中国白酒产业未来绿色“酿造”

Core Viewpoint - The article highlights the commitment of Wuliangye, a leading Chinese liquor company, to green development through the establishment of a new wastewater treatment plant and ecological wetland, aligning with China's environmental goals and sustainable practices [2][4]. Group 1: Wastewater Treatment Plant - Wuliangye has recently launched a new wastewater treatment plant within its industrial park, utilizing an AI-driven smart water management system for automated and precise control of the treatment process [2]. - The plant, with an investment of approximately 1 billion yuan, has a daily wastewater treatment capacity of 23,000 cubic meters and can generate over 50 million kilowatt-hours of electricity annually, reducing coal consumption by about 9,635 tons and greenhouse gas emissions by approximately 30,000 tons each year [2]. - The electricity generated not only meets the plant's own needs but also allows for excess power to be fed into the grid [2]. Group 2: Ecological Wetland - Adjacent to the wastewater treatment facility, Wuliangye has developed a 23,000 square meter ecological wetland, which helps reduce chemical oxygen demand (COD) by approximately 420 tons and total phosphorus by about 4 tons annually, while providing over 4 million cubic meters of water replenishment to the nearby Songgong River [4]. - The wetland employs natural filtration methods using quartz sand, volcanic rock, and aquatic plants to further purify treated wastewater before its final discharge or use for ecological replenishment [2]. Group 3: Broader Industry Context - The Chinese liquor industry, including Wuliangye, is increasingly focusing on reducing reliance on fossil fuels and enhancing sustainability through initiatives like "coal-to-gas" and "gas-to-electric" transitions, as well as biomass cogeneration projects to manage waste [4]. - The industry is responding to national goals for carbon peak by 2030 and carbon neutrality by 2060, with other companies like Shui Jing Fang also setting ambitious carbon reduction targets [4]. - Wuliangye emphasizes that a healthy ecosystem is essential for producing quality liquor, positioning green development as a necessary path forward for the industry [4].
