NUREMBERG, Germany–The Chinese Research Academy of Environmental Sciences (CRAES) achieved remarkable success at the 77th Nuremberg International Invention Exhibition (iENA), held from November 1 to 3, 2025. Showcasing its innovative prowess, the academy was honored with one Gold, one Silver, and five Bronze medals for its cutting-edge environmental technologies.

　　Often hailed as the "Oscars of Inventions," iENA is one of the world's oldest and most influential invention fairs. This year's event at the Nuremberg Exhibition Center featured 540 inventions from 21 countries. The international jury awarded CRAES's technologies with a total of seven medals, a testament to their quality and impact, especially considering that only about 10% and 20% of the entries received Gold and Silver medals, respectively.

　　The CRAES delegation presented a suite of patented technologies that offer innovative solutions to pressing global environmental challenges:

　　Gold Medal: Muti-Objective Optimization Method for Groundwater Pollution Monitoring Network by the team of Institute of Soil and Groundwater Environment.

　　Silver Medal: Integrated Prediction and Early Warning System for Algal Blooms by the team of National Joint Research Center for Ecological Protection and High-Quality Development of the Yellow River Basin.

　　Bronze Medals: Awarded to five technologies, including the AIR Type High-Efficiency Ozone Catalyst for Industrial Wastewater Treatment, Multi-Core Sensor System, and Isolation and Recovery Method Therefor, Water Environmental DNA Collection Apparatus, Anaerobic Aerobic Integrated Treatment System for Perishable Organic Solid Waste, and Multi-Source Organic Solid Waste Pyrolysis and Oil-Gas Targeted Reforming System.
