变“废”为宝！海洋垃圾制衣、“污水”冲咖啡

Group 1 - The concept of circular economy is increasingly demonstrating its benefits across the country, with various new technologies enabling the transformation of waste into valuable resources [1] - In Fujian, used plastic packaging films are being processed into high-quality eco-friendly films that have passed national food-grade certification, breaking barriers in the recycling of food-grade materials [2] - Carbon dioxide, previously seen as an industrial emission burden, is now being utilized as a resource for green development, with over 74,600 tons injected into oil wells in Daqing, leading to an oil production increase of 19,400 tons this year [2] Group 2 - A new urban wastewater resource concept plant in Jiangsu is revolutionizing wastewater treatment by employing a "triple-loop" system that transforms wastewater into drinkable water, achieving a removal rate of over 99% for emerging pollutants [3][4] - The concept plant produces 5,000 cubic meters of biogas daily from mixed fermentation of sludge and other organic waste, generating 12,000 kWh of electricity per day, achieving 100% energy self-sufficiency [4] - The plant reduces carbon dioxide emissions by approximately 7,000 tons annually and decreases fertilizer usage by 20% through the use of nutrient-rich soil made from biogas residue [4] Group 3 - Circular economy is a core initiative in China's "carbon peak" actions, providing critical support for green and low-carbon transformation, with significant contributions to carbon reduction during the 14th Five-Year Plan period [5] - The recycling system for waste materials in China is continuously improving, with a 94% reuse rate of industrial water in 2023, surpassing national targets, and total recycled resources exceeding 400 million tons [5] - The value of the resource recycling industry in China has grown from approximately 2 trillion yuan in 2015 to 4 trillion yuan in 2023, with expectations to exceed 5 trillion yuan by 2025, indicating a trend towards digitalization, collaboration, and internationalization [5]
