Giving water industry waste residuals a second life The tool to accomplish the road from idea to value Jouke Boorsma Business developer 1
Content of the presentation - Introduction Aquaminerals - Selection of residuals - Lessons learned in the Netherlands
The “tool” AquaMinerals • Not-for-profit (but maximizing $$ for participants). • Collective: selling and innovation strength, inclusive of mandate! • Collective: division of risk • Focus on finances, sustainability and to unburden the shareholders • Max 20% sales volume for non-shareholders 3
Our tasks (both drinking water companies and water authorities • Development of new products and markets • Supporting existing products and markets • Advise on laws and regulations • Delivery to market 4
Selection of residuals in the wastewater treatment plant Biogas CO2 Heat Vivianite Struvite Phosphate Cellulose Screening waste Fat Kaumera Bio-plastics Nitrogen Water Sand 5
Example: Calcite from the drinking water sector Changing softening process, changing seeding material from sand to calcite
Calcite Successful: - some water companies changing process - availability of sand-free calcite, new applications potentially possible
Example: cellulose from wastewater
Example: water reuse
Creating circular products, lessons learned • Entrepreneurship and the water 1 authorities • Translation of ambitions into the organisation, not that easy. 10
Example failure (1/3) - Calcite in cubicle cows - Hygienic alternative for hay - Germ count in milk lower - Locally lot of clients - Price / costs OK - No certificates needed Failed: calcite sank to bottom manure cellar and was very difficult to remove
Example failure (2/3) - Calcite for fracking - Alternative ceramic balls - Better CO 2 -footprint - No processing needed - (VERY) good price Failed: Drinking Water Companies (our shareholders) fight permits for fracking, so no basis for cooperation on supply
Example failure (3/3) - Calcite in ceramics - White calcite fits perfectly, test OK - Nice imago: locally processed and used in bathroom - Good prices - Support by senior management Failed: Apparently very powerful plant manager refuses to do endurance tests. Production lines too busy.
Finally With perseverance, targeted activities and suitable partners we ensure that raw materials arrive at the right place at the right time, in the right composition And so we no longer have any waste
