The Waste Wise Schools Program was established by EcoRecycle Victoria to implement waste and litter education in Victorian schools. It is now operating in over 900 schools in Victoria and 300 schools in other Australian states / territories. This paper provides detailed case studies of two active schools in the Waste Wise Schools Program and considers for each school how the Program started, what it meant to the school, the environmental, educational, social and economic outcomes of the Program and the key success factors. It discusses evidence that the Program has changed the thinking and behaviour of many families at the schools, suggesting that the children may be acting as catalysts to influence their parent's waste wise behaviour, i.e. having an intergenerational influence. Guidelines for promoting this influence are proposed. (Contains 2 figures.)
