On August 15, during the 2025 Vibrant China Research Tour, the company's General Manager, Liu Zichao, presented the delegation with the company's specific measures in environmental protection and green manufacturing.

BOE is a global leader in semiconductor display production. Its production base in Chongqing Liangjiang New Area is the core facility for the company’s laptop display screens.

The displays produced by Chongqing BOE account for 70% to 80% of the total output of BOE’s laptop screens. Globally, the company holds a market share of approximately 25% to 26%. Roughly one in every four laptop displays on the market comes from Chongqing BOE.

Liu stated that Chongqing BOE has implemented multiple effective measures in energy usage, production process optimization, and waste recycling, all of which aim to reduce carbon emissions and resource consumption.

Chongqing BOE has actively adopted photovoltaic (PV) technology to reduce its carbon footprint and promote green energy. The company has installed a large number of PV power generation systems on the rooftops of its factories and external parking areas, generating an annual output of 12 million kilowatt-hours, which is expected to reduce carbon dioxide emissions by 7,000 to 8,000 tons.

Chongqing BOE also promotes recycling wastewater, waste gas, and solid waste during its production process. The company has built extensive renewable water facilities within the factory, utilizing approximately 40,000 to 45,000 tons of water daily, with 80% of this water sourced from its recycling system.

This reduces dependence on external water resources. Additionally, Chongqing BOE has effectively controlled waste gas emissions during production, particularly harmful gases such as fluorine-containing gases, by implementing stringent environmental protection measures.

To achieve a green production loop, Chongqing BOE has closely collaborated with its upstream and downstream industrial chains, establishing a complete sustainable development cycle from raw material production and product manufacturing to recycling and reuse at the end of the product’s life cycle.

The company, together with strategic partners such as Lenovo, has developed a "zero-carbon" product, which, according to Liu, achieves "zero carbon emissions" during its production process.

During the presentation of Chongqing BOE's innovative products, Liu showcased the Huawei foldable smartphone and noted that Chongqing BOE is a supplier for this model. In addition to special products like the flexible screens used in foldable phones, Chongqing BOE also produces conventional smartphone screens for brands such as OPPO, Vivo, and Xiaomi.

CHONGQING'S INNOVATIVE WASTE MANAGEMENT INDUSTRY

Chongqing’s waste management industry is also innovating, particularly in waste-to-energy generation, demonstrating the potential for sustainable development.

On the same day, the delegation visited the Chongqing Sanfeng Yulin Environmental Power Generation Co., Ltd. in Yubei, which operates a waste incineration power plant.

“Our facility primarily handles household waste, processing about 3,500 tons per day,” said Li Xutian, the Technical Equipment Department Director of Chongqing Sanfeng Yulin Environmental Power Generation Co., Ltd.

According to the introduction, the waste is first transported to the incineration plant by closed-loop garbage trucks. After weighing, the waste enters the main plant's unloading hall. It is then stored in waste storage pits for three to five days, where the pile undergoes natural fermentation to reduce moisture content, increasing its calorific value and making it more suitable for incineration.

Next, the waste is sent to an incineration furnace with temperatures exceeding 850°C. The heat generated turns water in the boiler into steam, which drives a turbine generator to produce electricity, which is fed into the national grid.

The ash residue from the incineration process is repurposed as construction material, while the fly ash is treated with solidification for sanitary landfill disposal.

The smoke generated from the incineration process is purified, reducing particulate matter to 1 milligram per cubic meter and nitrogen oxides to 20 milligrams per cubic meter. The EU’s 2010 standards allow for 200 milligrams per cubic meter of nitrogen oxides and 10 milligrams per cubic meter of particulate matter, meaning the emissions from this plant are only one-tenth of the EU’s regulatory standards, according to Li.
