一、您的关注
材料作为社会经济发展的物质基础和先导，对推动人类文明的进程起着及其重要的作用。随着经济和社会的发展，对材料及产品的需求也越来越大。随之而来的在资源利用和开发的技术水平、深度和广度，以及资源效益、经济效益、环境效益上的问题也日益突出。正是在这种背景下，近几年国际上提出并发展了生态环境材料（Eco-Materiel）这一概念，并成为材料科学发展的***方向和热点前沿之一。相对于传统材料，生态环境材料的显著特质集中于零***物质、绿色环保、高材料循环性以及高材料效能等四方面。它的发展有助于解决资源短缺、环境恶化等一系列问题，促进社会经济的可持续性发展。
生态环境材料的研发、推广、应用和进出口贸易都涉及到材料的生态环境安全性能的检测和评价。国际上通用的检测内容有材料特性鉴别、生物降解、崩解、生态效应和堆肥质量等五方面。如：
ASTM D6400 - 12 Standard Specification for Labeling of Plastics Designed to be Aerobically Composted in Municipal or Industrial Facilities
ASTM D6868 - 11 Standard Specification for Labeling of End Items that Incorporate Plastics and Polymers as Coatings or Additives with Paper and Other Substrates Designed to be Aerobically Composted in Municipal or Industrial Facilities
EN 13432:2000 Packaging -- Requirements for packaging recoverable through composting and biodegradation -- Test scheme and evaluation criteria for the final acceptance of packaging
AS 4736-2006 - Biodegradable plastics - Biodegradable plastics suitable for composting and other microbial treatment
