Greenhouse gas emissions from digestate in soil [PDF]
International Journal of Recycling of Organic Waste in Agriculture, 2020 Purpose Biogas residues, digestates, contain valuable nutrients and are therefore suitable as agricultural fertilizers. However, the application of fertilizers, including digestates, can enhance greenhouse gas (GHG) emissions.

Investigating Horticultural Applications of Liquid Digestate
, 2023 Background. Sixty percent of global crop production depends on inorganic fertiliser, supporting nearly half of the world’s population. However, this pro- duction accounts for 1.6% of global CO2 emissions and is based on increasingly unreliable, finite resources. Thus, there is an urgent need to find sustainable alternatives.

Biological treatment of sludge digester liquids
Water Science and Technology, 2006 Nitrogen removal in side stream processes offers a good potential for upgrading wastewater treatment plants (WWTPs) that need to meet stricter effluent standards. Removing nutrients from these internal process flows significantly reduces the N-load to the main treatment plant.

Changes in the Composition of Digestate Liquid Fraction after Ozone and Ultrasonic Post-Treatment
Energies, 2022 There is a growing concern about environmental pollution with digestate, which is produced in significant amounts in the anaerobic digestion process. The inappropriate application of digestate in agriculture may lead to ammonia emission to the atmosphere,
