CLM workshop presentations
Thank you for attending the WasteMINZ Conference 2025!
You can click on the links below to download the presentation slides from the CLM workshop. Please refer to the conference programme for more information about the schedule.
Please note, some presenters did not want their slides to be shared on the website.
We also ask you not to share this with anyone who did not attend the CLM workshop, as this is unfair to those that paid for the conference. We will be sharing the presentations with wider membership in six months.
If you have any questions, please reach out to the WasteMINZ team.
