Well-organised waste management is an essential part of sustainable development. The saving of resources and energy is everyone's concern and environmental education is vital to guarantee a sustainable lifestyle in the long run. To find out what similarities and differences in views regarding waste management exist between grammar school pupils and comprehensive school pupils in England, questionnaires were designed and distributed in two schools in the same English city. The questionnaires aimed at quantifying and establishing students' knowledge, attitudes and behaviour regarding waste management. The results illustrate that students from the grammar school had higher levels of knowledge, were more likely to recycle and used more sources of information regarding waste management. Waste reduction was considered important by almost all students. However, students in both schools considered composting and waste reduction as less important than recycling and thereby did not fully agree with sustainable waste management.
