In the fiercely competitive steel industry, cost control and environmental compliance have become twin shackles holding back progress. Among these, the disposal of oily grinding sludge and sludge residue—long overlooked as a “hidden cost sinkhole”—has been quietly devouring enterprise profits. Traditional treatment methods often lead to high-value oils being incinerated or discarded with the sludge, while oily grinding dust, categorized as hazardous waste, imposes overwhelming treatment costs on businesses.

Just as steel producers were seeking a breakthrough, a game-changer quietly emerged.
Recently, Nanjing KERUN, in collaboration with a leading domestic hydraulic equipment manufacturer, successfully passed the pre-acceptance of its newly co-developed centralized chip treatment system at a top-tier steel group in China. Through technological innovation, the system achieved a dual breakthrough in “used oil recycling + hazardous waste reduction”, opening a new pathway for cost reduction and green development across the steel industry.
Part 01 Three Core Achievements Reshaping Cost Structures in the Steel Sector
01：Efficient Oil Recovery: Reduce New Oil Procurement by 35%
KERUN’s centralized chip treatment system utilizes mechanical compression to extract oil from oily grinding sludge, achieving an oil recovery rate of ≥95%. The recovered oil can be directly reused in production lines, cutting down new oil purchases by approximately 35% annually. The resulting economic savings significantly reduce raw material expenditures.
02：40% Reduction in Hazardous Waste at the Source: Slash Disposal Costs
With its high compression ratio, the system reduces hazardous waste mass at the source by over 40%. This directly cuts down storage, transport, and disposal volumes—yielding substantial savings in hazardous waste processing.
03 ：Zero Pollution, Fully Compliant: A Strong Environmental Safeguard
Amid tightening environmental regulations, this system is designed and operated to meet full compliance standards. Its zero-emission performance reinforces sustainable operations and secures long-term regulatory confidence.
