CARBOFER® - Details

Is a patented TECHNOLOGY a new process derives value from waste and /or by-products.

Developments of waste Management Practices

We have an increasing environmental and economic pressure to reduce waste (by-products), being dumped to landfill.

Many of the Fe-metal or Fe-oxide containing waste materials in form of sludges and dust have a good value if conditioned and recycled. The CARBOFER® process supplies an optimised practice for the treatment of various ferriferous waste and by-products like oily mill scale, bag house and / or blast furnace dust and sludges, used refractory bricks or ladle furnace slag, shavings and scale from upstream steelmaking plants, sludges and dust from honing, grinding, boring, milling and polishing often also contaminated with organic loaded hazardous cutting fluids.
In general, steel plants produce a larger amount of a variety of wastes / by-products. A great part of the bulk slag and steel spillages are processed. The processing supplies a saleable synthetic (building) - material and also steel skulls. Most other by-products have fallen into the category of WASTE and been land-filled, either with or without some decontamination process.
Processing (brief information):
One or various oily waste in form of sludge are combined / mixed with specific selected dust components to form the CARBOFER® product. The "product" is screen-able, free flowing and inject-able into a melting unit like blast furnace or electric arc furnace. Ladle slag and / or refractory ground waste are mixed and added to the "product’’ as a substitute material replacing for example lime and injected commonly together with the "product" into the furnace.

Injection CARBOFER ® into the blast furnace.
The waste or the by-product of oil-contaminated mill scale sludge is recycled in an ecologically, technically and economically satisfactory manner by using the CARBOFER-process by injecting the "product" via the tuyeres into the high-temperature zone of the blast furnace. Due to an available range of temperature (of about 1.800 to 2.400 °C) and the blast furnace reducing atmosphere a release of dioxins and furanes, as well as de novo synthesis, is not possible. The blast furnace supplies optimal conditions to destroy organic hazardous waste.
