Alternative fuels are one of the possibility to reduce clinker production costs. Dirk Lechtenberg sheds lights on how to use alternate fules efficently.
The cement Industry is suffering from addition of new capacities which will result in under-utilisation of new as well as existing capacities. The cement Industry today is characterized through:
a) addition of new capacities which will weaken the pricing power of manufacturers
b) Government’s negative attitude towards the industry (CO² Issue)
c) Increase in operating costs resulting in lower margins
d) Slowdown in real estate and construction activities resulting in lower demand growth
e) Higher financing costs resulting from financial crises. Due to lower demand of clinker, the current situation requires the following conclusion:
Not the Capacity is important: The lowest Production cost per tonne of clinker is now important! But how to reduce the production costs?
The first classical cost- cutting exercises are already implemented or in due course in the cement industry, such as laid off employees, cutting of wages, investment stops and others.
Due to the excellent market situation of the cement Industry in the past years, most companies have focused on an increase in production and market shares with takeover of competitors and building up more capacities. Most of the market participants were growing without any optimization of the organization or production. The multinational groups like Holcim, Heidelberg Cement and Lafarge have a long term experience with the use of Alternative Fuels and Raw materials (AFR) and have built up their internal organisation focusing on AFR. The following table shows the cost reduction volume with a substitution of 25 per cent rice husks at market conditions in September 2012.
Above shown Calculation is for a "standard" 1 mio tons Clinker production Plant with Precalciner, calculated without thermal losses and with a Rice Husk purchase price of 30 UD$ at the flame. Values for CO² emission reduction are not calculated
Even with lower fossil fuel prices, the use of Alternative Fuels can have a significant cost reduction. In India, many municipalities or regions usually don’t have established collection and disposal infrastructure for wastes, such as agricultural wastes or municipal solid wastes. Therefore a collection and eventually processing have to be developed by the cement plants or contractors. Collection and use of biomass wastes, such as rice husks or coconut shells is easier to implement, as no processing is needed and the available trucks for Cement transports can be used.
Table 3: Calorific Value of Biomass Wastes
The use of alternative Fuels is well known in the Cement industry, but even due to the current market situation, this is not the score business of a cement plant and often failed by the following constrains:
• Not the score business and
• No experience of Employees
• Permitting problems
• No human resources for development
• Cut and dried opinions
• Advanced arguments (in Europe they get clean wastes, but not here!)
• Communication failure with communities
• Wrong economical figures and assumptions ( cement plants are thinking that high investment costs are needed for storage, dosing and feeding systems according to "German Standards")
MVW Lechtenberg has developed a 3-stage plan, which allows the cement plants to be on the safe side while starting up the use of RDF. For turnkey project implementation, the company works on the following three phases:
Phase I
Verification and classification of existing wastes types available at source,
• Suitability of available wastes as AF, and recommended feeding points.
• Quality requirements of alternative fuels,
• Impact of AF utilization on clinker chemistry and production process,
• Impact on air quality (emissions),
• Thermal energy substitution, and economical benefits,
• Possible Greenhouse Gas emission savings (CO² Calculation) and legal requirements. • Project capital investment cost evaluation and return on investment.
In this stage, the communication with the society and with the Authorities is most important. Especially in India are many constraints of the Authorities against the use of Alternative Fuels, as this is considered as "waste incineration". Often, e.g. in the emirates, are many local arguments against the foreign multinational cement groups in the use of alternative fuels. ("There are coming here, using cheap labor, paying no taxes and polluting the environment") Therefore, the communication, explanation and lobbying pro Alternative Fuels are one important activity of MVW Lechtenberg. In this article we focus only on the development of Phase I, but will give a short overview about the following working stages:
Phase II
• MVW will support the cement plant in equipment choice, requisition and equipment verification.
• Support in negotiation contracts with waste suppliers
• Permitting issues
• Development of "Turnkey-Project" incl. engineering and sketch drawings for imported and local manufactured items.
Phase III
• support in the successful implementation of the Alternative Fuels project incl. ongoing monitoring / quality management
The use of alternative Fuels and the development of such a project is always standardised, despite local or technical differences. Each Kiln responds different on the substitution of Alternative Fuels, and in the vicinity of cement plants are always different types of wastes available. Most of the cement plants use Alternative Fuels "by chance".
The basic principles for the use of Alternative Fuels are as follows:
• The chemical quality of the fuel must meet regulatory standards, assuring environmental protection.
• The calorific value of the fuel must be stable enough to allow control of the supply of energy to the kiln, as the achievement of homogeneous clinker requires a well controlled combustion process.
• The physical form of the fuel must allow easy handling of the material for transportation and a controlled flow into the kiln.
• The fuels must not introduce the chemical species into the clinker production process that might be deleterious to the stability of the process or the performance of the product.
The Quality of agriculture wastes such as rice husks, coconut shells or Bagasse is, depending on the origin, with a high variation of moisture content, silicate or other constituents. Therefore detailed analyses are needed.
Based on these analyses, detailed study about the effects on Cofiring these fuels have to be done. MVW Lechtenberg has developed a tool to calculate these effects on a theoretical base, which will give the cement plant a detailed summary on such effects and guidelines and recommendations for the substitution.
Carbon Credits
The Kyoto Protocol to the United Nations Framework Convention on Climate Change strengthens the international response to climate change. The developed countries commit themselves to reducing their collective emissions of six key greenhouse gases by at least 5 per cent.
Under the Kyoto Protocol, the EU committed itself to reducing its greenhouse gases emissions by 8% during the first commitment period from 2008 to 2012. This target is shared between the Member States under a legally binding burden-sharing agreement, which sets individual emissions targets for each Member State. Under the EU emissions trading scheme, which is mandatory, the EU Member States will cap direct CO2 emissions from energy-intensive companies (steel, power plants, oil refineries, paper mills, glass and cement installations) by issuing allowances as to how much CO2 these companies are allowed to emit. Reductions below the limits will be tradable.
Companies that achieve reductions can sell them to companies that have problems staying within their limits or for which emission reduction measures are too expensive in comparison with what the allowances will cost. Any company may also increase its emissions above the level of allowances it is issued by acquiring additional allowances from the market The Commission adopted on 23rdJuly 2003 a proposal that links credits from JI and CDM projects with the emissions trading system. Indeed, under the Kyoto Protocol, Joint Implementation (JI) and the Clean Development Mechanism (CDM) will allow industrialised countries to achieve part of their emission reduction commitments by conducting emission-reducing projects abroad and counting the reductions achieved toward their own commitments. Under this proposal, companies and Governments will be allowed to convert credits from JI and CDM projects for use towards meeting their commitments. JI and CDM allow respectively for the creation, acquisition and transfer of "emission reduction units" (ERUs) and "certified emissions reductions" (CERs). Projects of Cement Plants which are intending to use Alternative Fuels such as Biomass or Refuse Derived Fuels with a certain biogenic (renewable) content, can get "Certified emission reductions" CER`s in order to finance their Alternative Fuel Projects, as the fossil CO² emissions are reduced.
There are two sources for "Green House gas" emission savings:
• Reduction of Landfill gas (Methane) if RDF from Municipal Solid wastes is used and fossil fuel emission in the Kiln.
MVW Lechtenberg is calculating the possible CO² emission savings and developing the needed procedures to receive such CER`s.
Storage / Dosing / Feeding systems
There is a huge variety of needed technical Equipments for Storage, Dosing and feeding of Alternative Fuels available on the Market. As there is no "standard" utilisation, it is advised to start with simple technical equipment in order to be able to gather some experience before investing in a "state of the art" technology. Especially in these days, lowering the investment costs is one mayor key in a successful alternative fuel implementation. As an example, the investment costs for a "state of the art" storage, dosing and feeding system for 10 tons Rice Husks is available on the market for 5 mio €, but can also be implemented for less then 500.000 €.
Such a system is consisting of a receiving area, feeding a hopper with a wheelloader, volumetric or gravimetric dosing, and pneumatic transport system. In India, MVW Lechtenberg is collaborating with TECPRO SYSTEMS- which is a leading EPC contractor for such systems. In Ajmer, Rajasthan, the first RDF Production facility was built by Tecpro Systems and MVW Lechtenberg; processing 300 tons of mixed Municipal Solid wastes into defined refuse derived fuels.
Most important for such Investments is the flexibility of the system. This flexibility is needed to be independent in the purchase of various alternative fuels. One example: if the rice farmers asking to high prices for the rice Husks, the cement Plant can switch to olive kernel or other available Fuels. This is also important in order to use Refuse derived Fuels (RDF) , consisting of paper / plastics fractions with the same installation.
The use of RDF made from industrial wastes or Municipal Solid Wastes (MSW) is common practice in European and some Asian cement plants, as an existing waste collection and disposal infrastructure exists.
Economics on clinker production process
The total production costs for RDF are, depending on the local energy and labor costs are calculated with 25- 30€ / tonne. Therefore in India the use of alternative fuels made from industrial wastes or Municipal Solid waste is highly economic with the current high fossil fuel costs. MVW Lechtenberg has developed a calculation tool to implement different waste types, separation values, transport distances, gate fees (or input costs) and production costs on local base. Wear and spare part costs, based on working experience with different waste materials and different equipment suppliers are integrated in the modular system. Typical Production costs (maintenance, energy, wear parts/ spare parts) for RDF from mixed industrial wastes are starting at 15 € / ton plus Labor and Depreciation costs. It is foreseen, that the fossil fuel prices will increase further- with a higher need to implement alternative fuels and cost reduction by e.g. waste heat recovery.
MVW Lechtenberg has developed a "low cost startup package" for cement Plants which are intending to use Alternative Fuels made from Municipal Solid wastes and other available biomass wastes. This start up package consists of Equipment’s from well-known Indian and European equipment suppliers for the production, dosing and feeding of such fuels to the Kiln and includes the needed Feasybility studies, Environmental Impact assessment and training for the start up period. This start up package with a feeding capacity of 10 tonne RDF/Alternative Fuel is available for a lump sum of 3,5 Mio €. Interested parties can visit such Installation, developed by MVW Lechtenberg and TECPRO SYSTEMS in Ajmer, India.
The use of RDF has a direct impact on the clinker production process and production capacity. The presence of chlorine is the most critical factor in the thermal process. Chlorine may react with calcium. In that case it will end as CaCl2 in the clinker. But most of it will react with sodium or potassium to NaCl or KCl. These salts sublimate in the calcinations zone and recristallise in the decarbonisation zone, which results in an internal chloride cycle. As the chloride concentration increases this may lead to blockages in the cyclone pipes, resulting in a kiln shutdown. To fore come this, the chlorine content of the substitute fuel must be monitored carefully. If there is higher chlorine content in the substitute fuel, input of that fuel must be reduced or a special bypass must be constructed to clean the gases from NaCl and KCl.
At the same time presence of Alkalis as also Sulphur has to be monitored carefully. Any unbalance in the system will provide to ring formations in the kiln and build ups at kiln inlet and lower stages cyclone preheater.
Introduced Humidity of the fuels will reduce the available gas volume. More Oxygen will be needed for the complete incineration of bigger sized RDF will be needed. (Increasing the Fan Capacities with higher energy consumption). As a Result, the efficiency losses (thermal efficiency) will be at least 10 per cent of the introduced RDF. (From 1000 kcal introduced RDF, only 900 kcal will be used for heating purposes, 10 per cent are lost due to the composition and extra needed energy input).If a clinker production loss will occur is depending on the following circumstances:
• Humidity / quality of RDF
• Quantities of introduced RDF
• Kiln performance
From our experience we knew, that a substitution of up to 20 per cent substitution rate (in calorific value) can be done without any clinker production losses. With certain modifications, higher substitution rates can be achieved. If we look at the German cement Industry with an average alternative Fuel substitution of almost 61% in 2012 with solid alternative fuels, the production rates are only 90- 95% of the designed kiln capacity. With such high substitution rates of alternative fuels, the clinker production costs can be reduced by up to 10 € per ton of clinker! With possible "gate fees" for hazardous wastes, these figures can be optimised. Especially in India is normally no existing disposal of hazardous wastes such as solvents, oils, refinery sludge, pesticides and others available. The cement plants can take a significant role in the environmental friendly disposal and use of such wastes especially in developing countries.

Advertising or branding is never about driving sales. It’s about creating brand awareness and recall. It’s about conveying the core values of your brand to your consumers. In this context, why is branding important for cement companies? As far as the customers are concerned cement is simply cement. It is precisely for this reason that branding, marketing and advertising of cement becomes crucial. Since the customer is unable to differentiate between the shades of grey, the onus of creating this awareness is carried by the brands. That explains the heavy marketing budgets, celebrity-centric commercials, emotion-invoking taglines and campaigns enunciating the many benefits of their offerings.
Marketing strategies of cement companies have undergone gradual transformation owing to the change in consumer behaviour. While TV commercials are high on humour and emotions to establish a fast connect with the customer, social media campaigns are focussed more on capturing the consumer’s attention in an over-crowded virtual world. Branding for cement companies has become a holistic growth strategy with quantifiable results. This has made brands opt for a mix package of traditional and new-age tools, such as social media. However, the hero of every marketing communication is the message, which encapsulates the unique selling points of the product. That after all is crux of the matter here.
While cement companies are effectively using marketing tools to reach out to the consumers, they need to strengthen the four Cs of the branding process – Consumer, Cost, Communication and Convenience. Putting up the right message, at the right time and at the right place for the right kind of customer demographic is of utmost importance in the long run. It is precisely for this reason that regional players are likely to have an upper hand as they rely on local language and cultural references to drive home the point. But modern marketing and branding domain is exponentially growing and it would be an interesting exercise to tabulate and analyse its impact on branding for cement.

Dr Hitesh Sukhwal, Deputy General Manager – Environment, Udaipur Cement Works Limited (UCWL) takes us through the multifaceted efforts that the company has undertaken to keep emissions in check with the use of alternative sources of energy and carbon capture technology.
Tell us about the policies of your organisation for the betterment of the environment.
Caring for people is one of the core values of our JK Lakshmi Cement Limited. We strongly believe that we all together can make a difference. In all our units, we have taken measures to reduce carbon footprint, emissions and minimise the use of natural resources. Climate change and sustainable development are major global concerns. As a responsible corporate, we are committed with and doing consistent effort small or big to preserve and enrich the environment in and around our area of operations.
As far as environmental policies are concerned, we are committed to comply with all applicable laws, standards and regulations of regulatory bodies pertaining to the environment. We are consistently making efforts to integrate the environmental concerns into the mainstream of the operations. We are giving thrust upon natural resource conservation like limestone, gypsum, water and energy. We are utilising different kinds of alternative fuels and raw materials. Awareness among the employees and local people on environmental concerns is an integral part of our company. We are adopting best environmental practices aligned with sustainable development goals.
Udaipur Cement Works Limited is a subsidiary of the JK Lakshmi Cement Limited. Since its inception, the company is committed towards boosting sustainability through adopting the latest art of technology designs, resource efficient equipment and various in-house innovations. We are giving thrust upon renewable and clean energy sources for our cement manufacturing. Solar Power and Waste Heat Recovery based power are our key ingredients for total power mix.
What impact does cement production have on the environment? Elaborate the major areas affected.
The major environmental concern areas during cement production are air emissions through point and nonpoint sources due to plant operation and emissions from mining operation, from material transport, carbon emissions through process, transit, noise pollution, vibration during mining, natural resource depletion, loss of biodiversity and change in landscape.
India is the second largest cement producer in the world. The Indian cement industry is well known for its energy and natural resource efficiency worldwide. The Indian cement industry is a frontrunner for implementing significant technology measures to ensure a greener future.
The cement industry is an energy intensive and significant contributor to climate change. Cement production contributes greenhouse gases directly and indirectly into the atmosphere through calcination and use of fossil fuels in an energy form. The industry believes in a circular economy by utilising alternative fuels for making cement. Cement companies are focusing on major areas of energy efficiency by adoption of technology measures, clinker substitution by alternative raw material for cement making, alternative fuels and green and clean energy resources. These all efforts are being done towards environment protection and sustainable future.
Nowadays, almost all cement units have a dry manufacturing process for cement production, only a few exceptions where wet manufacturing processes are in operation. In the dry manufacturing process, water is used only for the purpose of machinery cooling, which is recirculated in a closed loop, thus, no polluted water is generated during the dry manufacturing process.
We should also accept the fact that modern life is impossible without cement. However, through state-of-the-art technology and innovations, it is possible to mitigate all kinds of pollution without harm to the environment and human beings.
Tell us about the impact blended cement creates on the environment and emission rate.
Our country started cement production in 1914. However, it was introduced in the year 1904 at a small scale, earlier. Initially, the manufacturing of cement was only for Ordinary Portland Cement (OPC). In the 1980s, the production of blended cement was introduced by replacing fly ash and blast furnace slag. The production of blended cement increased in the growth period and crossed the 50 per cent in the year 2004.
The manufacturing of blended cement results in substantial savings in the thermal and electrical energy consumption as well as saving of natural resources. The overall consumption of raw materials, fossil fuel such as coal, efficient burning and state-of-the-art technology in cement plants have resulted in the gradual reduction of emission of carbon dioxide (CO2). Later, the production of blended cement was increased in manifolds.
If we think about the growth of blended cement in the past few decades, we can understand how much quantity of , (fly ash and slag) consumed and saved natural resources like limestone and fossil fuel, which were anyhow disposed of and harmed the environment. This is the reason it is called green cement. Reduction in the clinker to cement ratio has the second highest emission reduction potential i.e., 37 per cent. The low carbon roadmap for cement industries can be achieved from blended cement. Portland Pozzolana Cement (PPC), Portland Slag Cement (PSC) and Composite Cement are already approved by the National Agency BIS.
As far as kilogram CO2 per ton of cement emission concerns, Portland Slag Cement (PSC) has a larger potential, other than PPC, Composite Cement etc. for carbon emission reduction. BIS approved 60 per cent slag and 35 per cent clinker in composition of PSC. Thus, clinker per centage is quite less in PSC composition compared to other blended cement. The manufacturing of blended cement directly reduces thermal and process emissions, which contribute high in overall emissions from the cement industry, and this cannot be addressed through adoption of energy efficiency measures.
In the coming times, the cement industry must relook for other blended cement options to achieve a low carbon emissions road map. In near future, availability of fly ash and slag in terms of quality and quantity will be reduced due to various government schemes for low carbon initiatives viz. enhance renewable energy sources, waste to energy plants etc.
Further, it is required to increase awareness among consumers, like individual home builders or large infrastructure projects, to adopt greener alternatives viz. PPC and PSC for more sustainable
resource utilisation.
What are the decarbonising efforts taken by your organisation?
India is the world’s second largest cement producer. Rapid growth of big infrastructure, low-cost housing (Pradhan Mantri Awas Yojna), smart cities project and urbanisation will create cement demand in future. Being an energy intensive industry, we are also focusing upon alternative and renewable energy sources for long-term sustainable business growth for cement production.
Presently, our focus is to improve efficiency of zero carbon electricity generation technology such as waste heat recovery power through process optimisation and by adopting technological innovations in WHR power systems. We are also increasing our capacity for WHR based power and solar power in the near future. Right now, we are sourcing about 50 per cent of our power requirement from clean and renewable energy sources i.e., zero carbon electricity generation technology. Usage of alternative fuel during co-processing in the cement manufacturing process is a viable and sustainable option. In our unit, we are utilising alternative raw material and fuel for reducing carbon emissions. We are also looking forward to green logistics for our product transport in nearby areas.
By reducing clinker – cement ratio, increasing production of PPC and PSC cement, utilisation of alternative raw materials like synthetic gypsum/chemical gypsum, Jarosite generated from other process industries, we can reduce carbon emissions from cement manufacturing process. Further, we are looking forward to generating onsite fossil free electricity generation facilities by increasing the capacity of WHR based power and ground mounted solar energy plants.
We can say energy is the prime requirement of the cement industry and renewable energy is one of the major sources, which provides an opportunity to make a clean, safe and infinite source of power which is affordable for the cement industry.
What are the current programmes run by your organisation for re-building the environment and reducing pollution?
We are working in different ways for environmental aspects. As I said, we strongly believe that we all together can make a difference. We focus on every environmental aspect directly / indirectly related to our operation and surroundings.
If we talk about air pollution in operation, every section of the operational unit is well equipped with state-of-the-art technology-based air pollution control equipment (BagHouse and ESP) to mitigate the dust pollution beyond the compliance standard. We use high class standard PTFE glass fibre filter bags in our bag houses. UCWL has installed the DeNOx system (SNCR) for abatement of NOx pollution within norms. The company has installed a 6 MW capacity Waste Heat Recovery based power plant that utilises waste heat of kiln i.e., green and clean energy source. Also, installed a 14.6 MW capacity solar power system in the form of a renewable energy source.
All material transfer points are equipped with a dust extraction system. Material is stored under a covered shed to avoid secondary fugitive dust emission sources. Finished product is stored in silos. Water spraying system are mounted with material handling point. Road vacuum sweeping machine deployed for housekeeping of paved area.
In mining, have deployed wet drill machine for drilling bore holes. Controlled blasting is carried out with optimum charge using Air Decking Technique with wooden spacers and non-electric detonator (NONEL) for control of noise, fly rock, vibration, and dust emission. No secondary blasting is being done. The boulders are broken by hydraulic rock breaker. Moreover, instead of road transport, we installed Overland Belt Conveying system for crushed limestone transport from mine lease area to cement plant. Thus omit an insignificant amount of greenhouse gas emissions due to material transport, which is otherwise emitted from combustion of fossil fuel in the transport system. All point emission sources (stacks) are well equipped with online continuous emission monitoring system (OCEMS) for measuring parameters like PM, SO2 and NOx for 24×7. OCEMS data are interfaced with SPCB and CPCB servers.
The company has done considerable work upon water conservation and certified at 2.76 times water positive. We installed a digital water flow metre for each abstraction point and digital ground water level recorder for measuring ground water level 24×7. All digital metres and level recorders are monitored by an in-house designed IoT based dashboard. Through this live dashboard, we can assess the impact of rainwater harvesting (RWH) and ground water monitoring.
All points of domestic sewage are well connected with Sewage Treatment Plant (STP) and treated water is being utilised in industrial cooling purposes, green belt development and in dust suppression. Effluent Treatment Plant (ETP) installed for mine’s workshop. Treated water is reused in washing activity. The unit maintains Zero Liquid Discharge (ZLD).
Our unit has done extensive plantations of native and pollution tolerant species in industrial premises and mine lease areas. Moreover, we are not confined to our industrial boundary for plantation. We organised seedling distribution camps in our surrounding areas. We involve our stakeholders, too, for our plantation drive. UCWL has also extended its services under Corporate Social Responsibility for betterment of the environment in its surrounding. We conduct awareness programs for employees and stakeholders. We have banned Single Use Plastic (SUP) in our premises. In our industrial township, we have implemented a solid waste management system for our all households, guest house and bachelor hostel. A complete process of segregated waste (dry and wet) door to door collection systems is well established.
Tell us about the efforts taken by your organisation to better the environment in and around the manufacturing unit.
UCWL has invested capital in various environmental management and protection projects like installed DeNOx (SNCR) system, strengthening green belt development in and out of industrial premises, installed high class pollution control equipment, ground-mounted solar power plant etc.
The company has taken up various energy conservation projects like, installed VFD to reduce power consumption, improve efficiency of WHR power generation by installing additional economiser tubes and AI-based process optimisation systems. Further, we are going to increase WHR power generation capacity under our upcoming expansion project. UCWL promotes rainwater harvesting for augmentation of the ground water resource. Various scientifically based WHR structures are installed in plant premises and mine lease areas. About 80 per cent of present water requirement is being fulfilled by harvested rainwater sourced from Mine’s Pit. We are also looking forward towards green transport (CNG/LNG based), which will drastically reduce carbon footprint.
We are proud to say that JK Lakshmi Cement Limited has a strong leadership and vision for developing an eco-conscious and sustainable role model of our cement business. The company was a pioneer among cement industries of India, which had installed the DeNOx (SNCR) system in its cement plant.
