How much does switching to single stream affect my site’s recycle rate?
Summary: Urban building portfolio:
Started at an average 34% recycle rate Averaged 40% for next 8 months of data Increase of 6%!
Suburban building portfolio: Started at an average 26% recycle rate Averaged 27% for next 8 months of data Increase of 1%: NOT significantly higher
Conclusions
The majority of urban buildings in NE are recycling via single stream
After switching to single stream… Not every building will increase equally Percentages may change from month to month Suburban buildings may not increase at all
