This Webinar is organized by the Swedish University of Agricultural Sciences (SLU), Makerere University and the Research Institutes of Sweden (RISE) in collaboration with SuSanA working group 5 as part of the SPANS research project. It will present a new publication related to resource recovery from sanitation systems – the Guide to Sanitation Resource-Recovery Products & Technologies. The publication is designed as a supplement to the Eawag Compendium of Sanitation Systems and Technologies. It provides an overview of the possibilities for resource recovery from sanitation and provide guidance on treatment processes to achieve safe products for reuse. The webinar will introduce the guide, including an overview of the technologies and products that are covered in the document, and discuss how the information sheets can be used a reference book for sanitation planning and decision-making.
The world is currently undergoing a paradigm shift towards a circular society in which resources are recovered and reused rather than discarded. Sanitation systems manage carbon, nutrient and water flows that are key resources that should be recovered and recirculate instead of being released into the environment. Increasing resource recovery within our sanitation systems can play a critical role in shifting to a more sustainable society.
Resource-recovery sanitation systems are defined as systems that safely recycle excreta and organic waste while minimizing the use of non-renewable resources, such as water and chemicals. Safe recycling means that waste flows are managed so that physical, microbial and chemical risks are minimized. Thus, the recycled product should not pose any significant health threat or environmental impact when correctly used.
There are a growing number of sanitation treatment technologies that are designed to recover reusable products. Many of these technologies are innovative and markets for them are still emerging. The aim of this publication is to gather up-to-date information regarding resource recovery technologies into a single document for easy access. The hope is that this document will be a living document that will continue to evolve as the technologies develop.
The specific objectives of this webinar are:
1. To expose participants to a broad range of recovered sanitation products and innovative treatment technologies.
2. To provide an overview of the technology information sheets for resource recovery and what information they provide.
3. To discuss opportunities for integrating resource-recovery technologies into planning & decision-making processes
