Water is the common element of every goods and services.

The value and level of cleanliness of reclaimed water depend on the item or service produced thanks to this water.h20

Renewable and clean energy can be generated thanks to wastewater.

For example, algae can grow on wastewater, clean it and be transformed into biofuel and/or treated wastewater can be used for gravity energy.

Pooling resources can be also applicable for funding climate friendly energy infrastructure projects.

For blended finance we collaborate with Blue Yellow a  fintech platform connecting renewable energy projects with investors.

A wastewater plant can produce more energy than it needs and can be a “green power station” with anaerobic digestion during which micro-organisms break down materials from wastewater (to which solid bio-wastes can be added). The biogas/methane gas produced from this process is then used to generate heat and electricity.


Are you interested not only to ‘offset’ your carbon footprint and  to know exactly


your CO2 carbon footprint has been sequestered and absorbed?


Gold, silver or other metals can be recovered from wastewater (see: www.eawag.ch)

For example, chromium used in metal-plating industries or leather tanning can be recovered thanks to specific filters and technology. Chromium-6 (hexavalent chromium) bath can be re-used/re-cycled for few cycles of plating or dyes by filtering iron and other contents. This also enhances the quality of plating. The sludge that comes out after filtration can then be valorized safely into clean water and/or biogas and/or other outputs.

Recovering nutrients from wastewater is key for healthy food security and for sustainability. 
For example Phosphorus is used for fertilisers, animal feed additive, treatment of metals, batteries, fire extinguishers, ...etc.
Other example Ammonia in wastewater is a contaminant and hazardous to the environment. Ammonia in a fuel cell is nonetheless energy dense in volume and comparable to hydrogen in performance.

Transforming wastewater sludge in bio-cements can:

  • decrease the cement industry greenhouse gas emissions
  • reduce long distance transport of this construction material
  • enhance the durability of building materials and structures

Algae grown on wastewater from livestock farms, municipalities, distilleries, etc. can be transformed into biofuels or biopolymer.

Methylene blue dye can be recovered from textile or tannery wastewater and reuse e.g. to store and to produce energy.
