Chapter 21:  Solid and Hazardous Waste


Section 1:  What are Solid Waste and Hazardous Waste, and Why are They Problems?

​Concept 21-1A:  Solid waste contributes to pollution and includes valuable resources that could be reused or recycled.

​Concept 21-1B:  Hazardous waste contributes to pollution, as well as to natural capital degradation, health problems, and premature deaths.


Section 2:  How Should We Deal with Solid Waste?

Concept 21-2:
 A sustainable approach to solid waste is first to reduce it, then to reuse or recycle it, and finally to safely dispose of what is left.


Section 3:  Why are Refusing, Reducing, Reusing, and Recycling So Important?

Concept 21-3:
 By refusing and reducing resource use and by reusing and recycling what we use, we decrease our consumption of matter and energy resources, reduce pollution and natural capital degradation, and save money.

Section 4:  What are the Advantages and Disadvantages of Burning or Burying Solid Waste?

Concept 21-4:
 Technologies for burning and burying solid wastes are well developed, but burning contributes to air and water pollution and greenhouse gas emissions, and buried wastes eventually contribute to the pollution and degradation of land and water resources.


Section 5:  How Should We Deal with Hazardous Waste?

Concept 21-5:
 A more sustainable approach to hazardous waste is first to produce less of it, then to reuse or recycle it, then to convert it to less-hazardous materials, and finally to safely store what is left.


Section 6:  How Can We Make the Transition to a More Sustainable Low-Waste Society?

Concept 21-6:
 Shifting to a low-waste society requires individual and businesses to reduce resource use and to reuse and recycle wastes at local, national, and global levels.
