"Waste"是一个多义词，其含义根据语境和词性变化可分为以下五类解释：
1. 名词：废弃物或浪费行为
指未被充分利用的物质资源（如工业废料、生活垃圾）或时间/机会的无效消耗。联合国环境署定义其为"在特定时空条件下失去使用价值的物质"。例如："The factory produces chemical waste"（工厂排放化学废料）。
2. 动词：不合理消耗
表示对资源、时间或才能的非必要损耗。牛津词典指出其核心含义是"use carelessly, extravagantly, or without purpose"。例如："Don't waste water during drought"（干旱期间请勿浪费水）。
3. 环境科学术语
根据《巴塞尔公约》，危险废物特指"含有毒性、腐蚀性等特性，可能危害生态环境的废弃物质"。这类物质需要特殊处理，如医疗废物、核废料等。
4. 法律概念
美国《资源保护与回收法案》将废物定义为"被丢弃的物质，包括固体、液体、气体形态"，该定义直接影响企业的环保责任。
5. 近义词辨析
与"garbage"（厨房垃圾）、"rubbish"（英式日常垃圾）不同，"waste"更强调物质的价值流失过程。剑桥词典特别指出其包含"未能有效利用"的隐含意义。
词性：名词、动词、形容词
