A critical review of ammonia recovery from anaerobic digestate of organic wastes via stripping
Renewable and Sustainable Energy Reviews, 2021 Anaerobic digestion is a well-established technology that valorises organic wastes to produce renewable energy as biogas. The ammonia released during this process can be inhibitory if it exceeds a threshold concentration.

The challenges of anaerobic digestion and the role of biochar in optimizing anaerobic digestion [PDF]
Waste Management, 2017 Biochar, like most other adsorbents, is a carbonaceous material, which is formed from the combustion of plant materials, in low-zero oxygen conditions and results in a material, which has the capacity to sorb chemicals onto its surfaces. Currently, research is being carried out to investigate the relevance of biochar in improving the soil ecosystem ...
