Despite entry of latest technologies like BOPP, woven bags are expected to see rise in their demand due to its cost advantage.

Cement is one of the largest bulk materials being handled on our planet. Producing a material in such massive quantities and distributing is a major logistics challenge. That is where bagging and packaging function comes in handy for the cement industry players.

Though there is hardly any change in the material consumed for manufacturing cement packaging, the new technologies and processes are making them high on productivity, safety, fast, leak-proof, and amenable to automation and ease of load and re-load, when compared to yester years when it was dangerous, hazardous and labour-intensive.

Bags are a common way of distribution in the industry, accounting for about 60 per cent of the product shipped to consumers/users. Bulk packaging, though is yet to catch up on a large scale in India, it is being patronised by some major cement manufacturers and bulk consumers.

Up to 1970s, all cement bags used to be made of jute, which had zero moisture resistance and was prone to high spillage during handling and transportation. Since then switchover to plain woven polypropylene (PP) sacks took place. To upgrade PP bags, concept of lamination was introduced which came with an increase in packaging and handling cost. Some manufacturers are also using BOPP laminated bags to enhance brand value.

Though there are several manufacturers of cement packaging bags in the country, most of the highly advanced automated machinery and systems are being imported from countries like Germany, Italy, Switzerland, the US, Taiwan etc.

Latest technologies
Innovation has been the key for growth of global players like Windmoeller & Hoelscher during the recent years, particularly when it has introduced hot air to seal the moisture-proof sacks that used to be closed with adhesives earlier, thereby reducing production costs and technical process limitations. Another global player, FLSmidth offers complete automation solutions by integrating various product types with that of fully automated packing plants, and automating even loading and unloading activities.

Latest technologies help produce much lighter woven sacks for cement packaging without losing on strength or performance of the cement sack. "Hot air sealed Block Bottom bags’ (BB bags) growth worldwide has also seen development of newer concepts. Very interesting solutions are now available in the market, especially Biaxially-Oriented Polypropylene (BOPP) laminated BB bags have picked up very well in the market," says Anuj Sahni, General Manager – Sales & Marketing, Windmoeller & Hoelscher India. These bags allow very high quality printing on the bags, even bags with metalized and holographic films are being used. BB bags with nonwoven fabric lamination and also with inner paper ply are also providing solutions for packing cement.

Referring to the latest and emerging technologies on the horizon, Pranav Desai, Vice President, R&D and Head Construction Development and Innovation Centre (CDIC), Nuvoco Vistas Corp, says, "The concepts of 2 – 3 ply paper bags are emerging gradually. These bags are biodegradable and protect the inside materials well, but only disadvantage being the cost and handling care – which again pushes up the cost."

In the process of introducing some innovative cement and concrete products into the market, Novoco has played the role of a catalyst for development of different kinds of packaging materials and consequently new packaging equipment. Nuvoco was one of the first building materials company to introduce wet ready-to-use premixed range of concrete and mortar "Instamix" in 35 kg bags. "With these ready-to-use concrete and mortar in bags, Nuvoco has ensured cost-effective and easy construction in any location. It is easy to use on site, as placing and spreading is more efficient," Desai adds.

Nuvoco has also introduced tamper proof bags by double stitching them for its Duraguard brand in the north after its market research showed concerns of duplication of the brand. This was done in order to reinforce its quality and commitment to customers.

Other cost-effective development on paper bags and equipment side are introduction of digital pasting technology. Digital pasting is a solution where the glue consumption on paper bags can be reduced drastically without compromising on bag strength, through precise gluing technology.

Cost-effective
A reasonable amount of cost is incurred towards packaging. However, the customer appreciates the benefits of better packaging and is willing to pay the additional price. ?In terms of stacking up of various options, HDPE bags are the most cost-effective, followed by Laminated PP, BOPP and Paper bags, says Desai of Nuvoco.

Three most used variants in cement packaging in India and also most of the globe, are uncoated sewn cement bags, multiwall paper sacks and hot air sealed block bottom bags (BB bags). "Sewn cement bags are lowest priced than BB bags (extrusion coated), and generally paper sacks are costlier. This is the general trend but eventual costs can depend on more variables," says Sahni.

Woven cement sacks are used multiple times after their primary function for mobilizing sand, aggregates, rubble, bricks and other materials. Also the family of plastics used for producing woven sacks are single family polyolefins, so recyclability is very easy. Besides, plastic has other benefits and is an outstanding material. "We believe that woven bag consumption for cement packaging will keep growing due to above reasons, especially in India," Sahni adds.

But the eventual cost to end users or cement companies depends on various other factors besides only the direct bag costs, i.e., bursting of bags, leakers, pilferage, counterfeiting etc., besides business opportunities in terms of margins, sales turnover, brand value etc. "We have seen cement companies prefer BB bags or multiwall solutions once the end user does a detailed analysis of eventual costs and benefits," Sahni says. The final solution being used also depends on availability of raw materials, logistics available, storage conditions, climatic conditions, and the biggest of them all, i.e., solutions preferred by the end user.

Sustainable packaging is the underlying principle that Nuvoco follows which is replicated through our Laminated PP, moisture and tamper proof cement bags.

"Today, across industry, approximately three per cent of the cement produced is lost in the supply chain and this loss is largely attributed to the cement bags being stored in open environments and use of hooks for unloading across the supply chain, making them vulnerable to damages," says Desai.

Automation
Use of automation in cement packaging is an imperative. "All our packaging machines are calibrated to discharge exact quantity of cement, ensuring higher consistency, speed and accuracy," says Desai.

A packaging solution which has strict dimensional tolerance control and has lesser number of ply would be more suited for automated filling systems. Automated systems are designed to handle a given specification of bags, if bags deviate from these specifications then the automated bag handling systems may show errors or stoppages, says Sahni.

Also cement packing is air assisted, the more the number of layers a packaging solution will have the more difficult it generally gets for the air to escape from the bag, thus reducing filling speeds. Well-designed perforation systems on multiply bags or high-porous paper can help overcome this problem, Sahni adds. Automation is being equally applied to loading and reloading of trucks to avoid congestion in factories.

The housing segment accounts for approximately 65 per cent of the cement consumption, with Affordable housing and Independent House Builders (IHBs) being major consumers. "The IHB’s tend to buy in small lots with constraints in storage space and security of the material. Hence the retail packaging dominates over bulk packaging at an overall level," Desai says.

The demand dynamics could change when we talk about large projects, where the concept of smart silos (capacity up to 8 MT) is picking up and contractors are shifting towards buying bulk cement. Also, with the increase in ready-mix usage, the share of bulk cement is gradually increasing, adds Desai.

Looking ahead
A well-designed packaging can help a cement producer work on all the issues positively and effectively- environmental impact, speed, product protection, shelf life, customer education and brand recall. Thus, the importance of bagging and packaging cannot be over estimated.

Coming to demand side dynamics, the past two years have witnessed a robust demand for cement and the momentum is expected to sustain on account of increased budgetary allocation towards infrastructure (including roads and railways), rural development and affordable housing demand in rural and urban areas especially under PMAY scheme, predicts Desai.

Cement demand has a strong co-relation with the GDP growth with an empirically established ratio of 1.2x to 1.3x, thus providing an outlook of approximately 8 per cent CAGR over next three years.

Factors to be considered for best packaging
The factors one should consider while searching for the best packaging production are:

Sack geometry
Sack converting
Sack design
Appearance
Stack design

Each aspect can be more or less important depending on the region and market the customer is looking for. Furthermore, different applications, availability of the respective materials, or even regional differences, sometimes with historical root causes may influence the decision. The supplier must be able to provide machines for the production of each sack type and after installation service. -Windmoeller & Hoelscher

World Environment Day spotlight on innovation and circularity

On World Environment Day, the Indian cement industry reiterated its commitment to supporting India’s climate ambitions through sustainable manufacturing, resource efficiency and the adoption of cleaner technologies.

The Cement Manufacturers’ Association (CMA) said the sector remains aligned with the Government of India’s Net Zero commitments and is accelerating efforts to reduce its environmental footprint while supporting the country’s infrastructure and development agenda.

Parth Jindal, President, CMA and Managing Director, JSW Cement, said the industry is increasingly adopting cleaner technologies, improving energy efficiency and expanding the use of alternative fuels and raw materials. He also highlighted the growing importance of circular economy practices, where industrial by-products and waste streams from one sector are utilised as resources in another.

“The Indian Cement Industry is aligned to the Government’s commitments on carbon mitigation and is accelerating the adoption of cleaner technologies, resource efficiency and circular economy practices while actively exploring the potential of Carbon Capture, Utilisation and Storage (CCUS) as a critical pathway for deep decarbonisation,” said Jindal.

He added that coprocessing industrial waste and by-products helps conserve natural resources, reduce disposal requirements and lower the environmental footprint across multiple sectors.

According to Jindal, sustainability is no longer limited to manufacturing processes but is increasingly influencing investment decisions, innovation strategies and long-term growth plans within the industry.

Echoing similar views, Dr Raghavpat Singhania, Vice President, CMA and Managing Director, JK Cement, said sustainable development extends beyond emissions reduction and must also focus on responsible resource utilisation and waste minimisation.

“Sustainability in the built environment cannot be measured by emissions alone. It is equally about how efficiently we use resources, how effectively we minimise waste and how responsibly we create the infrastructure that will serve future generations,” said Singhania.

He noted that the cement industry is advancing its sustainability agenda through greater resource efficiency, increased circularity, technological innovation and continuous improvements in manufacturing practices. As a key contributor to India’s infrastructure development, the sector has a critical role to play in balancing economic growth with environmental responsibility.

On the occasion of World Environment Day, industry leaders reaffirmed their commitment to supporting India’s climate goals while delivering the materials required for resilient, durable and sustainable infrastructure.

Environmental sustainability requires immediate action, not just long-term commitments and discussions. Recycling, circular economy practices, and technology-driven waste management can help industries reduce environmental impact while supporting sustainable growth.

Author: Jignesh Kundaria, Director and CEO, Fornnax Technology

World Environment Day serves as an important reminder that environmental sustainability can no longer remain confined to discussions, reports, or long-term commitments. The environmental challenges facing the world today demand immediate, measurable, and collective action. Across industries and communities, waste generation continues to outpace our ability to process it responsibly, placing increasing pressure on ecosystems, natural resources, public health, and the well-being of future generations.

One of the most significant shifts required today is a change in how society perceives waste. Rather than being viewed as a material to be discarded, waste must be recognised as a valuable resource that can contribute to both economic growth and environmental protection when managed through the right technologies and systems. This mindset forms the foundation of the circular economy model that countries across the world are increasingly adopting to reduce landfill dependence, recover valuable materials, and create more sustainable industrial ecosystems.

India has made meaningful progress in strengthening awareness around sustainability, recycling, and environmental responsibility over the past decade. Significant efforts are being made to formalise the recycling sector through improved infrastructure, technology adoption, policy implementation, and broader stakeholder participation. These developments are creating a stronger foundation for responsible waste management and resource recovery across the country.

However, achieving long-term environmental impact requires collaboration from all stakeholders. Industries, policymakers, technology providers, and communities must work together with greater accountability to strengthen recycling ecosystems, encourage responsible waste management practices, and create sustainable outcomes through consistent execution rather than temporary interventions.

As someone closely associated with the recycling industry, I firmly believe that technology will play a decisive role in addressing future environmental challenges. Advanced recycling systems have the potential to recover valuable resources, reduce pollution, minimise landfill burdens, and conserve energy, creating a more sustainable future for generations to come. This belief is deeply reflected in Fornnax’s motto, “Committed to Create a Green Future,” which embodies our commitment to building long-term environmental value through innovation and responsible action.

At the same time, technology alone cannot deliver meaningful change. Real progress requires intent, awareness, participation, and a shared sense of responsibility. Sustainable development can only be achieved when innovation is supported by collective action and a genuine commitment to environmental stewardship.

On this World Environment Day, let us move beyond conversations and take meaningful steps towards creating a cleaner, greener, and more sustainable planet. By embracing innovation, strengthening recycling ecosystems, and acting responsibly today, we can create lasting environmental impact and secure a better future for generations to come.

Dalmia Cement executed a Business Transfer Agreement with Jaiprakash Associates and Adani Infra, to acquire 5.2 MnTPA of cement capacity across Madhya Pradesh and Uttar Pradesh.

Dalmia Cement (Bharat) announced on May 22, 2026 that it had signed a Business Transfer Agreement with Jaiprakash Associates Limited and Adani Infra (India) Limited for the acquisition of cement plants located at Rewa in Madhya Pradesh and Churk, Chunar and Sadwa in Uttar Pradesh. The deal was struck at an enterprise value of ₹2,850 crore and is expected to close within two weeks of execution.

The acquired assets from Jaiprakash Associates include 5.2 MnTPA of cement capacity and 3.3 MnTPA of clinker capacity. The package also covers 99 MW of thermal power capacity and railway sidings at Rewa, Chunar, and a common siding at Churk. This infrastructure gives the acquisition immediate operational utility beyond just production tonnage.

The transaction has a long backstory. Dalmia Cement had originally entered into a framework agreement with Jaiprakash Associates in December 2022, covering the sale of these business assets along with a long-term clinker supply arrangement. However, before the deal could be completed, Jaiprakash Associates was admitted to insolvency proceedings under the Insolvency and Bankruptcy Code. The earlier agreements could not be consummated as a result.

In an official statement, Puneet Dalmia, Managing Director & CEO, Dalmia Bharat, said, “I am very excited about addition of these assets in our portfolio. This serves as a great strategic fit for Dalmia. It helps us move forward in our journey to be a pan India player and provide a strong head start to serve the high potential markets in Central region. I am optimistic that the expansion potential of these assets along with close proximity with Dalmia’s captive mines will help us create a capacity hub for the future”.

Following the approval of Adani Group’s resolution plan for Jaiprakash Associates under the IBC framework, Dalmia approached the new management to revive discussions. The fresh Business Transfer Agreement was executed to settle all pending disputes, legal proceedings, and arbitration matters arising from the original framework agreement with Jaiprakash Associates.

Expanding market reach

Dalmia added, “Our familiarity with these assets under the earlier tolling arrangement gives us a deep understanding of the facilities and helps us establish strong connect with channel partners and vendors. We believe that this will help us in faster ramp up of capacities and quicker inroads into the market. As we look forward, I am very confident that we will be able to leverage the strengths of Dalmia to operate these assets in a manner where we can maximise value creation for all our stakeholders.”

With the addition of these plants, Dalmia Bharat’s total installed cement capacity will rise to 54.7 MnTPA upon consummation. The company has further expansion projects underway at Belgaum, Pune, and Kadapa, which are expected to take overall capacity to 66.7 MnTPA by Q2 to Q3 FY28.

The Central India location of the Jaiprakash Associates plants gives Dalmia Bharat faster access to markets in Madhya Pradesh and Uttar Pradesh than a greenfield build would have allowed. The company also cited debottlenecking and brownfield expansion as near-term opportunities at the acquired sites. Dalmia Bharat said the assets were expected to contribute positively to EBITDA and overall returns, given the pricing environment in the region and the company’s cost structure.
