Urban mining, rediscovery of waste

Along with the growing demand for scarce metal, the deletion of natural resources has been accelerated. Urban mining refers to the industry which collects expensive and scarce metals from discarded home appliances or industrial waste as well as provides it as industrial sources. And it has garnered a lot of attention as an emerging industrial area that can tackle the depletion of resources. Metals like gold and silver are used for electronic circuit boards and BGA chips embedded in widely used electronic devices. In order to recover the raw materials and provide the metals to other industrial areas that need mineral resources, the reusable mineral resources are collected. Among the recovered materials, gold is made into gold bars by going through sophisticated refining process. A variety of different metals can be obtained from scrapped cars. The components, which are gained while taking apart a scrapped car, go through the reinforcement process. And they are reproduced and provided as secondhand components. The components which are impossible to be used again are moved to scrapping facilities and shredded. Moreover, a domestic research team has developed a display recycling technology. By introducing an automated system to the works which used to be done manually, the efficiency of scrapping and selecting has been strengthened. We introduce urban mining, which can accelerate natural circulation and increase economic benefits by making use of the valuable resources.

Rise of smart bacterial detection technology

Food poisoning is one of the issues that has been in the spotlight every year. It is caused by contaminated water and food, and it is one of the threatening diseases that is harmful to people's health. Along with the external factors like climate change and fine dust, the risk of propagation of germs has increased. So it is important to put more efforts on enhancing hygiene control for food. Therefore, bacterial detection technology, which enables the general public to check the possible bacterial infection, has garnered a lot of attention. A research institute has developed a smart device for detection of E.Coli, in order to enhance safety of people's dietary life. The device has been provided to a lot of different areas, including meal service providers, small food processing businesses and cafeteria businesses. As the detector is more convenient to use, even the general public can easily check the possible propagation of E.Coli. And a device that can detect the bacteria in water within a short period of time has been developed. The device can conduct a bacteria test, which used to take 24 hours, only within three hours. And it can be used by anyone. A portable smart IoT bacteria detector, which can check the harmful substances contained in food anytime, at any place, has been developed. It was developed based on the spectroscopic technology. As the device has a compact size, the measuring process which took place in a laboratory can also be carried out conveniently in daily lives. We look into bacterial detection technologies which has contributed to producing and distributing food more safely.

Korean laver as emerging K-Food

Laver has gained recognition as one of most popular side dishes for a long period of time. It has led the Korean Wave by obtaining popularity as K-Food. And it has risen as global food that has captivated the tastes of people all around the world.

The laver harvested in the middle of the sea is rich in calcium, so it can reduce the risk of osteoporosis. Also, the alginate contained in laver can prevent obesity. Moreover, as the entire process including production, processing and distributing has been done in the domestic field, a continuous increase in exports has boosted the development of the local economy. MANJUN SEAWEED, which has received support from the federation, is a manufacturer of seasoned laver products. And by analyzing the ingredients of laver, a lot of researches have been actively carried out by the company to develop a variety of laver products. Various laver products developed by the company have been provided at overseas stores and it has enjoyed a continuous increase in demand. We report on the Korean Federation of Laver Businesses, which has strived hard to popularize the excellence of Korean laver as well as the growing popularity of Korean laver in the global market.
