The need of Electricity is growing fast because of population and Industrial demand and its advantages and uses
The need of Electricity is growing fast because of population and Industrial demand and its advantages and uses. Fly ash is a by-product of power generation with coal. As per the present India statistics, Coal based power generation holds about 72% of India’s power generation capacity. There are around 151 thermal power plant. They are Generating about 176.744 Million-Ton. In future, thermal generation capacity in India will increase significantly in the coming decades. Ash disposal can have adverse impacts on the environment due to land use diversion, resettlement, water resources allocation and air pollution. Construction of large ash disposal areas results in resettlement issues, loss of agriculture/grazing land/ habitat. When the ash gets dried in the absence of water or vegetation cover, fugitive dust from ash pond pollutes the air thereby increasing local concentration of respirable particulate. Once-through slurry disposal systems place additional strain on scarce fresh water resources. Stone quarrying causes a significant impact on the environment. In particular, it is often necessary to blast rocks with explosives in order to extract material for processing but this method of extraction gives rise to including noise pollution, air pollution, damage to biodiversity and habitat destruction. Air Pollution Dust from quarry sites is a major source of air pollution, although the severity will depend on factors like the local microclimate conditions, the concentration of dust particles in the ambient air, the size of the dust particles and their chemistry, for example limestone quarries produce highly alkaline (and reactive) dusts, whereas coal mines produce acidic dust. Damage to Biodiversity One of the biggest negative impacts of quarrying on the environment is the damage to biodiversity. Biodiversity essentially refers to the range of living species, including fish, insects, invertebrates, reptiles, birds, mammals, plants, fungi and even micro-organisms. Biodiversity conservation is important as all species are interlinked, even if this is not immediately visible or even known, and our survival depends on this fine balance that exists within nature. Quarry Waste Again, like many other man-made activities, quarrying involves the production of significant amounts of waste. Some types of quarries do not produce large amounts of permanent waste, such as sand and gravel quarries, whereas others will produce significant amounts of waste material such as clay and silt. The good news is that they are generally inert and non-hazardous, unlike the waste from many other processes. However, there is still potential for damage to the environment, particularly with water contamination. Our Project mainly concern in reducing Environmental effect and Utilisation of by-product Material like Fly Ash by making artificial aggregate with the help of geopolymerisation. Geopolymerisation is a geosynthesis, a reaction that chemically integrates minerals. The exposure of Aluminosilicate materials such as FLY ASH, GGBS, or thermally activated substances to high-alkaline environments (hydroxides, silicates) gives rise to the formation of a geopolymer. Geopolymers are characterized by a two- to three-dimensional Si-O-Al structure.
