This can not only mitigate the excessive exhaustion of natural depletive mineral deposits but also close up the open loop of material flow for shaping a recycling-oriented society, an important issue both in sustainable waste treatment and natural resource conversation. The generation of inorganic wastes such as residues from MSW and industrial incinerators, sludge from sewage treatment plants and water-works, fly ash from coal-firing electric plants, sediments from reservoirs, dust and slag from steel mills, as well as wastes from pavement removal and construction—all these waste streams provide an excellent opportunity for replenish our natural resources. Currently diverse techniques have been developed to recycle the said wastes into constructional materials. A few key techniques to be noted here include the preparation of eco-cement, the preparation of artificial aggregates by melting or by sintering, and the production of refractory by application of sintered aggregates, and the development of composite porous material and functional eco-ceramic (FEC) material. This study here tries to develop, adopting China clay and wastes of residues and sludge, a novel eco-material that is functional to control the surrounding moisture and absorb odorants and VOCs in the air by its porous structure, and is able to decompose them by pregnant TiO2 at the surface of the material. The Integrated study on “Preparation of Functional Eco-Ceramic (FEC) derived from Wastes of Sludge and Incinerator Residues” is divided into three phrases: Phase I: Preparation of Functional Waste-derived FEC—Study on Characteristics and Selection of the Composite Materials Phase II: Study on Development of a Functional Waste-derived FECs—their Mechanism and Preparation Techniques Phase III: I --In Plant Demonstration Study on Preparation of Functional Waste-derived FEC In Phase I, The raw materials include but not limited to, China clay, sludge, incinerator residues, CaO-containing wastes (ex. blast furnace slag), volcano ash, (Kanumatuti, containing allophane), diatom earth, and vermiculite, as well as TiO2 are to be characterized, and their feasibilites of combination are to be studied as for the screening and a basis for subsequent preparation study. In Phase II, Based on the results obtained form the previous characteristic study, the development of a functional eco-ceramic materials, their composite mechanism, functional characteristics are to be studied and evaluated by experiments designed by Taguchi Method. In Phase III, Based on the composite formulations and operational conditions, actual sized-samples are to be prepared and studied in-plant, focused on the functional characteristics of the resultant eco-ceramic materials, evaluation of the material properties and their eco-functions. The functional eco-ceramic (FEC) material derived from wastes of sludge and Incinerator residues is both environmental-friendly and economic-beneficial that can find their demand in green supply chain, and achieve the realization of sustainable development. ; 研究期間 9708 ~ 9807 |
