Depletion of Ozone layer

Effects of mining, drilling, etc

Toxics

Slide 21

Energy

Green Chemistry will be essential in

developing the alternatives for energy generation (photovoltaics, hydrogen, fuel cells, biobased fuels, etc.) as well as

continue the path toward energy efficiency with catalysis and product design at the forefront.

Slide 22

Global Change

Concerns for climate change, oceanic temperature, stratospheric chemistry and global distillation can be addressed through the development and implementation of green chemistry technologies.

Slide 23

Resource Depletion

Due to the over utilization of non-renewable resources, natural resources are being depleted at an unsustainable rate.

Fossil fuels are a central issue.

Slide 24

Resource Depletion

Renewable resources can be made increasingly viable technologically and economically through green chemistry.

Biomass

Nanoscience & technology

Solar

Carbon dioxide

Chitin

Waste utilization

Slide 25

Food Supply

While current food levels are sufficient, distribution is inadequate

Agricultural methods are unsustainable

Future food production intensity is needed.

Green chemistry can address many food supply issues

Slide 26

Food Supply

Green chemistry is developing:

Pesticides which only affect target organisms and degrade to innocuous by-products.

Fertilizers and fertilizer adjuvants that are designed to minimize usage while maximizing effectiveness.

Methods of using agricultural wastes for beneficial and profitable uses.

Slide 27

Toxics in the Environment

Substances that are toxic to humans, the biosphere and all that sustains it, are currently still being released at a cost of life, health and sustainability.

One of green chemistry’s greatest strengths is the ability to design for reduced hazard.

Slide 29

Conclusion

Green chemistry Not a solution to all environmental problems But the most fundamental approach to preventing pollution.
