1. Green Chemistry Principles in Supporting
Environmental Conservation Efforts
By Ari Christian

2. Learning objectives
After studying this chapter, it is hoped that you will be able to:
1. Analyze the principles of green chemistry in daily life
carefully.

3. How is the principle of
applying green chemistry?
Have the principles of green
chemistry been applied in your
home?

4. 01

03
What chemicals are used in your home?
Let's Discuss
Together with friends, discuss the following questions!
How do you use these materials?
Has the use of chemicals in your home contributed to the application of
green chemistry?

5. Using enough chemicals, disposing of
chemicals in the right place, storing chemicals in
the right way, replacing harmful chemicals with
natural materials that are environmentally
friendly, and reusing plastic materials are forms
of your contribution to the application of green
chemistry.

6. Chemical hazards referred to in the green
chemistry concept include various threats to human
health and the environment, including toxicity,
physical hazards, global climate change, and the
depletion of natural resources.

7. Green chemistry is a very effective approach to
prevent pollution.
Research areas in the field of green chemistry
include developing more environmentally
friendly synthesis methods, using renewable raw
materials, designing green chemicals, and using
biotechnology as an alternative in industry.
The following are the twelve principles of green
chemistry proposed by Anastas and Warner.

8. Prevent the generation of waste in
the synthesis process
01

9. Designing safe chemical products
02
The trick is to replace the functional group or by lowering the
bioavailability value.

10. Design a safe synthesis process
03
This can be done in two ways, namely minimizing exposure or
minimizing harm to people who use these chemicals.

11. Using renewable raw materials
04
Renewable raw materials usually come from agricultural products
or natural products, while non-renewable raw materials come
from fossil fuels, such as petroleum, natural gas, coal, and other
mining materials.

12. Using a catalyst
05
In terms of green chemistry, the use of catalysts plays a role in
increasing selectivity, being able to reduce the use of reagents,
and being able to minimize the use of energy in a reaction.

13. Avoid derivatization and temporary
modification in chemical reactions
06
Unnecessary derivatization and modification must be
minimized because each step of derivatization requires
additional reagents which will increase the amount of waste.

14. Maximizing atom economy
07
Atom economy is used here to assess the proportion of
products produced compared to the reactants used. If all the
reactants can be completely converted into products it can be
said that the reaction has an atomic economic value of 100%.

15. Using safe solvents
08
Excessive use of solvents will result in pollution that will
pollute the environment. Another alternative is to use several
types of solvents that are more environmentally friendly, such
as ionic liquids, fluorous phase chemistry, supercritical carbon
dioxide, and "biosolvents".

16. Increase energy efficiency in reactions
09
The use of alternative and efficient energy in synthesis can be
done using several new methods, including using microwave
radiation, ultrasonics, and photochemistry.

17. Designing biodegradable chemicals
10
Chemicals must be easily degraded and not accumulate in the
environment. Such as the synthesis of biodegradable plastics,
bioderadable polymers, and other chemicals.

18. Use of direct analytical methods to reduce
pollution
11
The analytical method carried out in real-time can reduce the
formation of unwanted by-products.

19. Minimizing Accident Potential
12
Chemicals used in chemical reactions must be selected in such
a way that the potential for accidents that may result in
chemical entry into the environment, explosion and fire is
avoided.
