There are many direct and indirect benefits of improved natural resource management in urban areas, benefits that may substantially contribute to human wellbeing. Unfortunately, most cities are missing out on these opportunities.
Instead, inadequate waste management, like open dumping of solid waste or poorly functioning sanitation, are common around the world. Wasteful resource management causes pollution and environmental degradation, affecting our health. It is also a missed economic opportunity: safe reuse of valuable nutrients and organic matter in waste streams can boost food production, generate renewable energy, and offer many business opportunities. Sustainable waste management can help to deliver on climate mitigation, reduce eutrophication as well as make cities more self-sufficient.
UrbanCircle will improve understanding of co-benefits and trade-offs between the flows of natural resources in cities, an area which has not received enough investigation, mainly due to complex cross-sectoral interdependencies. This process will include governance analysis and model development, drawing on empirical studies, co-designed with local stakeholders in Sweden, Colombia and Kenya.
The project work also involves piloting the Resource Value Mapping (REVAMP) tool. This tool enables cities to estimate their resource recovery potential basing on inputs of the quantities of organic waste streams they have, including wastewater and faecal sludge. Depending on local priorities, the tool also makes it possible to compare various resource recovery options on the basis of energy and nutrient outputs as well as potential revenues using a co-development process, as a novel platform for participatory planning and multi-actor engagement.
The outcomes will contribute to a more integrated urban policy making, facilitating identification of cross-sectoral synergies and trade-offs framed within the 2030 Agenda, contributing to the long-term sustainability of resources and the resilience of urban centres.
This paper presents a framework for assessing the societal impacts of increased circularity of resource recovery from organic waste streams at city scale.
In this book, SEI's Daniel Ddiba and other leading energy researchers share their views on challenges and solutions related to the energy system of the future.
A case study shows enabling factors and governance barriers critical to implementing circular economy strategies for organic waste in urban areas.
This research explores the importance of applying circular economy principles to the management of organic waste streams through resource recovery.
Explore your city or community's resource recovery potential of urban organic waste streams on the new web-based platform for SEI’s newly launched REVAMP tool.
How can the circular economy potential of urban waste streams in low- and middle-income countries be realized?
This paper identifies factors that facilitate or limit governance capacity for circularity in the form of resource recovery from urban organic waste streams.
This inventory report is a first step towards creating scenarios and roadmaps for a circular economy based on organic waste resources in Naivasha.
UrbanCircle uses the REVAMP tool to help cities identify the opportunities in their organic waste.
SEI has taken the first step towards creating scenarios and roadmaps for a circular economy based on organic waste resources in Naivasha.
Poop is a sustainable alternative source of energy that could help reduce emissions that lead to climate change.
Resource recovery from sanitation and waste management can be a lucrative business. You can get it up and running in your city with support of the REVAMP tool.
In Chía, Colombia, inadequate waste management is putting lives and ecosystems at risk. We worked with locals to crunch data and calculate scenarios for change.
