현재 CDM사업 등록은 대부분 에너지, 화학공정, 제조공정 분야에서 이루어지고 있다. 그러나, 무기질 자원재활용을 통한 CDM사업 등록은 그렇게 많지 않은 실정이다. 본 논문에서는 국내 무기질 폐기물의 재자원화를 통한 CDM사업 등록 가능성을 알아보기 위하여 국내외 CDM사업 현황 분석 및 적용사례를 조사하였다. 조사결과 CDM사업 등록 사례는 대량으로 활용할 수 있는 산업 중의 하나인 시멘트산업의 원료 대체화 분야에서 다수의 등록이 이루어진 것으로 조사되었다. 우리나라에서의 CDM사업 적용 전망은 산업의 규모, 무기질 자원 활용 산업 및 온실가스 배출량을 분석하고 대량으로 활용할 수 있을 정도로 지속적으로 발생되는 우기질 폐가물의 현황 등을 면밀히 검토해야 할 것으로 판단된다.

Accelerated carbonation is a technique that can be used as a CCS technology for $CO_2$ sequestration of approximately 5~20% in a stable solid through the precipitation of carbonate. An alkaline inorganic waste material such as ash, slag, and cement paste are generated from incinerators, accelerated carbonation offers the advantage of lower transport and processing costs at the same generation location of waste and $CO_2$. In this study, we evaluated an amount of $CO_2$ sequestration in various types of inorganic alkaline waste processed by means of accelerated carbonation. A quantitative evaluation of $CO_2$ real sequestration based on a TG/DTA analysis, the maximum 118.88 $g/kg_{-waste}$ of $CO_2$ in paper sludge fly ash, the maximum 134.46 $g/kg_{-waste}$ of $CO_2$ in municipal solid waste incinerator bottom ash, the maximum 9.72 $g/kg_{-waste}$ of $CO_2$ in industrial solid waste incinerator fly ash, and the maximum $18.19g/kg_{-waste}$ of $CO_2$ in waste cement paste.

Shredded waste newspapers, waste acrylic raw fibers, and urea-formaldehyde (UF) adhesives, at 10% by weight on raw material, were used to produce recycled waste paper-waste acrylic raw fiber composite boards in laboratory scale experiments. The physical and mechanical properties of fire retardant treated recycled waste paper-waste acrylic raw fiber composite boards were examined to investigate the possibility of using the composites as internal finishing materials with specific gravities of 0.8 and 1.0, containing 5, 10, 20, and 30(wt.%) of waste acrylic raw fiber and 10, 15, 20, and 25(wt.%) of fire retardant (inorganic chemical, FR-7^®) using the fabricating method used by commercial fiberboard manufacturers. The bending modulus of rupture increased as board density increased, decreased as waste acrylic raw fiber content increased, and also decreased as the fire retardant content increased. Mechanical properties were a little inferior to medium density fiberboard (MDF) or hardboard (HB), but significantly superior to gypsum board (GB) and insulation board (IB). The incombustibility of the fire retardant treated composite board increased on increasing the fire retardant content. The study shows that there is a possibility that composites made of recycled waste paper and waste acrylic raw fiber can be use as fire retardant internal finishing materials.

Along with the expansion of industrial activities, the quantity of industrial waste sludge is increasing, and the treatment/disposal of wastes is a social problem regarding the preservation of the environment. In particular, recycling the sludge as a raw material is actively required considering the situation of Korea, which is poor in natural resources and energy. Lime is a necessity for treatment of waste sludge, which often can be made recyclable by lime treatment. In this thesis, a brief description has been given of my views on the ordinary treatment of waste sludge and the effective use of inorganic industrial waste sludge focusing on lime.

To prevent energy waste in buildings used heat insulator. Heat insulator materials can be classified inorganic and organic. The organic material is be toxic gas emission, when a fire occurs. And it has lower water resistance. The inorganic material is heavy and worse thermal performance than organic materials. This study focused on thermal conductivity and density of inorganic foam material for using industrial by-products materials.

Cow's liquid manure (CLM), an animal waste, was treated by a batch algal culture to remove inorganic nutrients. CLM used in this study was especially high in concentrations of inorganic nitrogen and phosphorus. The optimum dilution ratio of the CLM for maximum algal growth was 1:25. Ninety five percent of inorganic nitrogen and 100％ of inorganic phosphorus were removed from the CLM with a dilution ratio of 1:25.

건설폐기물의 재활용방법 중 하나는 폐콘크리트 재생골재를 도로포장재료로 활용하는 것이다. 하지만 재생골재에 대한 많은 연구와 기술개발에도 불구하고 생산공정에 포함된 이물질 때문에 실제 도로포장재료로의 적용은 미비한 실정이다. 본 연구에서는 재생골재내에 포함된 이물질의 특성에 따라 무기이물질과 유기이물질로 구분하였으며 , 각 이물질이 포장 공용성에 미치는 영향을 제시하였다. 또한 재생골재내에 포함된 무기이물질 함유량과 압축강도와의 관계, 유기이물질 함유량과 수정 CBR과의 상관관계를 통하여 도로포장층인 린콘크리트 기층과 보조기층에 적용 가능한 이물질 함량기준을 제시하였다. 린콘크리트 기층에는 무기이물질 함유량 질량비 10% 이하, 입상재료 보조기층에는 유기이물질 함유량 부피비 2% 이하일 때 재생골재를 포장에 적용 가능한 것으로 나타났다.

Recently, the exhaustion of resource and environmental damage is serious due to the global warming because of the CO₂ exhaust and each type the natural aggregate picking described below. meanwhile, The rest is the actual condition gone to the dumping ground that there is nearly no use which the waste glass can recycle and it is recycled. This research applied the waste glass as the cement substitute material the inorganic binder and coares aggregate substitute material. It utilizes the substitute material of the cement according to it and natural aggregate and tries to develop the environment-friendly artificial stone. The inorganic binder used the blast furnace slag, red mud, and fly ash. The straight type steel fiber, PVA fiber, PA fiber, and cellulosic fiber were used with a kind of fiber. As to the experimental item according to it, the compressive strength is the flexural strength and compressive strength.

Abstract Spirulina platensis was grown in SWlUe waste to reduce inorganic compowlds and simultaneously produce feed resources. Spirulina platensis prefers nitrogenous compounds in Ibe order: $NH_4^{+}-N>NO_3^{-}-N>simple-N$ such as urea and simple amino acids. It even consumes $NH_4^{+}-N$ first when urea or nitrate are present. Therefore, the content of residual $NH_4^{+}-N$ in Spimlina platensis cultures can be determined by the relative extent of the following processes: (i) algal uptake and assimilation; (ii) ammonia stripping; and (iii) decomposition of urea to NH;-N by urease-positive bacteria. The removal rates of total nitrogen ffild total phosphorus were estimated as an indicator of the treatment effIciency. It was found that Spirulina platensis was able to reduce 70-93% of $P_4^{3-}-P$, 67-93% of inorganic nitrogen, 80-90% of COD, and 37-56% of organic nitrogen in various concentrations of swine waste over 12 days of batch cultivation. The removal of inorganic compounds from swine waste was mainly used for cell growth, however, the organic nitrogen removal was not related to cell growlb. A maximum cell density of 1.52 dry-g/l was maintained with a dilution rate of 0.2l/day in continuous cultivation by adding 30% swine waste. The nitrogen and phosphorus removal rates were correlated to the dilution rates. Based on the amino acid profile, the quality of the proteins in the Spirulina platensis grown in the waste was the same as that in a clean culture.ulture.
