This session will focus on the approaches, policies, and practices that can promote sustainable waste management and resource recovery. We will be guided by the following questions.
Waste is unwanted material intentionally thrown away for disposal.
- What are the basic characteristics of waste as it relates to urban waste management issues?
- Solid vs liquid
- Organic vs inorganic
- Human activities
- Agriculture, husbandry
- Energy sources
- Water collection and use
- Building shelters and buildings
- Making tools and other objects for cultural, industrial and spiritual reasons
- Conflict and warfare
- Production of products with toxic materials
- What waste management systems and technologies have been developed by planners in the “industrialized world”?
- Landfills
- Recycling
- Composting
- What are the environmental and social impacts of these waste management systems and technologies?
- The waste stream has become much more toxic
- Accumulation of toxics in the waste stream
- Toxins like dioxin are now in the breast milk of every woman on earth.
- Accumulation of inorganic material in the waste stream
- What alternative systems and technologies can be put into place?
- We have to move from a waste management approach to a resource recovery approach. (“Because approach is the highest level”)
- Composting: 40% of the waste in landfills is food waste
- Ashes
- Cans and bottles
- Electronics recycling
- Thrift stores
- Cradle to grave vs cradle to cradle
- RRRR: Reduce, reuse, recycle, rot
- Up-cycling, down-cycling
- We have to move from a waste management approach to a resource recovery approach. (“Because approach is the highest level”)
- How viable are these alternatives?
- These alternatives are extremely viable
- They are used throughout Europe
- How can waste management professionals promote sustainable waste management and use?

- Resource economy is a linear process with many open loops, therefore not sustainable.
- 1/3 of our initial natural resources are now gone.
- Less than 4% of natural forests remain in the US.
- 5% of the word’s population lives in the US
- US uses 30% of the world’s resources
- US creates 30% of the world’s waste
- 80% of the planets forests are now gone
- 75% of fisheries are fished over their capacity
-
- Planned obsolescence: products designed to fail so you have to buy a new one
- National happiness is going down while consumption is going up
- We have less leisure time than at any point since feudal society
-
- Reduces waste and reduces inputs
- Much of the garbage can’t be recycled because it’s toxic or it’s designed to be impossible to recycle (ie tetra-packs)
- One can of trash in front of your house means 71 cans of trash upstream in order to make the stuff in your one can of trash
