from landfills or incineration.
Improved Concrete Performance: The use of waste glass as a pozzolanic material enhances the performance of concrete. Due to its pozzolanic activity, waste glass reacts with calcium hydroxide in the cement matrix, resulting in denser and more durable concrete. This leads to improved mechanical strength, reduced permeability, and increased resistance to chemical attack.
Supplementary Cementitious Material: Waste glass can be used as a supplementary cementitious material (SCM) in cement production. When properly ground and processed, waste glass can replace a portion of cement without compromising the desired concrete properties. This substitution not only reduces cement consumption but also lowers the carbon dioxide emissions associated with cement production.
Sustainable Development and Circular Economy: Utilising waste glass as a pozzolanic material aligns with the principles of sustainable development and the circular economy. It promotes resource efficiency, reduces waste generation, and contributes to a more sustainable construction industry. The integration of waste glass into cement production presents opportunities for collaboration between cement manufacturers, waste management companies, and regulatory bodies to develop innovative and eco-friendly solutions.

Teijin’s initiatives towards carbon neutrality




Teijin Group provides innovative solutions for enhanced quality of life

As climate change has a large impact on the global society and economy, industry, governments and academia are making efforts to reduce environmental impact including greenhouse gas (GHG) emissions through energy conservation, green energy and lifecycle assessment (LCA).

As a people-focused company, the Teijin Group provides innovative solutions for enhanced quality of life and works to minimise any negative impact on the environment or society through its business activities. Teijin considers environmental management to refer to management that reduces the environmental impact over the entire product life cycle, including all processes from material procurement to production, product use and disposal.

With raised targets for reducing CO2 emissions, Teijin’s long-term environmental targets have been adapted to an ambitious level of 30% reduction. With a further target of reducing the portion of emissions that accounts for over two-thirds of the overall supply chain emissions by 15%. Establishing achievable targets while also being ambitious has been key for us in leading the way to a carbon-neutral future. The Teijin Group’s targets for GHG emissions are now officially validated as Science Based Targets (SBT) as the first Japanese chemical manufacturer. The objective of SBT is to help achieve the Paris Agreement’s goal of limiting global temperature rise to well below two degrees Celsius above pre-Industrial Revolution levels, which is expected to significantly reduce the risks and impacts of climate change.

Teijin established a method for calculating CO2 emissions during the manufacture of Tenax carbon fibres, which has made it possible to conduct Life Cycle Assessment (LCA) of all carbon fibres offered by Teijin. By doing so, Teijin became the first company in the industry to be able to achieve this. Not only calculates its own manufacturing processes, but Teijin also evaluates the carbon footprint of its customers’ manufacturing process with this method.

Teijin Aramid, a core aramid business of the Teijin Group headquartered in the Netherlands, has improved the carbon footprint of its para-aramid product called Twaron by 28% compared to 2014 according to the applicable ISO standards 14040 and 14044. The benefit of using Twaron can be calculated economically and environmentally by the Customer Benefit Model (CBM) developed by Teijin Aramid.

Teijin is also at the cutting edge of what is possible to exceed demands in our ever-changing world. Providing solutions to help reduce vehicle weight, which in turn helps reduce gas emissions and improves overall fuel performance, means we are impacting countless journeys around the world. Teijin Automotive Technologies’ has one of these solutions called TCA Ultra Lite, a 1.2 specific gravity ultra lightweight sheet moulding compound formulation that uses glass fibre reinforced plastic (GFRP). Carbon fibre reinforced thermoplastic (CFRTP) Sereebo is another example. Conventional carbon fibre-reinforced plastic (CFRP) that utilises thermosetting resins requires several minutes to several hours to mould, making it unfit for components used in mass-produced automobiles. However, by making use of thermoplastic resins, we have been able to significantly reduce these moulding times. This has allowed Teijin to establish the world’s first mass-production technology that is able to mould CFRP in only one minute.

In addition to this, the Teijin Group’s fibres and products converting company Teijin Frontier offers apparel manufacturers numerous products that help reduce CO2 emissions, including ECOPET, a recycled polyester fibre that utilises used PET bottles and fibre scraps as raw materials, and SOLOTEX, which uses plant-derived ingredients for a portion of its polymers.

Teijin Frontier has also developed a system to calculate CO2 emissions within the polyester fibre manufacturing process, thereby enabling the implementation of LCA. It will gradually expand the scope of its operations to cover more textiles, including those used for weaving and dyeing, while working with its partner companies to evaluate the entire life cycle of polyester fibre products.
