Don’t Throw That Out! Turning Dairy Waste into Microalgae Products.

Wastewater produced on dairy farms can be a tough challenge for small and medium sized farms. High-tech treatment methods work for large farms, but smaller farms need a more effective way to treat their wastewater. Discharged without treatment, wastewater can highly endanger aquatic systems, deteriorate water quality, and has cost the US billions annually to clean up. This study’s research shows the potential to turn that waste back into commercial products by growing microalgae. Because wastewater is rich in the nutrients microalgae need to grow, it can be harvested and turned into biofuels, biofertilizers, animal feed, and other products. This provides smaller farms with a method to treat their wastewater and turn it into a usable commercial product.
