To lessen marine flotsam and jetsam, which cause serious ecological contamination in the ocean, scientists at the Korea Establishment of Structural Designing and Building Innovation (KICT) have fostered an innovation for diminishing drifting garbage in streams.
Since the stream is the primary transportation channel for land-started marine trash, the exploration group led by Dr. Sang Hwa Jung sent off a living lab project that included residents of nearby states, neighborhood residents, and specialists.
Chungcheongnam-do (otherwise called Chungcheongnam Territory and Chungnam) has the third longest shore in South Korea, with a total of 500 waterways and streams in the locale. The amount of marine flotsam and jetsam in Chungnam has been expanding consistently, and marine trash streaming in through waterways represents around 61.2% of the aggregate.
“Because garbage entering the sea is difficult to collect due to its wide spread nature and contains impurities (salts, mud, etc.) that increase the cost of cleaning-up process, it is necessary to intercept and collect it from rivers before it enters the sea, by combining traditional river engineering with advanced technologies such as information technology and AI, these technologies can solve local problems as well as global environmental problems.”

In like manner, Chungnam introduced and worked an interceptor office in 2019, but underlying harm happened during weighty rains and floods, which should have been settled. The fundamental justification behind this harm is that the construction and elements of the interceptor were not planned in light of the math and attributes of the stream (water level, width, stream rate, water level change, and so forth.).

As well as guaranteeing the primary security of the interceptor, the venture’s key targets were to create and test an interceptor office with assortment support capabilities for accommodation of assortment, responsiveness to changes in water levels of streams, and observing capabilities to distinguish suitable assortment timing.
Dr. Jung’s exploration group directed research in the accompanying stages: portrayal of the objective stream, determination of the ideal waterway point, plan of the obstruction, support heaps and associations, and location development of the interceptor office. Specifically, the plan and development of the interceptor office were completed mutually with Foresys Co., Ltd., and the mathematical model examination and full-scale observational tests were completed at the Waterway Analysis Center in Andong, Gyeongsangbuk-do.
The Stream Examination Center covers an area of 192,051 m2. The middle has the biggest testing framework in South Korea, with a stream supply limit of up to 10 m3/s, giving an ideal experimental testing foundation.
Using the results of this review, an interceptor office was developed and placed into operation in May 2023 on the Yugu-cheon (otherwise called Yugu Stream), situated in Gongju, Chungnam. During the venture, an observing framework was constructed in light of the assessments of nearby legislatures to decide the suitable assortment time and really take a look at continuous data on the activity status.
In light of the picture information gained through this, an emotionally supportive network likewise evolved. It utilizes man-made brainpower (computer-based intelligence) to examine the sum and organization of drifting garbage in the stream and decide the suitable assortment cycle.

“Trash that enters the ocean is challenging to gather because of its wide spreading nature and contains contaminations (salts, mud, and so on) that increase the expense of the tidying up process, so it is important to capture and gather it from waterways before it enters the ocean,” said Dr. Jung. He additionally stressed that “by joining customary waterway design with cutting-edge innovations, for example, data innovation and man-made intelligence, these advances can take care of neighborhood issues and worldwide ecological issues, too.”
The task is exceptionally expected by the local neighborhood for the living lab-based combination of innovation advancement and maintainability. The interceptor office and checking framework introduced at Yugu-cheon will be active and consistently improved until 2026, and conversation with applicable nearby states is in progress to spread the outcomes to different streams from now on.
