The efficiency and problem of SNCR in cement are explained by case study .Catalyst also is discussed by the research. And this paper presents and discusses the technical feasibility issues related to implementing SCR technology at cement plant. Some pilot plant trial and scale-full plant are also discussed and the result show that SCR can reduce NOx emissions from cement kilns by greater than 90% and achieve less than 100 mg/Nm3 NOx emissions. The fact suggests that it is a more effective and proven technology to reduce nitrogen oxide emissions from cement kilns.

The aim of this work is to verify the technical feasibility of composting in the case of Marrakech prefecture. On the basis of waste composition and in accordance with the choice of the installation of Marrakech controlled landfill, composting has been considered as the most suitable waste treatment. To ensure the feasibility of composting, physicochemical analyses have been carried out on the fermentable part of waste; analyses on the content of metal elements have also been performed on the fine fraction, since the most important part is located in the same fraction. All parameters determined in the laboratory, have shown that optimal conditions to have good quality compost have been respected. The only restriction identified is the copper content, which should be less than 20 ppm. Generally the low levels of metal element content indicate that the storage and collection conditions of waste have not influenced their quality. On the other hand, the process must be properly controlled and managed, to produce high-quality compost.

This research is an example of designing City Green Open Space (RTH) by considering community opinion in the process and encouraging the growth of participation from the community itself as the ultimate goal. As a case study, Pasir Impun post-operation landfill (TPA) in Bandung City was taken. With the aim of increasing the area of RTH, in Bandung Strategic Plan 2004-2009, one of the planned programs was to re-arrange the Post-Operation Landfill, Pasir Impun, in the East Bandung. In terms of technical feasibility, Pasir Impun post-operation landfill is considered the most ready to be converted, Whereas from a social standpoint, this landfill is surrounded by fairly dense residential areas (1,254 inhabitants), who do not have public open spaces that can be used by the community for recreation or other social activities, so that the Pasir Impun post-operation landfill with an area of ± 4.1 Ha is considered to have great potential to be developed as an local Green Open Space. It is expected that with this approach, the results of the design of Green Open Space on the Post-Operation Landfill Pasir Impun, can answer the basic needs of the community and in the end can guarantee the success of land conversion and the program sustainability. The design process begins by conducting a survey directly to the land and surrounding settlements, interviews with relevant parties, distributing questionnaires to the community, as well as literature and precedents. Furthermore, an analysis of these activities is carried out to compile and formulate a space program and design criteria as the basis for the design that will be created or developed. The final result of this design process is a design simulation of local open space on the Pasir Impun post-operation landfill.
