Turning recycled wastewater into a commoditized resource : Valérie Issumo at TEDxLausanne

Sun, 03Mar2013 1 comment

The talk is titled: Wastewater, a resource or a weapon of mass destruction? 

Valérie shows us how to turn recycled wastewater into a commoditized resource, improve water sanitation, provide efficient water usage, and reduce price volatility.

….

Valérie Issumo is the CEO of Prana Sustainable Water company (http://www.pranasustainablewater.ch) . 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).

1st International IWA Conference on Holistic Sludge Management

Fri, 25Jan2013 2 comments

An IWA specialist conference

iwa-logo

6-8 May 2013
Västerås, Sweden

Websites: http://www.hsm2013.se/  and http://www.iwahq.org/1qh/events/iwa-events/2013/4.html

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.

Proposed Themes:

  • 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

IWA- the global network for water professionals

The International Water Association is a global reference point for water professionals, spanning the continuum between research and practice and covering all facets of the water cycle. Through its network of members and experts in research, practice, regulation, industry, consulting and manufacturing, IWA is in a better position than any other organisation to help water professionals create innovative, pragmatic and sustainable solutions to challenging global needs.

The strength of IWA lies in the professional and geographic diversity of its membership — a global mosaic of national, corporate and individual member communities. Our members are leaders in their field and represent:

  • Researchers – where solutions begin
  • Utilities – managing water services worldwide
  • Consultants – connecting problem owners with solution providers
  • Industry – creating sustainable water solutions
  • Regulators – safeguarding public health
  • Equipment manufacturers – translating ideas into products

The IWA network is structured to promote multi-level collaboration among its diverse membership groups, and to share the benefit of knowledge on water science and management worldwide. The Association helps make the right connections at the right time, thereby sharing cutting-edge research and practice that allows the water sector shape its future.

“Kartik Chandran is an Environmental Engineer. He is currently Associate Professor of Earth and Environmental Engineering at Columbia University, where he leads the Columbia University Biomolecular Environmental Science program and the Wastewater Treatment and Climate Change program. Under his stewardship, the research directions of biological wastewater treatment and biological nitrogen removal were established for the first time ever in the history of Columbia University. Chandran is keenly interested in developing novel models for sustainable sanitation and wastewater treatment, with a specific focus on managing the global nitrogen cycle (one of the grand challenges of the National Academy of Engineering) and linking it to the carbon cycle, the water cycle and the energy cycle. Chandran has received, among other awards, the NSF CAREER award and the Paul Busch Award. He was the recipient of a 2007 National Academies of Science Fellowship and a guest professorship at the Delft University of Technology. In 2011, Chandran began implementing a novel model for sanitation in Africa, supported by the Bill & Melinda Gates Foundation. He also serves on the Board of Trustees of the Water Environment Federation.”
