Solid waste curricula from various programs around the country were reviewed using eight variables identified as predictors of conservation behavior. Scores demonstrated that solid waste curricula focus mainly on knowledge and include, to a lesser extent, attitude change and action strategies. Lists the 14 programs evaluated in the study. (MDH)

Describes a project in which students developed an all-class laboratory activity called "The Decomposition of Organic and Inorganic Substances in a Landfill". Explores what conditions are necessary to facilitate decomposition in a landfill. (SAH)

Describes current research and development aimed at producing techniques for conversion of organic wastes to fuel, although these sources can only provide less than 10

Educators and educational institutions are frequently called upon to address issues when behavioral changes are needed. Solid waste is no exception.
