This paper has been prepared in response to a request of the Conference of the Parties at its twenty-first session. It is based on a review of the expert literature on the subject, as well as on the presentations and discussions that took place during the technical expert meetings held in 2018 under the technical examination process on mitigation.

The information is structured with the help of the questions from the Talanoa Dialogue, with a focus on waste-to-energy technologies and on supply chain redesign and industrial waste reuse and prevention solutions. Both solutions are essential for the transition to a circular economy.
