Methodology
During 2003 and 2004 over 9,000 questionnaires were sent to households in Cardiff exploring all aspects of waste management behaviours and attitudes; an overall response rate of 30% was achieved.
To supplement and explore trends identified in the survey nearly 40 semi-structured interviews were conducted with Cardiff residents. These were randonly chosen from those who returned the questionnaire. In addition, interviews took place with interested individuals and stakeholders, such as regional and national government officials and civil society groups, in order to determine the spectrum of opinions on all aspects of household waste management policy and behaviour.
