Workers Daily-China Industry Network reporter Che Hui

On November 6, Lenovo Group’s Innovation Industrial Park (Tianjin) was fully completed. The industrial park is located in the Tianjin Port Free Trade Zone Airport Economic Zone, covering an area of ​​112,000 square meters, with a total investment of over 1.8 billion yuan. It will create employment for more than 1,000 people in the Beijing-Tianjin-Hebei region and will produce 3 million computers and intelligent equipment annually in the future.

With “green zero-carbon, intelligent manufacturing” as its core positioning, the industrial park integrates production and manufacturing, R&D experiments, and digital display to create a highly automated, comprehensively intelligent, and replicable zero-carbon intelligent manufacturing solution for the industry.

On the morning of the same day, Lian Maojun, member of the Standing Committee of the Tianjin Municipal Party Committee and Secretary of the Binhai New Area Party Committee, Zhu Peng, Vice Mayor of Tianjin, Yang Yuanqing, Chairman and CEO of Lenovo Group, Liu Jun, Executive Vice President of Lenovo Group and President of China, witnessed the complete completion of the industrial park. .

“The comprehensive completion of the park is a milestone in the cooperation between Lenovo and Tianjin,” said Yin Xiaofeng, Secretary of the Party Committee and Director of the Management Committee of the Tianjin Port Free Trade Zone. The Free Trade Zone will use this as a starting point to focus on the development of strategic emerging industries together with Lenovo Group.

Guan Wei, senior vice president and head of global supply chain of Lenovo Group, said that Tianjin Innovation Industrial Park uses many advanced intelligent and green technologies such as the Internet of Things, 5G, edge computing, digital twins, and AI, and integrates nearly a thousand Lenovo patents to demonstrate It represents the highest level of zero-carbon intelligent manufacturing for Lenovo Group and even the ICT industry, and is the “summary” of Lenovo’s more than 30 years of self-owned manufacturing exploration.

New ecology builds a zero-carbon factory model from scratch

How to build an “ecological grade” zero-carbon factory from scratch?

Lenovo Group took two years to give the answer: the industrial park has implemented a “combination punch” of 90 carbon reduction measures in nine major areas, including green energy, architectural design, intelligent manufacturing, park management, and digital collaboration, which runs through the park’s design, planning, and construction. to the entire operation process.

The main carbon emissions of the manufacturing base come from energy consumption, while the industrial park uses renewable energy to the greatest extent. The 30,000 square meters of distributed photovoltaic panels laid on the roofs of three production buildings have a total annual power generation capacity of more than 5 million kilowatt-hours, equivalent to the annual consumption of 2,000 ordinary households. This move has reduced the park’s carbon footprint by 3,000 tons. Off-grid photovoltaic products are commonly used in the park, such as photovoltaic seats and sensor trash cans, as well as wind-solar hybrid street lights that are also powered by wind energy.

Unlike many factories that consider carbon reduction only after they are built, industrial parks focus on low-carbon and zero-carbon from the planning and architectural design stages. For example, the centralized design of the power room is adopted to reduce the energy supply radius from the national standard of 500 meters to less than 200 meters, reducing energy loss and material waste; the park introduces rainwater storage and gray water systems, saving more than 25,000 fresh water annually tons; using geothermal heat energy to adjust the temperature of the fresh air system through a heat exchanger, achieving 50% energy saving compared to heating and cooling methods. In addition, the park’s smart workshop buildings have obtained LEED gold certification, and only 6 out of 1,000 global manufacturing plants have received certification.

In smart parks, digital systems play a key role in reducing carbon emissions. Lenovo Group’s self-developed factory ESG solution ESG Navigator uses digital and information technology to achieve data visualization, traceability and compliance management, helping factories monitor energy use and thereby reduce energy consumption, reducing overall energy consumption by 5% to 10%. %. The zero-carbon 3D visualization platform uses technologies such as digital twins to analyze data collected by ESG Navigator in real time and match it with the park’s building and equipment models to help managers understand the park’s carbon emissions and help formulate more scientific policies. Carbon reduction strategies.

In operation, the park makes full use of every tiny opportunity to reduce carbon emissions and effectively recovers resources and energy. For example, the industrial park uses the heat emitted by air compressors to recover 1.12 million kilowatt hours of electricity every year, saving more than 800,000 yuan in electricity bills. In addition, the restaurant in the park has achieved 100% recycling of food waste and turned its resources into fertilizer, with a waste reduction rate of over 90%.

After comprehensive calculation, the annual carbon emissions of the park are about 12,000 tons. After determining the carbon emissions through digital means and adopting a set of carbon reduction combinations (including top-level design, self-carbon reduction, photovoltaic installation, and green power supply), it will be completed The factory is carbon neutral. Among them, self-emission reduction and green power and green energy account for more than 90%, reaching the industry-leading level.

Lenovo Group is one of the earliest technology companies in China to engage in low-carbon practices and fulfill social responsibilities. Before the completion of the Tianjin Industrial Park, Lenovo Group’s main domestic production bases have been selected as national green factories, green design products, green supply chain management practices, etc. It is also recognized by the Ministry of Industry and Information Technology.

New Intelligent Manufacturing, the culmination of more than 30 years of manufacturing exploration

Guan Wei said that the completion of the Innovation Industrial Park (Tianjin) not only reflects Lenovo’s accumulation of past explorations, but also establishes a new starting point for continuing to explore advanced manufacturing and assisting the high-quality development of the manufacturing industry. Lenovo Group has more than 30 years of manufacturing exploration and experience, and has manufacturing bases in Hefei, Wuhan, Shenzhen and other places. Among them, the Hefei Industrial Base has been awarded the “Lighthouse Factory” this year, and the Shenzhen Southern Manufacturing Base has been awarded the “Lighthouse Factory” by Lenovo Global. “Mother Factory”.

The Innovation Industrial Park (Tianjin) has been upgraded based on Lenovo’s smart manufacturing experience, and has finally achieved a high degree of automation and comprehensive intelligence, achieving “acceleration” of smart manufacturing in the entire process. A laptop comes off the assembly line every 9 seconds, with an annual output of more than 3 million units. The automation rate of the smart notebook production line reaches 60%, ranking first in the industry; the intelligent high-speed patch production line has an automation rate of 80%, of which the automation rate of patch segments is as high as 92%. %, the component placement speed can reach 172,000 per hour.

At the same time, some important links in production have been fully automated and unmanned, reaching industry-leading levels. In the notebook production line testing section, Lenovo Group’s independently developed fully automatic testing system can test more than 150 items in 8 categories within 2 hours, and the entire process is 100% black-light capable; in the packaging section, materials are automatically distributed and the process is unmanned. Production is agile and efficient.

The industrial park extensively applies automation and intelligent technologies, and uses and upgrades multiple digital systems self-developed by Lenovo Group, increasing overall production efficiency by 200% and reducing defective rates by 30%. Among them, Lenovo’s Manufacturing Execution System (LeMES) comprehensively tracks and manages the production process, improving production efficiency by 10%. The intelligent production scheduling system APS shortened the scheduling time from 2 hours to 10 minutes, increasing output by 19%. In addition, Lenovo’s intelligent process platform ESOP uses AI algorithms to generate optimal process arrangements and guide employees in real-time and dynamic operations.

In addition to the smart factory, the industrial park has built the industry’s highest level of zero-carbon black light smart three-dimensional warehouse. The warehouse has 28,000 cargo spaces, is 24 meters high, and looks like a “steel forest.” The warehouse applies 43 smart technologies such as 5G, digital twins, and visual recognition to save more than 70% of the warehouse space, reduce costs by 47%, improve material preparation and picking efficiency by 10 times, and pick accuracy as high as 99.99%. Smart warehouses can fully automatically transport materials to production lines and recover finished products, and operate normally under black light conditions. In addition to the visible production lines and warehousing, the park has also built a digital intelligent manufacturing “brain” – an intelligent manufacturing central control platform, which achieves comprehensive Intelligent management.

A new starting point to precipitate new productivity with zero-carbon smart manufacturing

As one of the three important power sources leading the country’s high-quality development, Beijing-Tianjin-Hebei has continued to strengthen collaborative innovation and industrial collaboration. Lenovo Group actively responded to the coordinated development of Beijing, Tianjin and Hebei and built an innovation industrial park in the “Three Golden Autumn” and two years span, fully demonstrating the speed of Tianjin and the speed of Lenovo. Guan Wei said that the industrial park is fully operational, further improving Lenovo Group’s all-round intelligent manufacturing layout in the “east, west, south, north, and middle” across the country, and further improving the resilience of the supply chain.

The completion of Tianjin Industrial Park has also created a highly automated, fully intelligent and replicable zero-carbon smart manufacturing solution for the industry.

During the construction of the Tianjin Industrial Park, Lenovo Group, as the initial unit, participated in the formulation of the first zero-carbon factory standard for the ICT industry. During the development process of the standard, pilot verification was also carried out in the Lenovo Group Innovation Industrial Park (Tianjin).

Based on the ESG Navigator digital system used in Tianjin Industrial Park, Lenovo Group launched LeGreen, an enterprise-level ESG solution, which integrates 8 functional modules and an ESG control tower to help enterprises develop zero-carbon development.

At present, the Tianjin zero-carbon factory case has been selected into the curriculum cases of Fudan University School of Economics and Management and Tianjin University School of Economics and Management. Lenovo Group will also publish relevant white papers on zero-carbon smart manufacturing factories, replicating the systematic zero-carbon experience of industrial parks from construction to operation to the world, and giving full play to the advantages of chain owners to jointly build a zero-carbon ecosystem with the upstream and downstream of the industrial chain.

Since 2017, Lenovo Group’s positioning of “one headquarters, two parks, and three centers” in Tianjin has gradually taken shape. It not only has another global headquarters office park besides Beijing, but also relies on the innovation industrial park and innovation technology park to create Advanced Innovation Industry Center, Intelligent Transformation Business Center and Northern Supply Chain Center.

The Tianjin Future Center is also built in the park, which houses the Lenovo 3S industry intelligent exhibition area, Lenovo intelligent manufacturing and global supply chain interactive experience space, etc.

In May this year, Lenovo Group signed a new strategic framework agreement with Tianjin City, which will focus on promoting the coordinated development of Beijing-Tianjin-Hebei in a deep and solid manner, high-quality development of manufacturing, revitalizing the city through science and education, strengthening the city with talents, supporting and leading the high-quality development of Binhai New Area, and promoting green and low-income industries. Deepen cooperation in eight aspects including carbon development, and contribute to the “Ten Actions” to help Tianjin comprehensively promote high-quality development and further promote the coordinated development of Beijing, Tianjin and Hebei. Currently, Lenovo Group is moving towards its third goal of “1,000 people and 10 billion” in Tianjin, that is, more than 3,000 employees, revenue of more than 30 billion yuan, and industrial output value of 10 billion yuan.

“The manufacturing industry must achieve green and zero-carbon transformation and forge sustainable development capabilities,” Yang Yuanqing said. In the future, Lenovo Group will continue to firmly promote the practice of digital-physical integration transformation and use technological innovation to drive the transformation and upgrading of China’s manufacturing industry towards digital intelligence and zero-carbonization. , injecting stronger momentum into the advanced manufacturing industry to accelerate the formation of new productive forces.
