Deeper Insights into role of Green Technology for Pollution Free Environment: An updated Review

Abstract

India is the second largest country in the world based on the population that faces many challenges for various environmental issues such as water and air pollution etc. As per the survey by World Bank experts this issues become more exacerbated between 1947 and 1995. Within last decade India has devoted towards putting much efforts to resolve these environmental issues and improving environmental qualities. The major possible issues those contributes to various environmental issues include population growth, deforestation, establishment of industries for growth of economy, burning of fuel, degradation of agricultural lands, drainage of consumer waste into water resources such as rivers, depletion of natural resources such as water, mineral, rocks etc. Another major factor that contributes largely for environmental pollution includes solid waste pollution. As per the data available elsewhere there are more than hundred million tons of solid wastes generated by various cities in India in every year. Now-a-days it has been observed that the tourist places of India are also facing such issues. Green technology is an environment friendly technology which has developed and used to protect the environment and conserves natural resources. This technology is intended to mitigate or reverse the effects of human activity on the environment. Green technology generally uses innovative ideas and methods to create environment friendly products. Green nano-technology that uses green engineering and green chemistry is one of the emerging fields in science and technology. In the matter of environmental pollution and the disposal of waste, Green technology answers to that as well. Among all the possible areas where the creations and growth are possible that include; eco- friendly textiles, biodegradable papers and containers, green energy, green building, organic agriculture, and manufacturing of similar products and materials to support green business. Green technology covers a broad area of production and consumption technologies. The 7R’s of green technology also includes replace, reduce, reliable, repair, reuse, recycle and resources. The green technologies involve the use of environmental technologies for assessment of pollution prevention and control, remediation and restoration. A prevention technology helps to avoid the production of environmentally hazardous substances to minimize damage to the environment.
