神學論文：生物可降解聚合物材料的使用
研究和開發只是為介紹生物可降解聚合物材料的使用而進行的工作的一部分。這些材料的設計通常從概念應用開始。它可能被期望取代現有的材料，或補充一個。生物聚合物的應用包括(但不限於)醫藥、包裝、農業和汽車工業。許多已經被開發和商業化的材料被應用於以上的一類。可用於包裝的生物聚合物比指定用於其他用途的生物聚合物得到更多的關注。各級政府，特別是中國和德國政府，都支持生物降解包裝材料的廣泛應用，以減少目前被棄置在堆填區、佔用稀缺空間的惰性材料的數量。據估計，41%的塑料用於包裝，其中近一半用於食品包裝。生物聚合物的可再生和可降解特性使其在包裝上具有創新用途。這類產品的最終用途差別很大。在可降解塑料的環境中有很多問題，就像美國材料測試協會(ASTM)與國際標準組織(ISO)合作進行的測試研究一樣。

他們對可降解塑料的定義是:當可降解塑料暴露在某些環境條件下時，會發生顯著的反應。而這些可降解的塑料因此依賴於作用，從而導致物理和力學性能的損失。然而，在生物可降解塑料或聚合物的情況下，降解是由細菌和真菌等自然微生物的作用觸發的。這些可被微生物降解的塑料因此被稱為可生物降解塑料。還有可降解的、可氧化的可降解和可降解的可降解聚合物。這些物質可以被堆肥，因此以降解不可生物降解塑料的形式減少了對環境的影響。聚合物的生物可降解性是早在20世紀90年代就開始研究的一個重要方面。當時，美國有許多訴訟試圖了解什麼是生物可降解的，什麼不是。當時聚合物的生物降解被錯誤繁殖的企業使用。這些訴訟的產生是因為公司覺得其他公司在做誤導人的環境廣告。當時，生物降解的檢測方法也需要改進。然而，在當今時代，研究人員和業界也同樣從最初的衝突轉向了。

Research and development is only a portion of the work that is done in order to introduce the use of biodegradable polymer materials. The design of such materials usually begins with a conceptual application. It may be expected to replace an existing material, or to complement one. Applications for biopolymers have introduced include (but are not limited to) medicine, packaging, agriculture, and the automotive industry. Many materials that have been developed and commercialized are applied in more than one of these categories. Biopolymers that may be employed in packaging continue to receive more attention than those designated for any other application. All levels of government, particularly in China and Germany, are endorsing the widespread application of biodegradable packaging materials in order to reduce the volume of inert materials currently being disposed of in landfills, occupying scarce available space. It is estimated that 41% of plastics are used in packaging, and that almost half of that volume is used to package food products. The renewable and biodegradable characteristics of biopolymers are what render them appealing for innovative uses in packaging. The end use of such products varies widely.There are many issues in the context of degradable plastics, as seen in the case of the testing studies that were conducted by the American Society for Testing of Materials (ASTM) in collaboration with the International Standards Organization (ISO).

Their definition of the degradable plastics was that the degradable plastics would undergo significant reaction, when they were exposed to some environmental conditions. And these degradable plastics hence rely on the action, which results in the loss of physical and mechanical properties. In the case of the biodegradable plastics or polymers, however, the degradation is triggered by the action of natural microorganisms such as that of bacteria and fungi. These plastics that are degradable with microorganism’s action are hence are called as biodegradable. There are also photo degradable, oxidative degradable and water degradable polymers called as hydrolytically degradable. These can be composted and hence the environmental impacts in the form of the degradation of non-biodegradable plastics are reduced. The biodegradable nature of polymers is such an important aspect in research works done as early as in the 1990s. At this time, there were many lawsuits in the United States that attempted to understand what was biodegradable and what was not. The biodegradation of polymers in this time were used by businesses in wrong propagandas. The lawsuits arose because companies felt that other companies were engaging in misleading environmental advertising. At the time, it was also necessary for the methods of testing for biodegradation to also improve. However, in more current times researchers and the industry likewise have moved from these initial conflicts into.
