Introduction

"Hope is a good breakfast, but it is a bad supper." Sir Francis Bacon

Green technology is the environment friendly way to protect the Earth’s natural resources and the environment we inhabit.

Its application of knowledge to reduce impact of human activities on the environment.

By natural resources we mean surface water, Atmosphere, Coasts, Land etc.

Protection of environment we mean to protect all these natural resources from contamination , pollutants and toxic chemicals.

Types of Environmental TechnologyRecyclingRenewable EnergyWater PurificationAir PurificationSewage Treatment Solid Waste ManagementEnergy Conservation

RecyclingRecycling is processing used materials

(waste) into new products to prevent waste of potentially useful materials.

Recycling means making waste or already used things into brand new products.

Renewable EnergyRenewable Energy is energy which comes from

natural resources.About 16% of global energy is from renewable

resources.By renewable energy we mean wind energy, solar energy , biomass , hydro

power energy.

Water PurificationWater purification is the process of removing

undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water.

Simply it is the process of removing contaminants from raw water source.

Most water is purified for human consumption (drinking water).

According to a 2007 (WHO) report, 1.1 billion people lack access to an improved drinking water supply.

Air PurificationAir can be purified by growing common

plants because they convert Carbon Dioxide into Oxygen.

For example: Neem tree ,Palm tree, Tulsi tree ,Eucalyptus etc

Sewage TreatmentIt is similar to water purification It is the process of removing contaminants

from wastewater and household sewage.Its objective is to produce environmentally

safe fluid suitable for safe disposal or reuse.

Solid Waste ManagementSolid waste management is the recycling,

reuse, disposal and treatment of solid waste.process is generally undertaken to reduce

their effect on health, the environment or aesthetics.

Types of solid waste management:• Landfill• Incineration• Recycling

Energy ConservationIt refers to the efforts made to reduce energy

consumption.Energy conservation is carried out by using

the devices that consume smaller amount of energy in order to reduce the consumption of energy.

Reducing the use of electricity causes less fossil fuels to be burned to provide that electricity.

Goals of Green TechnologySustainabilityCreating products that can be fully reclaimed

or re-used.Reducing waste and pollution by changing the

patterns of production and consumption. Developing alternatives to technologies -

whether its fossil fuel or chemical intensive agriculture - that have been demonstrated to damage health and the environment.

Creating a center of economic activity around technologies and products that benefit the environment
