The company was formed to conduct the business operation for the solid waste recycling and recovery the metal/steel from the existing steel slag producing by LICB Group of companies.
|Steel Slag and The Environment||Worldwide||Technology||Business Model||Production Process|
Steel slag is a byproduct from either the conversion of iron to steel in a basic oxygen furnace, or the melting of scrap to make steel in an electric arc furnace. Like other kind of waste material, if the steel slag without further processing, they were non-decaying and will remain in the environment for hundreds and perhaps thousands of years. This situation combined with the ever increasing consumer population and demand, has resulted in a waste disposal crisis.
Research reported by Hamzah (2002) that steel slag amounts to approximately 10% of liquid steel output in a typical steel producing plant and it indeed represents the major waste items generated from the steel making industry. The cost for committing to the environmental friendly disposal plan can add tremendous burden to the industry.
The fact to resolve the waste disposal problem and reduce cost, recycling of these materials and engineering them into useful products are essential and that was also align with Malaysia government’s effort in developing green business environment technology.
Steel slag’s attribute in highly compressed structure, it resulted in very dense and hard materials. At the moment, this kind of engineering waste material widely innovatively and effectively use into road construction in various countries including Malaysia.
Fortunately, because of this type of engineering waste is high basicity and being cooled properly can exhibit cementing property; ground steel slag has been used in several different cementing systems. The use of steel slag in these cementing systems results in some advantages over conventional cements. Certain of country like China, they are further innovate the steel slag waste into building material i.e. cement block.
However, the use of steel slag as a cementing component should be given a priority from technical, economic and environmental considerations.
In America, steel slag widely use in cement production and in year 2008, its total usage around 2.7million metric tons. This products has substantially increase on demand and it was proven by SCA (Slag Cement Association of America) as environmental friendly and the 3.4 million metric tons of slag used in 2007 represents the following environment benefits :-
In summary, the waste material of steel slag can be engineering be used in the following aspects and that is also the principal activities of the company:-
- Recycling/extraction of remaining material;
Malaysia mainly used for low economic sector in land filling.

The processing technology was applied by the company was a kind of Japanese Process Technology which introduced by the joint venture partner TITCO. This technology was invented by its Japanese partner, Nippon Magnetic Dressing Company and it has the following unique advantages:-
On technology, the company applied multiple re-circulated process of crushing (coarse, medium, fine), extractions (magnetic separation and gravity separation), screenings and grindings to super fines. The ultimate finished products would be able to suit different kinds of appliance.
This technology would be able to create maximum value for the company in terms of financially and environmentally. This technology has proven by TITCO in its Steel Slag Plant situated in Shanghai and Suzhou.
The business model of the company set-out as below :-
|Hot steel slag would deliver to the processing plant dumping area by LICB group of companies. The company’s water sprayer would pour the water to cool down the temperature before putting into the conveyor system|
|Cooled Ir-regulate Size of Steel Slag Cooled Steel Slag would put into the conveyor system to send over to the crushing plant|
|After screening, slag would send for second/third round crushing/grinding/cutting into different size for different appliance. This process would on-repeating till reach the specification.|
