What belongs in this category这个类别收什么
- BIR生物修复BioremediationThe use of biological agents, such as bacteria or plants, to remove or neutralize contaminants. This includes phytoremediation, constructed wetlands for wastewater treatment, biodegradation, etc.利用细菌、植物等生物媒介去除或中和污染物，包括植物修复、用于污水处理的人工湿地、生物降解等。
- ENG土地复垦Land ReclamationStudies that apply engineering principles and design techniques to restore land from wetlands, seas, lakes, deserts or mines, through drainage or irrigation to a more productive use or its previous undisturbed state. This subcategory also includes studies involving the restoration of land that is damaged by natural phenomena, such as erosion, or impaired by industrial and urban processes.运用工程原理与设计方法，通过排水或灌溉，把湿地、海域、湖泊、沙漠或矿区的土地恢复为更具生产力的用途或原本未受扰动的状态。本子类别也包括修复受侵蚀等自然现象破坏、或受工业与城市活动损害的土地。
- PLL污染控制Pollution ControlStudies that use engineering principles and design to prevent or control air, water and solid waste pollution.运用工程原理与设计，预防或控制大气、水体和固体废弃物污染。
- REC回收与废弃物管理Recycling and Waste ManagementStudies involving the extraction and reuse of useful substances from discarded items, garbage, or waste. The process of managing, and disposing of, wastes and hazardous substances through methodologies such as landfills, sewage treatment, composting, waste reduction, etc.从废弃物品、垃圾或废料中提取并再利用有用物质，以及通过填埋、污水处理、堆肥、减量化等方式管理和处置废弃物与有害物质。
- WAT水资源管理Water Resources ManagementStudies that apply engineering principles and design to the planning, developing, distributing and managing the optimum use of water resources. Studies in this subcategory might include applied surface and groundwater hydrology, forecasting and control of quantity and quality of water or simulation and modeling of water resource systems.运用工程原理与设计，规划、开发、分配和管理水资源以实现最优利用。可涉及应用性的地表水与地下水水文学、水量与水质的预测与控制，或水资源系统的模拟与建模。
- OTH其他OtherStudies that cannot be assigned to one of the above subcategories. If the project involves multiple subcategories, the principal subcategory should be chosen instead of Other.无法归入上述任何子类别的研究。如果项目涉及多个子类别，应选择项目的主要子类别，而不是选择“其他”。
Judges are assigned by the subcategory you pick, so choose the primary one rather than "Other" where a project could sit in several. Source: Society for Science.评委是按你所选的子类别分配的，一个项目若能落入多个子类别，应选主要的那个，而不是「Other」。来源：Society for Science 官方。 Official page官方页面

Special-award rate 17.8%; combined 39.1%.专项奖率 17.8%；合并口径 39.1%。
These tier counts exclude 2025, whose award text is missing from the official database. The award-winning projects listed below do include 2025, recovered from the grand-award press release, so the two will not add up.层级分布剔除了 2025 年——该年官方库缺奖项文本。下方的获奖作品清单则包含 2025 年（从大奖新闻稿补回），因此两处数字不会相等。
The gap from the all-track rate of 30.3% is not statistically significant (Fisher exact p = 0.590).与全赛道 30.3% 的差距不具统计显著性（Fisher 精确检验 p = 0.590）。
