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 ...

Environmental Assessment of a Multifunctional Process Coupling Anaerobic Digestion and Pyrolysis
Chemical Engineering Transactions, 2021 Anaerobic digestion (AD) is a waste treatment technology based on organic matter degradation by microorganisms in the absence of oxygen. This process generates two valuables products, biogas and digestate. While biogas is recognized and exploited for its

Lactic acid production from food waste at an anaerobic digestion biorefinery: effect of digestate recirculation and sucrose supplementation [PDF]
, 2023 Low lactic acid (LA) yields from direct food waste (FW) fermentation restrict this production pathway. However, nitrogen and other nutrients within FW digestate, in combination with sucrose supplementation, may enhance LA production and improve ...

The Effect of Homogenized Biosolution Allocation in the Digestate on Reducing Ammonia Emissions
Engineering Proceedings, 2023 Digestate (anaerobic ferment) is an organic substance remaining after the anaerobic processing of organic matter or biodegradable waste—biogas extraction or anaerobic alcoholic fermentation— or bioethanol extraction.
