| The production of bioenergy in organic agriculture (OA) can reduce its dependency on fossil fuels and decrease greenhouse‐gases (GHG) emissions; consequently increasing the sustainability of organic farming. Different biomasses were characterized biologically and chemically for their biogas and bioethanol potential at organic farms in Denmark. Batch experiments indicated methane yield [GJ/ha]: 260.7 (fresh maize), 272.7 (maize silage), 127.1 (fresh rye), 169.7 (rye silage), 161.7 (dried rye), 110.5 (fresh clover), 117.8 (clover silage), 72.3 (dried clover), and 41.1 (dried vetch). Theoretical ethanol yield [GJ/ha] showed: 119.8 (fresh maize), 109.2 (maize silage), 36.9 (fresh rye), 39.9 (rye silage), 84.7 (dried rye), 28.9 (fresh clover), 24.4 (clover... |

| Anaerobic digestion of residual materials from animals and crops offers an opportunity to simultaneously produce bioenergy and plant fertilizers at single farms and in farm communities where input substrate materials and resulting digested residues are shared among member farms. A surplus benefit from this praxis may be the suppressing of propagules from harmful biological pest like animal parasites, pathogens, and weed seeds. In the BIOCONCENS project (http://www.icrofs.dk/Sider/Forskning/foejoIII_bioconcens.html) batch experiments were performed, where survival of six species of weeds and the pigs large roundworm Ascaris suum (non-embryonated eggs) was assessed under conditions similar to biogas plants managed at meso- (37°C) and thermophilic (50°C)... |

A surplus benefit from this praxis may be the suppressing of propagules from harmful biological pests like weeds and animal pathogens (e.g. parasites). In the present work, batch experiments were performed, where survival of seed of seven species of weeds and non-embryonated eggs of the large roundworm of pigs, Ascaris suum, was assessed under conditions similar to biogas plants managed at meso- (37 °C) and thermophilic (55 °C) conditions. Cattle manure was used as digestion... |
