7. Introduction to waste treatment
WHAT DO YOU THINK ABOUT THESE QUESTIONS:
What are waste?
What are the source of waste?
Why waste treatment is critical?
What are the link between waste, waste treatment and environment?
Who responsible for waste treatment?
What are options prior waste treatment?

8. What do you think and why?
What are waste?
WASTE is UNUSED and DISPOSED PRODUCTS (i.e. trash, rubish, garbage, etc.) OR
WASTE is POTENTIAL RESOURCES
What do you think and why?

9. What are waste? Previously (Long time ago) But TODAY
Waste (also known as rubbish, trash, refuse, garbage, junk, litter, and ort) is unwanted or useless materials.
But TODAY
WASTE IS EQUAL WITH ECONOMIC or
Why do you think that NOW there is a different perseption on valuing waste?

10. What are the source waste?
Households
Commerce and Industry

11. What are the source waste?
Agriculture (farming)
Forestry
Transportation
Demolition
etc

12. Why waste treatment is critical?
After industrial revolution, waste becomes major concern to be resolved
Too much untreated waste disposed directly to environment  harmful effect to human and environment
Too many industries have no proper waste treatment mean DANGEROUS  HIGHLY TOXIC or HIGHLY ORGANIC WASTE goes to the environment
Waste treatment is critically needed to reduce waste being disposed to the environment or being exposed to human

13. What are the link between waste, waste treatment and environment?
High amount of waste, if untreated, is harmfull to the environment
Waste treatment is needed to reduce the amount of waste or to ensure that waste are safe for disposal to environment
With appropriate and proper waste treatment, pollution to the environment can be avoided
Safe and healthy environment can be achieved for better living

14. Who responsible for waste treatment?
Individual
Community
Farmers
Industries
Governments
Why those representative are responsible??? What do you think?

15. What are options prior waste treatment?
Waste treatment hierarchy

16. WASTE TECHNOLOGY Mainly divided into several types: Pre-treatment
Physical
Chemical
Biological
Thermal
Combination waste treatment (i.e. thermo-chemical, etc.)

17. WASTE TECHNOLOGY Or in wastewater treatment can also be classified as:
Pre-liminary treatment
Primary treatment
Secondary treatment
Tertiary treatment

18. Waste treatment technology selection
Selection of technology for waste treatment is critical
It represent the effectivity and efficiency of the process
Technology can be selected depend on the characteristic of the treated waste (i.e. organic waste vs toxic waste, or vs anorganic waste
Thus, characterisation of waste are crucial
