Background and objectives
Globally, there is increasing interest in recovering nutrients from excreta and excreta-derived waste streams, as a way to reduce reliance on chemical fertilizers and increase sustainability in agro-food systems. However, concerns about health risks associated with reuse of excreta-derived fertilizers, in all their forms, persist. The use of standards and certification systems can help address some of these challenges related to the quality of excreta-derived fertilizers and the health risks related to their use, but many colleagues in the sector do not have an overview of the standards and certifications that exist or recent developments in the area.
The objective of this webinar, therefore, is to provide an overview of work being done at different levels on the development and use of standards and certifications for excreta-derived fertilizers and nutrient products. Through a series of brief presentations and a panel discussion, the key challenges and opportunities for the use of standards and certification in nutrient reuse will be discussed, and participants in the webinar will also have an opportunity for knowledge exchange and networking with colleagues working on these issues.
