中国是水产养殖第一大国，而汕头既是适合水产养殖的“海洋大市”，也是名闻遐迩的“海鲜名城”。以鱼制成的各式佳肴从渔船走上餐桌，俘获一众老饕。但制作海鲜美食的同时，无法避免废弃大量鱼骨、鱼渣等鱼废料，引发区域水体患上“富贵病”——富营养化。针对这一类食品固体废料处理的难点、痛点，广东以色列理工学院学生研究团队发表最新研究成果，成功让鱼类固体废料“化作春泥更护花”，探索有机农业新风口。
广以学生团队在老师指导下完成的论文《基于鱼固体废物的生物土壤日晒替代传统土壤熏蒸方法评估》（Assessment of using solid residues of fish for treating soil by the biosolarization technique as an alternative to soil fumigation）最近发表于知名学术期刊《清洁生产》（Journal of Cleaner Production）。《清洁生产》是一本国际性的跨学科期刊，专注于清洁生产、环境和可持续发展相关的研究与实践。该期刊在2021年的影响因子为11.072，属中科院SCI分区环境科学与生态学领域1区期刊（top）。

“我们的这一研究有几方面的创新！” 论文第一作者、广以生物专业研究生梁延翠介绍说，研究团队对本地产业进行实地考察，由此开展科学实验，开创性地使用鱼类水产残骸用作为添加剂运用到生物土壤日晒中的研究。对比传统化学熏蒸法，这种方法能有效避免化学残留物对水土和生物的污染。更重要的是，它既能将生物废料无害化，又能将其转化为肥料，实现效率、经济效益和可持续发展等方面的“多赢”。

这个年轻的团队由广以生物系教授Yigal Achmon带领。成员包括一名研究生梁延翠和七名本科生：李依璘、林煜、刘心涯、邹允凡、余珮镕、曾育颖、王修齐、王彦博。
从确定题目到学习仪器，从无数次的预实验到成功发表研究，这群科研“萌新”成长为科研创新的生力军，走向更广阔的星辰大海。
接下来，团队成员将走出温室、走入田野，前往汕头澄海正式开展试验田阶段的研究。梁延翠和她的队员们都对此信心满满：“我们期待为本地农业带来更多帮助！”
Waste isn't Waste When It Has a Value:
An GTIIT Student Team Published an Article on the Journal of Cleaner Production
Every year, China consumes over 2 million tons of fish products. The seafood turns into unique Chaoshan Cuisine including Fish Ball, Fish Rice and Fish Sauce, which are popular among people living in Shantou, a southeastern port city in China.
Inevitably, considerable amounts of fish waste rich in protein, fat and other organic matter, were generated during the process, which may pollute the aquatic ecosystem. Aiming at the problem, a Guangdong Technion – Israel Institute of Technology (GTIIT) student research team released an study on, recycling fish residues for treating soil.
The article titled "Assessment of using solid residues of fish for treating soil by the biosolarization technique as an alternative to soil fumigation", was published on the Journal of Cleaner Production, an international, transdisciplinary journal focusing on Cleaner Production, Environmental, and Sustainability research and practice. With an impact factor of 11.072 in 2021, this journal belongs to Region 1 of Environmental Sciences in SCI of Chinese Academy of Sciences.
Research Team in the Lab
"The study is the first known attempt to use separated fish residues as soil amendments for soil biosolarization (SBS), based on local industry," introduced by Liang Yancui, the first author of the article and GTIIT Biotechnology and Food Engineering Program (BFE) postgraduate student. Solarization used in the study, is an environment-friendly alternative to traditional soil fumigation, as it avoids hindering the herbicidal effect as well as causing secondary pollution.

The young team led by Yigal Achmon, Associate Professor of GTIIT BFE Program, consists of one GTIIT postgraduate student Liang Yancui, and 7 GTIIT undergraduate students including Li Yilin, Lin Yu, Liu Xinya, Zou Yunfan, Yu Peirong, Zeng Yuying, Wang Xiuqi and Wang Yanbo. The young researchers spent hundreds of hours working on pre-experiments design, equipment operation, data collection and group discussion, with the spotlight finally on the early-career scientists when they successfully published the article.
The team is now no longer the "Flower in the Greenhouse" (a Chinese Idiom means that people can't grow up without setbacks). They stepped out of the greenhouse, walking into the field study confidently. "We look forward to help with the local farmer!" said Liang.
