Steel is a versatile material that plays a major role in everyday life. At the same time, steel makes up the largest category of metals in the industrial waste streams due to the byproducts produced in its manufacturing process.

Slag is the primary byproduct of steelmaking. As a result of growing environmental awareness, steel slag is now highly regarded as a recycled material that can reduce environmental impact due to its resource-conservation and energy-saving properties.

MEKA is designing and manufacturing customized steel slag processing and metal recovery plants for each project-specific purposes.

Our portfolio; MEKA offers stand-alone machines, process solutions, turnkey plants, separation and sorting technology, and control and automation solutions perfectly tailored to individual requirements.

Metallic Recovery: Allows for the recovery of virtually all residual metallics from the slag;

  • MEKA processing plants have high metallic recovery rates. Our plants utilize state-of-the-art magnetic separation equipment to maximize the recovery of metallics from the raw slag.The processing plants include the latest technology in crushing and screening plant design to cleanly separate the slag and metal into different sized fractions depending on customer specifications and market demand.


Slag recovery: Turning a waste disposal problem into a business opportunity;

  • The slag-co product produced from the metallic recovery process fulfills important functions as construction materials for roads, ports, airports, and also as an environmental material for restoring or improving marine, soil, and other environments,
  • Because of its hydraulic property and the large bearing capacity, steel slag has superior wear resistance, when used in the asphalt layer, also makes roads safer to drive on by offering better skid resistance,
  • Is approved as an agricultural aggregate, and slag processing is generating a sellable product that reduces landfilling needs-improving sustainability and creating additional value.
