Working in her BioArtLab, Jalila Essaïdi discovered that cow manure provided both the base for a new, bio-degradable material and the chemicals required to produce it. She started by separating the waste, with the dry manure used to extract pure cellulose from the grass that cows eat. From the wet manure, she extracted acids used to create cellulose acetate, a natural liquid plastic. This was used to make fibers, which are later turned into fabric or bio-plastics, but it can also be freeze-dried to create an aerogel.
在她的生物艺术实验室里,贾丽拉•埃塞迪发现牛粪可以为一种新的、生物可降解物质提供主要成分和化学原料。她从分离粪便开始,将干粪中的纯纤维素提取出来,这些纤维素来自牛所吃的草。她还从新鲜的粪便中提取出用于制作醋酸纤维素这一天然液体塑料的酸类物质。醋酸纤维素可以用来制作纤维,纤维又是生成布料和生物塑料的原料。醋酸纤维素还可以通过冷冻干燥生成气凝胶。
The new material was named Mestic, from mest, the Dutch word for manure. Essaïdi claims that it has the same properties as plastic derived from fossil fuels, but is bio-degradable. Better yet, the degradability can be tweaked in the lab, making it possible to create materials that last for different periods of time depending on their purpose.
这种新物质被命名为Mestic,因为荷兰语中的粪便一词写作mest。埃塞迪解释道,它的原理与石油衍生物塑料一样,不同的是新物质是生物可降解的。更好的是,这种可降解性通过实验室处理可以改变,从而使原料的降解属性根据不同目的做出不同调整。
