| Summary: | 碩士 === 國立中山大學 === 高階經營碩士班 === 95 === BOF slag is a co-product generated from Basic Oxygen steelmaking process with annual production of 1.3 million tons approx. Because of its unique physical and chemical properties, it was considered as waste in the past and dumped to the ocean. After research and development, the BOF slag was used as sea-shore embankment and landfill material. Then it was registered as a product and was further used as land filler of temporary roads and parking lots. For now, BOF slag can be used as engineering materials such as asphalt concrete aggregates and Controlled Low Strength Material. Advancing waste recycling to promote resources optimization is an essential factor to industrial sustainable development. It also meets the global trends of sustainable use of resources and sustainable development of economy and society.
Investigating the process of BOF slag resourcilization, it is concluded that the center of the development frame of recycled products is waste resourcilization. The steps to completely solve pollution problems including: input of human and natural resources, basic research and development, and finally converting waste into products. Meanwhile, governmental regulations must not be violated. Relevant regulations, domestic and international experiences and practices, and market investigation must be considered to confirm market need and opportunities for development. After the above are finished, the work team can be formed to start research and development.
The recycled product development process can be divided into 7 major stages, including basic properties analysis, selection of application direction, technological research and evaluation, economical feasibility analysis, trial production and market testing, certification and specification modification, commercialization and promotion.
