The United Nations Millennium Development Goals have called issues of water and sanitation to the forefront international development efforts. Engineers other workers are answering this call in increasing numbers. In order achieve these goals it is necessary overcome historically low sustainability rates projects. This paper presents a logical framework for identifying analyzing factors that affect sustainable It identifies five common literature policies aid organizations: (1) sociocultural...
Wastewater treatment in low and lower-middle income countries is often limited by lack of local technical expertise, institutional capacity, financial resources, making it challenging to reach SDG6-target 6.3, i.e. halving the proportion untreated wastewater. Several studies suggest sets sustainability indicators for assessing planning and/or operation WWTPs. However, existing standard are typically focused on context high upper-middle countries, whereas face other types issues. The...
Urban sanitation presents one of the most significant service delivery challenges related to poverty alleviation and sustainable development in developing world. The past decade has witnessed innovations approaches for unserved rural urban settlements with a clear policy shift community-based that attempt overcome supply-led, over-engineered solutions decades. This article two examples new developments: urban-focussed household-centred environmental (HCES) rural-focussed community-led total...
The sanitation ladder is a useful tool that being used to monitor progress towards the target of MDGs. This could be even more if it can refined based on functions systems rather than hierarchy predefined technologies. paper presents seven-rung function-based where broadly divided into health and environmental functions. proposed intended as an inspiration for nations, JMP, move technology-based monitoring progress. A functional approach e.g. MDGs would require some major shifts in methods...
Source-separating sanitation systems offer the possibility of recycling nutrients present in wastewater as crop fertilisers. Thereby, they can reduce agriculture's impacts on global sources, sinks, and cycles for nitrogen phosphorous, well their associated environmental costs. However, it has been broadly assumed that people would be reluctant to perform new behaviours are necessary implementing such practice. Yet, few studies have tried systematically gather evidence support this...
With growing urbanization cities become hotspots for nutrients. Food items are imported and food residues, including excreta not-eaten food, often exported to landfill sites water bodies. However, urban sanitation systems can be designed achieve a high degree of nutrient recovery security while counteracting current resources depletion, environmental degradation wasteful energy use. This article illustrates how an extended solid waste hierarchy also human wastewater guide actions save...
Purpose In today’s complex society, there is an increasing demand to include a wider set of skills in engineering curricula, especially related policy, society and sustainable development. Role-playing gaming are active learning tools, which useful for relationships between technology problem solving situations communication. However, use these methods higher education, particularly, limited. The purpose this study was test the effectiveness role-playing game about complexities water...
Sanitation systems based on source separation and valorisation of human urine can improve the environmental sustainability wastewater management. Yet, social acceptability such new, resource-oriented sanitation practices have not been assessed systematically. We attempt to address this research gap by reporting findings a survey conducted at South Indian university that evaluated support for recycling among 1252 consumers. place our in context Theory Planned Behaviour, quantify consumer...
Adopting urine-recycling technologies can support a transition to circular nutrient management systems. Although these have been developed since the 1990s, their large-scale implementation remains limited. From technological innovation system (TIS) perspective, "knowledge development and diffusion" is critical function in phase. Yet, available methods literature evaluate this are not standardized. Hence, study aims fill gap by developing novel multi-criteria framework for evaluating...
Drawing on collective experience from ten collaborative research projects focused the Global South, we identify three major challenges that impede translation of sustainability and resilience into better-informed choices by individuals policy-makers in turn can support transformation to a sustainable future. The comprise: (i) converting knowledge produced during successful application; (ii) scaling up time when are short-term potential impacts long-term; (iii) across space, local sites...
Achieving a more circular and efficient use of nutrients found in human excreta domestic (municipal) wastewater is an integral part mitigating aquatic nutrient pollution insecurity. A synthesis research trends readily available to various stakeholders much needed. This systematic map collates summarizes scientific on technologies that facilitate the recovery reuse plant organic matter wastewater. We present evidence way can be navigated easily. hope this work will help with uptake upscaling...
As global consumption expands, the world is increasingly facing threats to resource availability and food security. To meet future demands, agricultural efficiency needs be optimized for both water nutrients. Policy makers should start radically rethink nutrient management across entire chain. Closing loop by recycling nutrients in waste excreta an important way of limiting use mineral nutrients, as well improving national This article presents a framework sustainable discusses...
The report is a product arising from the work of Sustainable Sanitation Alliance which was initiated prior to International Year in 2008 an attempt inject sustainable development ideas into sanitation sector. It functions as vision document for those policymakers, researchers and practitioners that are striving towards fundamental reform improvements within sector both rural urban populations all countries world. reviews global progress being made achieving Millennium Development Goal (MDG)...

Implementation of resource recovery technologies is becoming increasingly important, as humans are exhausting the world's natural resources. Recovering nutrients and water from wastewater treatment systems will play an important role in changing current trends towards a circular economy. However, guidance still needed to determine most appropriate way do this. In this study two decision-support tools, sanitation planning software (Santiago) life cycle assessment (LCA), were applied identify...
There is a growing trend for nutrient recovery from wastewater as part of the transition to circular economy. Most nutrients in household originate urine and one way facilitate reuse these concentrate into fertiliser products. Urine concentration technologies are still development phase not implemented at scale. The aim this study was provide guidance technology developers policymakers by assessing environmental societal impacts technologies. In particular, it includes practical aspects such...
In this study, we explored why urine recycling systems have failed to gain wide-scale expansion despite their high potential for food and fertilizer security. Additionally, examined the future perception of in Sweden Switzerland, as these two countries are at forefront technological advancement. Along with identifying barriers, also proposed pathways overcoming those barriers achieving upscale. The analysis was conducted using innovation (TIS) approach, which is technology-focused, i.e.,...
Safe recycling of nutrients found in human excreta back to agriculture is an important component a circular economy that can protect waterways and stabilize food prices. Although many technological advances for the recovery these exist, large-scale implementation lacking. A commonly cited barrier lack acceptance fertilizers from products grown with such fertilizers. The retail sector, as intermediary between producers consumers, actor power influence opinions purchasing practices. In this...
