We have an unmatched track record in helping generate fuel gas from waste materials. The twin-interchanging fluidized-bed (TIF) incinerator operating at Incheon Airport is just one example of our ground-breaking capabilities. Our expertise covers every aspect of the organic sludge treatment process, ranging from solidification to carbonization and incineration, thus giving us an important competitive edge in the business of
turning waste into energy sources.
We are also highly differentiated in the area of food waste management sector. By using diverse techniques including aerobic composting, adding of wastewater,and anaerobic digestion, we have reported an unmatched track record in the design and construction of facilities for making use of food waste materials.
Twin-Interchanging Fluidized-bed Incinerator, TIF
Fluid sand within the incinerator revolves around without the help of any mechanically moving parts. The incinerator gains its momentum from the difference in the flow of air supplied through the bottom of the incinerator. A furnace hearth and innovative deflector play an important role in this intricate process. This type of incineration can dispose of not only regular waste from households but also wastewater sludge whose caloric value is very low. Recently, we started to offer a fluid sand mixed incineration system which can incinerate sludge by mixing it together with waste of high caloric value without the need for any fuel.

Thermal cracking and gasification of waste takes place in the fluidized-bed at a temperature of 550 to 630℃. As a result, uniform gas can be obtained through this innovative process. The next step is for the generated gas to be sent to a cyclone melting furnace where it is mixed with air before being combusted at a temperature of 1,300~1,450℃. Ash from the combustion is then melted into slag, during which any dioxins are removed.

RDF(Refuse Derived Fuel) Plant
RDF can turn urban waste into solid matter, easy-to-transform fuel or other eco-friendly resources, leaving only a minimum impact on the environment. These materials can be stored over a long time without causing secondary pollution or giving off any odors. They contain a large amount of thermal energy (enough to replace part of the fissile fuel used at thermal power plants), thus helping ease the problem of global warming.

Facilities to dispose of food waste and wastewater altogether
We have plenty of experience in constructing and operating facilities to dispose of food waste and wastewater altogether. Our substantial expertise in fostering optimal hydrolysis and acid fermentation conditions and injecting fermented fluid into the digestion tank has made it possible for us to improve the overall efficiency of digestion and gas production and, as a result, reduce operating costs.

Biogas recovery systems
Hyosung Ebara Engineering is pioneering a new frontier in sustainable energy generation from wastewater treatment facilities and landfill sites. Its areas of expertise include reducing sludge through increasing efficiency levels at digestion tanks and generating electricity using biogas emanating from tanks. It is also planning to expand into alternative energy sources such as photovoltaic cell generation and landfill gas.
