“…For water soluble sizes such as PVA or certain gums such as Arabic gum, it is possible to wash the textile with high amounts of hot water. However, the water becomes polluted by the sizing agents and needs to be treated, recycled or used for gas generation [140].…”

The use of composite materials reinforced by flax fibres has been increasing steadily over the last 20 years. These fibres show attractive mechanical properties but also some particularities (naturally limited length, presence of a lumen, fibres grouped in bundles in the plant, complex surface properties and composition). An analysis of the available literature indicates that the quality of the composite materials studied is not always optimal (high porosity, incomplete impregnation, heterogeneous microstructure, variable fibre orientation). This paper reviews published data on the specific nature of flax fibres with respect to manufacturing of biocomposites (defined here as polymers reinforced by natural fibres). All the important steps in the process which influence final properties are analyzed, including the plant development, retting, fibre extraction, fibre treatment, preform preparation, available manufacturing processes, the impregnation step, fibre cell wall changes during processing and fibre/matrix adhesion.

“…The practical application of biogas production installations does not exclude on-going development and improvement, which is evidenced by the latest reports [6,12,13]. Irrespective of the direction of research related to the development of biogas production technologies, three areas of research activity can be distinguished: (i) laboratory-scale experiments [1,8,14], (ii) semi-industrial scale experiments [15] and (iii) pilot experiments in industrial installations [16][17][18]. Since scientific research is inherently associated with a large number of experiments (multifarious aspects investigated in many repetitions), the technical possibilities of conducting such investigations in large-scale installations pose a problem.…”

The aim of this study was to develop a methodology to investigate the biofermentation process in small-volume fermenters. Dark serum bottles with a volume of 100-120 mL, tightly sealed with a rubber septum, were used as bioreactors. The optimum measurement conditions in this type of bioreactor comprise: (i) filling two-thirds of the maximum volume with a suspension; (ii) a 2% bioreactor loading (on a dry basis) and; (iii) the daily equalization of pressure by removing the biogas through the septum pierced with a syringe needle and the intensive mixing of the remaining suspension. The methane yield (quantity and dynamics) obtained in this type of bioreactor is analogous to that of industrial bioreactors or large-scale laboratory bioreactors. The use of small-volume bioreactors that can be incubated will facilitate the preliminary selection of analysed systems and provide an indication of those that should be investigated in large-scale bioreactors.
