Scientists at Nanyang Technological University (NTU) in Singapore have found a new way to handle food waste.
新加坡南洋理工大学(南大)的科学家发现了一种处理食物垃圾的新方法 。
They are turning unused durian fruit coverings, or husks, into antibacterial bandages.
他们将未使用的榴莲壳制成抗菌绷带 。
The researchers took fibers from the fruit's husks after they were cut and dried.
研究人员先把榴莲壳切片和干燥,之后从中提取纤维素粉 。
Then they mixed the fibers with a liquid called glycerol.
然后,他们将纤维素粉与一种名为甘油的液体混合 。
This mixture becomes a soft substance called a hydrogel, which is then made into bandages.
这种混合物变成一种叫做水凝胶的柔软物质,然后被制成绷带 。
The fruit's husks make up more than half of a durian's structure.
榴莲的外壳占榴莲结构的一半以上 。
They are usually thrown away and burned, which adds to environmental waste.
它们通常被扔掉和焚烧,这增加了环境垃圾 。
William Chen is director of the food science and technology program at NTU.
威廉·陈是南大食品科技项目主任 。
He said, "In Singapore, we consume about 12 million durians a year, so besides the flesh, we can't do much about the husk and the seeds and this causes environmental pollution."
他说:“在新加坡,我们每年消费大约1200万榴莲,所以除了果肉,我们对果壳和种子无能为力,这就造成了环境污染 。”
Chen added that the technology can also turn other food waste, such as soybeans and grains, into hydrogel.
陈补充说,这项技术还可以将大豆和谷物等其他食物垃圾转化为水凝胶 。
The hydrogel bandages can keep wound areas cooler and more moist than normal bandages which can help speed up healing.
相比普通绷带,水凝胶绷带能保持伤口更凉爽湿润,有助于加速伤口愈合 。
The researchers say using waste materials and yeast for the antibacterial bandages is less costly than using normal bandages.
研究人员表示,使用废弃材料和酵母制作抗菌绷带比使用普通绷带的成本更低 。
The antibacterial substances in those bandages use more costly metallic compounds like silver or copper.
普通绷带中的抗菌物质使用了更昂贵的金属化合物,如银或铜 。
Fruit seller Tan Eng Chuan said he goes through as much as 1,800 kilograms of durian each day during durian season.
水果商谭恩川说,在榴莲季节,他每天要处理多达1800公斤的榴莲 。
He said being able to use the parts of the fruit that are usually thrown away would make enjoying durian, in his words, "more sustainable."
他说,能够利用榴莲中通常被扔掉的部分,用他的话说,会让吃榴莲“更可持续” 。
