Characterisation of most relevant feedstock for biogas and bioethanol production in organic farming Organic Eprints
Oleskowicz-Popiel, Piotr; Thomsen, Mette Hedegaard; Nielsen, Henrik Bangsø; Schmidt, Jens Ejbye; Thomsen, Anne Belinda.
Bioenergy production from local bioresources has a great potential. It is important to reduce dependency on fossil fuels and decrease green house gas emission in organic agriculture (OA). Both biogas and bioethanol can be produced in OA and significantly contribute to the sustainability of organic farms. Soil fertility is the basis for OA: it has been of concern that the fertility might decline if most of the organic residues were converted into energy and only effluent from anaerobic digestion process was recycled. However, by intelligent management of organic residues and crop rotation it is possible to avoid decrease of soil fertility and at the same time produce renewable energy. The presented study is part of the BioConcens project...

BioConcens: Biomass and bioenergy production agriculture – consequences for soil fertility, environment, spread of animal parasites and socio-economy Organic Eprints
Oleskowicz-Popiel, P; Ambus, P; Carter, M.S.; Dalgaard, T.; Hauggaard-Nielsen, H; Johansen, A; Jørgensen, U; Nielsen, A.M; Nielsen, H.B.; Nielsen, L.H; Olesen, J.E.; Roepstorff, A; Skytte, K; Schmidt, J.E.; Thomsen, A.B.; Thomsen, M.H.; Jensen, E.S..
The research programme called “international research cooperation and organic integrity” was commenced for a period 2006-2010. It is coordinated by DARCOF (The Danish Research Centre for Organic Farming). The whole programme, with acronym DARCOF III, consists of 15 projects (http://www.darcof.dk/research/darcofiii/index.html). One of them is BIOCONCENS - Biomass and bioenergy production in organic farming – consequences for soil fertility, environment, spread of animal parasites and socio-economy (http://www.bioconcens.elr.dk/uk/). The production of bioenergy in organic agriculture (OA) can reduce its dependency of fossil fuels and decrease green house gasses emission; consequently it will increase sustainability of organic farms. Biorefinery concept based...

Erhalt ökologisch wertvoller Grünlandstandorte durch eine Integrierte Festbrennstoff- und Biogasproduktion aus Biomasse (IFBB-Verfahren) Organic Eprints
Richter, M.sc. Felix; Kuschnereit, M.sc. Sara; Graß, Dr. Rüdiger; Fricke, Dipl.-Ing. agr. Thomas; Wachendorf, Prof. Dr. Michael.
As a new utilisation concept for the conservation of ecologically valuable habitats the integrated generation of solid fuel and biogas from biomass (IFBB) was tested on five semi-natural grasslands from typical German mountain areas. Through hydrothermal conditioning and mechanical dehydration grassland silage was separated into a press cake and a press fluid. In anaerobic digestion experiments with press fluids methane yields of 304 to 522 normal litre per kg organic dry matter were obtained within 13 days. The specific methane production was higher and went faster compared to the fermentation of the untreated grassland silage. Elemental analyses of the press cakes showed a significant reduction in compounds detrimental for combustion. The ash...
