Xenon is contained within articles of manufacture such as light bulbs. Described herein are an apparatus, system, a method to capture and collect the xenon contained in articles of manufacture such as defective light bulbs for recovery and/or reuse.

The invention relates to an apparatus for comminuting of material. The apparatus includes a first conveyor structure with a first conveyor surface, a second conveyor structure with a second conveyor surface, and in which apparatus the first conveyor surface and the second conveyor surface are set facing each other. The conveyor surfaces are arranged to define a comminuting space in the apparatus, The apparatus has means for bringing the conveyor surfaces in a movement in the direction of movement D where the two conveyor surfaces placed to face each other are arranged to move from a first end of the conveyor structures towards a second end of the conveyor structures. The conveyor surfaces positioned to face each other are placed in a convergent manner so that the gap between the conveyor surfaces narrows when examined in the movement direction of the conveyor surfaces, so that the advancing movement of the conveyor surfaces is arranged to bring about compression in the material being comminuted. In the invention, the conveyor surfaces are in a double-converging manner so that in addition to said convergence in the movement direction, the conveyor surfaces are additionally placed in a convergent manner so that the gap between the conveyor surfaces also narrows in the transverse direction in relation to the movement direction, said comminuting space thus becoming double-converging.

The present disclosure relates to a physically pretreated biomass composition capable of membrane filtration treatment in a biomass solid-liquid separation process, and a method for preparing sugar therefrom.

The physically pretreated biomass composition is very useful for the biomass treatment process because MF clogging phenomena do not occur through specific physical pretreatment (attrition milling) of herbaceous biomass and because MF passage speed is improved such that MF can be used in the biomass solid-liquid separation process.

Methods and systems for reducing an average particle size of blackwater solids is disclosed. A vessel is configured to receive a blackwater stream through a one-way inlet. The one-way inlet is configured to allow the blackwater stream into the vessel and prevent backflow. The blackwater stream contains blackwater solids and water. A device in a bottom portion of the vessel is configured to receive the blackwater and comminute the blackwater solids. A recirculating pump is configured to recirculate the blackwater stream under pressure through the device until the average particle size of the blackwater solids is reduced below a size threshold, resulting in a sized blackwater stream.

The present invention relates to methods for producing nanoparticle and microparticle powders of a biologically active material which have improved powder handling properties making the powders suitable for commercial use using dry milling processes as well as compositions comprising such materials, medicaments produced using said biologically active materials in particulate form and/or compositions, and to methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials administered by way of said medicaments.
