In the East China Sea Chemical Base, for instance, visiting a garden-style enterprise reveals a striking contrast to traditional industrial sites. Here, there are no towering chimneys emitting smoke, and the sky remains clear with blue skies and white clouds. All the green water comes from a sophisticated wastewater recycling system, which saves over 250,000 tons of water annually, significantly reducing energy consumption and emissions.
This is just one example of the company's broader efforts in energy conservation and emission reduction. According to the person in charge at China National Chemicals, the company has made remarkable progress not only in water conservation but also in wastewater treatment and COâ‚‚ reduction. The company has integrated energy efficiency and environmental protection into its development plan, setting clear targets and ensuring that each department signs a responsibility agreement to meet these goals.
One of the most effective ways for a chemical plant to save energy and reduce emissions is by maintaining long-term stable operations. This minimizes overall energy use and reduces waste generation. To achieve this, China National Chemicals has focused on improving staff operational skills through structured training programs. As a result, the 600,000-ton methanol plant recently achieved a 150-day continuous operation record, while the Fudao-II plant completed its second 100-day cycle last year.
Last year, CNOOC invested nearly 30 million yuan to construct an 8,000 cubic meter emergency sewage pool, significantly enhancing its ability to handle unexpected wastewater and ensuring zero pollution in discharge. With low daily emissions, the sewage treatment system operates at full capacity, further supporting the company’s environmental goals.
The Eastern 1-1 gas field, one of China’s largest identified and developed gas reserves, produces natural gas with high carbon dioxide content. To address this, the company has invested in environmental projects. In 2006, they launched a food-grade carbon dioxide project with an annual output of 30,000 tons, capable of recycling 24 million standard cubic meters of exhaust gas yearly. Additionally, a project to produce biodegradable plastics from CO₂ began last year, aiming to commercialize this technology and promote large-scale CO₂ utilization. This project is expected to be fully operational by June 2008.
CNOOC has also focused on small energy-saving opportunities, such as minimizing unnecessary lighting in the plant area, adjusting lighting schedules based on daylight changes during summer, and maintaining air conditioning temperatures at 26°C or higher. Office spaces make full use of natural light throughout the day, contributing to overall energy efficiency.
Yang Yexin, CEO of China Shipping Chemical Co., Ltd., emphasized that while developing industries is crucial for economic growth, it should never come at the cost of resource depletion or environmental harm. He stated that the company would rather avoid development if it leads to such negative outcomes.
China Shipping Chemicals is a key player in the Dongfang Chemical City, operating three major plants at its Hainan base: a 520,000-ton urea plant, an 800,000-ton urea plant, and a 60-million-ton methanol facility. These operations reflect the company’s commitment to sustainable and environmentally responsible industrial practices.
