The document discusses rethinking resource recovery from wastewater by focusing on human urine as a valuable nutrient source. It provides examples of projects that recover nutrients from urine through processes like struvite precipitation and treatment with willow plants. These approaches can help close nutrient loops and reduce costs compared to conventional wastewater treatment. The document advocates for viewing human excreta as a resource rather than a waste and designing sanitation systems accordingly.

Sydney's Water Sustainability | Biocity StudioBiocity Studio
Sydney is experiencing long-term droughts, low rainfall and a high demand for water. What can we do to help solve the water crisis? Water restrictions are only a short-term fix. Other solutions are desalination and recycle water plants, water management, and artificial precipitation.
Sydney’s Water Sustainability | Biocity StudioBiocity Studio
According to the CSIRO Sydney rainfall will decrease by 3% while population will increase, amounting to an increase of 20% more water by 2030. Currently Sydney is recycling 25 billion litres per year; by 2015 we will be recycling up to 70 million litres. 12% of Sydney’s water usage will be recycled water.
Grey water systems presentation 6 18-2015 finalTony Green
The recent drought has prompted Governor Brown to enact
mandatory water restrictions for the first time in the history of the state of California. With no end to the drought in sight and the level of the state’s reservoirs being at their lowest levels in decades everyone will need to take steps to conserve this precious resource. Grey Water systems have recently been proposed as a method where home owners can help conserve water by using reclaimed
water produced by laundry, sinks and bathtubs in non-potable applications such as irrigation or flushing toilets.

Sydney’s water demand is currently met by 11 major damns, recycled water and water pumped from the Shoalhaven River. Warragamba dam provides Sydney with 80% of Sydney drinking water supply. Sydney’s high demand for water has forced the NSW Government to come up with a Metropolitan Plan for Sydney, by creating more Grey water, Water efficiency programs, Desalination Plant and early lead detection.
Saturated Sodium chloride brine can be produced by desalination of seawater.Such high purity brine will become the raw material for the production of Caustic soda and Soda ash.This slide show explains how.

C5.07: Blue Carbon: Current status of Australian estimates and future model p...Blue Planet Symposium
Blue carbon is becoming widely recognised as a critical component of all national carbon accounting schemes. Australia has invested heavily in collating existing estimates of blue carbon stocks and is currently targeting important yet poorly represented habitats around its extensive coastline. Much of this effort is linked with the CSIRO-funded Coastal Carbon Cluster. This 3-year program has developed and validated many approaches to blue carbon estimation and is now able to showcase best-practice methods. The activities of the Cluster have been used as a model for international efforts to develop global estimates, as well as national blue carbon inventories via the International Blue Carbon Scientific Working Group. Finally, static estimates of carbon can only describe the current carbon stock at a specific location; models can extrapolate these relationships into unsampled regions, as well as estimate carbon stock into the future given changes to climate as well as alterations to the geochemistry/hydrodynamics of a specific habitat.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

17. Flow or Stream of Materials
•We Excrete most of the Nutrients we
Consume
•Human Urine contributes with only 1
% of the Volume of Household
Wastewater but contains 80 % of N, 55
% of P and 60 % of K and less than 0.6
% of Cadmium and 0.06 % of Lead
18. Phosphorus
•One Person Excrete 1 KG P/year.
•0.7 KG in Urine and 0.3 KG in Faeces.
•Human Phosphorus Returned to Soil
Would Cover 80 % of P Demand
•In Agriculture Short of Phosphorus
Human Excreta could be a Golden
Opportunity.
•In 100 years Phosphorus Could Be Gone.
22. 1) The first urine product is urine stabilized by
nitrification and destillated resulting in
amonium nitrate + P + S with a final water
content of 4 %.
2) The second urine product is struvite
(MgNH4PO4*6H2O), which precipitates when
magnesium oxide is added to human urine.
Struvite is mainly a phosphorus fertilizer
3) The third urine product is ammonium sulphate,
where ammonia is stripped using sulphuric acid
