1291 green factories, 104 industrial parks, and 205 green supply chain management enterprises have become models of green transformation in industrial manufacturing. On November 8, the Ministry of Industry and Information Technology released the 2023 green manufacturing public list. Among them, Haier, Konka, Midea, Lenovo, Lisun Electronics and many other electronics and home appliances enterprises were selected. Industry experts told reporters that in recent years, China’s home appliances and consumer electronics companies are actively building a green manufacturing system, which is not only to pave the way for the export of products overseas, but also to break international green trade barriers and establish a high-end image of Chinese brands.

Unlock green benefits from the full life cycle

“Promoting green manufacturing is an important path and starting point for all industrial enterprises, including home appliance/consumer electronics enterprises, to achieve carbon neutrality.” Li Meng, a senior project officer for green supply chain at the Institute of Public and Environmental Affairs (IPE), told China Electronics News.

It is understood that green resources, green production and green products are the three main links of green manufacturing system. Green resources refer to the use of green materials and energy in the manufacturing process; Green production includes green design and green production technology; Green products refer to those products that have relatively little damage and impact on the environment during the whole process of production, use and disposal after use.

“Promoting energy conservation and emission reduction through green manufacturing and minimizing the environmental impact of the whole life cycle of products has always been the goal pursued by home appliance companies and consumer electronics companies.” Zhao Yue, director of energy conservation and green energy Research office of CCID Research Institute, said in an interview with China Electronics News.

In recent years, home appliance and consumer electronics enterprises have actively practiced green manufacturing, and built a green manufacturing system with green products, green supply chain, and green factories as the core, to tap the potential of energy saving and carbon reduction from the whole life cycle, and release green benefits.

“In the fiscal year 2022, through the use of clean energy and the adjustment of energy structure, the cumulative carbon reduction reached 8,988 tons, and the proportion of clean energy reached 10% of the total electricity consumption of the park.” In an interview with “China Electronics News”, the relevant person in charge of Lianbao Technology said that the company’s energy-saving lighting transformation – the transformation of semiconductor light-emitting chips instead of filament, the entire park and workshop to achieve 30,000 energy-saving lamps transformation, saving about 2.5 million kWh of electricity per year, reducing carbon volume 1445 tons/year.

In addition, by reducing the indirect emissions generated by purchased power, the company has chosen to adopt energy-saving or renewable energy management measures, which directly reduce the carbon footprint of the park and promote environmental sustainability. Among them, the photovoltaic project adopts the “block power generation, centralized grid connection” way of high voltage grid, as of July 2023, the third phase of the photovoltaic power station after the park PV installed a total of 10.12MW, is expected to generate 9.5 million KWH of electricity per year, the annual renewable energy generated accounts for about 12% of the company’s total annual electricity consumption, equivalent to planting 690,000 trees. Carbon reduction of 5519 tons/year.

The relevant person in charge of the United States said in an interview with the reporter of China Electronics News that the United States washing machine factory attaches importance to energy-saving technology upgrading and comprehensive utilization of resources, and its photovoltaic power generation capacity of 4.83MW in the first phase of the factory, the annual electricity generation capacity reached 4.1 million degrees, and the proportion of green electricity accounted for more than 5%; At present, the factory has completed the second phase of photovoltaic construction, and the new photovoltaic power generation capacity is 18MW, the annual increase of electricity generation is 20 million KWH, the proportion of green electricity in the factory is increased to more than 30%, and the annual carbon dioxide emissions are reduced by 19,000 tons.

Haier Zhijia is committed to the research and development of cutting-edge green energy-saving technology and applied in its products. For example, its refrigerator products are equipped with F-D PLUS frequency conversion technology, which saves 15% energy than traditional refrigerators; The washing machine with the new essence washing function saves 38% of water compared with the traditional drum washing machine; The water heater applies the environmental factor frequency conversion control strategy, and the energy efficiency can be increased by 15.5%; The air conditioner uses the variable shunt technology of the heat exchanger, and the annual power consumption of a single unit can be reduced by 389 degrees; Magnetic levitation central air conditioning application of zero-friction oil-free operation technology, energy saving 50%, since the birth of the cumulative carbon reduction of 2.166 million tons.
