Introduction"Hope is a good breakfast, but it is abad supper."Sir Francis Bacon
Green technology is the environment friendly way toprotect the Earth’s natural resources and theenvironment we inhabit. Its application of knowledge to reduce impact ofhuman activities on the environment. By natural resources we mean surfacewater, Atmosphere, Coasts, Land etc. Protection of environment we mean to protect allthese natural resources from contamination, pollutants and toxic chemicals.
Types of Environmental Technology Recycling Renewable Energy Water Purification Air Purification Sewage Treatment Solid Waste Management Energy Conservation
Recycling Recycling is processing used materials (waste) intonew products to prevent waste of potentially usefulmaterials. Recycling means making waste or already used thingsinto brand new products.
Renewable Energy Renewable Energy is energy which comes from naturalresources. About 16% of global energy is from renewable resources. By renewable energy we meanwind energy, solar energy , biomass , hydro power energy.
Water Purification Water purification is the process of removingundesirable chemicals, biologicalcontaminants, suspended solids and gases fromcontaminated water. Simply it is the process of removing contaminantsfrom raw water source. Most water is purified for human consumption(drinking water). According to a 2007 (WHO) report, 1.1 billion peoplelack access to an improved drinking water supply.
Air Purification Air can be purified by growing common plantsbecause they convert Carbon Dioxide into Oxygen. For example: Neem tree ,Palm tree, Tulsi tree,Eucalyptus etc
Sewage Treatment It is similar to water purification It is the process of removing contaminants fromwastewater and household sewage. Its objective is to produce environmentally safe fluidsuitable for safe disposal or reuse.
Solid Waste Management Solid waste management is therecycling, reuse, disposal and treatment of solid waste. process is generally undertaken to reduce their effecton health, the environment or aesthetics. Types of solid waste management:• Landfill• Incineration• Recycling
Energy Conservation It refers to the efforts made to reduce energyconsumption. Energy conservation is carried out by using the devicesthat consume smaller amount of energy in order toreduce the consumption of energy. Reducing the use of electricity causes less fossil fuelsto be burned to provide that electricity.
Goals of Green Technology Sustainability Creating products that can be fully reclaimed or re-used. Reducing waste and pollution by changing thepatterns of production and consumption. Developing alternatives to technologies - whether itsfossil fuel or chemical intensive agriculture - that havebeen demonstrated to damage health and theenvironment. Creating a center of economic activity aroundtechnologies and products that benefit theenvironment
