The increasing global population is placing pressure on the water resources and nutrients needed for food production, while increasing the amount of waste generated and the environmental contamination. Technical solutions and changes in the social perception of the environmental problems are needed to address these problems. The blackwater (wastewater from toilets only) represents the major proportion of the plant nutrients found in household wastewater (about 90 % of… Expand
Ammonia sanitization of blackwater for safe use as fertilizer.
TLDR
The treatment time needed to meet the requirement for Salmonella and E. coli reduction could be reduced at least six-fold and the enterococci were more persistent, and only the highest treatment doses had a significantly higher inactivation than the controls. Expand
Fate of pharmaceuticals and perfluoroalkyl substances during source separated wastewater treatment
In the past decade, water reuse and nutrient recycling of wastewater has gained more attention as sustainable water cycle management solutions, driven by the increasingly noticeable resourceExpand

Local recycling of plant nutrients from small-scale wastewater systems to farmland—A Swedish scenario study
Abstract Reducing the negative impact from on-site systems and promoting recycling are important tasks for municipal authorities, especially as regards phosphorus. The objective of this scenarioExpand
Fertiliser products from new sanitation systems: their potential values and risks.
TLDR
The products deriving from new sanitation systems have a high potential to preserve available plant nutrient resources and deficiencies in agriculture as well as being able to substitute synthetic plant nutrients and at the same time prevent unwanted environmental nutrient over-enrichment. Expand
Comparison of environmental effects and resource consumption for different wastewater and organic waste management systems in a new city area in Sweden.
TLDR
An analysis of the environmental effects and resource consumption by four systems for management of wastewater and organic household waste in a new city area found different systems can be considered to be the most advantageous. Expand
Ecological Sanitation--a way to solve global sanitation problems?
TLDR
The paper presents an introduction to EcoSan principles and concepts including re-use aspects (available nutrients and occurring risks), and case studies of EcoSan concepts in both industrialized and developing countries. Expand
The potential for self-sanitisation of faecal sludge by intrinsic ammonia.
TLDR
Faecal sludge can be sanitised by airtight storage without the use of additives when flush water volumes are sufficiently low, mainly due to increased uncharged ammonia (NH3) concentration. Expand
Comparison of composting, storage and urea treatment for sanitising of faecal matter and manure.
TLDR
Two alternatives for this treatment, thermophilic composting and ammonia-based treatment, were evaluated and compared to storage treatment, and the storage period tested resulted in slow reduction of faecal coliforms, Salmonella spp. Expand

Abstract The potential negative environmental impact of manure and biological waste (BW) can be minimised at a profit by recycling plant nutrients in the food chain. Current large-scale livestockExpand
Life cycle assessment of conventional and source separation systems for urban wastewater management
Source-separation systems for urban wastewater management collect the different wastewater flows separately to facilitate the recovery of valuable resources from wastewater (energy, nutrients). Thus,Expand
Possibilities for sustainable nutrient recycling by faecal separation combined with urine
TLDR
Changing to urine-diversion combined with faecal separation and disinfection by urea seems to be an interesting way to decrease the resource usage and possibly improve the hygienic standard of wastewater systems. Expand
