DS Danseok , a resource recycling energy specialist, announced on the 18th through a public notice that it has acquired a patent related to a waste oil treatment system.
The patent is for an 'automated system for recovering high-purity waste oil from oil cans of waste cooking oil and continuously separating and sorting scrap metal and foreign substances', and it automates the refining process for using waste cooking oil supplied in can form as a raw material for bioenergy.
Waste cooking oil, typically generated from restaurants and other sources, is disposed of in cans. To recycle it into raw materials, the cans must be fed into a refining process. This typical refining process not only requires additional manpower during the refining process, but simply squeezing the cans to extract the waste cooking oil results in a relatively low recovery rate, and handling foreign matter and can scrap is also difficult.
To resolve these issues and improve process efficiency, DS Danseok has been pursuing independent technology development, and announced that it has now completed patent acquisition following its patent application in 2022.
DS Danseok's waste oil treatment system is a smart process that ▲reduces simple operation manpower to 1/3 through an automated process using robots ▲increases the recovery rate and purity of waste cooking oil through can crushing, filtration, and heating technology ▲optimizes energy use through improved heating methods ▲and efficiently separates and sorts waste generated during the process and recyclable waste resources (steel scrap, plastic, etc.).
A DS Danseok official said, “This patented system is a process that can process 80,000 tons of waste cooking oil per year, and has been applied to our production line since 2023 after technology development,” and “We are the first in Korea to complete the entire process from process introduction to patent acquisition, and based on this, we will strengthen the competitiveness of our bioenergy business, such as expanding our production base.”
