Task: Consider the following hierarchy of waste management technologies in decreasing order of preference:
1) Waste reduction
2) Reuse of material
3) Recycling
4) Treatment or incineration
5) Land disposal
What criteria do you think are the most important in this prioritization of preference? Do you think this order of preference is correct and if not what would you change?
Using specific examples to support your answers, what are advantages and disadvantages of each of the methods considering the options of on-site versus off-site waste management?
