Stakeholders, including Green Alliance which provided us with written evidence, are concerned that government has not given waste prevention and re-use sufficient priority.36 The Department told us that it aims to push waste up the ‘waste hierarchy’ over time. The waste hierarchy ranks waste management options according to what is best for the environment. Its priority is preventing waste in the first place, when waste is created it gives priority to preparing it for re-use, then recycling, then recovery for example incineration with energy recovery, and last of all disposal for example through landfill.37
