The modification of calcium sulfite in semi-dry desulfurization ash was studied. By the combining use of catalyst and oxidant, the content of calcium sulfite in the modified desulfurized ash was greatly reduced. In this way, the calcium oxide and calcium sulfate in the modified desulfurization ash were used to partially replace the lime, gypsum and other materials in the process of autoclaved brick production. The hydration reaction mechanism was discussed. Introduction It is common knowledge that sulfur dioxide is a main cause of acid rain.

...Abstract The aim of the Project is to find out the geo-engineering properties of fly ash, which can act as a stabilizer to many soils in geo-engineering field. The project describes the use of local fly ash in construction industry in a way to minimize the industrial waste. Their been serious shortage of natural material, which are used in Highway or Earth dam construction. Due to soil excavation, deforestation occurs which affects the bio-diversity. Industrial waste such as fly-ash, slag etc can be effectively used in soil stabilization. Several geo engineering Labrotory experiments were performed on fly ash to determine its properties, which may be used in road construction, earth dam construction, soil stabilization etc. If these materials can be used in highway or dam construction, it will be a great effort in minimizing the industrial pollution. Fly ash was collected from captive power plant from the dump pad of Rourkela steel plant. These are stored in air tight container after being oven-dried. Experiments such as determination of compaction properties, CBR analysis, Un-confined compressive strength test, permeability etc are done in order to determine the geo-engineering properties of fly ash, which can taken account in the construction field. A brief comparison is made between fly ash and other soil properties which are used as sub-grade, base in Highway construction. Introduction Electricity is the key for development of any country.

...pid=S1516-14392008000200008&script=sci_arttext Process parameter optimization for fly ash brick by Taguchi method Prabir Kumar Chaulia*; Reeta Das Central Mechanical Engineering Research Institute, Durgapur–713209, India ABSTRACT This paper presents the results of an experimental investigation carried out to optimize the mix proportions of the fly ash brick by Taguchi method of parameter design. The experiments have been designed using an L9 orthogonal array with four factors and three levels each. Small quantity of cement has been mixed as binding materials. Both cement and the fly ash used are indicated as binding material and water binder ratio has been considered as one of the control factors. So the effects of water/binder ratio, fly ash, coarse sand, and stone dust on the performance characteristic are analyzed using signal–to–noise ratios and mean response data. According to the results, water/binder ratio and stone dust play the significant role on the compressive strength of the brick. Furthermore, the estimated optimum values of the process parameters are corresponding to water/binder ratio of 0.4, fly ash of 39%, coarse sand of 24%, and stone dust of 30%. The mean value of optimal strength is predicted as 166.22 kg.cm–2 with a tolerance of ± 10.97 kg.cm–2. Confirmatory experimental result obtained for the optimum conditions is 160.17 kg.cm–2.

...1. ABSTRACT Alternative uses of waste for energy production becomes increasingly interesting both from a waste management perspective - to deal with increasing waste amounts while reducing the amount of waste deposited at landfills and from an energy system perspective to improve the flexibility of the energy system in order to increase the share of renewable energy and reduce greenhouse gas emissions. The object of analysis is waste which is not reused or recycled, but can be used for energy production. Different Waste-to-Energy technologies are analyzed through energy system analysis of the current Danish energy system with 13-14% renewable energy, as well as possible future Danish energy systems with 43% (2025) and 100% renewable energy (2050), respectively. The technologies include combustion, thermal gasification, anaerobic digestion, fermentation, and transesterification technologies producing electricity, heat, or transport fuel. In the USA, according to the US energy recovery council, there are 87 WTE plants producing 2,700 megawatts that results into 17 million of kwh per year which is enough to meet the needs for power for 2 million households. In the EU incineration is more popular. According to the confederation of European Waste to energy plants (CEWEP) the plants in Europe can supply annually about 13 million inhabitants with electricity and 12 million inhabitants with heat. Waste to energy is produced mainly by biological material and thus the energy produced...

We will view the causes and effects of some of our waste effects on our landscape that we live in. We will view some prevention methods offered by communities, cities, and schools. States and government agencies almost always use cost as a scape goat in the protection of our environment. Our environment needs the protection of us all and we need to come together to combat this problem as a nation and eventually as a world effort or we will not have a world to protect. We can control ground pollution with proper prevention methods because of education of standards for soil contamination and ground water contamination. The first topic we should discuss is Soil Contamination. We take for granted our environment and it has such a fragile ecosystem. Most of our Resources and food sources come from the ground and are contributing to the pollution on and in the ground. “Soil pollution is a result of many activities and experiments done by mankind which end up contaminating the soil.” (Ujwal Deshmukh) Through the mining of some of our resources we end up with solid material waste. Tens of thousands of unreclaimed hard rock mining sites, abandoned generations ago, litter the landscape. Many of those sites constitute sources of substantial...
