For several years, the steel industry has taken measures to eliminate these issues, and the effort is ongoing. What are some of the key issues surrounding the industry’s air quality management? POSCO Newsroom presents worldsteel, “Air Quality Management.”

The steel industry recognises the importance of the issues surrounding emissions to air and their impact on ambient air quality, human health and the environment.

For decades, the steel industry has taken measures to address these issues, thereby significantly and demonstrably reducing emissions per tonne of steel.

Steel, whether produced via the integrated, direct reduced iron or electric arc furnace route, requires the transport, storage, handling, heating and transformation of raw materials.

All these processes have the potential to generate emissions to air *, primarily in the form of dust (or particulate matter (PM), sulphur dioxide (SO2), and nitrous oxides (NOx). Other emissions generated in small quantities include dioxins and heavy metals, typically attached to dust particles.

Today, all steel plants are subject to environmental regulation, which set requirements to restrict emissions to air. This regulatory framework is translated into an environmental permit (or licence to operate), which establishes plant-specific Emission Limit Values (ELVs) covering the primary emissions to air, dust, SO2, and NOx, and in most cases other
emissions.

The environmental permit also sets monitoring requirements and it is common for steel plants to have additional requirements within the permit, such as maximum production capacity, emission ceilings for specific emissions, taxes or fees on emissions or specific reduction targets.

l Emissions from Stacks versus Diffuse and Fugitive Sources

Stack emissions are released at height from identifiable sources (point sources) and are dispersed in the atmosphere. Diffuse and fugitive emissions (non-point sources), contrary to stack emissions, originate from an area, such as a stockpile or a road.

Stack emissions are managed using a variety of controls, such as beneficiation (i.e. removing potential contaminants before further processing), yield/process optimisation (‘more with less’), combustion control, abatement technologies (i.e. bag filters, electrostatic precipitators (ESPs), wet scrubbing systems, activated carbon adsorbers, cyclones, mist eliminators, etc.), source monitoring, incident investigation, plant inspections, source modelling and targeted plant maintenance regimes.

Stack emissions from the steel industry are managed to be well below prescribed ELVs. Exceedances are infrequent and occur in most cases during process disturbances. In these cases, authorities are informed and investigations carried out to identify the root cause, prevent recurrence and drive continuous improvement.

Emissions from iron and steelmaking operations, including cast house floor emissions from blast furnaces, are controlled via secondary dedusting systems (i.e. bag filters, wet scrubbers, ESPs, etc.) with a collection point inside the building. Occasionally, for safety reasons, the flaring of process gases is required. In this case the gases will have been filtered beforehand.

Diffuse emissions are mainly associated with material handling, stockpiling and transport activities. A variety of controls are used to manage potential emissions from these activities, such as minimising volumes of material stored, stockpile design, watering of stockpiles and roads, application of surface sealants, use of enclosures for bulk material storage, paving and sweeping of roads, dedusting of transport belts or use of closed belts, windbreaks/vegetation and video surveillance.

In addition to these measures, several tools are used to proactively manage emissions, such as weather alert systems, ambient monitoring, plant inspections/audits and risk/incident management systems.

Fugitive emissions, such as emissions generated from the roof of some buildings or emissions escaping from valves and evaporation of solvents are typically controlled and managed through maintenance and monitoring.

Diffuse and fugitive emissions are commonly regulated through the application of regional ambient air quality standards, which are based on an assessment of modelled or potential impact on the ambient air quality at selected ambient monitoring locations in the neighbouring area.

l Regulatory Framework

An environmental permit is a requirement for the operation of a steel plant. The permit is based on an assessment of the environmental impacts of
activities and most permits set ELVs in addition to defining monitoring and reporting requirements.

Environmental permits are typically reviewed periodically, or in case of production increase, construction of new facilities, new/revised environmental standards, or when new substances are identified.

• Environmental permits and ELVs must be based on sound science with respect to the potential risk to human health and the environment, and they need to be achievable.
• Environmental permits should never prescribe the use of a specific technology but should allow requirements to be met with a technology/practice of choice. To guarantee the smooth operation of the plant and the optimal protection of the environment, the permitting process must ensure legal and planning certainty.

l Holistic Environmental Assessment

Advanced abatement technologies require energy and other operational supplies to provide effective emission control. For example, wet dedusting technology requires significant amounts of water and electricity as well as chemical additives. To ensure an optimal environmental outcome, it is necessary to consider the impact of the prospective air emission abatement control technology on other environmental aspects (i.e. water pollution, waste generation/treatment requirements, energy requirements and greenhouse gas emissions), commonly known as the cross-media effects.

• When considering a suitable abatement technology for a specific emission source or production process, it is essential to take a holistic approach to the potential environmental impacts and consider the overall sustainability of the technology.

l Application of Emission Reduction Technologies

Every steel plant is unique, for example, in relation to geographic location, the proximity of sensitive receivers, the scale of operation and production processes. Therefore, a robust environmental risk assessment, including analysis of potential cross-media effects, is essential to ensure that identified emission reduction technologies are fit for purpose and sustainable for application at a specific steel plant.

Technical considerations should contemplate aspects such as the applicability to new and/or existing plants, specific operating conditions and types of raw materials and fuels.

• Since every steel plant is unique, it is essential to assess and ensure that identified emission reduction technologies are fit for purpose and sustainable for each application.

Stack emissions from power generation, industrial processes and the steel industry contribute to general background levels of air pollutants and form part of a larger set of physical agents found in the atmosphere. Emissions from natural sources such as forest fires, soil, pollen and sea spray also make up a large part of the background levels.

• Reducing emission generation from point sources improves regional air quality.

Diffuse and fugitive emissions, particularly dust emissions, are typically emitted close to ground level, and as such predominantly contribute to local air quality and tend to raise visual amenity issues.

Other emission sources impacting on local air quality include road traffic, transport, domestic heating, construction and demolition, bulk material handling and agriculture.

• Effective control of emissions closer to ground level drive improvements in local air quality.

l Monitoring of Air Emissions

The steel industry conducts extensive air emissions monitoring to follow up on permit requirements and identify opportunities for continuous improvement.

Monitoring in a typical steel facility includes source monitoring of emissions to identify potential sources of dust, NOx, SO2, and heavy metals. This monitoring combines extractive testing and continuous or online monitoring and reporting to the authorities.

Many steel plants also maintain, or support, broader ambient monitoring networks on the perimeter of the facility or in the neighbouring community of total suspended particles (TSPs), PM10, PM2.5, NOx, SO2 and sometimes heavy metals. Other types of monitoring include deposition monitoring and biomonitoring.

In addition, most steel plants have invested in air quality modelling and other established management activities such as targeted audits/inspections, video surveillance, environmental readiness and community hotlines.

These management practices are designed to determine the steel industry’s ambient air quality contribution, assist in identifying the sources of emissions and drive improvement.

l Health and Environmental Effects

Air pollution has recognised environmental and health effects. Air quality standards are therefore established to prevent, reduce or avoid adverse impacts on human health and the environment.

Through the application of advanced abatement technologies, comprehensive management practices and a drive for continuous improvement, the industry aims to minimise emissions to air and thereby their impact.

• The steel industry engages proactively and constructively with permitting authorities and its stakeholders to respond to emerging health and environmental issues.

l Going Forward, What Are Our Key Focus Areas?

Diffuse dust (dust from material handling, stockpiling and transport activities) is the most visible particulate matter generated by the steel industry. While significant technology and management improvements have been made in the past decades, managing diffuse dust remains a challenge.

Because steel plants are often surrounded by residential areas, either for historical reasons or due to growing rapid urbanisation, the steel industry needs to further engage with local communities to discuss any concerns they may have, leading to an ongoing partnership.

Another area of critical importance is the further refining of sophisticated air quality modelling systems (dispersion modelling), which can determine the share of steel industry activities on ambient air quality and demonstrate improvement over time.

* Emissions to air have the particularity of having a local or regional reach as opposed to CO2 emissions, which have a global impact, and are therefore not covered in this report.

They observed that the price of coking coal went from USD 75 per ton in February 2016 to USD 200 in December 2017, but it wasn’t a linear rise. In April 2016, the Chinese government implemented policies limiting the mining and production of coking coal, sending prices up to USD 300 per ton in just 2 months. Prices did eventually stabilize, but a series of natural disasters compromised supplies and logistics from major suppliers, leading to another rapid price increase.

Iron ore prices also had their ups and downs. At the beginning of 2016, the price for iron ore was  USD 41 per ton. Then, it reached USD 95 at the beginning of 2017, went back down to USD 57 in June, then shot back up to USD 70 in December 2017.

This price instability placed a heavy burden on steel producers and steel-consuming industries, making it hard to plan for the near and distant future. The following are a few of the factors that contributed to the capricious prices that will likely continue on into 2018 and beyond.

China environmental policy

Beginning in 2016, the Chinese government sought to close over 1,000 coal mines in just one year to cut the country’s production capacity by 60 million tonnes. This is part of the 5-year goal of cutting 500 million tonnes of surplus capacity.

Policies included switching to cleaner fuels and reducing mining-related working days from 330 to 276 days per year. Numerous small and medium-sized mines closed down as a result of the financial burden and domestic coal production was down 7.8 percent YoY.

As China is the biggest producer of coal and the third largest producer of iron ore in the world, global prices skyrocketed and the ripple effect was felt in markets all over the world. Due to the greater-than-expected domestic and global outcomes, the Chinese government eased some of its policies in November of 2016, bringing prices back down by about 50 percent. However, the government is scheduled to gradually enforce production capacity reduction and environmental policies again in the near future. In the meantime, prices will continue to fluctuate in accordance to policy changes.

Climate change and unstable supplies

Australia is one of the top producers of coking coal and iron ore in the world, and the biggest net exporter. Much of the world relies on the raw materials coming from Australian mines, but in 2016 and 2017, natural disasters shut down mines and paralyzed logistics routes in the country.

In September 2016, Australia experienced record-breaking heavy rainfalls that led to the collapse of the Anglo American and South32 mines, and derailed railways leading to Port Abbot Point. Heavy rainfall again shut down rail operations and other major logistics routes in the beginning of 2017.

El Niño and La Niña events around the world are causing sporadic weather patterns that are costly to the environment and economy. (Source: Time)

Such inclement weather can be attributed to increasingly frequent El Niño and La Niña events around the world. According to the U.S. National Ocean Service, “El Niño and La Niña are opposite phases of what is known as the El Niño-Southern Oscillation (ENSO) cycle,….the fluctuations in temperature between the ocean and atmosphere in the east-central Equatorial Pacific… La Niña is the cold phase of ENSO and El Niño as the warm phase of ENSO.” Such deviations from average temperatures can cause fluctuations in global weather and climate, posing high risks for coal supplies and logistics.

The Oligopoly of major suppliers

Already, the biggest coal and iron ore producing companies are concentrated in Australia and Brazil. The “big four” are considered to be Vale, Rio Tinto, BHP Billiton and FMG, whose combined exports amounted to 959 million tons in 2014, 1.068 billion tons in 2016 and is expected to reach 1.135 billion tons in 2018.

Their growing share of the global minerals export market as oligopolies over the last few years have only strengthened their power to negotiate prices and contributed to the abnormal amplification of iron ore and coking coal prices. Plus, their position only looks to be solidified with the rise of renewable energy and environmental policies that are forcing smaller mines to close down.

BHP Billiton is the biggest exporter of coking coal in the world, and it announced in 2016 that it would increase coal output by 8 percent over the next 3 years. The company already owns several major coking coal mines all over the world, but continues to acquire profitable mines with high-quality minerals. Other major mining companies are also expected to continue increasing their share of the market, shutting out smaller companies and increasing prices for coking coal and iron ore.

In the near future, coking coal and iron ore prices will continue to be volatile, forcing steel and related industries to adopt more efficient and sustainable production processes to compensate. As such, global steel companies like POSCO are investing in sustainable energy alternatives to power production, smart factories to enhance efficiency as well as researching high-quality steel materials to boost its competitiveness in the global market. Preemptive planning in an unpredictable market has led to POSCO’s growth and success over the last 50 years, and it will continue to be a global steel leader and solution provider for its partners.

The U.S. is headed towards a major shortage of truck drivers. (Source: The New York Times)

However, the U.S. is short of about 30,000 to 35,000 drivers for every 750,000 trucks, and the number of driver shortages may reach up to 245,000 by 2022. That’s because right now, the average age of truck drivers in the U.S. is 55, and potential new recruits are choosing to sign up for construction or manufacturing jobs instead.

All this leads to climbing prices for freight transportation. Last December, at the peak of holiday deliveries, U.S. companies saw the highest monthly average rate for freight transportation since 2010. The high operation costs and lower profit margins are putting a heavy strain on industries. Heading into 2018, companies have to compete for carriers as there is just one truck available for every 12 loads.

As a result, Major automakers are heavily invested in autonomous electric freight trucks such as Tesla, Volvo and Daimler, and there are many proponents of an eco-friendly, safe and driverless future for freight transportation. However, autonomous freight trucks are not a realistic option for companies just yet. At a time of transition between the old and the new, there is a serious lack of capacity in freight transportation, and companies are left to deal with the higher costs for delivery.  

But good news right around the corner

Although the driver shortage is a major concern, it is a natural phenomenon in the transition towards a safer, more sustainable and more efficient freight transportation industry.

Already, Uber has its autonomous trucks on the highways of Arizona. Every truck does have a human driver present to take over anytime, and the company uses transfer hubs to transfer goods between highways and local roads. Autonomous trucks are the safest and most efficient for use on highways, so human drivers transport goods from highways to the final destination. The company is working to operate without human backup drivers in the near future.

Embark also has its autonomous trucks in operation. Earlier this year, the company made a successful 2,400-mile trip from California to Florida with a human safety driver on board. The company has plans to commercialize its services in the coming years.

Speeding up delivery

Numerous other automotive and tech companies besides those mentioned above are getting ready for autonomous freight transportation. The faster autonomous freight trucks are able to operate commercially, the faster industries can cut costs, improve delivery times and reduce their carbon footprint.

This means software technology, high-capacity batteries as well as the right automotive materials will play a crucial role in the future of the freight transportation industry, as well as in related industries. This transformation will open up new business opportunities for automakers, software companies as well as steel manufacturers like POSCO.

For autonomous truck manufacturers looking for ultra-lightweight yet super strong materials for optimal fuel efficiency, POSCO developed POSCO GIGA STEEL. The advanced high-strength steel (AHSS) material is 3 times stronger and 3.5 times cheaper than aluminum. Steel is also 100 percent recyclable and an electric vehicle made of AHSS requires 30 percent less energy than aluminum throughout its entire lifecycle. POSCO also developed a premium non-oriented electrical steel called Hyper NO for the most advanced and sustainable electric motors.

POSCO also works with its auto partners to research and provide customized technology and materials solutions for their autonomous EVs. In the midst of a critical shortage of truck drivers, POSCO hopes to speed up autonomous EV adoption both for personal and commercial transportation and aid the transition into a more efficient and environmentally sustainable economy.

The 2018 North American International Auto Show brought the biggest names in the auto industry together for a show and tell. (Source: News Atlas)

Continuing on what we saw during the past few years, the focus this year again was on improving safety, performance and design, all at the lightest weight possible for fuel economy. While there have been debates in the past about the best lightweight material, there was a clear winner at this year’s NAIAS. Almost every car, including the 2018 Car of the Year, was clad in advanced high-strength steel (AHHS) and significantly lighter than their predecessors.

Take a look at some of this year’s steel-clad cars.

SEE ALSO: 5 Reasons Why AHSS Tops the Market for Lightweight Auto Materials

2018 Car of the Year: Honda Accord

The 2018 Honda Accord took home the prestigious title of Car of the Year due to its lightweight and improved strength and performance. The 2018 model contains 29 percent ultra-high-strength steel (UHSS) in its chassis and 54.2 percent high strength steel (HSS). With these applications, the Honda Accord achieved a weight reduction of 110 to 176 pounds while improving its body torsional rigidity by 32 percent and its bending rigidity by 24 percent.

2019 Chevy Silverado

The all-new Chevy Silverado comes armed with plenty of steel. One of the features that contribute to its improved safety is the bed floor made of roll-formed HSS. Also, 80 percent of its fully-boxed steel frame is made of HSS and AHSS forms the Silverado’s safety cage. Overall, the new model is taller and 7 inches wider than before. Nevertheless, the all-new Silverado is 450 pounds lighter with a 10 percent increase in torsional rigidity than the previous model.

2019 Dodge Ram 1500

The 2019 Dodge Ram 1500 is another steel-intensive vehicle revealed at NAIAS. About 98 percent of this year’s model is made from HSS, and is the lightest, longest and most efficient frame in the half-ton truck segment. The wheelbase and crew cab is 4 inches longer than the previous model. The Dodge Ram 1500 also has several new safety features. The unique front-splayed frame rail technology, frame-mounted HSS tire blockers and fully-boxed side rails allow the car to absorb more energy in case of impact and minimize structural damage.

2019 Kia Forte

The 2019 Kia Forte is taller, wider and longer than before with 54 percent of its chassis made of AHSS. It also has a 16 percent stiffer body-in-white and the new seat frames are lighter yet stronger as Kia has its eyes on top ratings from the Insurance Institute for Highway Safety (IIHS) for the second consecutive year. The lighter and stronger vehicle will consume about 9 to 20 percent less fuel as well as drop noise levels by 5 decibels.

Why the Steel Overload?

As mentioned above, the latest cars are steel-intensive and automakers increasing the amount of HSS, UHSS and AHSS in their mix of materials. Of course, the main reason for this is steel’s innate properties that make it the ideal solution for automakers looking to cut back on weight and still satisfy safety standards. However, automakers also learned a good lesson from automakers who chose another popular lightweight material – aluminum.

SEE ALSO: Materials Matter: Why Steel Beats Aluminum in the Sustainability Debate

Back in 2014, Ford released its F-150 with an all-aluminum body. The move was bold and the cars sold fast as it was a whole 700 pounds lighter than previous models. Consumers got to drive away with a drastically improved fuel economy, but it didn’t take long for them to realize the big, expensive problem with aluminum bodies: repairs.

Although steel and aluminum are similar in terms of its lightweight properties, aluminum reacts differently than steel under heat. Aluminum does not have metal memory, while steel does, making it hard to reshape and repair following an accident. Welding aluminum also takes much more skill and precision than steel, and there are few repair shops that are equipped to handle aluminum. As a result, drivers not only have a hard time finding repair shops for their aluminum cars, they have to pay a hefty price for repairs compared to repairs for steel cars. For example, Jalopnik reported one of the first cases of the F-150 repairs back in 2015 cost USD 17,000 and a month-long repair time.

Of course, this was a rare case highlighting the steep learning curve of repairing aluminum vehicles, but it also highlights the fact that steel is still the norm when it comes to automotive materials, and judging from the 2018 NAIAS, it’s going to stay that way for quite some time.

Scientists predict 2018 may be a tumultuous year for earthquakes. (Source: Take Two)

As structural damage is the leading cause of injury and deaths during an earthquake, architects, engineers and builders need to make sure buildings are built with the right materials and design.  

SEE ALSO: What it Takes to Build a Natural-Disaster-Proof House

The Materials

The most dangerous type of earthquakes are ones that trigger horizontal movements, because tall buildings are better at resisting vertical loads than horizontal ones. These ground motions can damage building foundations in a matter of minutes, causing severe injuries and deaths. Building a structure to withstand seismic waves starts with the right materials with the right properties, and steel is by far the most widely used material for building earthquake-resistant buildings.

According to the World Steel Association, ductile buildings are safer as they dissipate energy from seismic waves. A building will typically have ductile parts that can undergo plastic deformations without complete structural failure during an earthquake. Steel is the most common type of material for such parts.

Moreover, due to the law of inertia, the lighter the building, the less force seismic waves will exert on the building. That’s why it’s important, especially for taller buildings, to be made of light and flexible materials such as steel that can “bend” with the movement of earthquakes. On average, multi-story steel buildings are 60 to 70 percent lighter and 10 times stronger than concrete-framed buildings of the same size.

The Design

With steel, builders can add vital designs and reinforcements to keep the structure standing through an earthquake. Here’s some of the most widely-used measures.

Cross braces transfer the force of an earthquake to the ground. (Source: Earthquakes in India)

The structural integrity of buildings can be reinforced with steel cross braces that frame the exterior of a building in an x-shape. Ultimately cross braces can transfer the force of seismic waves back down to the ground, instead of letting the building take the hit. Builders can also reinforce the walls of buildings with additional vertical walls, or shear walls, that add stiffness to the frame of the building, allowing it to resist swaying or horizontal movements.

Base isolators absorb much of the shock of seismic waves. (Source: Embelton)

Base isolation involves separating the building from the foundation so that the isolators to absorb shock from the earthquake. The isolators allow the building to move at a slower pace because they dissolve a large part of the shock. Moment-resisting frames also effectively dissipate energy from floors and roofs to the building’s foundation and the stiff yet flexible frames can change shape during an earthquake. Although more costly, moment-resisting frames enable buildings to withstand an earthquake with excessive horizontal movement.

Putting it into practice with POSCO’s Steel House

In September 2017, Young Bae Kim’s home in Gyeongju province, Korea was hit with a 5.8 magnitude earthquake, just 8.9 km from where the earthquake started. Surprisingly, Kim’s home was unscathed. “I could feel the ground shake, but the house was completely under control.” Kim expressed.

Kim lives in one of the Steel Houses built by POSCO employees who volunteer to build homes and bridges for communities in need. Each Steel House is made with POSCO’s lightweight structural steel known for its durability, fire resistance and vibration resistance. The homes also incorporate PosMAC, a specialized galvanized steel that is 5 to 10 times more corrosion-resistant than standard steel and is more durable and affordable.

POSCO Employees volunteer their time to build steel houses in rural communities.

Because all the Steel Houses survived the Gyeongju earthquake while other homes were damaged, more and more people in Korea are choosing steel for their homes over traditional building materials such as wood and concrete. The same trend can be observed in Japan, where earthquakes are much more frequent. In order to build more earthquake-resistant buildings, steel is still the best solution available.

However, these building projects are on another level of huge, and with all the megacities popping up throughout the country, China boasts many of the biggest infrastructure projects in the world. Here’s the Steel Wire’s look at some of the most impressive to date.

Three Gorges Dam

China is home to the largest dam in the world, measuring 1.5 miles in length and sitting 60 (!) stories tall. The Three Gorges Dam took 1.92 million tons of rolled steel to complete, along with 10.82 million tons of cement and 1.6 million cubic meters of timber. The dam opened in 2003 on the Yangtze River and last year, generated a record-high 97.8 billion kilowatt-hours of electricity, 4.35 percent higher than the previous year.

Beijing Capital International Airport

Beijing Capital International Airport (PEK) was the second largest and busiest airport in the world in 2016, just behind the Hartsfield–Jackson Atlanta International Airport in the U.S. PEK recorded 94,393,454 passengers that flew in and out in 2016, a 5 percent increase from 2015, and is easily the biggest airport in all of Asia.

The first phase of the airport cost USD 3.5 billion and was completed in 2008, but in order to handle the growing number of passengers, an expansion project is planned for 2025. The estimated 5-year project will almost double PEK’s capacity and cost an additional USD 13 billion.   

Jiaozhou Bay Bridge

China is also home to the longest sea-crossing bridge in the world. The massive structure stretches over 26.4 miles and connects the cities of Qingdao and Huangdao. The 110ft width accommodates 6 traffic lanes that are supported by 5200 steel pillars.

The bridge first opened in 2011 and took USD 2.3 billion and over 10,000 workers to build. The Jiaozhou Bay Bridge also took 450,000 tons of steel to complete, allowing the bridge to be able to withstand earthquakes up to 8.0 in magnitude, typhoons and the force from a 300,000-ton object.  

Jiuquan Wind Power Base

Not surprisingly, the largest wind farm in the world located in China. Jiuquan Wind Power Base is made up of 7,000 turbines that generate enough electricity to sustain a small country. The plant was approved in 2008, and the government has pledged an additional USD 17.4 billion by 2020 as part of the effort to develop China’s renewable energy industry. For now, only 3.3 percent of all the electricity generated in China comes from wind turbines. With the additional investment, Jiuquan Wind Power Base will be able to generate a massive 20 gigawatts of sustainable electricity.

New Century Global Center

What does the biggest building in the world look like? A mini country. Located in Chengdu, Sichuan province, the New Century Global Center combines a shopping mall, water park, hotels, movie theaters, offices, restaurants, ice rink and more into 19 million sq.ft. of space. The structure is made of glass and steel and measures 500 meters long, 400 meters wide and 100 meters high. Designed by architect Zaha Hadid, it even has artificial sun for the perfect weather, 24 hours a day.

Port of Shanghai

The world’s biggest ports are mostly located in China, and the biggest one is the Port of Shanghai. In 2012, 744 million tonnes of cargo and 32.5 million twenty-foot equivalent units (TEUs) of steel containers passed through the port. The entire area of the port on the Yangtze River covers 3,619km² comprised of 3 main ports: Wusongkou, Waigaoqiao and Yangshan Deep-Water Port. About 25 percent of China’s trade passes through the Port of Shanghai, or 2,000 steel container ships per month.

Most recently, the 4th phase of the Yangshan Deep-Water Port was completed, making it the largest automated port in the world. It spans across 2.23 million square meters, and can automatically handle 4 million standard containers per year, or 25 per hour. It was also built to accommodate the heaviest ships in the world.

China is using its steel to build up the country’s infrastructure, and set world records along the way. Besides being impressive in size, the structures are expected to contribute to greater connectivity and economic prosperity throughout China.

CEO Kwon explores CES 2018

As such, CEO Kwon made his first official visit to the 2018 Consumer Electronics Show (CES) in Las Vegas earlier this month to stay on top of the latest trends in connectivity and smart solutions that can be applied to the manufacturing process in smart factories.

SEE ALSO: POSCO CEO Ohjoon Kwon Visits CES 2018

Ultimately, a smart factory for POSCO would entail using smart sensors to pick up data, smart analysis through AI and automated production processes. Moreover, the smart factory would store and analyze its big data and apply it to make future improvements and prevent malfunctions. Aligned with many of POSCO’s business growth engines, major topics and themes at CES 2018 included smart homes, smart cities, autonomous cars and AI, and more than 3,900 companies put forth their best innovations.

Smart Connectivity

As more and more cities undergo smart transformations, the next big trend will be data collection and analysis through 5G connectivity. It was no surprise to see numerous innovations in smart transportation, smart grid, public safety, healthcare, data analytics and more at CES 2018. Moreover, city officials from early-adapting cities such as Kansas City, Miami and Las Vegas took to the stage to discuss their cities’ smartization plans. Some of the topics discussed included using GIS mapping software, smart construction, inclusive technology and autonomous transportation to enhance citizens’ productivity, efficiency, safety and well-being.

CES 2018 was a platform for smart city discussion. (Source: Bosch)

CEO Kwon visited related booths to learn about new technologies POSCO could apply to its businesses. Currently, POSCO’s smart factories are run by POSCO ICT’s smart platform called PosFrame, which allows the factory to apply a digital genome map to operations via data collection, instantly convert smart factory initiatives in domains, act as a common platform for new technologies and apply the same, standardize smart factory model to other facilities through reusable software.

Also at this year’s CES, POSCO ICT signed an MOU with DPR Construction, a leading smart construction company to apply PosFrame to construction sites for more efficient, cost-effective and smarter construction processes.

Smart Transportation

Another major theme at this year’s CES was mobility. Namely, autonomous and electric mobility. Companies from all across the board from traditional car manufacturers and software companies to gaming companies lined up to showcase their new innovations.

Even as the market for sustainable EVs and autonomous EVs look to expand in 2018 and beyond, EVs only make up about 1 percent of the global fleet of cars and there’s still a ways to go before EVs become the norm. Drivers need to feel safe in their EVs or autonomous EVs, want greater range on a single charge and need to see more charging infrastructure in their communities before making the switch.

What’s more is that just because a vehicle runs on electric batteries, it doesn’t automatically mean the vehicle is eco-friendly or transmits less harmful emissions. Manufacturers and consumers alike have to take a lifecycle approach to assess the car’s impact on the environment from production to end of life recycling.

POSCO works with numerous partners to develop leading solutions for electric vehicles.

That’s why POSCO is working with automakers to come up with vital solutions in the auto industry for a greener future. It supplies partners with an advanced high-strength steel (AHSS) called POSCO GIGA STEEL that is both lightweight and super strong, allowing cars to travel with less energy without compromising passenger safety.

POSCO is also a lithium provider and has developed an innovative technology to speed up the extraction process, saving time, costs and damage to the environment. It also works with car makers to apply premium electric steel to partners’ electric motors to increase efficiency and cut costs.

With so many exciting new innovations and technologies surrounding EVs, POSCO will undoubtedly play a significant role in ensuring automakers have the tools they need to realize a green future.  POSCO will work to stay ahead of newly emerging technologies to enhance the efficiency, sustainability and performance of all of its solutions.

For the International Broadcasting Center (IBC) completed last April, builders used POSCO’s Pos-H steel. Building parts were made by precisely cutting and welding the hot-rolled steel plates and thick plates. Pos-H is custom-made for structures and does not produce any waste unlike existing hot-rolled shape steel with fixed dimensions. In addition, POSCO’s dry fire-resistant cladding technique was applied to all the pillars of the IBC. The dry fire-resistant cladding technique eliminates the process of applying fire-resistant paint to pillars for fire prevention, and instead, fire-resistant materials are wrapped around the pillars.

The Media Residence that will house reporters during the PyeongChang Winter Olympics resembles a steel showroom due to its impressive design. PosMAC, which is over 5 times more corrosion-resistant than general galvanized steel sheets as it is coated with zinc, magnesium and aluminum, was specially printed to bring to life the fiber texture. PosMAC was used for the exterior of the bathrooms and walls for durability as well as artistic value. The surface steel plates plated with aluminum and zinc, called ALZASTA was treated to achieve a glittering spangle pattern texture and applied to the residence fire doors, valve enclosures and hallways. PossSD, stainless steel with a level of reflectivity equal to that of a mirror, was used inside the bathrooms.

The Media Residence was completed on December 15, after 8 months of construction. All of the 300 rooms were prefabricated in a factory and assembled at the site. This is known as modular construction. It reduced the construction period by 18 months compared to building with general concrete. More than anything else, modular construction makes it possible to move the structure to another location and reuse it. In this respect, modular construction is regarded as the best choice for the facilities that will be removed after the Winter Olympics. The Media Residence will be reused as a hotel or dormitory.

Finally, the Kwandong Hockey Center’s exterior walls are made of 329LD POSCO stainless steel, which is highly corrosion-resistant and robust. POSCO provided the structural analysis by calculating the optimal thickness for the walls and reduced the thickness by 25 percent.  

After the PyeongChang Winter Olympics and Paralympics, POSCO will continue to provide construction solutions through is WPP and technologies for its partners.

With the performance increase in both steel and non-steel businesses in Korea and overseas, operating profit was highest it’s been in the last 6 years, and the operating profit to sales ratio was 7.6 percent. Year-on-year consolidated sales increased by 14.3 percent and operating profit and net profit increased by 62.5 percent and 183.7 percent respectively.

The total operating profit of POSCO’s non-steel businesses, which reached KRW 10 billion last year, also turned into a surplus. There was an overall increase in non-steel businesses including trade, energy, ICT, chemicals and materials, resulting in KRW 1.0927 trillion of profits, up KRW 1.0798 trillion from last year.

This is in line with POSCO CEO Ohjoon Kwon’s strategy to focus on group management by securing future growth engines and reforming non-steel businesses.

※ Total operating profit per sector

Indonesia-based integrated steel mill, PT. KRAKATAU POSCO, also generated a surplus for the first time since operations began in 2014. Mexico-based automotive steel sheet plant, POSCO Mexico, as well as India-based cold rolled steel corporation, POSCO Maharashtra, also achieved their highest operating profit, tripling the total operating profit of overseas steel business.

Moreover, separate sales and operating profit increased year-on-year by 17.4 percent and 10.1 percent respectively to KRW 28.5538 trillion and KRW 2.9025 trillion, and the net profit was KRW 2.5457 trillion.

Production and sales decreased year-on-year due to the repair and facility rationalization of Pohang Blast Furnace No. 3, but the sales ratio of World Premium products with better technology and higher returns increased to 53.4 percent, its higher ever.

Financial soundness was also saw improvements. POSCO’s Consolidated debt ratio decreased by 7.5%p year-on-year to 66.5 percent, the lowest since 2010. Separate debt ratio also decreased by 0.5%p year-on-year to 16.9 percent, constantly renewing the lowest record on a yearly basis.

POSCO also demonstrated a cumulative financial improvement of KRW 7 trillion with 150 cases of restructuring in the last 4 years, reinforcing the business structure as well as financial competency. Accordingly, this year the company expects to make more investments in new growth engines such as lithium and cathode materials as well as energy and construction in addition to renewing the facilities at its steel mills. Thus, there will be a budget of KRW 4.2 trillion for consolidated investment, an increase of KRW 1.6 trillion compared to last year. The consolidated sales target is KRW 61.9 trillion.

※ POSCO’s 2017 business performance

Since last February, CEO Kwon has visited Siemens, GE and other businesses in Silicon Valley to explore new technologies and expand POSCO Group’s smartization plan. At CES 2018, CEO Kwon saw first-hand the latest smart technologies and plans to implement them to all of POSCO’s core businesses including steel, construction, IT and energy. He also met officials from leading smart companies such as GE and DPR Construction, and examined possibilities for cooperation over commercializing POSCO’s smart solutions.

POSCO Kwon met Heilmann Matthias, President and CEO of Digital Solutions at Baker Hughes General Electric (BHGE). Matthias oversees the digital solution business of GE Group, and the two discussed the development of PosFrame, POSCO’s proprietary smart platform, its compatibility with Predix, GE’s smart platform, as well as the possibility for joint commercialization.

In particular, POSCO ICT is planning to sign an MOU with DPR Construction, the world leader in Smart Construction, to collaborate on smart projects and find opportunities to apply new ICT technologies to construction. Through this MOU, the two companies will cooperate on projects such as constructing and operating highly-efficient, low-cost data centers and smart factories controlled by PosFrame.

CEO Kwon also visited the automobiles, home appliances, smart city and smart home exhibition booths. He examined the latest tech trends of IT utilization in steel-consuming industries to develop compatible materials and steel solutions.

He also made sure to explore electric vehicle (EV) batteries and new IT technologies surrounding EVs, as lithium materials are the new growth engine of the company. CEO Kwon also evaluated the possibility of securing new markets for the group’s construction business at home and abroad.
