An economist, she worked for 15 years as a soft commodities trader and as a trainer in Belgium, Uruguay, Cameroon and Switzerland. Throughout her career she has fought for sustainability and risk mitigation in the entire value chain of traded goods. She is a university lecturer and also a consultant for food security, socially responsible investments, pricing ecosystems and the assessment of water interdependencies. Valérie holds an MBA, has studied at various international water centres, and was a recipient of the Prize of the Belgian Minister of Foreign Trade.
Prana Sustainable Water is acting for the following challenges:
- Reducing the 80% untreated wastewater (UNEP) by matching offers and pre-paid demands of treated water allowing to finance sanitation and restore the public water quality as common good for not hindering growth and strategies.
- Water is the underlying commodity of every goods or services: please check www.cdproject.net/water and www.waterfootprint.org: : Prana Sustainable Water has designed Ethical Water Titles© – futures contracts – to commoditize treated wastewater as tradable resource on the Ethical Water Exchange platform or commodities exchange for water procurement and price security.
- Scaling-up clean technologies for wastewater:the members of Prana Sustainable Water Club active in wastewater can benefit organized markets through solvent demands of recycled water via Ethical Water Titles© allowing to leapfrog the leverage effects solving simultaneously water, health, economic, environmental and social issues.
- Offset water consumption : wastewater can be recycled on an infinite basis. Prana Sustainable Water boosts responsible productions or services prioritizing reuse water with the automatic respect of the Water Exploitation Index growingblue.com and storing part of recycled wastewater into green water bnks© for philanthropy, reforestation and production of green/rain water, energy, public services like fires..etc…
- Defense and food security Our motto is to incentivize responsible water use to produce:
– what makes sense (prioritizing commoditized recycled water from wastewater for Human Rights, for water footprints of functional food or with high nutritional value and ecosystems services),
– where it makes sense (according to the impact),
– how it makes sense (with treated wastewater and sludge energy).

Waterless Urinals do not require water for flushing and can be promoted at homes, institutions and public places to save water, energy and to harvest urine as a resource. Reduction in infrastructure required for water supply and waste water treatment is also a spinoff arising from installing waterless urinals. The concept, founded on the principles of ecological sanitation helps in preventing environmental damage caused by conventional flush sanitation systems.
In recent years, Human Urine has been identified as a potential resource that can be beneficially used for agriculture and industrial purposes. Human urine contains significant portion of essential plant nutrients such as nitrogen, phosphate and potassium excreted by human beings. Urine and faeces can also be separated employing systems such as urine diverting toilets. In the light of diminishing world’s phosphate and oil reserves which determine availability as well as pricing of mineral fertilisers, harvesting urine for reuse in agriculture assumes significant importance. Akin to the movement for harvesting rain water, urine harvesting is a concept which could have huge implications for resource conservation.

When looking at sanitation/wastewater treatment and making it economically feasible for more parts of the world, this is very interesting research. Some will say it has roots in the fact that there is “gold” in out crap…

…On May 1, a panel of judges awarded the $100,000 National University Clean Energy Business Challenge prize to the Stanford team for its project to convert nitrogen waste into nitrous oxide that is then used for clean power generation….
A new process for the removal of nitrogen from wastewater is introduced. The process involves three steps: (1) partial nitrification of NH4+ to NO2−; (2) partial anoxic reduction of NO2− to N2O; and (3) N2O conversion to N2 with energy recovery by either catalytic decomposition to N2 and O2 or use of N2O to oxidize biogas CH4. Steps 1 and 3 have been previously established at full-scale. Accordingly, bench-scale experiments focused on step 2. Two strategies were evaluated and found to be effective: in the first, Fe(II) was used to abiotically reduce NO2− to N2O; in the second, COD stored as polyhydroxybutyrate (PHB) was used as the electron donor for partial heterotrophic reduction of NO2− to N2O. ….
Normally, we want to discourage these gases from forming,” said Craig Criddle, a professor of civil and environmental engineering and senior fellow at the Woods Institute for the Environment at Stanford. “But by encouraging the formation of nitrous oxide, we can remove harmful nitrogen from the water and simultaneously increase methane production for use as fuel.

The purpose of this conference is to provide a forum for researchers and practitioners to exchange the latest developments in sludge management.It will give possibilities to examine and discuss the different challenges connected to resource recovery through treatment and disposal of wastewater sludge.
The conference covers sludge management and anaerobic digestion with a broad holistic system perspective. It includes the recycling of nutrients such as phosphorus and nitrogen by focusing on upstream treatment to reduce harmful substances in wastewater, as well as on the production of biogas as a fuel for vehicles. The certification of treated sludge is another important condition for the possibilities to recycle sludge to farmland areas.
Conference also want to share knowledge, practices and ideas for the future directions of process development. The sludge treatment is one of the key issues to be solved. The aim of the conference is to take a major step forward to where all aspects of sludge management are addressed.
- Production and utilization of biogas
- Nutrient recovery processes
- Processes for hygienization of sludge
- The need for a holistic approach including i.e. environmental effects from sludge handling/management in the total performance efficiency of wastewater treatment
- Use of sludge for energy generation including combustion and supercritical gasification
- Emerging contaminants in sludge – upstream separation and optimization to decrease negative effects by detoxification
- Physical and chemical pre-treatment processes, including chemical conditioning, thickening, dewatering, drying
- Modelling of anaerobic processes
- Methane emission from sludge treatment

- The human health implications of climate change must be afforded greater prominence.
- Governments, the private sector, financiers, and society have a moral responsibility to practice socially responsible investment and to mitigate against the impact of climate change, particularly in relation to human health.
- Human health must be a core, not peripheral, focus in future climate change deliberations.
- The health community, led by health ministers, must play a central role in climate change deliberations.
- Health ethics principles must be afforded equal status to economics principles in climate change deliberations.

- Climate change is a public health problem. Evidence from many sectors shows substantial health impacts of climate change, particularly for the most vulnerable: the poorest, the youngest, and the oldest.
- Human health and climate change are closely connected. Within the global United Nations (UN) process, health is seen as the most direct component linking climate change and individual lives.
- Public health actions in relation to climate change are needed. Top-down advocacy on health and climate at the UN level needs to be mirrored by bottom-up public health actions that bring health and climate co-benefits.
“PLoS Medicine is the leading open-access medical journal, providing an innovative and influential venue for research and comment on the major challenges to human he
alth worldwide. We specifically seek to publish papers which have relevance across a range of settings and that address the major environmental, social, and political determinants of health, as well as the biological.”
