Think you know your waste stream?  Or what’s been causing more contamination?  Strong interest in a December 2021 National ZW Conference session indicated a more in-depth webinar on these topics were warranted.  This webinar drills down into recent -shifts in waste characterization, and successful strategies for addressing contamination. 

Webinar description: -- An early step in planning for zero waste is having a good understanding about what items our communities are discarding in their waste bins—but how has this shifted during the pandemic? This session will share findings on pandemic waste trends, including key takeaways about the big shifts we’re seeing with regard to specific materials, such as plastics, organics, and paper items commonly discarded by residents and businesses.

… And with the fervent interest in cleaner materials that can be marketed successfully and used in the US and internationally, the second part of the webinar dives into the array of strategies being used to address contamination – and 1) what short and medium-term strategies are proving successful (and which are NOT), 2) what can and cannot beat economics, and 3) what options are likely to be effective in the bigger scheme of things.
