科学家将咖啡废物变成可生物降解的包装,以减少垃圾填埋,延长食物保存期。 Scientists turn coffee waste into biodegradable packaging to reduce landfill and extend food shelf life.

来自俄勒冈州立大学和韩国的研究人员开发了一种方法,将耗尽的咖啡地转化为生物降解食品包装,有可能延长产品储存期。 Researchers from Oregon State University and South Korea have developed a method to convert spent coffee grounds into biodegradable food packaging, potentially extending product shelf life. 这一过程涉及乙醇预处理和对乙酸处理,将废物转化为无害生态的材料,减少填埋场废物和甲烷排放。 This process, involving ethanol pretreatment and peracetic acid treatment, transforms waste into eco-friendly materials, reducing landfill waste and methane emissions. 这些材料可用于各种包装应用,但还需要进一步研究,以提高其对光、湿度和氧的抗力。 The materials can be used in various packaging applications, but further research is needed to improve their resistance to light, moisture, and oxygen.
