Introduction
-
What is Environmental Engineering
- “Environmental engineering is the integration
of science and engineering principles to improve the
natural environment (air, water, and/or land resources), to
provide healthy water, air, and land for human habitation
(house or home) and for other organisms, and to
remediate pollution sites” – Wikipedia
- “Environmental engineering is manifest by sound
engineering thought and practice in the solution of
problem of environmental sanitation, notably in the
provision of safe, palatable, and ample public water
supplies; the proper disposal of or recycle of wastewater
and solid wastes; soil and atmospheric pollution, and the
social and environmental impact of these solutions.” –

Solid Waste Management and
Climate Change
• Description : First part of the module would
cover different aspects of solid and hazardous
waste management. Second part would focus on
the climate change and greenhouse gas
emissions, and how different technologies would
reduce the greenhouse gas emissions.
• Goal : To help students develop basic
understanding of solid and hazardous waste
management, and the climate change and its
possible causes.

White A4 Size Paper
• On top of the sheet, please write :
– Your Roll Number
– Your Name
– Your Home City
(We will also use your answer sheets for attendance  )

Marks for this Quiz do NOT count for grade
PHEW !!!
Thank God for
small mercies

Possible Responses
• You know it – then go ahead, answer it
• You do not know, but are tempted to guess – go ahead
and state it as (an intelligent) guess
• If even guessing it out of question,
just write INK (I do Not Know)
• Good news : The more INKs you have, the more
relevant this course for You 
• Others will figure out how much of their guessing was
adequately intelligent 
