| This work studied the anaerobic digestion of brown juice, a liquid residual stream generated from biomass fractionation in a green biorefinery. Biomethane potential batch tests and inhibition studies of brown juice were performed during continuous processing in an upflow anaerobic sludge blanket reactor. Prolongation of the lag phase in the batch tests with increasing substrate/inoculum ratio suggested initial inhibition, which was, however, overcome by adaptation. This was indicated by high final methane yields, which were close to the theoretical maximum of up to 500 L-CH4 kg-VS−1, achieved after 15 days for most of the set-ups. Reactor operation at the organic loading rate of 13.9 g-COD L−1 day−1 and hydraulic retention time of 3 days revealed methane... |

| Nowadays, the organic farming sector is growing at a fast pace in Europe while needs to face the lack of organic protein sources and in particular, feeding monogastric animals is becoming more and more urgent. Green biorefinery concepts might become the suitable solution for the sustainable production of organic protein-rich feeds from green crops. In this context, red clover, clover grass, alfalfa and oilseed radish were studied as possible feedstocks for the development of an organic biorefinery system in Northern Europe. For this purpose, the green crops were processed into a nitrogen-rich protein concentrate, a fiber-rich press cake, and a residual stream of soluble nutrients (brown juice). The process, which involved a novel protein refining technique... |

| Nowadays, the organic farming sector is rapidly increasing in order to meet the increasing demand for organic products. However, the scarce availability of organic feed for monogastric animals together with the lack of organic fertilizers are challenging the development of this sector. In this context, a Danish project called Organofinery is focusing on developing a green biorefinery platform for the production of organic protein-rich feed for monogastric animals, of biogas and of organic fertilizer. In the Organofinery concept, the freshly harvested green biomass is separated by a screw press into a green juice and a press cake. Soluble sugars contained in the green juice are fermented by specific lactic acid bacteria, leading to a drop of the pH and... |

| Nutrient recovery from organic green biomass after processing in a green biorefinery concept for the production of protein feed, biogas and fertilizer for organic farming was investigated. Mass balances in terms of wet weight, TS, VS, C, N, P, K and S were evaluated for processing red clover and clover grass into protein concentrate, press cake and brown juice according to the green biorefinery concept. The analysis was based on mass flows and composition of each of the fractions produced. Depending on the biomass, between 60-79% of C and between 52-63% of N, P and S in the fresh biomass were found in the press cake, while only 6-10% of C, 8-15% of N, but up to 27% of P and up to 26% of S were found in the brown juice. In contrast, less than 45% of K was... |

| Organically grown red clover was investigated as a resource for organic feed by combination of protein extraction and anaerobic digestion of the sub-products. Extraction of proteins revealed a very favorable amino acid composition for the use as poultry feed. The residual 89% of organic matter, as solid press cake and brown juice was subjected to anaerobic digestion to produce biogas and fertilizer. Specific methane yields of 225±62 and 487±30 ml CH4/g VS were obtained for press cake and brown juice, respectively. No distinct inhibition was detected but adaptation of microorganisms in the case of the press cake and gradual increase of the substrate load in the case of the brown juice were beneficial to achieve efficient conversion of both fractions during... |

| Difficulties with the supply of organic protein feed; low crop yields and low value of leguminous forage crops and a lack of organic fertiliszers are nowadays threesome of the major challenges faced by farms with monogastric animals. Thus, forcing the organic farmers to import feed and manure forom conventional farms. The main idea of the OrganoFinery project is to develop a green biorefinery concept where the same organic crop is utilizsed for animal feed, fertilizser and energy production in the form of methane, coping in this way with those challenges. One of the aims of the project includes the identification of crops that can be grown on organic arable farms, where there is generally a significant lack of nitrogen. Particularly legumes are... |
