Company profile
Technology revolutionizes the economics of wastewater treatment by generating instead of consuming
energy, utilizing electrogenic bacteria to produce electricity from wastewater while cleaning the water.
Conventional wastewater treatment uses 2% of the global power (80,000 MW and 57,000,000 tons per
year of CO2), amounting to $40B/year. Rather than using energy to treat wastewater, Emefcy harvests
renewable energy directly from the wastewater and feeds it to the grid. The total potential carbon
footprint reduction of Emefcy’s EBR’s technology is 76 million tons per year of CO2.
Emefcy’s solutions address industrial and manciple wastewater containing organic substance:
(1) Electricity solution (EBR) - Treating wastewater and producing green electricity as a byproduct. Ideal
for treating wastewater with a high concentration of organic substance
(2) Zero-Energy solution (DFX) - Treating wastewater with virtually zero energy required for aeration.
Ideal for treating wastewater with a low concentration of organic substance.

Background of the company
Emefcy founded by Eytan Levy and Ronen Shechter who also founded AqWise, an innovative wastewater
treatment solutions company, in 2000 a successful company active worldwide.

Technologies & products
General description:
Emefcy developed an Electrogenic Bioreactor (EBR) for treating wastewater whilst converting the organic
contamination in the wastewater to green electricity or Hydrogen.
The system is based on Microbial Fuel Cell technology that enhances the bacteria’s ability to produce
electric current as part of their metabolic activity. A layer of electro-active bacteria develops naturally
on the electrode surface area. While degrading the organic compounds of the wastewater, a bio-electrochemical
reaction occurs, generating electricity in the process.
Function of the product(s):
Treating industrial wastewater while utilizing the energy in the wastewater to produce green
electricity or hydrogen.
Objectives / Target companies
1. Industries with high concentration of organic matter in their wastewater (food & beverage, pharma,
chemicals, textile and pulp & paper industries). The offering will turn a wastewater plant to a profit
center using renewable energy.
2. An aerobic wastewater treatment plant for low organic contamination of wastewater (targeting municipal
wastewater treatment plants) and with an energy reduction of over 90% of typical aerobic processes.
