Converting wastewater to fertilizer with fungal treatment

ScienceDaily / 2h

Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process. Two studies explore the use of a fungal treatment to convert the leftover wastewater into fertilizer for agricultural

Patients with Alzheimer's disease have higher frequency of mental health symptoms which can precede memory problems, study finds
