Poly Lactide﹝PLA﹞
Poly Lactide﹝PLA﹞,是一種新的多用途可堆肥的高分子聚合物，是由百分之百可再生資源玉米、木薯提取出的澱粉，甘蔗和甜菜提取的糖和秸稈等提取的纖維素, 或稻殻、豆莢等經過發酵、脫水等過程獲得乳酸所製成。

PLA, 聚乳酸已經廣泛應用在生物醫學工程上，用作手術縫合線、骨釘和骨板等。使用 PLA 聚乳酸做的手術線無需拆線，可以緩慢水解為乳酸被身體代謝掉,一般的降解時間需要半年到兩年。
PLA 聚乳酸的應用現在已經超出醫學的範圍，廣泛應用於一些常見的物品，如：包裝袋、農作物用薄膜、紡織纖維和餐具。PLA塑膠與傳統塑膠最大差異點，在於PLA塑膠品可被微生物完全分解成植物生長所需的二氧化碳與水，對環境極為友善，其「天然」、「無毒」、「環保」、「永續」等四大特性，符合「取之於自然，回歸於自然」的資源生命循環哲理。
PLA,Polylactic acid life cycle :
Renewable - Sustainable - Environmentally friendly - Polymer - Biodegradable - Bioplastic - Starch - Sugars - Resin - Sun Light - Oxygen - H20 - CO2 - Land Fill - Life Cycle
PLA is processed from the starch of plants such as corn, sugar cane, bagasse, sugar beet. In order to make it environmentally friendly and sustainable,Polylactide is biodegradable which decays as a result of exposure to the sunlight and oxygen and then decomposes forming carbon dioxide and water, PLA was extracted, fermenting and polymerizing, which present no danger to the environment.
LOURDES commit to provide eco-friendly, natural, recyclable, biodegradable, non-toxic, sus tainability and green trade for all to reduce the impact of our consumption on the earth and help to create a better and sustainable world.
