  • Conserving, ProtectingGreen and Renewing the EnvironmentTechnology Bhavya Jain(128) CSE – B (2012 – 2016)
  • What is Green Technology? Environmental technology (envirotech), green technology (greentech) or clean technology (cleantech) is the application of one or more of environmental science, green chemistry, environmental monitoring and electronic devices to monitor, model and conserve the natural environment and resources, and to curb the negative impacts of human involvement. The term is also used to describe sustainable energy generation technologies such as photovoltaic, wind turbines, bioreactors, etc. Sustainable development is the core of environmental technologies. The term environmental technologies is also used to describe a class of electronic devices that can promote sustainable management of resources.
  • Environmental Objectives in 11thFive-Year Plan1. Increase forest & tree cover by 5%.2. Attain WHO standards of air quality in all major cities by 2011-2012.3. Treat all urban waste water by 2011-2012 to clean river waters.4. Increase energy efficiency by 20 percentage points by 2016-2017.Estimated Rs.15 crore has been spent for green technology inIndia in 2011.
  • Laws for Green TechnologyThe following picturehas been taken fromthe Indian ministry’swebsite which clearlypresents some of thelaws implemented forsupporting EnvironTech(Green Technology). Itstates that preservingthe environment is notan option but a chancefor sustenance.

  • GreenChemistry
  • Green ChemistryGreen chemistry, also calledsustainable chemistry, is aphilosophy of chemical researchand engineering thatencourages the design ofproducts and processes thatminimize the use and generationof hazardoussubstances. Whereas environmental chemistry is the chemistry ofthe natural environment, and ofpollutant chemicals in nature,green chemistry seeks to reduceand prevent pollution at itssource.
  • Green EnergyRenewable energy is energy thatcomes from resources which arecontinually replenished suchas sunlight, wind, rain, tides, waves andgeothermal heat. About 16% of globalfinal energy consumption comesfrom renewable resources, with 10% ofall energy from traditional biomass,mainly used for heating, and 3.4%from hydroelectricity. New renewables(small hydro, modern biomass, wind,solar, geothermal, and biofuels)accounted for another 3% and aregrowing very rapidly. The share ofrenewables in electricity generation isaround 19%, with 16% of electricitycoming from hydroelectricity and 3%from new renewables.
  • Green InformationTechnology
  • Green IT : TechnologyGreen IT stands for Green InformationTechnology. Information Technology isessentially the design, implementation andmanagement of computers that bothindividuals and businesses use.
  • Green Information Technology
  • Green BuildingGreen building (also knownas greenconstruction or sustainablebuilding) refers to a structure andusing process that isenvironmentally responsible andresource-efficient throughout abuildings life-cycle: from siting todesign, construction, operation,maintenance, renovation, anddemolition. This requires closecooperation of the design team,the architects, the engineers,and the client at all projectstages. The Green Buildingpractice expands andcomplements the classicalbuilding design concerns ofeconomy, utility, durability, andcomfort.
  • GreenNanotechnology
  • GreenNanotechnology Green Nanotechnology refers to the use of nanotechnology to enhance the environmental sustainability of processes currently producing negative externalities. It also refers to the use of the products of nanotechnology to enhance sustainability. It includes making green Nano-products and using Nano-products in support of sustainability.
  • GreenNanotechnologyDematerialization Nanoscale IronOne of the chief ways nanotechnology Nanoscale iron offers one safe approach formight decrease pollution is neutralizing chlorinated organic solvents,through dematerialization -- the organic chlorine-based pesticides like DDTreduction of materials required for and polychlorinated biphenyls (PCBs). Addmanufacturing. Products that can self- iron nanoparticles to tetrachloroethene (aassemble out of small components use common solvent used in dry cleaning) andmuch less material than ones we build the iron oxidizes, or rusts, freeing upfrom the top-down, which generate electrons. The reaction gobbles up thesewaste and often require solvents and electrons, leaving ethene, a naturallychemical processes. Meanwhile, occurring hydrocarbon.researchers are also developingingenious ways to monitor pollution, suchas nanosensors that can biochemicallydetect contamination and pathogens, inreal time and over large areas.
