Value from sewage? New technology makes pig farming more environmentally friendly

Researchers from the Biological Systems Unit at the Okinawa Institute of Science and Technology Graduate University have created a system to treat both raw and aerated wastewater. The system relies on bacterial communities to break down organic material from raw wastewater and remove nitrate together with phosphate from aerated wastewater. It is easy to assemble and low maintenance. A proof-of-concept have been shown to work in both the lab and on a local swine farm in Okinawa, Japan.

BioAlchemy: Treating Wastewater at the point of production

Treating wastewater is an arduous process relying on complex sewage systems and treatment plants. While this is easier in developed areas with the requisite infrastructure, providing such services in rural areas is challenging. In recent years, decentralizing wastewater treatment — using devices to treat water locally — is increasingly seen as a preferable alternative. BioAlchemy […]
