Opportunities for MSW in India

With urbanisation and industrialisation increasing around the world (despite a temporary COVID-19 setback), the issue of waste management and particularly of municipal solid waste will be a critical challenge to sustainable development.
Global waste production is expected to reach 27 billion tonnes per year by 2050, a third of which will be generated in Asia.1 India will be a major contributor: it currently generates more than 150,000 tonne per day of solid waste, approximate 54.75 million tonne (MT) per year.2
The government steps in To tackle this growing pile of waste ??much of which has traditionally ended up in landfills ??the Indian government has issued two directives:
Guidelines on Usage of Refuse Derived Fuel in Various Industries
Central Public Health and Environmental Engineering Organisation; Ministry of Housing and Urban Affairs (September 2018).
Guideline Document Uniform Framework for Extended Producers Responsibility
Under Plastic Waste Management Rules, 2016; Ministry of Environment, Forest and Climate Change (June 2020)
The first of these ??which is now in force ??aims to prevent the landfill of waste that are ??ombustible in nature but are not recyclable such as soiled paper, soiled cloth, contaminated plastics, multi-layer packaging materials, other packaging materials, pieces of leather, rubber, tyre, polystyrene, wood, etc.??
The second of ??which is still in consultation stage ??deals with plastic waste. Among other things, it will make companies that use plastic packaging for their products responsible for collecting and disposing of that packaging.4 One solution to both of these challenges is the substitution of fossil fuels by alternative refusederived fuels (RDF) at cement plants and thermal power plants.
The use of waste as an alternative fuel in the cement industry has a longstanding history, particularly in Europe, where substitution rates can reach well over 50 per cent and companies are pushing to reach 100 per cent. This is supported by generous gate fees paid by waste producers to cement companies and tight carbon emissions regulations (some alternative fuels are considered carbon neutral under EU regulations). Indeed, the use of RDF and other alternative fuels is acknowledged as a key step in the cement industry?? path to carbon neutrality, alongside energy efficiency and the use of supplementary cementitious materials.5
To encourage the use of RDF, the expenses so incurred for transportation of RDF, beyond 100 km distance may be booked by industries under their Corporate Social Responsibility (CSR) commitment as per Section 135 of the Companies Act, 2013.3 RDF in India
The Cement Manufacturers Association (CMA) had expressed its commitment towards disposal of wastes and plastics and use of alternate fuels and raw materials.6 The past President (2018 to 2020) of CMA, Mr. Mahendra Singhi, commented; ??he Indian cement industry has been able to use almost 75 million tonnes of waste as a replacement of raw materials and fuels??
Mr. Singhi, who is also the MD and CEO of Dalmia Cement (Bharat) Ltd, added that the Indian cement sector has played an important role in the transition to a low carbon economy and is fully committed towards efficiency in terms of clean and green operations.
As part of the new guidelines, cement companies are now required to utilise RDF in any kiln located within 400 km of an RDF production facility.
Unusually, it is also the cement companies that are required to bear the cost of this rule, for example; there are no gate fees payable for taking waste and cement companies have to pay the transportation fees for the first 100 km radius of the plant.
Managing the increasing quantity of MSW generating in India is a big challenge. A high percentage of MSW including non-recyclable combustible fraction ends up in landfills. In spite of enough demand a supply of RDF by vibrant private sector in waste management and cement industry and existence of enabling policy framework of SWM Rules 2016, current on ground situation is not very promising due to several challenges as depicted below:

The regulation envisages a rising scale of substitution rate from 6 per cent in the first year up to 15 per cent in the third year, although an evaluation of the amount of available RDF vs the energy needs of the cement industry suggest that a thermal substitution rate of 7.1 per cent may be the maximum achievable (Table 1).
The data captures the details of daily exposed garbage. There is a significant quantum of legacy wastes which needs to be processed to make it usable RDF.
A Partner for Sustainable Waste Management
The new regulations position the cement industry as a key partner in solving India?? waste challenges.
However, there are certain challenges in its processing. Notably, the quality of RDF currently produced in India is much lower than that of in other regions, with lower calorific value and much higher moisture content. In worst scenario the ??ombustible wastes??which ??hould at least be heat neutral??and ??hould not affect the Clinker quality??
The requirement for Indian cement companies to finance the capex required to begin using RDF has also focused the market on economically viable, simple and standard alternative fuels feeding systems to meet the possible substitution rate up to 7 per cent. Going forward, to increase substitution rates, the cement industry needs accuracy in feeding and dosing system, efficient process and alternative fuel material analysis. To support these requirements, cement industry demands proven technologies like; rotor weigh-feeders, a HOTDISC? Combustion Device with solid alternative fuel ash exaction possibilities and utilisation of solid alternative fuel ash, chlorine gas by-pass system and utilisation of chlorine rich dust.

Cement manufacturers like, Dalmia Cement, which targets higher levels of alternative fuel substitution rates, reportedly up to 100 per cent, as part of a corporate ambition to manufacture the greenest cement in the world.7 FLSmidth is supporting this ambition as the supplier of Dalmia Cement?? new plant at Rajgangpur, where the equipment and design of the plant were carefully selected to maximise the potential for alternative fuels and raw materials use, as well as to reduce energy efficiency and heat loss.Tackling plastics Plastic waste has garnered recent attention due to littering of crucial ecosystems, most notably that of oceans. According to one estimate, between 4.8 MT and 12.7 MT of plastic waste enters the oceans each year.8 Reversing this damaging pattern has been recognised as integral to sustainable development and is a key target of the fourteenth UN Sustainable Development Goal.9 As part of the solution to this challenge, the Indian government has introduced rules that make use and disposal of plastic packaging as the responsibility of the generator. This impacts the Indian cement industry in a couple of different ways.
Firstly, as a user of plastic packaging for its products ??and with bagged cement playing a larger role in the Indian cement market than in other regions ??the industry is faced with the need to set up systems to collect that plastic or switch to alternative paperbased packaging.However, the industry may also find itself (again) as a crucial part of the solution, due to its ability to utilise plastic waste as an alternative fuel. One opportunity arising from the regulations may be for the cement industry to partner with others that use plastic packaging to create efficient collection and processing systems for plastic waste that sees the non-recyclable elements made available for use in cement kilns.
Conclusion
Waste is a serious challenge to sustainable development. Finding ways to use the non-recyclable elements in a productive way is therefore key to
setting humanity on a path to a cleaner, greener future. With its huge capacity to utilise RDF, the cement industry has a vital role in doing this. And the benefits of doing so reach far beyond (emptier) landfills. RDF substitution of fossil fuels reduces both the cement industry?? carbon emissions, as well as the necessity to mine fossil fuels. Supporting the use of alternative fuels is therefore a priority for FLSmidth through our MissionZero ambitions to enable zero-emissions cement production.
As part of this, we have committed to providing cement producers the solutions needed to operate with 100 per cent alternative fuels. This goes beyond the provision of equipment to include our significant process experience ??from initial reception and handling of alternative fuels through their impact on conditions in the kiln and on the final chemistry of cement. This deep understanding of the process enables us to assist any plant in solving the challenges that alternative fuels bring ??whether just starting out or reaching for 100 per cent.

Adani Cement has entered a strategic partnership with the National Real Estate Development Council (Naredco) to support India’s construction needs with a focus on sustainability, workforce capability and modern building technologies. The collaboration brings together Adani Cement’s building materials portfolio, research and development strengths and technical expertise with Naredco’s nationwide network of more than 15,000 member organisations. The agreement aims to address evolving demand across housing, commercial and infrastructure sectors.
Under the partnership, the organisations will roll out skill development and certification programmes for masons, contractors and site supervisors, with training to emphasise contemporary construction techniques, safety practices and quality standards. The programmes are intended to improve project execution and on-site efficiency and to raise labour productivity through standardised competencies. Emphasis will be placed on practical training and certification pathways that can be scaled across regions.
The alliance will function as a platform for knowledge sharing and technology exchange, facilitating access to advanced concrete solutions, innovative construction practices and modern materials. The effort is intended to enhance structural durability, execution quality and environmental responsibility across developments while promoting adoption of low-carbon technologies and green cement alternatives. Companies expect these measures to contribute to longer term resilience of built assets.
Senior executives conveyed that the partnership reflects a shared commitment to strengthening quality and sustainability in construction and that closer engagement with developers will help integrate advanced materials and technical support throughout the project lifecycle. Leadership noted the need for responsible construction practices as urbanisation accelerates and indicated that the association should encourage wider adoption of green building norms and collaboration within the real estate and construction ecosystem.
The organisations said they will also explore integrated building solutions, including ready-mix concrete offerings, while supporting initiatives aligned with affordable and inclusive housing. The partnership will progress through engagements, conferences and joint training programmes targeting rapidly urbanising cities and growth centres where demand for efficient and environmentally responsible construction grows. Naredco, established under the aegis of the Ministry of Housing and Urban Affairs, will leverage its policy and advocacy role to support implementation.
Operational excellence in cement is no longer about producing more—it is about producing smarter, cleaner and more reliably, where cost per tonne meets carbon per tonne.
Operational excellence in cement has moved far beyond the old pursuit of ‘more tonne’. The new benchmark is smarter, cleaner, more reliable production—delivered with discipline across process, people and data. In an industry where energy can account for nearly 30 per cent of manufacturing cost, even marginal gains translate into meaningful value. As Dr SB Hegde, Professor, Jain College of Engineering & Technology, Hubli and Visiting Professor, Pennsylvania State University, USA, puts it, “Operational excellence… is no longer about producing more. It is about producing smarter, cleaner, more reliably, and more sustainably.” The shift is structural: carbon per tonne will increasingly matter as much as cost per tonne, and competitiveness will be defined by the ability to stabilise operations while steadily lowering emissions.
From control rooms to command centres
The modern cement plant is no longer a handful of loops watched by a few operators. Control rooms have evolved from a few hundred signals to thousands—today, up to 25,000 signals can compete for attention. Dr Rizwan Sabjan, Head – Global Sales and Proposals, Process Control and Optimization, Fuller Technologies, frames the core problem plainly: plants have added WHRS circuits, alternative fuels, higher line capacities and tighter quality expectations, but human attention remains finite. “It is very impossible for an operator to operate the plant with so many things being added,” he says. “We need somebody who can operate 24×7… without any tiredness, without any distraction… The software can do that for us better.”
This is where advanced process control shifts from ‘automation spend’ to a financial lever. Dr Hegde underlines the logic: “Automation is not a technology expense. It is a financial strategy.” In large kilns, a one per cent improvement is not incremental—it is compounding.
Stability is the new productivity
At the heart of operational excellence lies stability. Not because stability is comfortable, but because it is profitable—and increasingly, low-carbon. When setpoints drift and operators chase variability, costs hide in refractory damage, thermal shocks, stop-start losses and quality swings. Dr Sabjan argues that algorithmic control can absorb process disturbances faster than any operator, acting as ‘a co-pilot or an autopilot’, making changes ‘as quick as possible’ rather than waiting for manual intervention. The result is not just fuel saving—it is steadier operation that extends refractory life and reduces avoidable downtime.
The pay-off can be seen through the lens of variability: manual operation often amplifies swings, while closed-loop optimisation tightens control. As Dr Sabjan notes, “It’s not only about savings… there are many indirect benefits, like increasing the refractory life, because we are avoiding the thermal shocks.”
Quality control
If stability is the base, quality is the multiplier. A high-capacity plant can dispatch enormous volumes daily, and quality cannot be a periodic check—it must be continuous. Yet, as Dr Sabjan points out, the biggest error is not in analysis equipment but upstream: “80 per cent of the error is happening at the sampling level.” If sampling is inconsistent, even the best XRF and XRD become expensive spectators.
Automation closes the loop by standardising sample collection, transport, preparation, analysis and corrective action. “We do invest a lot of money on analytical equipment like XRD and XRF, but if it is not put on the closed loop then there’s no use of it,” he says, because results become person-dependent and slow.
Raju Ramachandran, Chief Manufacturing Officer (East), Nuvoco Vistas Corp, reinforces the operational impact from the plant floor: “There’s a stark difference in what a RoboLab does… ensuring that the consistent quality is there… starts right from the sample collection.” For him, automation is not about removing people; it is about making outcomes repeatable.
Human-centric automation
One of the biggest barriers to performance is not hardware—it is fear. Dr Sabjan describes a persistent concern that digital tools exist to replace operators. “That’s not the way,” he says. “The technology is here to help operator… not to replace them… but to complement them.” The plants that realise this early tend to sustain performance because adoption becomes collaborative rather than forced.
Dr Hegde adds an important caveat: tools can mislead without competence. “If you don’t have the knowledge about the data… this will mislead you… it is like… using ChatGPT… it may tell the garbage.” His point is not anti-technology; it is pro-capability. Operational excellence now requires multidisciplinary teams—process, chemistry, physics, automation and reliability—working as one.
GS Daga, Managing Director, SecMec Consultants, takes the argument further, warning that the technology curve can outpace human readiness: “Our technology movement AI will move fast, and our people will be lagging behind.” For him, the industry’s most urgent intervention is systematic skilling—paired with the environment to apply those skills. Without that, even high-end systems remain underutilised.
Digital energy management
Digital optimisation is no longer confined to pilots; its impact is increasingly quantifiable. Raghu Vokuda, Chief Digital Officer, JSW Cement, describes the outcomes in practical terms: reductions in specific power consumption ‘close to 3 per cent to 7 per cent’, improvements in process stability ‘10 per cent to 20 per cent’, and thermal energy reductions ‘2–5 per cent’. He also highlights value beyond the process line—demand optimisation through forecasting models can reduce peak charges, and optimisation of WHRS can deliver ‘1 per cent to 3 per cent’ efficiency gains.
What matters is the operating approach. Rather than patchwork point solutions, he advocates blueprinting a model digital plant across pillars—maintenance, quality, energy, process, people, safety and sustainability—and then scaling. The difference is governance: defined ownership of data, harmonised OT–IT integration, and dashboards designed for each decision layer—from shopfloor to plant head to network leadership.
Predictive maintenance
Reliability has become a boardroom priority because the cost of failure is blunt and immediate. Dr Hegde captures it crisply: “One day of kiln stoppage can cost several crores.” Predictive maintenance and condition monitoring change reliability from reaction to anticipation—provided plants invest in the right sensors and a holistic architecture.
Dr Sabjan stresses the need for ‘extra investment’ where existing instrumentation is insufficient—kiln shell monitoring, refractory monitoring and other critical measurements. The goal is early warning: “How to have those pre-warnings… where the failures are going to come… and then ensure that the plant availability is high, the downtime is low.”
Ramachandran adds that IoT sensors are increasingly enabling early intervention—temperature rise in bearings, vibration patterns, motor and gearbox signals—moving from prediction to prescription. The operational advantage is not only fewer failures, but planned shutdowns: “Once the shutdown is planned in advance… you have lesser… unpredictable downtimes… and overall… you gain on the productivity.”
Alternative fuels and raw materials
As decarbonisation tightens, AFR becomes central—but scaling it is not simply a procurement decision. Vimal Kumar Jain, Technical Director, Heidelberg Cement, frames AFR as a structured programme built on three foundations: strong pre-processing infrastructure, consistent AFR quality, and a stable pyro process. “Only with the fundamentals in place can AFR be scaled safely—without compromising clinker quality or production stability.”
He also flags a ground reality: India’s AFR streams are often seasonal and variable. “In one season to another season, there is major change… high variation in the quality,” he says, making preprocessing capacity and quality discipline mandatory.
Ramachandran argues the sector also needs ecosystem support: a framework for AFR preprocessing ‘hand-in-hand’ between government and private players, so fuels arrive in forms that can be used efficiently and consistently.
Design and execution discipline
Operational excellence is increasingly determined upstream—by the choices made in concept, layout, technology selection, operability and maintainability. Jain puts it unambiguously: “Long term performance is largely decided before the plant is commissioned.” A disciplined design avoids bottlenecks that are expensive to fix later; disciplined execution ensures safe, smooth start-up with fewer issues.
He highlights an often-missed factor: continuity between project and operations teams. “When knowledge transfer is strong and ownership carries beyond commissioning, the plant stabilises much faster… and lifecycle costs reduce significantly.”
What will define the next decade
Across the value chain, the future benchmark is clear: carbon intensity. “Carbon per ton will matter as much as cost per ton,” says Dr Hegde. Vokuda echoes it: the industry will shift from optimising cost per tonne to carbon per ton.
The pathway, however, is practical rather than idealistic—low-clinker and blended cements, higher thermal substitution, renewable power integration, WHRS scaling and tighter energy efficiency. Jain argues for policy realism: if blended cement can meet quality, why it shall not be allowed more widely, particularly in government projects, and why supplementary materials cannot be used more ambitiously where performance is proven.
At the same time, the sector must prepare for CCUS without waiting for it. Jain calls for CCUS readiness—designing plants so capture can be added later without disruptive retrofits—while acknowledging that large-scale rollout may take time as costs remain high.
Ultimately, operational excellence will belong to plants that integrate—not isolate—the levers: process stability, quality automation, structured AFR, predictive reliability, disciplined execution, secure digitalisation and continuous learning. As Dr Sabjan notes, success will not come from one department owning the change: “Everybody has to own it… then only… the results could be wonderful.”
And as Daga reminds the industry, the future will reward those who keep their feet on the ground while adopting the new: “I don’t buy technology for the sake of technology. It has to make a commercial sense.” In the next decade, that commercial sense will be written in two numbers—cost per tonne and carbon per tonne—delivered through stable, skilled and digitally disciplined operations.
