Reusing grease from industrial wastewater to make biodiesel. (But that’s not all.)
Environmental tech developers for the industry; that is how they describe themselves. As such, former participant Zhana Solutions focuses on water management. One of the things they successfully developed is a patented electrochemical method to treat industrial wastewater more efficiently than conventional installations.
Besides wastewater treatment, they developed sustainable and circular solutions for grease separation and sustainable disposal of industrial kitchen discharges. Currently they are adapting their patented decontamination method for the creation of potable water.
After participating in ClimateLaunchpad (and making it to the 2019 Global Grand Final) they have been able to land their first customers, are running pilots and are in the midst of raising seed funding.
No chemicals, faster process
“We build grease traps”, says CEO Francisco Vivas. “Conventional grease traps look disgusting and they smell bad. Our G-Trap takes the cooking oils and other food grease out of dishwasher machines in industrial kitchens or other industrial wastewater.”
“Our system is unique, because it is much more efficient in OPEX, treatment speed, size of plant and sludge production.”
Key to their solution is that they don’t add chemicals to the water. “Because then you have don’t just have grease and waste in the water, but also chemicals”, Francisco explains. “What we do is we use an advanced electro chemistry. The geometry of the electrodes is what makes it so advanced. Regular electro chemistry uses square chemicals, leading to a bi-dimensional effect, while we use three techniques to create a three-dimensional effect. That makes our process 5 to 10 times faster. It also allows for smaller plants, significantly reducing costs.”
