March against asbestos

Published

Shares

Though its use is banned in most countries, the asbestos industry continues to thrive at the cost of putting millions of people at risk.

Asbestos has an uncanny habit of repeatedly making headlines. Recently, the Drug Controller General of India issued a show cause notice to Johnson & Johnson for its alleged use of asbestos in its talcum powder. In February this year, authorities imposed a fine of more than $40,000 after asbestos was found in the construction of a school in Michigan, usa. In New Zealand, a maternity home was demolished in March in Taupo District Council after officials detected asbestos materials. Asbestos has been used for different purposes since prehistoric times, but today the campaign against its use is building up, as exposure can lead to a wide range of diseases. When asbestos materials are damaged or broken during processing, the tiny fibres become airborne and can be easily inhaled at a significant rate. Once inhaled, asbestos fibres lodge in the lining of the throat, lung, or stomach, causing cells to mutate and become cancerous.

Well-documented effects
According to the World Health Organization (WHO), about 125 million people are directly exposed to asbestos in their workplace annually. More than one million workers die each year from an asbestos-related disease. In 2004, asbestos-related diseases such as lung cancer, mesothelioma and asbestosis from occupational exposure resulted in more than 1.5 million Disability Adjusted Life Years.

That’s why 60 countries have banned the use of this toxic material. Though the Supreme Court of India banned its use on January 21, 2011, it is still being widely used across India. The country uses about 3,50,000 tonnes of asbestos annually and the industry is growing by 12 per cent annually. More than 50 factories use chrysotile, also known as white asbestos, as an ingredient in cement roofing sheets, wall panels, pipes and other products. Asbestos deposits are found in Andhra Pradesh, Bihar, Jharkhand, Karnataka, Rajasthan and Manipur. Workers at cement factories in Ahmedabad, Hyderabad, Coimbatore and Mumbai are suffering from the lethal effects of asbestos. In these factories, the prevalence of asbestosis varies between 3 per cent and 5 per cent. Worse, India continues to import asbestos to be used in cement roofing sheets, cement piping, friction materials, textiles, insulation and even railways and armed forces. Moreover, asbestos products carry no health warning labels and trade unions have no mandate to prevent asbestos-related disease at workplaces. In fact, asbestos related-diseases are never diagnosed but simply labelled as tuberculosis or bronchitis. As long as the state governments and Union Territories have no mechanism to prove that lung cancer deaths and other severe conditions are being caused by asbestos exposure, the Indian asbestos industry could not care less about global efforts to completely eliminate this deadly material.

Trials continue
Russia remains the world’s largest producer of asbestos. The major mines are situated in Asbest, a city located on the eastern slopes of the Ural Mountains, once known as the "dying city" due to its high rate of lung cancer and other asbestos-related conditions. Russia provides most of the asbestos to the world market, including for the US.

Ironically, its use is legal in the US. "By allowing asbestos to remain legal, the Trump administration would be responsible for the flood of asbestos imports from Russia and other countries into the US, as well as the wave of illnesses and deaths that will continue for years to come," says Linda Reinstein, CEO and Co-Founder of the Asbestos Disease Awareness Organization, a non-profit based in California, USA. The legal claims for injuries from asbestos exposure in the US involve more plaintiffs, more defendants and higher costs than any other type of personal injury litigation. By the beginning of 2001, about 6,00,000 individuals had filed lawsuits against more than 6,000 defendants. The total amount that defendants and insurers have spent on resolving claims, including legal costs, is estimated to be $54 billion. The victims say they suffer from lung problems caused by repeated exposure to asbestos on their jobs.

The cases with the greatest potential liability involve mesothelioma and lung cancer. How much money can be awarded in a lawsuit depends on many factors, such as the medical evidence that confirms the diagnosis, the degree of injury, the actual and potential losses, and the financial resources of the company liable for the asbestos exposure.

Since the 1980s and continuing through the present, a number of companies who were defendants in asbestos litigation quickly sought to limit their losses by filing for bankruptcy protection. Specifically, this is a legal process which allows a company to re-organise in a bankruptcy proceeding, put money aside for present and future asbestos liabilities, and, then exit bankruptcy and continue to do business. For instance, Johns-Manville declared bankruptcy decades ago and set up a bankruptcy trust to pay victims of asbestos-related diseases. Soon the company exited bankruptcy and continued to operate as a business with products that can be seen in building supply stores across the country.

As one of the most energy-intensive industries, cement manufacturing faces growing pressure to optimise power consumption, reduce emissions and improve operational reliability. Technology providers like Innomotics India are enabling this transformation by combining advanced motors, AI-driven digital solutions and intelligent monitoring systems that enhance process stability and reduce energy costs. From severe duty motors built for extreme kiln environments to DigiMine AI solutions that optimise pyro and mill operations, Alex Nazareth, Whole-time Director and CEO, Innomotics India, explains how the company is helping cement plants achieve measurable energy savings while moving closer to their sustainability goals.

How does your Energy Performance Contracting model typically reduce power consumption in cement plants—e.g., MWh saved?
Our artificial intelligence-based DigiMine AI Pyro and Mill solutions developed specifically for the cement industry, supports our customers in improving their process stability, productivity and process efficiency. In Pyro, this is achieved by optimising fuel consumption (Coal / AFR), reducing Specific Heat Consumption and reduction in emissions (CO2, SOx and NOx) through continuous monitoring of thermodynamics in pyro and recommending set-points of crucial parameters in advance for maintaining stable operations.
Within the mill, this is achieved by improving throughput, reduce energy / power consumption and maintaining stable operations on a continuous basis. Our ROI-based value proposition captures the project KPIs like reduction of coal usage, increase of AFR, reduction of specific heat consumption (Kcal / Kg), reduction of specific power consumption (KWH / tonne), reduction of emissions, etc., by a specific percentage. This gives clarity to our customers to understand the investment vis-à-vis savings and estimate the recovery time of their investment, which typically is achieved within one year of DigiMine AI Pyro and Mill solutions implementation.

What role do digitalisation and motor monitoring play in overall plant energy optimisation?
Motors are being used extensively in cement production, and their monitoring play crucial role in ensuring continuous operation of applications. The monitoring system can automatically generate alerts for any anomaly / abnormalities in motor parameters, which allows plant team to take corrective actions and avoid any major equipment damage and breakdown. The alerts help maintenance team to plan maintenance schedule and related activity efficiently. Centralised and organised data gives overview to the engineers for day-to-day activities. Cement is amongst the top energy intensive industries in comparison to other industries. Hence, it becomes critically important to optimise efficiency, productivity and up-time of plant equipment. Motor monitoring and digitalisation plays a vital role in it. Monitoring and control of multiple applications and areas
within the plant or multiple plants becomes possible with digitalisation.
Digitalisation adds a layer on top of OT systems, bringing machine and process data onto a single interface. This solves the challenges such as system silo, different communications protocol, databases and most importantly, creates a common definition and measurement to plant KPIs. Relevant stakeholders, such as engineers, head of departments and plant heads, can see accurate information, analyse it and make better decisions with appropriate timing. In doing so, plant teams can take proactive actions before machine breakdown, enable better coordination during maintenance activities while improving operational efficiency and productivity.
Further using latest technologies like Artificial Intelligence can even assist operators in running their plant with minimal requirement of human intervention, which allows operators to utilise their time in focusing on more critical topics like analysing data to identify further improvements in operation.

Which of your high-efficiency IEC low-voltage motors deliver the best energy savings for cement mills or fans?
Innomotics India offers a range of IEC-compliant low-voltage motors engineered to deliver superior performance and energy savings, particularly for applications such as cement mills, large fans, and blowers. Innomotics has the complete range of IE4 motors from 0.37kW to 1000kW to meet the demands of cement industry. The IE5 range is also available for specific requirements.

Can safe area motors operate safely and efficiently in cement kiln environments?
Yes, safe area motors are designed to operate reliably in these environments without the risk of overheating. These motors have ingress protection that prevents dust, moisture ingress and can withstand mechanical stress. These motors are available in IE3 / IE4 efficiency classes thereby ensuring lower energy consumption during continuous operation. These motors comply with relevant Indian as well as international standards.

How do your SD Severe Duty motors contribute to lower emissions and lower cost in heavy duty cement applications?
Severe duty motors enhances energy efficiency and durability in demanding cement applications, directly contributing to lower emissions and operational costs. With high-efficiency ratings (such as IE3 or better), they reduce power consumption, minimising CO2 output from energy use. Their robust design handles extreme heat, dust and vibration—common in cement environments—ensuring reliable performance and fewer energy losses.
These motors also lower the total cost of ownership by reducing downtime, maintenance and replacement frequency. Their extended service life and minimal performance degradation help cement plants meet sustainability targets, comply with emissions regulations and improve overall energy management—all while keeping production consistent and cost-effective.

What pump, fan or compressor drive upgrades have shown approximately 60 per cent energy savings in industrial settings and can be replicated in cement plants?
In the cement industry, the primary high-power applications are fans and mills. Among these, fans have the greatest potential for energy savings. Examples, the pre-heater fan, bag house fan, and cooler fans. When there are variations in airflow or the need to maintain a constant pressure in a process, using a variable speed drive (VSD) system is a more effective option for starting and controlling these fans. This adaptive approach can lead to significant energy savings. For instance, vanes and dampers can remain open while the variable frequency drive and motor system manage airflow regulation efficiently.
