本文概述了芬兰技术研究中心（VTT）用于固体聚合物和包装材料生物降解性测试的方法。包装材料中所含的每种聚合物的生物降解性应分别进行试验。水生有氧和厌氧测试，并在特定情况下。酶试验用于筛选目的。讨论了水中需氧试验的应用-自动Sturm试验（OECD 301 B; ASTM D5209）和VTT顶空试验以及厌氧试验（ASTM D5210）。总结了三种堆肥试验方法及其应用。这些测试被认为是重要的，因为它们可以用来模拟在现实生活条件下的生物降解性。需要几个测试来确定聚合物在真实的条件下的命运，并研究其在不同环境中的生物降解性。聚合物在自然界中完全生物降解所需的时间是不可能通过实验室测试来预测的，应该在体内进行研究。
This paper gives an overview of the methods used at the Technical Research Centre of Finland (VTT) for the biodegradability testing of solid polymers and packaging materials. Biodegradability of each polymer included in the packaging material should be separately tested. Aquatic aerobic and anaerobic tests and, in specific cases. enzymatic tests are used for screening purposes. The application of aquatic aerobic tests-an automated Sturm test (OECD 301B; ASTM D5209) and a VTT headspace test as well as an anaerobic test (ASTM D5210)-is discussed. Three composting tests and their applications are summarized. These tests are regarded as important because they can be used to simulate the biodegradability under real-life conditions. Several tests are needed to determine the fate of the polymer under real conditions and to study its biodegradability in different environments. The time needed for complete biodegradation of polymers in nature is impossible to predict with laboratory tests and should be studied in vivo.
