Process to Enable Transport for Further Digestion with Anaerobic Digestion

BioHiTech Testing Tanking Process for Effluent from Aerobic Food Digesters

BioHiTech America, which develops high-tech data driven solutions for food waste disposal, is testing a process that will allow the effluent from company’s aerobic Eco-Safe Digesters to be tanked and transported for further digestion at AD facilities.

Chestnut Ridge, New York based BioHiTech America, which develops high-tech data driven solutions for food waste disposal, has partnered with Natural Systems Utilities, Ridgewood Green RME and the Village of Ridgewood, New Jersey to test a process that will allow the effluent from company’s aerobic Eco-Safe Digesters to be tanked and transported for further digestion at Anaerobic Digestion (AD) facilities.

BioHiTech America, a subsidiary of BioHiTech Global, Inc. (OTC: BHTG),

Explained that its Eco-Safe Digester utilises an aerobic digestion process to convert food waste into grey water, also referred to as effluent.

Typically the effluent is discharged into the sewage system and individual wastewater treatment facilities to treat it with other sanitary waste. However, the company said that its new process will tank the unit’s effluent allowing for transportation to an anaerobic digestion plant where biogas can be captured and used to create renewable energy. 

The company explained that the Eco-Safe Digester performs the hydrolysis stage of anaerobic digestion at the point of origin. Because the aerobic digestion process begins with the breakdown of solid organics to a liquid slurry, the effluent is said to be easily pumped and transported, arriving at the AD facility in a ‘predigested’ condition allowing for efficient feedstock transfer and eliminating the need for costly processing at the AD facility. 

“We have developed a process for those who want their food waste delivered to anaerobic digesters so that it can be converted to clean energy,” said Frank E. Celli, CEO of BioHiTech Global. 

Paul Knowles, director of technical operations of Natural Systems Utilities. Added: “Early trials to receive the material and feed it to the digester have proven successful. We are working with BioHiTech to expand the process so that they can offer this solution to new and existing customers.”

The new process is currently being tested at a high-volume supermarket in New Jersey and transported to an anaerobic digestion facility operated by the Village of Ridgewood at its water pollution control facility. 

Ridgewood Green RME, owns a 20,000 gallon (75,700 litre) per day liquid waste receiving facility and a 240 kW biogas power plant that is co-located at the anaerobic digestion facility. 

Natural Systems Utilities operates those components of the project owned by Ridgewood Green RME.
