4. What is nature conservation?
• The wise management and utilization of natural renewable
resources in a sustainable manner
• Ensures the maintenance of biodiversity
Role of an Engineer
 To develop solutions to environmental
problems using the principles of
- engineering
- biology
- chemistry
4

5. Threats to Nature Conservation
• Water pollution
• Severe climate changes
• Land corrosion
• Waste disposal
• Deforestation
• Ozone layer depletion
• Pollution 5

6. Environmental Engineers
Apply scientific and engineering principles to conserve the environment.
• Acid rains
• Global warming
• Ozone depletion
• Water/Air pollution
• Industrial sources
They address local and environmental issues

7. Objectives of Environmental Engineering
 Find solutions to environmental issues like,
 Energy preservation
 Protection of assets
 Controlling of waste from human and animal activities

9. Civil Engineer
• Develops integrated strategies to ensure that the movement of
people and goods is efficient
• Develops strategies for
- resilient power supply
- management of water resources
- treating waste as a resource

11. MeasuresTaken by Civil Engineers
• Waste from demolition of buildings and structures
• Eliminate
• Reduce
• Reuse
• Recover
• Dispose
• Use of sustainable building materials
• Reducing energy consumption and emission of greenhouse gases
11

12. What is Green Engineering?
• Production of energy and materials from “green feed-stocks”.
• Green feed-stocks
• bio mass
• microorganisms
12

13. This can be done by
• Identifying and evaluating options and resources usefully
• Making significant and invaluable improvements
Green engineering check list for a chemical engineer
 New plant considerations
 Assess existing facilities

14. Conclusion
• Engineers do have their share in the destruction of the environment
• Nature conservation is an extra cost for an industry
14

15. Conclusion
• Engineers are searching for more and more methods to conserve nature
• To make a difference everybody should understand the value of nature and its
current state
• Let’s make a conscious effort to conserve the nature
