WSU, PNNL Convert Biofuel Waste Into Commodity, Now Targeting Sewage Sludge
Richland, WA (10/6/17) -- The process of converting algae into a biofuel is a two-step process. In the first step, hydrothermal liquefaction, a portion of carbon and nutrients are left behind. A team of researchers from the Washington State University have found a way to adapt anaerobic microbes to break down those nutrients into a bionatural gas or fertilizer. The research team is now partnering with Pacific Northwest National Laboratory (PNNL) to research how to convert sewage sludge into fuel. This research article is saved in the MABA Members Site or can be purchased “Anaerobic digestion of organic fraction from hydrothermal liquefied algae wastewater byproduct”.

Phosphorus Availability of Sewage Sludge-Based Fertilizers Determined by the Diffusive Gradients in Thin Films (DGT) Technique
Journal of Plant Nutrition and Soil Science (9/10/17) -- Researchers used “diffusive gradients in thin films (DGT) technique to quantify the plant P availability of various types of P fertilizers with a novel focus on sewage sludge-based P fertilizers.” This experiment was done as a way to explore alternative ways to measure plant available P outside of pot and field experiments.

Researchers Take the 'Stink' Out of Wastewater Treatment
Okanagan, BC, Canada (10/10/17) -- Researchers from University of British Columbia’s Okanagan campus have experimented with adding various metal salts during the anaerobic digestion process in wastewater treatment plants to reduce odors. By adding the metal salts during the fermentation process of the treatment, the researchers saw a reduction in sulfuric gases produced, a decrease in pathogenic fecal coliforms, and found it easier to extract water from the treated sludge.The research article mentioned in this news item is available on the Members Site and can be purchased “Assessing iron and aluminum-based coagulants for odour and pathogen reductions in sludge digesters and enhanced digestate dewaterability”
