Developing a biogas centralised circular bioeconomy using agricultural residues - Challenges and opportunities
Feng, Lu; Aryal, Nabin; Li, Yeqing; Horn, Svein Jarle; James Ward, Alastair (Peer reviewed; Journal article, 2023-04-10)Anaerobic digestion (AD) can be used as a stand-alone process or integrated as part of a larger biorefining process to produce biofuels, biochemicals and fertiliser, and has the potential to play a central role in the ... -
Frequent export of pig slurry for outside storage reduced methane but not ammonia emissions in cold and warm seasons
Ma, Chun; Guldberg, Lise Bonne; Hansen, Michael Jørgen; Feng, Lu; Petersen, Søren O. (Peer reviewed; Journal article, 2023-07-15)Manure management is a significant source of methane (CH4) and ammonia (NH3), and there is an urgent need for strategies to reduce these emissions. More frequent export of manure for outside storage can lower gaseous ... -
Impact of slurry removal frequency on CH4 emission and subsequent biogas production; a one-year case study
Feng, Lu; Guldberg, Lise Bonne; Hansen, Michael Jørgen; Ma, Chun; Ohrt, Rikke Vinther; Møller, Henrik Bjarne (Peer reviewed; Journal article, 2022-06-22)Anaerobic digestion of animal slurry to produce biogas is the dominated treatment approach and a storage period is normally applied prior to digestion. Pre-storage, however, contributes to CH4 emissions and results in loss ... -
The role of electrochemical properties of biochar to promote methane production in anaerobic digestion
Ziyan, Sun; Feng, Lu; Yeqing, Li; Yongming, Han; hongjun, zhou; Junting, Pan (Peer reviewed; Journal article, 2022-08-15)The electrochemical properties of biochar may be the key factor to promote anaerobic digestion, which has attracted extensive attention. However, the mechanism and the role of the electrochemical properties of biochar are ...
