Waste to Resources

Waste of all kinds has the potential to affect the environment and our natural resources. From the water we drink to the land we live on, our decisions about how to manage waste impact our communities and the world around us. How can we make responsible choices about our waste? How can we manage our growth in a way that is sustainable? How can we turn our waste into resources?

Students will learn the concepts of different waste streams and the impacts of waste generation and disposal on natural resources and society. Students will also learn effective ways to manage waste regeneratively; as well as the social, economic, and political impacts of turning waste products and degraded lands into resources.
