Turning Waste into Wealth: A Self-Sustaining System for Clean Water and Energy

Self-sustaining system to recover clean water, renewable energy, and valuable products from animal manure wastewater

Unmet Need: Treatment and processing of animal manure wastewater

Self-sustaining technology for manure treatment transforms a potential environmental liability into valuable resources, benefiting both the environment and the agricultural sector.

This self-sustaining technology not only facilitates the production of high-quality biogas but also ensures the recovery of clean water and the conversion of waste into valuable by-products, including ammonium bicarbonate fertilizer and Class A biosolid digestate. The system developed by WSU researchers includes stripping, evaporation, and condensation methods to separate ammonia and water from animal manure wastewater and absorption method to capture ammonia using biogas CO2 and water.

Technology: A novel technology that recovers clean water and valuable products from animal manure wastewater

Researchers at WSU have developed a novel technology to recover clean water and valuable products from animal manure wastewater in a self-sustaining manner. The system includes in-situ anaerobic digestion (AD) stripping evaporation system. Using this technology, WSU researchers have introduced two compelling aspects that set it apart from conventional approaches: Firstly, it’s inherently self-sufficient, harnessing self-produced bioenergy to drive its operations and secondly, this system reimagines the entire process by integrating multiple operations into a single-step solution. This technology lies in a holistic approach, positioning this system as a transformative solution in the domain of agricultural wastewater management.
