Anaerobic digestate management, environmental impacts, and techno-economic challenges [PDF]
Waste Management, 2022 Digestate is a nutrient-rich by-product from organic waste anaerobic digestion but can contribute to nutrient pollution without comprehensive management strategies. Some nutrient pollution impacts include harmful algal blooms, hypoxia, and eutrophication.
