This lesson contains significant amount of information on existing and developing methods of resource conservation and waste treatment. This information is mainly related to dealing with municipal waste and does not cover special types of waste such as nuclear or agricultural waste. Wastewater and sewage treatment is a separate topic that will be addressed in the next lesson. The general thought that summarizes this lesson is that treatment of waste is dirty and expensive business - it is better to prevent it than clean it up. New technologies that would change the situation to a more sustainable world must involve transformative design innovations that increase the recyclability and biodegradability of the waste stream outputs. Life cycle thinking and modeling will help to identify the best scenarios for sustainable actions.

1. Search the web for innovative ideas aimed at efficient waste disposal or removal. 2. Post the link to the story or source. 3. Briefly explain the principle of technology or approach. 4. Express your own opinion on the promise of this idea.
This search can be related to any scale of waste disposal or cleanup (from industrial to small household or community wide). Let us stick to the solid waste area (wastewater treatment is a separate topic). It can be both a technological system or simply a strategy, but it should provide a way to make our living environment cleaner.
