Problems with the study

Overestimation of yield

70-80% of glass collected in Sydney and Brisbane is crushed during collection and can’t be sorted for recycling

Overestimation of pollution impact/cost

Inclusion of upstream impacts

Pollution damage estimates overestimated - not adjusted for level of exposure / area

Underestimation of collection impact/double counting of production impact

Collection truck impact modelled using trip time rather than stop-start model

Health impact of diesel particulates needs to be reviewed

Pollution licences internalise costs – this was not considered

Study boundaries exclude related costs

Study ignores environmental impact of cleaning/preparation in the home and value of householder time taken to sort and store

Cost to companies – e.g. choice of recyclable materials for packaging, labelling etc.
