TOPIC-ASSIGNMENT ON “ENVIRONMENTALLY SOUND TECHNOLOGY”

INTRODUCTION

ENVIRONMENTALLY SOUND TECHNOLOGIES(ESTS) ARE ANY TECHNOLOGY THAT EITHER DIRECTLY OR INDIRECTLY IMPROVES THE ENVIRONMENT.

DEFINITION

DEFINITION OF ESTS IS BASED ON AGENDA 21 .CHAPTER 34 OF AGENDA 21 DEFINES ESTs AS

->PROTECT THE ENVIRONMENT->ARE LESS POLLUTING ->USE ALL RESOURCES IN A SUSTAINABLE MANNER->RECYCLE MORE OF THEIR WASTES AND PRODUCTS->HANDLE RESIDUAL WASTES IN A MORE ACCEPTABLE MANNER THAN THE TECHNOLOGIES FOR WHICH THEY ARE SUBSTITUTES

->APPLIES TO THE TRANSITION OF ALL TECHNOLOGIES IN BECOMING MORE ENVIRONMENTALLY SOUND.

->CAPTURES THE FULL LIFE CYCLE FLOW OF THE MATERIAL,ENERGY AND WATER IN THE PRODUCTION AND CONSUMPTION SYSTEM.

->THE GOAL IS TO PRODUCE ZERO WASTE .

->CONSIDERS TECHNOLOGY DEVELOPMENT IN BOTH THE ECOLOGICAL AND SOCIAL CONTEXT.

NOT SOCIALISTIC SOUND PEOPLE ARE FOUND

EST PERFORMANCE

=> CAN BE ECONOMICALLY ATTRACTIVE DUE TO REDUCED COSTS OF INPUT MATERIALS,ENERGY AND WATER.=>INCREASED PRODUCTION AND BETTER OUTPUT QUALITY.=>ADDITIONAL ENVIRONMENTAL BENEFIT ARISING FROM THE CONSERVATION OF NATURAL CAPITAL.=>NEED OF MORE NEW STRATEGIES AND APPROACHES TO CREATE GREATER AWARENESS AND ACCEPTANCE OF EST.

WORLD VIEW AND INDIAN VIEW

=>ESTS ARE MORE IN USE IN ALL OVER THE WORLD.ECONOMICALLY IT IS HELPING THEM A LOT AND SO FOR THAT THEY ARE FINDING THE WAY TO SAVE THE NATURAL RESOURCES IN A VARIETY OF MEANS.

=>IN INDIA THOUGH ESTS ARE IN USE IN SOME PART OF OUR COUNTRY. BUT STILL THEY ARE LACKING IN THE USE OF IT IN FULL NATIONAL LEVEL.OBVIOUSLY A LIST OF PROBLEMS ARE THERE BUT THE MAIN PROBLEM IS IN OUR ECONOMIC LEVEL.

SO WHERE DO WE COME?

IS IT POSSIBLE?

OBVIOUSLY YES IF WE GO WITH THE MOTTO OF GO GREEN

THANKING YOU
