Nitin Vyas, Managing Director and CEO, Beumer India, talks about how technology is the driving force behind the innovations in packaging, which will ultimately lead to more sustainable solutions and better efficiency.

Tell us about the loading systems and their impact on the energy efficiency of the cement manufacturing process.
If you break down the cement manufacturing processes into the raw and final product stages, about 25 per cent cost is sitting in the loading and packaging areas, which is part of the overall logistics. This is one of the most inefficient systems in the cement industry in the world, while the most efficient manufacturing systems are sitting in India. Unfortunately, a lot of focus has not come on the packing, loading and distribution of cement. Our machines not only function with respect to electro-mechanical loading efficiency or energy efficiency, they also are fully automatic. So, without any human intervention, a full truck can be loaded within 60 minutes. About 60 such machines are operational in India.
Looking at the larger picture and speaking about sustainability, our cement bags are a problem. They have a high porosity. The only two countries using these bags are India and China, where China will stop using these bags going forward as they are huge pollutants. When the bag is thrown, a lot of dust is generated. The cement industry needs to become responsible and not look at saving a miniscule amount of money per bag and rather look at the bigger picture and save the environment. Approximately Rs 2 per 50 kg bag needs to be spent to improve the quality, which will result in a better environment and better health conditions for the loader as well.
If I look at the macro numbers, India’s overall logistics cost is around 14 per cent of the GDP, whereas a developed nation’s overall logistic cost is up to 10 per cent. We are aspiring to achieve these numbers. However, the cement industry holds a logistic cost of 25 per cent, which is very high. Therefore, going forward, packing, distribution etc need to be considered to bring down this logistics cost. Sustainability needs to be created end-to-end.
The United Nations has given sustainability goals and the cement industry needs to benchmark against the same as a measure for their sustainability goals. We need to look at sustainability not only from the view of energy efficiency but as the upliftment of a society and environment. For me, in a packaging plant the word society refers to the workers. The economic benefit lies in the reduced logistic cost and a lot more. Sustainability needs to be looked at in a total framework, only then it can be achieved.

Do you think the industry experiences a gap in policies and regulations in the packaging arena?
There are no hard policies for packaging. There are no strict regulations on what kind of bags need to be used for packaging, what is the pollution limit in a packing plant etc. Sustainability is treated as fashion in today’s time, but it needs to be looked at more seriously, especially in the packaging and logistics domain.
We are hoping to implement more policies in the near future and there will be more transparency in policy and process in the days to come. Sustainability needs some push from the government, but eventually the onus is on the cement manufacturers to
follow through.

What is the role of technology in preventing wastage in packaging?
Anything that needs to be improved, needs to be measured. If you do not measure, you don’t know where you are standing. For example, your machine is supposed to produce 100 tonnes of cement in an hour, but in reality, it despatches only 80 tonnes in an hour, which should not be a satisfactory measure.
When the machines are technologically and digitally enabled, and the processes around them are made intelligent, too, then the measures are correct and precise. For a machine, system or line, manufacturers must measure Overall Equipment Effectiveness (OEE), to make it more efficient. This measurement will have an economic benefit, preventing wastage, by maximising the usage of the asset.
This enabling can work wonders in a cement packaging plant. For example, when a truck comes into the yard, enable it digitally by having a RF card, which the driver can scan and get to know his parking location and loading time. This saves time of filling out forms, reduces manual errors and saves cost. The truck can further get attached to machines, where packed bags can be loaded in a set weight and amount to have the most optimised loading of cement bags that can be despatched. Thus, technology prevents wastage of product, and it brings efficiency in terms of time and cost.

How important is data in building the kind of technology described by you?
Humans were originally hunters and gatherers. Our tools were bows and spears that were used for hunting. Then came the agricultural and industrial age when land was fuel and steel and coal were fuels, respectively. In today’s era, the digital age, data is the new fuel. Some of the data driven industries are richer than countries all together, because the new fuel for the economy is data. The first step to using data efficiently is to harvest it. Data is all over the place and data points need to be identified that should be harvested. People who use machines should understand the data points. Once the data is harvested it needs to be structured and put into categories and then start using it.
We do big data analytics for our machines. The objective is to improve the quality and efficiency of the machine. Data gives an opportunity to serve the existing market and improve existing machines while showcasing an opportunity to give economies of outcome. Thus, data is a powerful tool and one needs to identify and use it judiciously for their business and machines. It helps us better our technology by providing insights into the gaps as well as opportunities in the cement packaging sector.

What kind of innovations can be expected from your organisation in the near future?
We are working on a packaging machine that has a digital service attached to it. It comes with a smart glass, which will be given to the customer. So, whenever there is a breakdown or need for repair, there will not be a need for some person to come in. The personnel at the plant can wear these glasses. They have a camera and a screen that displays manuals and instructions. They can be heard and there is a facility to speak for help as well. All our machines are equipped with remote connectivity, which allows experts at the back office to take control of the machine and the person at the plant can show what is happening and get real time repair solutions, thus, saving on time and preventing longer downtimes.
This is one of many digital technologies that we plan to implement with our projects. For example, whenever we had a brown field on our existing plants, typically surveys were done manually, which used to take days. Now we are implementing 3D laser scanners, which will speed up the process at the plant. It beams the lasers around and with that we get the entire topography of the area, surface details and all required details to make modifications to our systems. All our machines now come digitally enabled. We also have apps to measure overall equipment effectiveness for plants and units to be more effective.

“There’s no waste in India; everything is wealth,” was the thought-provoking idea that came from Dr Mohapatra, DG, NCCBM, as he shared his views on ‘Circular Economy and Sustainability’ at the recently concluded 8th Indian Cement Review Conference. The questions he raised and the ideas he presented were enriched with his decades of experience of working on research, development and analysis of alternative raw materials and renewable fuel for the cement industry. He highlighted the struggles in manufacturing blended cement and the opportunities that are available for its use. Finally, he suggested ways to ensure that each manufacturing plant falls within the gamut of a circular economy.

On his part Dr Sriharsha Reddy, Director, IMT Hyderabad, elaborating on ‘ESG – Green Financing: A new opportunity for the cement industry’, brought to light a number of important issues pertaining to fund procurement through traditional methods and the challenges therein.

Highlighting his views on carbon capture and its benefits for the cement manufacturers, Saurabh Palsania, Executive Director and Group Commercial Head, Dalmia Cement (Bharat), underscored the need to implement innovative technology and most importantly a proper strategy, in order to revolutionise the efforts towards net zero emissions. “Carbon capture, utilisation and storage (CCUS) is an investment-intensive process that also requires a commitment of time and labour. Keeping all these factors in mind, cement companies need to chart out an effective strategy to incorporate CCUS into their eco systems, ensure purity of the captured carbon and channel it towards predetermined activities for its optimum utility,” he said.

Pratap Padode, Founder & President, FIRST Construction Council, summarised the challenges faced by the Indian cement industry as well as the growth opportunities it presented for manufacturers in terms of technological innovation and capacity building. He supported his opinions with statistical findings and his in-depth knowledge about the Indian cement and construction industries.

Several discussions from the event highlighted several critical aspects of the cement industry.

ESG – Green Financing: A new opportunity for the cement industry

The cement industry has made progress in reducing energy consumption and power usage, but the challenge now lies in reducing carbon emissions. With breakthrough carbon capture technologies and solar calcination of limestone, the industry can work towards achieving zero CO2 emissions. However, the economic value of carbon capture needs to be explored, with government support through carbon labelling, trading, and green funds. Other solutions such as non-contact grinding and heat recovery from kilns can also be explored to bring emissions to zero. The industry can achieve sustainability and low carbon footprint with digital transformation and well-planned processes. To finance green initiatives, traditional lending institutions such as banks are now considering the economic value of eco-friendly practices. However, long-term loans remain a challenge, and other lending institutions such as venture capitalists and government grants need to be explored.

Demystifying digitalisation and maximising the value chain impact

Digitalisation is crucial in optimising all stages of cement production. Industry 4.0 has provided tools that help determine the desired product quality, which is vital in meeting customer demands. As the importance of ESG continues to grow, digitalisation can help improve processes and reduce environmental impact. Transparency is also key, and a cloud-based platform can facilitate this. Automation at the plant level is vital for both efficiency and safety. However, it is important to remember that profitability is also essential for sustainability. Therefore, implementing digital tools and automation must be done with a focus on achieving profitability without compromising on sustainability.

Innovative supply chain strategies in the cement industry

Innovative supply chain strategies are crucial for the cement industry to remain competitive, with logistics and transportation being at the forefront. Industry experts discussed that the key to cost efficiency lies in innovation in first and last mile connectivity. However, logistics should not be viewed as merely a commercial function, but rather as a technology function. By investing in technology, cement manufacturers can drive the supply chain in a much better way, enabling them to evaluate processes from a revenue angle rather than just cost.

Industry experts also agreed that logistics is the only differentiator a cement company can have today, rather than cost or quality. As such, it is essential for cement manufacturers to explore non-renewable sources of energy to address the energy demand for distribution. Automation is also considered a key element for future logistics solutions. With these innovative strategies in place, the cement industry can increase efficiency and sustainability, which in turn can positively impact the bottom line.
On his part, Gaurav Gautam, Head of Sales, Beumer Group, highlighted the innovations in material handling systems that the is undertaking in order to make the movement of finished products smoother along the supply chain. The company specialises in tailor-made intralogistics solutions that help maximise productivity of cement companies.
