However, it seems the world just can’t get enough of water. Global water demand is projected to increase 55 percent by 2050. Most of the demand will be driven by the agriculture industry, which currently makes up 70 percent of freshwater consumption, but is projected to grow another 69 percent to meet the food demands of the growing population. New-growth industries will put additional pressure on freshwater supplies. For example, water used to cool power stations is projected to increase by more than 20 percent by 2055 and water demand from the manufacturing industry in developing nations will grow by 400 percent by 2055. Unfortunately, 97.5 percent of earth’s surface water is inadequate for human use.

The growing demand is putting heavy pressure on current water supplies that appear to be shrinking due to global warming and climate change. As a result, there have been extensive efforts by individuals and households to conserve and recycle water. However, in major cities around the world, water is wasted before it even reaches people’s taps.

Water leaking through the cracks

In the U.S., about 2.1 trillion gallons of water slip through the cracks, literally, each year, or about 6 billion gallons of water per day. The ancient water infrastructure throughout the country is full of leaking pipes, cracked mains and broken meters.

For example, the largest water filtration plant in the world, Jardine Water Filtration Plant, is located in the city of Chicago and pumps out purified water to about 5 million residents via thousands of miles of pipes. However, about 22 billion gallons of water leak through old pipes and broken water mains in the city every year. In Philadelphia, the Water Department pumps out 250 million gallons of purified water daily to nearby residents, but more than 60 million gallons are lost through the pipes every day.

In Canada, home to some of the most abundant supplies of freshwater, there are cities with 35 to 45 percent water loss. Ontario, for example, has outdated and leaky pipes responsible for the loss of about  CAD 700 million per year in wasted drinking water.

In the UK, about 872 million gallons, or 20 percent the nation’s treated water supply, leaks through old pipes before it reaches residents. This is 62 million gallons more per day than water loss rates from a decade ago, showing the severe consequences aging pipes can have.  

Faulty water pipes

The biggest problem with water systems around the world is simply their age. They were built ages ago, often with insufficient materials and outdated technology, and now, they’re too expensive and extensive to repair or replace.

However, old pipes can pose a number of problems. Besides the gallons of wasted purified water, an outdated water system can pose major health risks. In the U.S., 1 in 4 people drinks unsanitary water due to insufficient water infrastructure. It has already been proven that contaminants can enter the water system through leaks that are most often caused by corrosion and material defect.

Water pipes installed decades ago are traditionally made of cast iron and laid on wooden blocks or rocks. Such pipes are highly corrosive and most susceptible to damage. Also, a well-functioning pipe keeps contaminated water out with pressure from mains that forces water out of minor cracks, but not in. Over time, damage to a certain section of a pipe can cause this pressure to drop, and groundwater often finds its way in through cracks.

Making it right with steel

The ideal solution for outdated, faulty water pipes would be to replace them with new ones equipped with the latest damage detection and repair technologies. However, such projects are not only expensive, but a city’s water system is often politically, regionally and physically intertwined with other entities, making it difficult to take on such a mammoth task.

Thus, cities opt for isolated repairs instead, either placing a stainless steel clamp over the damaged area or inserting a smaller stainless steel pipe inside the existing, cracked pipe. Stainless steel is the most common material for repairing and replacing outdated cast iron, concrete and lead pipes due to its excellent strength and resistance to corrosion. Higher grades of stainless steel, such as POSCO’s PossSD, can also resist high levels of pressure and are naturally resistant to microbes. Stainless steel can also be manufactured to withstand extreme temperatures.

Major cities such as Tokyo, Seoul and Taipei are undergoing massive projects to replace the majority of their water pipes with stainless steel to ensure safe and abundant drinking water for residents. For other cities, repairing leaky pipes with stainless steel will save millions of dollars currently leaking through the pipes and prevent illnesses associated with contaminated water. As the global demand for water continues to grow and fresh water supplies continue to shrink, conservation is becoming more important than ever, ensuring that stainless steel will play a vital role in water pipe repairs and replacements for years to come in efforts to correct and maintain the system that serves the basis of all human activities.

Prime Minister Modi revamped India’s economy with his “Make in India” initiative. (Source: LinkedIn)

Most notably, Prime Minister Modi launched the “Make in India” initiative in September 2014, showing his resolve to revamp the manufacturing industry in India. Under the initiative, domestic as well as foreign companies are encouraged to manufacture their goods in India with the goal of increasing the makeup of the manufacturing industry to 25 percent of GDP by 2025.

At the heart of the initiative is the government’s efforts to ignite the steel industry. The National Steel Policy (NSP) 2017 declared that India will become self-sufficient on domestic steel supplies by increasing its steel production capacity from 122 Mt in 2015 to 300 Mt in 2030. However, the steel industry currently only makes up 1.04 percent of the country’s GDP.

Challenges Ahead for India’s Steel Industry

Despite India’s promising potential and robust government support, the steel industry has not met the government’s high expectations and growth has been modest. According to researchers in volume 4 of the Asian Steel Watch, there are deep structural flaws within India’s steel industry that need to be addressed before the country can reach its full potential.

One of the industry’s biggest challenges is its growing debt – In 2016, the steel industry surpassed INR 3 trillion in debt. Most of the country’s steel and infrastructure projects are financed by the government. What India needs is more private sector involvement, but private players are hesitant due to complex regulations, a lack of business models and no guarantee on returns on investment (ROI). The government has also been slow to secure FDI because, over the years, India’s steel industry has displayed poor planning and management of projects as well as a mismanagement of funds.

Another major challenge has to do with India’s natural resource management, as mining companies do not have fair access to the country’s abundant resources. The mining industry is subject to heavy tax burdens including the royalty, local area development tax, forest development tax and much more as it is a profitable business for the government. Plus, the costs of meeting international environmental standards are passed directly onto mining companies. Thus, the price of iron ore and other minerals do not reflect the abundant supplies available, and the higher prices ripple into the steel industry.

Moreover, the government regards the steel industry as the backbone of India’s economy, but in reality, the times are changing.

Technological advances in the manufacturing industry is making the steel production process more efficient and less labor intensive. (Source: South China Morning Post)

In the past, 70,000 workers were required to produce 1.5 Mt of steel. Today, it takes about 3,000-4,000 workers to make 5 Mt a year. The steel industry is just not what it used to be in terms of the positive effects it had on the economy as a whole. The industry requires intensive capital and the only way it will survive is with low labor costs and maximum manpower productivity.

India needs to take full advantage of the country’s abundant resources and capitalize on its competitiveness to reach its full potential. In order to do so, India can start by examining other steel industries that served as the main driver for national economic growth, such as Korea’s.

Takeaways from Korea

After the Korean war in 1953, Korea had to build its economy up from scratch. Like India, the government chose to stimulate its steel industry and spent its war reparations payment from Japan to build POSCO’s steel mill in 1969. Since then, the state-led steelmaker has been a primary engine for Korea’s miraculous economic growth.

The construction of POSCO’s headquarters began in May 1968.

So how did Korea manage such growth?

The government allocated much of its resources to infrastructure construction for efficient logistics and implemented policies to support the mutual growth of steel and steel-consuming industries. Moreover, the government practiced protectionist trade policies long enough to get Korea’s steel business on its feet, then supported a market-driven business model.

The government also kept a close watch on supply and demand forecasts and updated its supply policies timely and accordingly. Factors such as demographic changes, industrialization patterns, urbanization and labor costs should be examined holistically to prevent the gap between supply and demand from increasing too much. For example, in 2010, the Korean government implemented capacity expansion policies that resulted in oversupply and a prolonged recession. This was because policymakers failed to diagnose the symptoms of the mid to long-term steel demand forecasts that showed sluggish demand. Since then, Korean policymakers keep close watch on such measures to update the country’s supply policies.

Finally, the Korean steel industry invested heavily in knowledge accumulation and R&D to wean off of Japan’s technical support and become an exporter of steel technology.

POSCO is now a leader in steel production technology.

Compared to Korea, India has an advantage in almost every aspect. The country’s per capita steel consumption is still low and the booming population will drive demand in steel-related industries. With much room for growth, the Indian steel industry can expect to see accelerated growth when paired with the right policies and government support.

What’s more, manufacturing is no longer a rigid industry that produces uniform, one-sided goods. There is constant communication between customers and businesses for hyper-customization. Not only that, machines and products communicate within a smart factory, and factories exchange data with other factories. Manufacturing is no longer limited to production plants. Moreover, the data generated in the manufacturing process is combined with customer information, and a new service can be created. This combination of manufacturing and services is resulting in creation of added value. In the midst of such drastic change, how can companies stay competitive?

Staying Competitive Through Connection and Convergence

Global manufacturing companies are at the forefront of the 4th Industrial Revolution, as evident in their smart factories. A smart factory collects data generated from the production process using ICT technology, and the system controls all processes from material input to the final product. This has led to flexible production systems with the ability to make various products in one factory or to expand the range of products on the basis of connectivity. Typically, when a company builds a smart factory, it can improve productivity by 20 to 30 percent. A 20 percent improvement in efficiency in the manufacturing sector is a significant, outright increase in global competitiveness.

If the productivity of a plant can be improved through smartization, it is important to also think about connectivity with the ecosystem that exists outside of the plant. Once a smart factory is built, all the data from customer orders to production and delivery are collected in a system via sensors. The customer, product and production data create meaningful connections with each other and provide extensive insight. Examples of added value creation through meaningful connections include hyper-customized goods, data-driven after-sales services to customers and collaboration among companies connected within the smart factory’s external ecosystem. Such advancements will lead greater product quality, production stability as well as shortened delivery times between value chain suppliers.

The Adidas Speed Factory and GE Brilliant Factory are examples of successful smart factories. Adidas customers choose the materials, colors and design of their sneakers, and have them manufactured and shipped within 24 hours in an automated factory.

GE has built a system that can produce all of their widely-diverse products in one factory. When the factory receives customer orders, it operates in a flexible production system which starts with the necessary raw materials, inputted by the automated scheduling system that controls the entire production process, including the final distribution system.

The Future of Manufacturing

Overall, the adoption of innovative changes in the manufacturing sector is likely to progress from lighter industries to the heavy industries, from B2C to B2B sectors. Small plants, quick manufacturing and B2C companies can more readily adapt to rapid technological and market changes. On the other hand, heavy industries like steel and B2B companies with continuous and heavy manufacturing, large production volume and numerous linked companies are likely to be slower to adapt to changes.

For example, adapting to the changes of the 4th Industrial Revolution in the steel industry may be slow, but it is inevitable. What’s more, the long-term adaptation process is more likely to be systematic and deliberate.

As a leading company in the global steel industry, POSCO is pursuing a long-term, systematic “Grand Design” to reinvent its systems to align with the changes of the 4th Industrial Revolution.

First, POSCO built a pilot smart factory in their steel mill, Gwangyang Steelworks, in 2015 that is currently in operation. The company used IoT to collect big data on site, analyze it in real time and build a smart factory that enables optimal control through AI and self-learning. As a result, the Gwangyang Steelworks is reaping the benefits of a smart factory not only in cost reduction but also in improved steel quality, minimized malfunctions and a safe and stable production environment. This year, POSCO plans to expand and apply smart factories to all of its production processes.

POSCO built a smart factory in Gwangyang Steel Mill.

Smart factory application throughout the entire steel mill will improve overall efficiency through a flexible production system. In addition, the factory will be able to respond directly to various customers in real time based on platform construction with customers within the connected ecosystem. The customized characteristics and design of the steel grade for each customer can be applied to production in real time.

SEE ALSO: How Factories Produce Steel – the Smart Way

Ultimately, a smart ecosystem that links manufacturing, processing and distribution with customer input will lead to a new, innovative ecosystem within the steel industry. In Europe, some companies are experimenting with material libraries and steel distribution platforms. The material library displays a variety of materials for customers to see, touch and test the workability and performance of the materials, and get information about the characteristics, design and delivery times through the order platform. Customers can designate the shipment date on the spot. This will be one of the new promising business models that steel and other material companies will strive towards in the coming future.

POSCO’s Grand Design includes a step-by-step approach to smart factories to expand the use of IoT, AI and Big Data in its production systems. To this end, POSCO ICT has developed PosFrame, a standard software platform that collects basic data of production processes and collectively manages, controls and analyzes the information.

POSCO uses its software platform, PosFrame, for data collection and analysis.

When the software becomes standardized and reliable enough to extend to other sectors, it will be applied to other business areas such as energy and construction, as well as to POSCO’s affiliates.

Manufacturers will have to take into account the heavy production environment, the slow industrial change cycle and the complexity of related industries and affiliates to implement the most effective, long-term, systematic upgrades to its production systems. This will result in a brand-new production and business model for manufacturing companies that will align with the new environment of the 4th Industrial Revolution.

Here’s a look at how steel is produced in a steel mill or factory, and what the “smartization” of steel factories will look like.

So, how is steel made?

Iron Making

To make steel, manufacturers first need molten iron. Molten iron comes from two raw materials; iron ore and coal. Iron ore is converted into sinter ore in a sintering plant and coal is converted into raw coke using a coke oven. The processed materials are poured into a blast furnace where hot air reaching 1200℃ is blown in from the bottom through tuyeres, causing a chemical reaction. This process oxidizes the coke and reduces the sintered ore, creating molten iron.   

Steelmaking

In the steelmaking stage, the molten iron is transported to the steel making plant via a torpedo car, where the liquid is poured into a converter. Then, oxygen is blown into the converter to burn off all the impurities. All that is left is pure molten steel.

Continuous Casting

This is where steel finally becomes solidified into different shapes such as slab, bloom and billet. Liquid steel is poured into molds and cooled as it passes through a continuous casting machine until it solidifies into the desired shape.

Rolling Process

During the rolling process, steel is heated once more to achieve various sizes and thicknesses. Steel slabs are heated to over 1100℃, then pass through rolling machines. This results in hot-rolled coils that can be shaped for different uses such as thick plates. They can also be processed into long, wire-shaped rods for billets. Often, the hot-rolled coils are rolled at room temperature for cold-rolled coils. Cold-rolled coils can be fabricated to produce galvanized and electrical steel products.

“Smartizating” these processes will involve converging IoT, Big Data, and AI to connect the different facilities, IT systems and workers in order to collect and analyze data for optimization.

POSCO is “smartizing” the steel-production process

POSCO is a steel company looking to lead the industry in adopting smart factories. CEO Kwon Ohjoon made “smartization” one of the 4 key priorities for POSCO starting back in 2014, and Kwon will continue to increase those investments.

In 2016, POSCO established its Smart Solution Council in order to research AI, big data and IoT applications. In the same year, POSCO ICT’s smart factory platform, PosFrame, was completed and installed in POSCO’s Gwangyang Steel Mill. PosFrame allows engineers to collect and monitor big data. So far, the company has saved over USD 14 million by incorporating the new technology in its production practices.

Here are some other features of POSCO’s Smart Factory.

POSCO’s Smart Blast Furnace

The Pohang Blast Furnace No.3 became a smart furnace in 2017, following a 102-day repair period. The furnace is now equipped with automated sensors that monitor and control its internal conditions using AI technology. Smart sensors monitor the blast furnace for factors like raw material quality and ventilator status, preventing breakdowns and ensuring a much longer lifecycle.

SEE ALSO: Will Artificial Intelligence Lead to Breakthroughs in the Steel Industry?

Worker Safety

Smart sensors can be used for more than just process monitoring. The company is working toward a full implementation of smart sensors for safety purposes, using IoT to create a better working environment.

Steel manufacturing involves high temperatures and high pressure levels, which is dangerous for workers who come in close contact with the equipment. With smart sensors monitoring all of the factory information, workers will instead be monitoring operation from a safe distance.

Workers in POSCO’s smart factory wear smart sensors for safety.

Wearable sensors, in conjunction with factory smart sensors, will be able to detect if and when workers are approaching potentially dangerous areas, and will alert them. These sensors will also detect and alert with regards to any impending accidents, or life-threatening situations like gas leaks, explosions, or fires.

Also, dust, sulfur, and nitrogen compounds will be removed via a high-plasma method, creating an eco-friendly steel plant and a healthier environment for workers.

POSCO will continue to add more smart features to its steel mills to increase efficiency, safety and sustainability. In efforts to learn and implement new technologies, POSCO CEO Kwon Ohjoon visited GE’s smart factories to learn about their technology earlier this year. POSCO also held the 2017 Smart POSCO Forum to share its insights with clients and affiliates, all as part of its expanding smartization efforts.
