Ecoremedy patents biosolid treatment solution in U.S.

May 23, 2023
The patented system dries and gasifies biosolids to convert them into beneficial-use products without resorting to incineration.

Ecoremedy® LLC announced that it has patented its Biosolid Treatment Process and System through the U.S. Patent and Trademark Office.

Issued under patent No. 11,629,301, the innovation addresses one of the most challenging residuals conversion and disposal issue, providing an alternative to increasingly problematic municipal biosolids management practices.

The patent describes the system as one that “treats human biosolids to produce thermal energy for self-consumption for the production of beneficial use products including low carbon ash, high carbon acvitvated biochar, and Class A biosolids.”

The system conveys a biosolid into a dryer to create one of the beneficial use products, and into a gasifier to create two other beneficial use products.

Ecoremedy says that its process — ruled as non-incineration by the U.S. Environmental Protection Agency — avoids the production of highly toxic and carcinogenic dioxins and furans commonly produced by incineration.

“This is an important milestone in our development of a modular and scalable solution that uses thermal energy to remove moisture from biosolids, breaks down harmful chemicals and produces a biochar with desirable properties and minimal environmental footprint,” said David Mooney, Ecoremedy’s President, Chief Technology Officer and patent inventor. “It strengthens Ecoremedy’s competitive position and validates our design of the world’s most advanced platform for simultaneous gasification, pyrolysis, nutrient and energy recovery from municipal biosolids and industrial residuals.”

Ecoremedy designs complete biosolid drying and gasification facilities for wastewater treatment and other challenging organic wastes.
